Paul BakausandClaude Opus 4.7 e2008f8091 test: align hero-eyebrow-chip fixture with relaxed rule gates
b9bf496 intentionally relaxed two gates in checkHeroEyebrow:
- removed the heading-size ≥ 48px anchor (modern hero h1s use
  clamp/vw/var that jsdom can't resolve)
- raised the eyebrow text ceiling from 30 to 60 chars

Two fixture cases that satisfied the negative side of the old gates
now match the rule:

- "Body-Sized Heading Below Eyebrow" — 24px h1 with tracked-caps
  label above. Per the rule's stated intent ("a tiny tan label
  directly above any h1 is the antipattern regardless of how big
  the h1 ends up"), this is a flag.
- "Long Uppercase Sentence Above Hero" — 46-char tracked-caps label
  is under the new 60-char ceiling, so still eyebrow-shaped.

Both cases moved from the should-pass column to should-flag, with
case descriptions rewritten to explain the gate they exercise.

Paul BakausandClaude Opus 4.7 f36d1ac2d9 site + build: bump rule count to 29, strip changelog from detector check
Two changes:
- site/pages/index.astro: three live mentions of "28 rules / checks"
  bumped to 29 after the body-text-viewport-edge rule landed in
  b9bf496.
- scripts/build.js: the detection-count validator was reading the
  unstripped content, so historical counts inside changelog entries
  (e.g. "28 rules" from an older release note) were flagging against
  the current detector total. The command-count check already strips
  the changelog ul; the detection check now does the same.

Paul BakausandClaude Opus 4.7 a31f11e700 PRODUCT.md: widen audience beyond developers
Designers, product managers, and engineers all use AI coding tools
and want better design output. Keeping the audience narrow to
"frontend and full-stack developers" understates who the skill is
actually for. Also retitles "developer" to "user/builder" in the
purpose statement.

Paul BakausandClaude Opus 4.7 d69757d13e brand: inverse-test + cultural-symbol palette guardrail
Two additions to the brand register reference:

- Inverse slop test: describe the page the way a competitor would
  describe theirs. If that sentence fits the modal landing page in
  the category, restart.
- Palette guardrail: when a cultural-symbol palette is the obvious
  pull, reach past it. Let cultural reading come from typography,
  imagery, and copy.

Harness mirrors regenerated; some also catch up to the image-
verification paragraph from e3ad2ef that hadn't been re-synced.

Paul BakausandClaude Opus 4.7 fd3eed9f3b build: native subagent pipeline + Codex-only asset producer
Adds an agent cross-compile pipeline alongside the existing skill
pipeline. Sources live at skill/agents/*.md; providers that declare
agentFormat (codex-toml, claude-md) emit native subagent files. An
optional providers: <list> field on an agent gates which harnesses
get a copy; default (no field) ships everywhere.

The impeccable-asset-producer agent is opt-in to Codex only. It's
useful for Codex's native image generation path and is untested
elsewhere; Claude has no native image gen anyway.

Paul BakausandClaude Opus 4.7 b03d7515c8 craft.md: tighten verbose passages, de-codex Step 6, cut redundancies
Cumulative reduction: 218 → 155 lines (-29%).

Step 0: drop the "Why this matters" paragraph at the end. The body of
Step 0 already makes the framework-pick point; the paragraph just
re-explains it with extra rhetoric.

Step 1: replace the 4-sentence "you must end your response" block with a
single line. The original said the same thing three different ways.

Step 3: trim the conditional / defensive scaffolding (Purpose subsection,
"do not skip because the eventual UI is semantic..." paragraph,
duplicated approval-loop guidance). Mock fidelity inventory preserved.

Step 4: drop the "keep UI text semantic" sentence; it duplicates Step 5's
"Semantic first" rule. The rasterized-vs-semantic decision rule stays.

Step 5: tighten each production-bar bullet to bold-lead + specifics
format. All 15 rules preserved (real content, mock ingredients, semantic
first, spacing/alignment, typography, state coverage, interaction quality,
icon set, build pipeline, image URL verification, optimized imagery,
premium motion, maintainability, technical cleanliness, ask-when-uncertain).

Step 6: rewrite around "look at what you built like a designer would —
your eyes are whatever the harness gives you." Drops Codex-specific
"In Codex, use browser-use" bias. Drops the verbose 3-step Read pattern
(condensed to one sentence). Drops the 1-8 numbered checklist (replaced
by a tight paragraph). Keeps the load-bearing rules: read the PNG,
don't fabricate iteration, mock fidelity reference, exit bar = studio
defensibility.

Step 7: drop the closing "Iterate based on feedback. Good design is
rarely right on the first pass" preachy filler.

All em-dashes converted to semicolons / colons / periods to satisfy
the skill prose validator.

Paul BakausandClaude Opus 4.7 b9bf496e35 detector: body-text-viewport-edge rule + OKLCH/var-resolution + anchor-inherit FP fixes
New rule: body-text-viewport-edge flags body paragraphs that render flush
against the left/right viewport edges (no container padding). Tested via
the new tests/fixtures/antipatterns/body-text-viewport-edge.html fixture
(3 flag cases, 5 pass cases) and the test in detect-antipatterns-browser.

False-positive class fixes — all jsdom-mode only (real browsers resolve
the cascade correctly so these gates stay inert there). Five related
gaps that compounded into ~14× spurious contrast findings on Tailwind v4
pages with OKLCH color tokens:

  • OKLCH parser. jsdom returns the literal "oklch(...)" string from
    getComputedStyle; the detector now converts to sRGB via Björn
    Ottosson's matrices. Handles Tailwind v4's compact minified form
    "oklch(21.5%.02 50)" (no space after %).
  • var() resolution. resolveBackground + checkElementColors now
    accept the existing customPropMap and parse `var(--color-paper)`
    etc. as proper RGB via the new parseColorResolved helper.
  • bg-color before bg-image. The old order bailed on any gradient
    ancestor before checking for a solid background-color underneath,
    causing the body's decorative paper-grain gradient to be measured
    against instead of the page's actual `bg-paper` cream.
  • body/html-level gradient → white fallback. When the only opaque
    ancestor we can read is body/html with a gradient overlay (and
    jsdom can't decompose `background: var(--paper) gradient` to
    extract the solid color), return white instead of falling through
    to resolveGradientStops — which was picking up paper-grain noise
    colors and using them as the bg.
  • Anchor-inherit workaround for jsdom :link UA specificity.
    Tailwind v4's preflight declares `a { color: inherit }` (0,0,1).
    jsdom's UA stylesheet has `:link { color: blue }` at (0,1,1) and
    wins the cascade. Real Chrome wraps :link in :where() (0,0,0) so
    the page rule wins. When the page declares the inherit rule AND
    we see jsdom's default `rgb(0,0,238)` on an anchor, walk to the
    nearest non-anchor ancestor and use its color.
  • Alpha-fallback safety gate. When text has alpha<1 AND we couldn't
    find an opaque ancestor (effectiveBg null), skip the contrast
    finding. Covers any remaining FP class the deeper fixes miss.

Verified end-to-end against an Opus iter-1 artifact on Tailwind v4 with
14 cream/cream FPs + 2 blue-link UA FPs before; 0 findings after, while
the color.html fixture's 12 real low-contrast cases continue to flag
(verified via direct detectHtml calls).

cli/engine/detect-antipatterns-browser.js is the generated browser
distribution — regenerated from .mjs via scripts/build-browser-detector.js
(no manual edits to the generated file).

Paul BakausandClaude Opus 4.7 e3ad2eff25 craft + brand: framework foundation, build-pipeline respect, image verification
Three closely-linked additions surfaced by an eval-harness session
investigating why the agent always shipped flat single-file HTML and
zero imagery on greenfield brand briefs.

1. craft.md gains a new Step 0 "Project Foundation" before Shape.
   Detects existing framework / component library / icon set and
   uses what's there. Greenfield: ask the user via AskUserQuestion
   with sensible defaults framed by the brief (Astro for content/
   brand sites, SvelteKit/Next/Nuxt for app surfaces, single
   index.html only for one-shot demos). Skipping the framework
   decision and writing flat HTML "to satisfy the spec" produces
   work that reads as a 2018 prototype regardless of visual
   quality.

2. craft.md Step 5 production bar gains two bullets:
   - Respect the build pipeline. Edit source files and run the
     project's `npm run build`; do not write to build/ / dist/ /
     .next/ directly with cat/heredoc/Bash redirects. Bypassing
     the pipeline skips asset hashing, image optimization, code
     splitting, and CSS extraction.
   - Verify external image URLs before referencing them. Use an
     image-search MCP, web-fetch tool, or browser if available;
     guessed photo IDs ship as broken-image placeholders.

3. brand.md "Imagery" section:
   - Generalizes the Unsplash URL guidance to "verify URLs
     before referencing them" with a hierarchy: image-search MCP
     > web-fetch > confidence-restricted manual selection >
     fewer photos.
   - Tightens the tech/dev-tool exception. Old line "zero imagery
     can be correct" gave models a permission slip. New framing
     keeps the underlying truth (typography + code + diagrams
     primarily carry voice) but raises the floor: imagery still
     earns its place when it serves the brief, and skipping it
     requires naming the typographic/diagrammatic move that's
     carrying the visual weight instead. "Zero imagery is the
     failure mode of laziness, not restraint."

Eval-harness corpus that prompted this: 19/19 brand landing tasks
shipped 0 images each, including ones where Opus had taste enough
to break the dev-tool color default lane. The skill needs to teach
both halves of the decision; the harness shouldn't have to nudge.

Paul BakausandClaude Opus 4.7 8f98f36e3d craft.md Step 6: Reading the screenshot is the inspection, not taking it
A v4 eval run took 4 targeted screenshots (hero, mobile, tablet,
query-section) and then never Read any of them back. The agent treated
browser_screenshot itself as "I inspected" and shipped without the
multimodal feedback loop ever closing. Detector caught the resulting
slop (5+ side-tab violations) on adjacent runs that did the same thing.

Step 6 now spells out the pattern explicitly: take the screenshot,
then Read the resulting PNG so its image content enters the
conversation as multimodal input, then critique what you actually see
in the image. With a check: "if your critique could have been written
without looking at the image, you didn't look at the image."

Validated with v5b: agent took 6 screenshots, Read all 6 back, and
shipped with zero detector findings (vs the previous greenfield runs
that hit 1-12 findings each).

Paul BakausandClaude Opus 4.7 ea2e372564 skill: strip gate ceremony; require shape pause; allow compact briefs
The setup gate table and IMPECCABLE_PREFLIGHT banner pushed every
craft run through ritual restatement (PRODUCT.md → original prompt
→ round 1 → round 2 → 70-line "confirmed brief" → critique → summary,
all saying the same thing). Replaced with imperative prose that still
demands the same work but skips the user-facing telemetry.

Specifically:

SKILL.md
- Drop the Setup gate table and IMPECCABLE_PREFLIGHT banner.
- Keep the imperative steps explicitly: load context, identify register
  and load brand.md or product.md, AND load the matching command
  reference (craft.md / shape.md / etc.) when a sub-command is invoked.
  The command-reference step is non-negotiable; without craft.md loaded
  the agent skips the shape-and-confirm pause.

craft.md
- Drop the Build Gate / Craft Contract formal sections; replace with
  one paragraph stating prerequisites.
- Step 1 explicitly requires ending the response after presenting the
  shape output; the user must confirm before any code lands. Allows a
  compact 3-5 bullet brief when the prompt + PRODUCT.md already pin
  direction (full 10-section structure reserved for genuinely
  ambiguous tasks).
- Step 3 image gate skips silently when image generation isn't
  natively available; no user-facing announcement.
- Step 6 explicitly legitimizes "first pass clean, shipping" as a
  valid endpoint and bans inventing fake defects to demonstrate
  iteration.

shape.md
- Cap discovery at 1 round by default; second round only when first
  leaves material gaps.
- Adds an "assert-then-confirm, not menu-with-escape" rule: when
  PRODUCT.md and the prompt make one option obvious, name it and ask
  for confirm or override instead of enumerating "Restrained /
  Committed / Or something else?" as a real choice.
- Phase 2 brief has two forms now: compact (default for clear briefs)
  and full structured (genuinely ambiguous). Open Questions can't
  double as leading-with-Recommend; if you'd write "Recommend: X",
  decide X.
- Image gate same as craft.md.

Validated end-to-end with a Haiku skill-on observability run: agent
loads craft.md plus the brief's recommended implementation refs,
pauses for one productive question (accent color, trace fidelity,
CTA), and ships an artifact with zero side-tab violations vs. the
original v1 baseline. Cost trades up modestly for that quality.

Paul BakausandClaude Opus 4.7 a8b032d362 skill: drop quality tiers, keep the real brand-craft guardrails
Codex's craft/brand pass introduced fast/ship/showpiece "quality bars"
plus brand-specific build gates, asset ledgers, sub-agent review, and
self-graded fallback labels. In practice those tiers became escape
hatches rather than craft pressure: the final output should always be
10/10, and the real decision points are splashiness and maximalism, not
quality.

Removed:
- All quality-bar / showpiece / fast / ship framing in shape.md and craft.md
- Standalone Brand Direction (#4) and Asset Requirements (#10) sections
  in shape's brief; renumbered back to 1-10
- The Brand hard rules section in brand.md (folded its real prohibitions
  into the existing Imagery and Brand bans sections)
- Brand-specific build-gate item, mock-fidelity bullet, production-bar
  bullet, present-step bullet in craft.md
- Asset ledger ceremony in craft Step 4
- Review-only sub-agents and "self-reviewed fallback, not independently
  validated" machinery in craft.md and polish.md
- The For brand surfaces, assess hard failures subsection in polish.md
  and the brand checklist row
- tests/brand-showpiece-reference.test.mjs (and its package.json wiring)

Kept (the real nuggets):
- Asset-substitution prohibition: image-led briefs ship real/generated
  assets or canvas/SVG/WebGL, not generic CSS panels, cards, bullets,
  or copy
- Repeated tiny uppercase tracked kicker labels as a brand ban
- Detector/QA output is defect evidence only, never proof of quality
- "What visual assets are real content here?" discovery question
- Inspect each major section individually for brand and long-form work
- repeated-section-kickers detection rule + fixture
- CLI improvements (JSON to stdout, -json/-fast aliases, severity field)
- critique.md: npx impeccable detect --json fix

Harness output dirs refreshed via bun run build. Full test suite (186)
passes.

e587004ee4 Refactor: cleaner top-level directory structure (#138)
* refactor(content): merge content/site/ into site/content/

Phase 1 step 1 of the directory restructure. The dual content tree was
called out in CLAUDE.md as cleanup; both trees were already in sync
except for anti-patterns-catalog.js, which moves to site/data/.

- Delete content/site/skills/ and content/site/tutorials/ (duplicates of
  site/content/, which is what Astro's content collection actually reads).
- Move content/site/anti-patterns-catalog.js -> site/data/.
- Update scripts/lib/sub-pages-data.js and scripts/build.js to read from
  site/content/ and site/data/.
- Drop content/site/ from validateProse target list (site/content was
  already there).
- Rewrite the "Two content trees" section in CLAUDE.md as a single-tree
  pointer; update stale dev-server text mentioning the deleted
  server/index.js.

Tests: 186/186 pass. Skills build: clean.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* refactor(skill): rename source/skills/impeccable/ -> skill/

Phase 1 step 2 of the directory restructure. The path was redundantly
nested ("source/" wrapper plus "skills/impeccable/" — singular content
hidden behind the plural). Collapses to flat skill/SKILL.md +
skill/reference/ + skill/scripts/.

- Move source/skills/impeccable/ -> skill/.
- Rewrite scripts/lib/utils.js readSourceFiles(): drop the multi-skill
  iteration (CLAUDE.md commits to a single user-invocable skill); read
  skill/SKILL.md directly.
- Update scripts/build.js, scripts/generate-og-image.js, and the
  sub-pages data layer to point at skill/.
- Update tests/lib/utils.test.js: drop the "multi-skill" and "dir-name
  fallback" cases, update single-skill paths to skill/.
- Update tests/build.test.js similarly: drop "multiple skills"
  integration test, update paths.
- Update non-glob path joins in tests/framework-fixtures.test.mjs,
  tests/live-e2e/session.mjs, tests/live-e2e/agents/llm-agent.mjs,
  tools/live-loop.mjs.
- Update prose/text references in CLAUDE.md, AGENTS.md, DEVELOP.md,
  README.md, scripts/lib/sub-pages-data.js, bin/commands/skills.mjs,
  site/data/anti-patterns-catalog.js, site/pages/docs/[...slug].astro,
  docs/adr-live-variant-mode.md, docs/plans/.

Eval framework note: the separate impeccable-evals repo reads
../impeccable/source/skills/impeccable/ and needs a coordinated
rename to ../impeccable/skill/.

Tests: 186/186 pass. Skills build: clean.

* refactor: rename docs/ -> notes/

Phase 1 step 3 of the directory restructure. The internal docs/ dir
(ADRs and plans) clashed with the site's /docs route. Renaming it
"notes/" makes the difference unambiguous: notes/ is project-internal
process, /docs is the user-facing route under site/pages/docs/.

No code references the dir; the rename is a clean git mv.

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* refactor(site): move public/ under site/public/

Phase 2 step 4 of the directory restructure. Public assets and the
Astro publicDir now live alongside the rest of the site, so site/
is fully self-contained for static content.

- git mv public site/public.
- astro.config.mjs: add publicDir: './site/public'. Astro defaults to
  ./public at the project root, so the override is required.
- scripts/build.js: write generated _data, _headers, _redirects,
  _routes.json, and js/detect-antipatterns-browser.js into
  site/public/. Also delete the dead _REMOVED() Bun static-site
  builder (replaced by Astro at #130; the placeholder no longer earns
  its keep).
- scripts/build.js validateProse: replace the stale public/index.html
  reference (deleted at the Astro migration) with site/pages/index.astro
  in the count-validation file list, restoring homepage drift detection.
- scripts/generate-og-image.js: write OG image into site/public/.
- scripts/screenshot-antipatterns.js: read examples from + write
  screenshots to site/public/antipattern-{examples,images}/.
- scripts/lib/sub-pages-data.js: load command demos from
  site/public/js/demos/commands.
- .gitignore: rename the public/* generator-output entries to
  site/public/*.
- CLAUDE.md: refresh CSS/data-file paths (still pointing at the old
  pre-Astro public/css/ + public/js/ tree), point the changelog and
  command-add checklists at site/pages/index.astro and
  site/scripts/data.js + site/scripts/components/framework-viz.js.

Cloudflare Pages note: functions/ stays at the repo root because
CF Pages auto-discovers it there with no configuration knob to
relocate. Moving it under site/ would either break deployment or
require a build-time copy step that adds more complexity than the
cleanup is worth.

Tests: 186/186 pass. Skills + site build clean. _headers,
_redirects, _routes.json, _data/ all land in build/ correctly.

* refactor(cli): consolidate bin/ + src/ + lib/ under cli/

Phase 2 step 5 of the directory restructure. The CLI surface was split
across three top-level dirs whose names were easy to mistake for each
other (especially src/ vs source/ pre-step-2). Consolidates under cli/.

- git mv bin -> cli/bin (CLI entry + skills sub-command)
- git mv src -> cli/engine (detect-antipatterns engine + browser variant)
- git mv lib -> cli/lib (download-providers helper)

Update package.json:
- bin.impeccable: cli/bin/cli.js
- main + exports: cli/engine/detect-antipatterns.mjs and the
  ./browser variant
- files: ["cli/", "LICENSE"]

Update internal references:
- cli/bin/cli.js: dynamic import points at ../engine/, package.json
  read goes one level deeper (../../package.json).
- functions/api/download/[type]/[provider]/[id].js + bundle/[provider].js:
  cli/lib/download-providers.js path.
- scripts/build.js, scripts/build-browser-detector.js,
  scripts/build-extension.js: cli/engine path constants.
- scripts/lib/sub-pages-data.js, scripts/lib/utils.js, skill/scripts/
  live-server.mjs: comment refs.
- tests/detect-antipatterns{,-browser,-fixtures}.test.{js,mjs},
  tests/windows-path-fix.test.js: import + read paths.
- AGENTS.md, CLAUDE.md: doc paths.

Verified:
- npx node cli/bin/cli.js --version, --help, detect --help all work.
- bun run build, bun run build:browser, bun run build:extension all
  clean. Browser detector lands at cli/engine/detect-antipatterns-browser.js;
  extension/detector/detect.js still emits to the same location.
- bun run test: 186/186 pass.

* fix: update browser-detector paths missed in cli/ rename

Bugbot caught two runtime path leaks where the comment got renamed
to cli/engine/ but the actual code still used the old src/ segment.

- skill/scripts/live-server.mjs: detectPaths array now joins cli, engine,
  detect-antipatterns-browser.js for both the repo-relative lookup
  (4 dirs up from .claude/skills/impeccable/scripts/ to repo root) and
  the npm node_modules fallback. Without this fix, the detection
  overlay would silently not load during live-server sessions.

- scripts/build.js: the post-build copy of the browser detector into
  site/public/js/ was reading from src/. The if (fs.existsSync(...))
  guard meant the copy was silently skipping, so antipattern-examples
  pages would 404 on /js/detect-antipatterns-browser.js once the site
  was deployed.

Tests: 186/186 pass. Build clean. site/public/js/detect-antipatterns-browser.js
re-emits as expected.

* fix: cleanup-deprecated import path missed an extra .. in cli/ rename

Bugbot caught three call sites in cli/bin/commands/skills.mjs that
import '../../skill/scripts/cleanup-deprecated.mjs'. Pre-rename, that
was correct from bin/commands/ (one parent to bin/, one to repo root).
After moving the file from bin/commands/ to cli/bin/commands/, the
path is one directory deeper, so it needs three .. segments to reach
the repo root. Without the fix, every cleanup invocation throws on
import and gets swallowed by the surrounding try/catch — silent skip.

cli/bin/cli.js's package.json read already uses '../../package.json'
(the same depth pattern), confirming three levels is correct.

Verified: dynamic import resolves and exports the expected functions.

* chore: sweep stale path/file references missed in the restructure

Same root cause as the two bugbot finds: some references in moved or
related files weren't tracked because they didn't match a simple
sed pattern. Caught the rest by walking each moved dir's depth and
each Astro-migration deletion.

Stale path references (post-Astro migration, missed earlier):
- CLAUDE.md: legacy URL redirects "live in server/index.js" -> point
  at the actual sources (scripts/build.js generateCFConfig +
  site/public/_redirects).
- AGENTS.md: counts.js path (public/ -> site/public/), changelog file
  (public/index.html -> site/pages/index.astro), screenshots note
  (public/ -> site/), source-of-truth dirs (source/, src/ -> skill/,
  cli/).
- tests/detect-antipatterns-browser.test.mjs: comment about routes
  "in server/index.js".
- skill/reference/live.md: workflow.css example for "this repo" was
  pre-Astro (public/css/) -> site/styles/. (User-project Vite/Next
  example unchanged.)

Stale path that pointed at moved files:
- tests/skills-cli.test.js: CLI path was '..', 'bin', 'cli.js'; now
  '..', 'cli', 'bin', 'cli.js'. Test isn't wired into bun run test
  but it would have failed if invoked.

Dead files (orphaned by Astro migration, never cleaned up):
- tests/server/download-validation.test.js: imported from
  ../../server/lib/{validation,api-handlers}.js which were deleted in
  b8f09c8. Test was a silent failure waiting to happen.
- scripts/lib/render-markdown.js: 156-line module with zero consumers
  (the only caller, scripts/lib/render-page.js, was deleted in the
  Astro cleanup).
- scripts/build.js: dead commented-out generateSubPages import.

Tests: 186/186 pass. Build clean.

* fix(build): remove invalid Corepack packageManager spec

Cloudflare Pages rejects the build with `Unsupported package manager
specification (bun@1.3.11)`. The packageManager field follows
Corepack's syntax which only validates npm/pnpm/yarn — `bun@X.Y.Z`
parses as a malformed Corepack directive even though Bun itself
treats it as a hint.

Pre-existing on main since d874af0 (CF Pages deploy on main also

## Setup
Before any design work or file edits, pass these gates. Skipping them produces generic output that ignores the project.
Before any design work or file edits:
| Gate | Required check | If fail |
|---|---|---|
| Context | The PRODUCT.md / DESIGN.md loader result is known from `node .agents/skills/impeccable/scripts/load-context.mjs`. | Run the loader before continuing. |
| Product | PRODUCT.md exists and is not empty or placeholder (`[TODO]` markers, <200 chars). | Run `$impeccable teach`, refresh context, then resume. Never synthesize PRODUCT.md from the user's original prompt alone. |
| Command | The matching command reference is loaded when a sub-command is used. | Load the reference before continuing. |
| Craft | `$impeccable craft` has a user-confirmed shape brief for this task. `teach` / PRODUCT.md never counts as shape. | Run `$impeccable shape` and wait for explicit brief confirmation. |
| Image | Required visual probes / mocks are generated or skipped with a reason. | Resolve the image-generation gate in `shape.md` or `craft.md` before code. |
| Mutation | All active gates above pass. | Do not edit project files yet. |
1. Load context (PRODUCT.md / DESIGN.md) via the loader script.
2. Identify the register and load the matching register reference (brand.md or product.md).
3. **If the user invoked a sub-command (e.g. `craft`, `shape`, `audit`), load its reference file too.** This is non-negotiable: `craft` without `craft.md` loaded means you'll skip the shape-and-confirm step the user expects.
Codex-style agents must state this before editing files:
```text
IMPECCABLE_PREFLIGHT: context=pass product=pass command_reference=pass shape=pass|not_required image_gate=pass|skipped:<reason> mutation=open
```
For `$impeccable craft`, `shape=pass` is only valid after a separate user response approving the shape design brief, or when the user provided an already-confirmed brief in the request. Do not mark `shape=pass` after writing PRODUCT.md, summarizing assumptions, or drafting an unconfirmed brief yourself.
Other harnesses should follow the same checklist when they can expose this state.
Skipping these produces generic output that ignores the project.

# Craft Flow
Build a feature with impeccable UX and UI quality through a structured process: shape the design, land the visual direction, build real production code, then inspect and improve in-browser until the result meets a high-end studio bar.
Build a feature with impeccable UX and UI quality: shape the design, land the visual direction, build real production code, inspect and improve in-browser until it meets a high-end studio bar.
## Build Gate
Before writing code, you need: PRODUCT.md loaded, register identified and the matching reference loaded, and a confirmed design direction for this task (either from `shape` or supplied by the user). PRODUCT.md is project context, not a task-specific brief.
Craft cannot build until all of these are true:
Treat any approved visual direction (generated mock or stated reference) as a concrete contract for composition, hierarchy, density, atmosphere, signature motifs, and distinctive visual moves. Don't let mocks replace structure, copy, accessibility, or state design. But if the live result lacks the approved direction's major ingredients, the implementation is wrong.
1. PRODUCT context is valid and current.
2. The shape design brief is explicitly confirmed by the user for this task, unless the user already provided a confirmed brief.
3. Implementation references from the brief are loaded.
4. The shape visual probe decision is recorded: generated, skipped with reason, or already resolved.
5. The north-star mock decision is recorded: generated, skipped with reason, or not applicable.
## Step 0: Project Foundation
PRODUCT.md and `teach` answers do **not** satisfy the shape gate. They are project context only. A compact self-authored brief does not satisfy the shape gate either. `shape=pass` requires a separate user response approving the shape brief or an already-confirmed brief supplied by the user.
Before shape, before code: figure out what kind of project you're working in.
Invalid image-skip reasons include: "the final implementation will be semantic HTML/CSS/SVG", "the diagram should stay editable", "a raster mock would not be used directly", or "the product is fictional." Generated probes and mocks are direction artifacts; they are not implementation assets.
Look at the working directory. Run `ls`. Check for:
## Craft Contract
- An existing framework: `astro.config.mjs/ts`, `next.config.js/ts`, `nuxt.config.ts`, `svelte.config.js`, `vite.config.js/ts`, `package.json` with framework deps, `Cargo.toml` + Leptos/Yew, `Gemfile` + Rails. **If found, use it.** Do not start a parallel build, do not introduce a second framework, do not write to `dist/` or `build/` directly. Whatever pipeline the project has, respect it.
- An existing component library or design system: `src/components/`, `app/components/`, a `tokens.css` / `theme.ts`, an `astro.config` `integrations`. Read what's there before adding to it.
- An existing icon set: `lucide-react`, `@phosphor-icons/react`, `@iconify/*`, hand-rolled SVG sprites in `assets/icons/`. **Use what's already in the project**; don't introduce a second set.
Craft is not a first pass. It is a loop with these required artifacts:
If the directory is empty (greenfield), don't pick a framework silently. Ask the user via the AskUserQuestion tool, with sensible defaults framed by the brief:
1. Confirmed design brief from `shape`.
2. Approved visual direction, from generated probes / mocks when image generation is available.
3. Mock fidelity inventory: the visible ingredients from the approved direction that must survive into code.
4. Semantic, functional implementation using the project's real stack and conventions.
5. Browser evidence across relevant viewports.
6. At least one critique-and-fix pass after the first browser inspection, unless the first pass has no material defects.
```text
What should this be built on?
- Astro (default for content-led brand sites, landing pages, marketing surfaces)
- SvelteKit / Next.js / Nuxt (when the brief implies an app surface or significant interactivity)
- Single index.html (one-shot demo, prototype, or a deliberately framework-free experiment)
```
Do not let generated mockups replace interface structure, copy, accessibility, responsive behavior, or state design. But do treat the approved mock as a concrete visual contract for composition, hierarchy, density, atmosphere, signature motifs, image needs, and distinctive visual moves. "North star" means "preserve the important visible ingredients in semantic code," not "use it as loose mood."
Default: Astro for brand briefs, the project's existing framework for product briefs. Ask once; don't re-ask mid-task.
## Step 1: Shape the Design
Run $impeccable shape, passing along whatever feature description the user provided.
Run $impeccable shape, passing along whatever feature description the user provided. Shape is **required** for craft; it is what produces a confirmed direction.
Wait for the design brief to be fully confirmed by the user before proceeding. The brief is your blueprint, and every implementation decision should trace back to it.
Present the shape output and stop. Wait for the user to confirm, override, or course-correct before writing code.
If this craft run resumed after `teach` created PRODUCT.md, run shape now. Do not treat the teach interview, PRODUCT.md, or a summary of project context as a substitute for shape. Shape is task-specific and must cover scope, content/states, visual direction, constraints, anti-goals, probes when applicable, and explicit brief confirmation.
If the user already supplied a confirmed brief or ran shape separately, use it and skip this step.
If the user has already run $impeccable shape and has a confirmed design brief, skip this step and use the existing brief.
When the original prompt + PRODUCT.md already answer scope, content, and visual direction with no real ambiguity, the shape output can be **compact** (3-5 bullets stating what you're building and the visual lane, ending with one or two specific questions or "confirm or override"). The full 10-section structured brief is reserved for genuinely ambiguous, multi-screen, or stakeholder-heavy tasks. Don't pad a clear brief into a long one to look thorough; equally, don't skip the pause to look efficient.

## Step 3: Land the Visual Direction (Capability-Gated)
Before implementation, generate high-fidelity visual comps when all of these are true:
Generate high-fidelity visual comps before implementation when all three are true:
- The work is **net-new** or visually open-ended enough that composition exploration will improve the build.
- The brief's scope is **mid-fi, high-fi, or production-ready**.
- The current harness has **built-in image generation capability** (for example, Codex with a native image tool). Do **not** ask the user to set up external APIs, shell scripts, or one-off tooling just to do this.
- The work is net-new or visually open-ended enough that composition exploration will improve the build.
- The brief's scope is mid-fi, high-fi, or production-ready.
- The harness gives you native image generation (Codex's `image_gen`, an equivalent MCP tool). Don't ask the user to set up external APIs.
When those conditions are met, this step is mandatory for **both brand and product work** in Codex and any harness with built-in image generation. Use native image generation; in Codex, use the built-in `image_gen` tool via the imagegen skill. If image generation is unavailable, do not ask the user to install APIs or tooling. State in one line that the image step is skipped because the harness lacks native image generation, then proceed.
Do not skip this step because the eventual UI should be semantic, editable, code-native, responsive, or accessible. Those are implementation requirements, not reasons to avoid visual exploration.
### Purpose
Use the mock step to find a stronger visual lane than code-first generation would reliably discover on its own. The brief remains authoritative on user, purpose, content, constraints, states, and anti-goals. The mock clarifies composition, hierarchy, density, typography, and visual tone.
When met, this step is mandatory for both brand and product work. If image generation isn't available, skip silently. "The eventual UI is semantic/code-native/accessible" is not a reason to skip; those are implementation requirements, not exploration ones.
### What to generate
Generate **1 to 3** high-fidelity north-star comps based on the confirmed brief. If shape already produced direction probes, use those results as input and generate a more resolved mock from the winning lane, not another unrelated exploration.
Generate **1 to 3** high-fidelity north-star comps from the confirmed brief. If shape already produced direction probes, resolve the winning lane further, not an unrelated exploration. Comps must differ in primary visual direction, not just color.

- For product work, still push hierarchy, topology, density, and tone, but keep the comps grounded in realistic product structure and states.
- For landing pages and long-form brand surfaces, show enough of the next section or second fold to establish the system beyond the hero.

### Mock fidelity inventory
Before building, inventory the approved mock's major visible ingredients:
Inventory the approved mock's major visible ingredients:
- Hero silhouette and dominant composition.
- Signature motifs: planets, devices, portraits, charts, route lines, insets, badges, or other memorable objects.
- Nav and primary CTA treatment.
- Section sequence visible in the mock, especially the second fold.
- Image-native content the concept depends on.
- Typography, density, color/material treatment, and motion cues.

For each ingredient, decide how it will be implemented: semantic HTML/CSS/SVG, generated asset, sourced project asset, icon library, canvas/WebGL, or an explicitly accepted omission. Do not substitute a different hero composition or new visual driver after approval unless the user approves the change.

Treat the mock as a north star, not a screenshot to trace. Don't rasterize core UI text. But if the live result lacks the mock's major ingredients, the implementation is wrong.
## Step 4: Asset Extraction (Need-Gated)
If the chosen direction includes image-native visual ingredients that would materially improve the implementation, generate them as separate assets before building.
If the approved direction needs raster assets, create them before building. Do not replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy.
Good candidates:
Use the native asset producer (`impeccable_asset_producer` in Codex, `impeccable-asset-producer` in Claude Code) to create clean assets from the hi-fi mock and crops. If you do not have explicit permission to use agents, stop and ask:
- stickers
- badges
- seals
- tickets
- graphic labels
- textures
- abstract objects
- decorative marks
- non-semantic scene elements
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
For travel, editorial, portfolio, venue, product showcase, entertainment, education, or any other image-led brand surface, visual assets are usually core content, not decoration. Do not ship abstract CSS panels where the approved mock or subject matter calls for real imagery, generated plates, illustrations, maps, product/object renders, or destination scenes.
Do not skip asset production or silently do it inline. Inline asset production is allowed only if the user declines subagents, the harness cannot spawn the authorized agent, or the user explicitly asks for single-thread mode.
Do **not** export assets for core UI text, navigation, body copy, or any structure that should stay semantic and editable in code.
Pass the approved mock, crop/contact-sheet paths, output directory, dimensions/formats, transparency needs, constraints, and avoid list to the asset producer. Attach image generation capability to the spawned agent when the harness supports it; do not load image-generation reference material into the parent thread first.
Usually **1 to 5** extracted assets is enough. If the design can be built cleanly in HTML/CSS/SVG, prefer that over raster assets. If the mock contains major visual content that cannot be built credibly in code, asset extraction is not optional.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; use real/generated/stock imagery when the mock or subject matter calls for actual visual content.

- Preserve the approved mock's major ingredients. Missing hero objects, missing world/product imagery, different section structure, downgraded CTA/nav treatment, or generic replacements for distinctive motifs are blocking defects unless the user accepted the change.
- Build semantically first: real headings, landmarks, labels, form associations, button/link semantics, accessible names, and state announcements where needed.
- Calibrate spacing, alignment, grid placement, and vertical rhythm deliberately. Do not accept default gaps, arbitrary margins, unbalanced whitespace, or accidental optical misalignment.
- Make typography intentional: chosen font loading strategy, clear hierarchy, readable measure, stable line breaks, tuned wrapping, and no overflow at mobile or large desktop sizes.
- Design realistic state coverage: default, hover where supported, focus-visible, active, disabled, loading, error, success, empty, overflow, long text, short text, and first-run states where relevant.
- Make interaction quality feel finished: keyboard paths, touch targets, feedback timing, scroll behavior, transitions between states, and no hover-only functionality.
- Use icons from the project's established icon set when available. If no set exists, choose a coherent library or use accessible text controls; do not mix unrelated icon styles.
- Optimize imagery and media: correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset` / `picture` for raster assets, and no project-referenced asset left outside the workspace.
- Make motion feel premium: use atmospheric blur, filter, mask, shadow, or reveal effects when they improve the experience; avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- Preserve maintainability: reusable local patterns, clear component boundaries, project conventions, no rasterized UI text, and no hard-coded one-off hacks when a better local pattern exists.
- Fit the technical context: production build passes, no obvious console errors, no avoidable layout shift, no needless dependency, and no broken asset path.

- **Realistic state coverage.** Default, hover, focus-visible, active, disabled, loading, error, success, empty, overflow, long/short text, first-run.
- **Finished interaction quality.** Keyboard paths, touch targets, feedback timing, scroll behavior, state transitions, no hover-only functionality.
- **Coherent icon set.** Use the project's established set; otherwise pick one library or use accessible text. Don't mix.
- **Respect the build pipeline.** Edit source files and run the project's build (`npm run build` or equivalent). Don't write to `build/` / `dist/` / `.next/` with `cat`, heredoc, or Bash redirects; that skips asset hashing, image optimization, code splitting, and CSS extraction, and produces output the dev server won't serve.
- **Verify image URLs before referencing them.** Use image-search MCP or web-fetch when available; guessed photo IDs ship as broken-image placeholders. Without verification, prefer fewer images you're confident about.
- **Optimized imagery and media.** Correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset`/`picture` for raster, no project-referenced asset left outside the workspace.
- **Premium motion.** Use atmospheric blur, filter, mask, shadow, reveal when they improve the experience. Avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- **Maintainable.** Reusable local patterns, clear component boundaries, project conventions. No rasterized UI text or one-off hacks when a local pattern exists.
- **Technically clean.** Production build passes, no console errors, no avoidable layout shift, no needless dependencies, no broken asset paths.
- **Ask when uncertain.** If a discovery materially changes the brief or approved direction, stop and ask. Don't guess.
## Step 6: Browser-Based Iteration
## Step 6: Iterate Visually
**This step is critical.** Do not stop after the first implementation pass.
Look at what you built like a designer would. Your eyes are whatever the harness gives you: a connected browser, a screenshotting tool, Playwright, or asking the user. Use them for responsive testing (mobile, tablet, desktop minimum) and general visual validation.
Open the result in a browser. In Codex, use browser-use or equivalent browser automation when available; otherwise use Playwright or ask the user for screenshots. Inspect screenshots, not just DOM or terminal output.
If your tool returns a file path, read the PNG back into the conversation. A screenshot you didn't read doesn't count.
### Required viewport pass
For long-form brand surfaces, inspect major sections individually. Thumbnails hide spacing, clipping, and cascade defects.
Check the experience at the viewports that matter for the brief. Default minimum:
After the first pass, write an honest critique against the brief, the approved mock's major ingredients (hero silhouette, motifs, imagery, nav/CTA, density), and impeccable's DON'Ts. Patch material defects and re-inspect. **Don't invent defects to demonstrate iteration.** A confident "first pass clean, shipping" beats a fake fix.
- Mobile narrow
- Tablet or small laptop
- Desktop wide
Actively check: responsive behavior (composes, not shrinks), every state (empty / error / loading / edge), craft details (spacing, alignment, hierarchy, contrast, motion timing, focus), performance basics. The exit bar: defensible in a high-end studio review.
For each viewport, capture or inspect the rendered state and look for visual defects: overlap, clipping, weak hierarchy, off-grid alignment, awkward whitespace, cramped controls, unreadable type, broken imagery, hover-only functionality, layout shift, and text overflow.
### Critique and fix loop
After the first browser pass, write a short critique for yourself and patch the implementation. Repeat browser inspection after fixes. Continue until no material issues remain against this checklist:
1. **Does it match the brief?** Compare the live result against every section of the design brief. Fix discrepancies.
2. **Does it match the approved mock?** Compare screenshots against the mock fidelity inventory: hero silhouette, major motifs, imagery, nav/CTA, section sequence, density, color/materials, and second-fold substance. Missing major ingredients are P0 defects.
3. **Does it pass the AI slop test?** If someone saw this and said "AI made this," would they believe it immediately? If yes, it needs more design intention.
4. **Check against impeccable's DON'T guidelines.** Fix any anti-pattern violations.
5. **Check every state.** Navigate through empty, error, loading, and edge case states. Each one should feel intentional, not like an afterthought.
6. **Check responsive behavior.** The design should adapt compositionally, not merely shrink.
7. **Check craft details.** Spacing consistency, optical alignment, type hierarchy, color contrast, image quality, icon coherence, interactive feedback, motion timing, and focus treatment.
8. **Check performance basics.** No obviously oversized images, avoidable layout thrash, blocking animations, or heavy assets without a reason.
The exit bar is not "it works." It is: the rendered result looks intentional at all checked viewports, all expected states are handled, no placeholders remain unless explicitly accepted, and the implementation quality would be defensible in a high-end studio review.

2. **Move the CSS rules** into the project's real stylesheet. Which stylesheet depends on the project (e.g. `public/css/workflow.css` for this repo, or the component's co-located CSS file for a Vite/Next project; pick whichever already owns styling for the surrounding element).

3. **Bake in parameter values while rewriting selectors.** For `@scope ([data-impeccable-variant="N"])` wrappers: retarget to real, semantic classes on the accepted HTML (`.why-visual--v2 .v2-label { … }`). For `:scope[data-p-<id>="VALUE"]` selectors: keep only the branch matching the chosen value from the param-values comment; drop the others (they're dead after accept). For `var(--p-<id>, DEFAULT)` in the CSS: either substitute the literal value, or if the param is still useful as a knob going forward, leave the var and update its initial declaration to the chosen value.
4. **Unwrap the accepted content.** Delete the `<div data-impeccable-variant="N" style="display: contents">` that wraps it. Drop `data-impeccable-params` and any `data-p-*` attributes from it; those are live-mode plumbing, not source.
5. **Delete the inline `<style>` block, the `<!-- impeccable-param-values -->` comment if present, and both `<!-- impeccable-carbonize-start/end -->` markers.** Also drop any `@scope` rules for variants other than the accepted one; those are dead code now.

After the interview and any required probes, present a brief and **end your response**. The user must confirm before any implementation runs. Do not present a brief and then continue to code in the same response, even if the brief feels obvious to you. The user's confirmation is the gate.
**Choose the brief shape based on how clear the answers are:**
- **Compact form (3-5 bullets)** when discovery was crisp and the original prompt + PRODUCT.md already pinned scope, content, and direction. State what you're building, the visual lane, and end with one or two specific questions or a clear "confirm or override?" prompt. This is the default for typical craft requests with a clear prompt.

Don't pad a clear brief into a long one to look thorough. A 70-line brief restating answers the user just gave is noise, not rigor. Equally, don't skip the confirmation pause to look efficient: the pause is the point.

1. Load context (PRODUCT.md / DESIGN.md) via the loader script.
2. Identify the register and load the matching register reference (brand.md or product.md).
3. **If the user invoked a sub-command (e.g. `craft`, `shape`, `audit`), load its reference file too.** This is non-negotiable: `craft` without `craft.md` loaded means you'll skip the shape-and-confirm step the user expects.
Codex-style agents must state this before editing files:
```text
IMPECCABLE_PREFLIGHT: context=pass product=pass command_reference=pass shape=pass|not_required image_gate=pass|skipped:<reason> mutation=open
```
For `/impeccable craft`, `shape=pass` is only valid after a separate user response approving the shape design brief, or when the user provided an already-confirmed brief in the request. Do not mark `shape=pass` after writing PRODUCT.md, summarizing assumptions, or drafting an unconfirmed brief yourself.
Other harnesses should follow the same checklist when they can expose this state.

# Craft Flow
Build a feature with impeccable UX and UI quality through a structured process: shape the design, land the visual direction, build real production code, then inspect and improve in-browser until the result meets a high-end studio bar.
Build a feature with impeccable UX and UI quality: shape the design, land the visual direction, build real production code, inspect and improve in-browser until it meets a high-end studio bar.
## Build Gate
Before writing code, you need: PRODUCT.md loaded, register identified and the matching reference loaded, and a confirmed design direction for this task (either from `shape` or supplied by the user). PRODUCT.md is project context, not a task-specific brief.
Craft cannot build until all of these are true:
Treat any approved visual direction (generated mock or stated reference) as a concrete contract for composition, hierarchy, density, atmosphere, signature motifs, and distinctive visual moves. Don't let mocks replace structure, copy, accessibility, or state design. But if the live result lacks the approved direction's major ingredients, the implementation is wrong.
1. PRODUCT context is valid and current.
2. The shape design brief is explicitly confirmed by the user for this task, unless the user already provided a confirmed brief.
3. Implementation references from the brief are loaded.
4. The shape visual probe decision is recorded: generated, skipped with reason, or already resolved.
5. The north-star mock decision is recorded: generated, skipped with reason, or not applicable.
## Step 0: Project Foundation
PRODUCT.md and `teach` answers do **not** satisfy the shape gate. They are project context only. A compact self-authored brief does not satisfy the shape gate either. `shape=pass` requires a separate user response approving the shape brief or an already-confirmed brief supplied by the user.
Before shape, before code: figure out what kind of project you're working in.
Invalid image-skip reasons include: "the final implementation will be semantic HTML/CSS/SVG", "the diagram should stay editable", "a raster mock would not be used directly", or "the product is fictional." Generated probes and mocks are direction artifacts; they are not implementation assets.
Look at the working directory. Run `ls`. Check for:
## Craft Contract
- An existing framework: `astro.config.mjs/ts`, `next.config.js/ts`, `nuxt.config.ts`, `svelte.config.js`, `vite.config.js/ts`, `package.json` with framework deps, `Cargo.toml` + Leptos/Yew, `Gemfile` + Rails. **If found, use it.** Do not start a parallel build, do not introduce a second framework, do not write to `dist/` or `build/` directly. Whatever pipeline the project has, respect it.
- An existing component library or design system: `src/components/`, `app/components/`, a `tokens.css` / `theme.ts`, an `astro.config` `integrations`. Read what's there before adding to it.
- An existing icon set: `lucide-react`, `@phosphor-icons/react`, `@iconify/*`, hand-rolled SVG sprites in `assets/icons/`. **Use what's already in the project**; don't introduce a second set.
Craft is not a first pass. It is a loop with these required artifacts:
If the directory is empty (greenfield), don't pick a framework silently. Ask the user via the AskUserQuestion tool, with sensible defaults framed by the brief:
1. Confirmed design brief from `shape`.
2. Approved visual direction, from generated probes / mocks when image generation is available.
3. Mock fidelity inventory: the visible ingredients from the approved direction that must survive into code.
4. Semantic, functional implementation using the project's real stack and conventions.
5. Browser evidence across relevant viewports.
6. At least one critique-and-fix pass after the first browser inspection, unless the first pass has no material defects.
```text
What should this be built on?
- Astro (default for content-led brand sites, landing pages, marketing surfaces)
- SvelteKit / Next.js / Nuxt (when the brief implies an app surface or significant interactivity)
- Single index.html (one-shot demo, prototype, or a deliberately framework-free experiment)
```
Do not let generated mockups replace interface structure, copy, accessibility, responsive behavior, or state design. But do treat the approved mock as a concrete visual contract for composition, hierarchy, density, atmosphere, signature motifs, image needs, and distinctive visual moves. "North star" means "preserve the important visible ingredients in semantic code," not "use it as loose mood."
Default: Astro for brand briefs, the project's existing framework for product briefs. Ask once; don't re-ask mid-task.
## Step 1: Shape the Design
Run /impeccable shape, passing along whatever feature description the user provided.
Run /impeccable shape, passing along whatever feature description the user provided. Shape is **required** for craft; it is what produces a confirmed direction.
Wait for the design brief to be fully confirmed by the user before proceeding. The brief is your blueprint, and every implementation decision should trace back to it.
Present the shape output and stop. Wait for the user to confirm, override, or course-correct before writing code.
If this craft run resumed after `teach` created PRODUCT.md, run shape now. Do not treat the teach interview, PRODUCT.md, or a summary of project context as a substitute for shape. Shape is task-specific and must cover scope, content/states, visual direction, constraints, anti-goals, probes when applicable, and explicit brief confirmation.
If the user already supplied a confirmed brief or ran shape separately, use it and skip this step.
If the user has already run /impeccable shape and has a confirmed design brief, skip this step and use the existing brief.
When the original prompt + PRODUCT.md already answer scope, content, and visual direction with no real ambiguity, the shape output can be **compact** (3-5 bullets stating what you're building and the visual lane, ending with one or two specific questions or "confirm or override"). The full 10-section structured brief is reserved for genuinely ambiguous, multi-screen, or stakeholder-heavy tasks.

Before implementation, generate high-fidelity visual comps when all of these are true:
Generate high-fidelity visual comps before implementation when all three are true:

When those conditions are met, this step is mandatory for **both brand and product work** in Codex and any harness with built-in image generation. Use native image generation; in Codex, use the built-in `image_gen` tool via the imagegen skill. If image generation is unavailable, do not ask the user to install APIs or tooling. State in one line that the image step is skipped because the harness lacks native image generation, then proceed.
Do not skip this step because the eventual UI should be semantic, editable, code-native, responsive, or accessible. Those are implementation requirements, not reasons to avoid visual exploration.
### Purpose
Use the mock step to find a stronger visual lane than code-first generation would reliably discover on its own. The brief remains authoritative on user, purpose, content, constraints, states, and anti-goals. The mock clarifies composition, hierarchy, density, typography, and visual tone.
When met, this step is mandatory for both brand and product work. If image generation isn't available, skip silently. "The eventual UI is semantic/code-native/accessible" is not a reason to skip; those are implementation requirements, not exploration ones.

Inventory the approved mock's major visible ingredients:
- Hero silhouette and dominant composition.
- Signature motifs: planets, devices, portraits, charts, route lines, insets, badges, or other memorable objects.

- Image-native content the concept depends on.

Use the native asset producer (`impeccable_asset_producer` in Codex, `impeccable-asset-producer` in Claude Code) to create clean assets from the hi-fi mock and crops. If you do not have explicit permission to use agents, stop and ask:
- stickers
- badges
- seals
- tickets
- graphic labels
- textures
- abstract objects
- decorative marks
- non-semantic scene elements
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
For travel, editorial, portfolio, venue, product showcase, entertainment, education, or any other image-led brand surface, visual assets are usually core content, not decoration. Do not ship abstract CSS panels where the approved mock or subject matter calls for real imagery, generated plates, illustrations, maps, product/object renders, or destination scenes.
Do not skip asset production or silently do it inline. Inline asset production is allowed only if the user declines subagents, the harness cannot spawn the authorized agent, or the user explicitly asks for single-thread mode.
Do **not** export assets for core UI text, navigation, body copy, or any structure that should stay semantic and editable in code.
Pass the approved mock, crop/contact-sheet paths, output directory, dimensions/formats, transparency needs, constraints, and avoid list to the asset producer. Attach image generation capability to the spawned agent when the harness supports it; do not load image-generation reference material into the parent thread first.
Usually **1 to 5** extracted assets is enough. If the design can be built cleanly in HTML/CSS/SVG, prefer that over raster assets. If the mock contains major visual content that cannot be built credibly in code, asset extraction is not optional.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; use real/generated/stock imagery when the mock or subject matter calls for actual visual content.

### Production bar
- Use real or realistic content. Remove placeholder copy, placeholder images, dead links, fake controls, and unused scaffold before presenting.
- Preserve the approved mock's major ingredients. Missing hero objects, missing world/product imagery, different section structure, downgraded CTA/nav treatment, or generic replacements for distinctive motifs are blocking defects unless the user accepted the change.
- Build semantically first: real headings, landmarks, labels, form associations, button/link semantics, accessible names, and state announcements where needed.
- Calibrate spacing, alignment, grid placement, and vertical rhythm deliberately. Do not accept default gaps, arbitrary margins, unbalanced whitespace, or accidental optical misalignment.
- Make typography intentional: chosen font loading strategy, clear hierarchy, readable measure, stable line breaks, tuned wrapping, and no overflow at mobile or large desktop sizes.
- Design realistic state coverage: default, hover where supported, focus-visible, active, disabled, loading, error, success, empty, overflow, long text, short text, and first-run states where relevant.
- Make interaction quality feel finished: keyboard paths, touch targets, feedback timing, scroll behavior, transitions between states, and no hover-only functionality.
- Use icons from the project's established icon set when available. If no set exists, choose a coherent library or use accessible text controls; do not mix unrelated icon styles.
- Optimize imagery and media: correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset` / `picture` for raster assets, and no project-referenced asset left outside the workspace.
- Make motion feel premium: use atmospheric blur, filter, mask, shadow, or reveal effects when they improve the experience; avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- Preserve maintainability: reusable local patterns, clear component boundaries, project conventions, no rasterized UI text, and no hard-coded one-off hacks when a better local pattern exists.
- Fit the technical context: production build passes, no obvious console errors, no avoidable layout shift, no needless dependency, and no broken asset path.
- If you discover a design question that materially changes the brief or approved direction, stop and ask rather than guessing.

- **Finished interaction quality.** Keyboard paths, touch targets, feedback timing, scroll behavior, state transitions, no hover-only functionality.
- **Coherent icon set.** Use the project's established set; otherwise pick one library or use accessible text. Don't mix.
- **Respect the build pipeline.** Edit source files and run the project's build (`npm run build` or equivalent). Don't write to `build/` / `dist/` / `.next/` with `cat`, heredoc, or Bash redirects; that skips asset hashing, image optimization, code splitting, and CSS extraction, and produces output the dev server won't serve.
- **Verify image URLs before referencing them.** Use image-search MCP or web-fetch when available; guessed photo IDs ship as broken-image placeholders. Without verification, prefer fewer images you're confident about.
- **Optimized imagery and media.** Correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset`/`picture` for raster, no project-referenced asset left outside the workspace.
- **Premium motion.** Use atmospheric blur, filter, mask, shadow, reveal when they improve the experience. Avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- **Maintainable.** Reusable local patterns, clear component boundaries, project conventions. No rasterized UI text or one-off hacks when a local pattern exists.
- **Technically clean.** Production build passes, no console errors, no avoidable layout shift, no needless dependencies, no broken asset paths.
- **Ask when uncertain.** If a discovery materially changes the brief or approved direction, stop and ask. Don't guess.
## Step 6: Browser-Based Iteration
## Step 6: Iterate Visually
**This step is critical.** Do not stop after the first implementation pass.
Look at what you built like a designer would. Your eyes are whatever the harness gives you: a connected browser, a screenshotting tool, Playwright, or asking the user. Use them for responsive testing (mobile, tablet, desktop minimum) and general visual validation.
Open the result in a browser. In Codex, use browser-use or equivalent browser automation when available; otherwise use Playwright or ask the user for screenshots. Inspect screenshots, not just DOM or terminal output.
If your tool returns a file path, read the PNG back into the conversation. A screenshot you didn't read doesn't count.
### Required viewport pass
For long-form brand surfaces, inspect major sections individually. Thumbnails hide spacing, clipping, and cascade defects.
Check the experience at the viewports that matter for the brief. Default minimum:
After the first pass, write an honest critique against the brief, the approved mock's major ingredients (hero silhouette, motifs, imagery, nav/CTA, density), and impeccable's DON'Ts. Patch material defects and re-inspect. **Don't invent defects to demonstrate iteration.** A confident "first pass clean, shipping" beats a fake fix.
- Mobile narrow
- Tablet or small laptop
- Desktop wide
Actively check: responsive behavior (composes, not shrinks), every state (empty / error / loading / edge), craft details (spacing, alignment, hierarchy, contrast, motion timing, focus), performance basics. The exit bar: defensible in a high-end studio review.
For each viewport, capture or inspect the rendered state and look for visual defects: overlap, clipping, weak hierarchy, off-grid alignment, awkward whitespace, cramped controls, unreadable type, broken imagery, hover-only functionality, layout shift, and text overflow.
### Critique and fix loop
After the first browser pass, write a short critique for yourself and patch the implementation. Repeat browser inspection after fixes. Continue until no material issues remain against this checklist:
1. **Does it match the brief?** Compare the live result against every section of the design brief. Fix discrepancies.
2. **Does it match the approved mock?** Compare screenshots against the mock fidelity inventory: hero silhouette, major motifs, imagery, nav/CTA, section sequence, density, color/materials, and second-fold substance. Missing major ingredients are P0 defects.
3. **Does it pass the AI slop test?** If someone saw this and said "AI made this," would they believe it immediately? If yes, it needs more design intention.
4. **Check against impeccable's DON'T guidelines.** Fix any anti-pattern violations.
5. **Check every state.** Navigate through empty, error, loading, and edge case states. Each one should feel intentional, not like an afterthought.
6. **Check responsive behavior.** The design should adapt compositionally, not merely shrink.
7. **Check craft details.** Spacing consistency, optical alignment, type hierarchy, color contrast, image quality, icon coherence, interactive feedback, motion timing, and focus treatment.
8. **Check performance basics.** No obviously oversized images, avoidable layout thrash, blocking animations, or heavy assets without a reason.
The exit bar is not "it works." It is: the rendered result looks intentional at all checked viewports, all expected states are handled, no placeholders remain unless explicitly accepted, and the implementation quality would be defensible in a high-end studio review.

- **Compact form (3-5 bullets)** when discovery was crisp and the original prompt + PRODUCT.md already pinned scope, content, and direction. State what you're building, the visual lane, and end with one or two specific questions or a clear "confirm or override?" prompt. This is the default for typical craft requests with a clear prompt.

# Impeccable Asset Producer
You are the asset production agent for Impeccable craft.
Your job is production cleanup, not new art direction. Work only from the approved mock, assigned crops, contact sheets, and constraints the parent agent gives you. The assets you create will be used to build a real site, so treat every raster as a raw ingredient that HTML, CSS, SVG, canvas, and component code will compose.
## Core Rule
Do not redesign. Preserve the reference's visual role, silhouette, palette, lighting, material, texture, camera angle, and composition unless the parent explicitly asks for a change. Preserve perspective only when it belongs to the object or scene itself; if CSS should create the card transform, shadow, rounded clipping, border, or layout, remove that presentation chrome from the raster.
## Input Contract
Expect:
- Approved mock path or screenshot reference.
- Crop paths or a contact sheet with crop ids.
- Output directory.
- Required dimensions, format, transparency needs, and avoid list.
- Notes on what should remain semantic HTML/CSS/SVG instead of raster.
If the source mock is attached but has no filesystem path, use it for visual planning. Ask for a path only before cropping or writing assets.
Use defaults unless contradicted:
- `.webp` for opaque photos, backgrounds, and textures.
- `.png` for transparent cutouts, seals, tickets, and illustrations.
- Target production size or at least 2x display size when dimensions are known. Do not use small full-page mock crop size as the default shipping size.
- Remove UI text, navigation, buttons, labels, and body copy by default.
- Keep physical marks only when the parent says they are part of the asset.
- Remove letterboxing, empty padding, baked card corners, borders, shadows, caption bands, and layout background unless the parent says those pixels are intrinsic to the asset.
- Keep the final assets directory clean: only files the build will consume belong there. Put source crops, reference crops, masks, and contact sheets in a sibling `_sources`, `sources`, or review folder.
Ask blockers once, globally. Missing source path/crops or output directory blocks production. Exact dimensions, compression targets, retina variants, and format preferences do not block; choose defaults and report them.
## Workflow
1. Inventory the full approved mock or every assigned crop.
2. Put each visual role in exactly one bucket:
- `produce`: needs generation, image editing, cleanup, cutout work, or a clean plate before it can ship.
- `direct`: can ship as a crop, format conversion, compression pass, or sourced replacement with no generative cleanup.
- `semantic`: build in HTML/CSS/SVG/canvas, no raster output.
3. Treat full-page mock crops as references, not production-resolution source assets. Put a role in `direct` only when the provided source is already a clean, sufficiently large source asset with no semantic text or presentation chrome.
4. Give the parent an execution order for the `produce` bucket.
5. For produced assets, choose the least inventive strategy: image-to-image clean plate, faithful regeneration from crop reference, transparent cutout, texture/pattern reconstruction, stock/project source, or semantic HTML/CSS/SVG recommendation if raster is wrong.
6. Treat every crop as binding reference. In Codex, use the imagegen skill and built-in `image_gen` path by default when generation or editing is needed.
7. Remove baked-in UI text, navigation, buttons, body copy, and mock chrome unless the text is part of the asset.
8. Think through the final DOM/CSS representation before generating. If CSS will own radius, clipping, shadows, borders, perspective, responsive cropping, captions, or card frames, do not bake those into the bitmap.
9. Save outputs non-destructively in the requested project directory.
10. Compare each output against its source crop. If a review/QA tool is available, run it before the final manifest, then retry each major/fatal finding once before finalizing.
Use `direct` only for provided source assets that can already ship after crop tightening, conversion, compression, or naming. Do not ship a small crop from the full-page mock as `direct` just because it looks close.
Use `texture/pattern extraction` only when the source region is already clean enough to sample as texture. If UI, cards, labels, headings, body copy, or footer chrome must be removed to make a reusable texture or background, classify it as crop-derived cleanup or clean-plate work.
Use `semantic` for dashboards, charts, controls, screenshots of whole UI sections, data widgets, card chrome, app frames, icon toolbars, logos, wordmarks, and anything the final implementation can render crisply in HTML/CSS/SVG/canvas. Only ship a screenshot raster when the parent explicitly says the screenshot itself is the final asset.
Semantic does not mean ignored. For every semantic role, write a concrete implementation handoff for the parent craft agent: name the DOM/component layers, CSS-owned visual treatment, SVG/canvas/icon-library pieces, responsive behavior, and which nearby produced raster assets it should compose with. For logos and icons, prefer inline SVG/vector or icon-library implementation unless the parent provides a production logo raster.
For transparency, prefer true alpha output when the tool supports it. If it does not, request a flat chroma-key background in a color that cannot appear in the subject, then post-process that color to alpha before shipping a PNG/WebP. Do not ship the keyed background as the final asset.
## Prompt Pattern
Use this shape for image-to-image work:
```text
Use the provided crop as the approved visual reference.
Recreate the same asset as a clean reusable production image at the target component aspect ratio and at least 2x display resolution.
Preserve silhouette, object/scene perspective, camera angle, palette, lighting, material, texture, and visual role.
Remove baked-in UI copy, navigation, buttons, labels, body text, watermarks, and mock chrome unless explicitly part of the asset.
Remove letterboxing, padding, card borders, rounded clipping, CSS shadows, perspective transforms, caption bands, and layout backgrounds that the implementation should create in code.
Do not add new objects. Do not change the concept. Do not redesign the composition.
```
For transparent cutouts, use the imagegen skill's built-in-first chroma-key workflow unless the parent explicitly authorizes a true native transparency fallback.
## Output Contract
Return a complete manifest, grouped by `produce`, `direct`, and `semantic`. For each asset include: `id`, `source_crop`, `output_path` when applicable, `strategy`, `prompt_used` when applicable, `dimensions`, `format`, `transparency`, `deviations`, and `qa_status`.
For each semantic row include `id`, `implementation`, `notes`, and `qa_status`. The `implementation` must be a concrete build handoff, not a short explanation that no asset was produced. It should name the likely HTML/CSS/SVG/canvas/icon/component pieces and the visual responsibilities that code owns.
`qa_status` must be `accepted`, `needs_parent_review`, or `blocked`. Use `accepted` only after visual comparison passes. Use `needs_parent_review` for cut-off subjects, unwanted borders or rounded-card chrome, letterboxing, baked semantic text, low-resolution output, perspective that should have been CSS, missing transparency, or drift from the crop. Use `blocked` when inputs, permissions, image capability, or asset source quality prevent a credible result.
End with `execution_order`, `blockers`, and `assumptions` sections. Keep blockers global and minimal. Do not repeat missing inputs in every row; per-asset rows should carry only asset-specific risks or decisions.
Do not modify implementation code. Do not edit the approved mock. Do not produce final page copy. The parent craft agent owns implementation and final mock fidelity.

3. **If the user invoked a sub-command (e.g. `craft`, `shape`, `audit`), load its reference file too.** This is non-negotiable: `craft` without `craft.md` loaded means you'll skip the shape-and-confirm step the user expects.
Codex-style agents must state this before editing files:
```text

For `/impeccable craft`, `shape=pass` is only valid after a separate user response approving the shape design brief, or when the user provided an already-confirmed brief in the request. Do not mark `shape=pass` after writing PRODUCT.md, summarizing assumptions, or drafting an unconfirmed brief yourself.
Other harnesses should follow the same checklist when they can expose this state.

# Craft Flow
Build a feature with impeccable UX and UI quality through a structured process: shape the design, land the visual direction, build real production code, then inspect and improve in-browser until the result meets a high-end studio bar.
Build a feature with impeccable UX and UI quality: shape the design, land the visual direction, build real production code, inspect and improve in-browser until it meets a high-end studio bar.
## Build Gate
Before writing code, you need: PRODUCT.md loaded, register identified and the matching reference loaded, and a confirmed design direction for this task (either from `shape` or supplied by the user). PRODUCT.md is project context, not a task-specific brief.
Craft cannot build until all of these are true:
Treat any approved visual direction (generated mock or stated reference) as a concrete contract for composition, hierarchy, density, atmosphere, signature motifs, and distinctive visual moves. Don't let mocks replace structure, copy, accessibility, or state design. But if the live result lacks the approved direction's major ingredients, the implementation is wrong.
1. PRODUCT context is valid and current.
2. The shape design brief is explicitly confirmed by the user for this task, unless the user already provided a confirmed brief.
3. Implementation references from the brief are loaded.
4. The shape visual probe decision is recorded: generated, skipped with reason, or already resolved.
5. The north-star mock decision is recorded: generated, skipped with reason, or not applicable.
## Step 0: Project Foundation
PRODUCT.md and `teach` answers do **not** satisfy the shape gate. They are project context only. A compact self-authored brief does not satisfy the shape gate either. `shape=pass` requires a separate user response approving the shape brief or an already-confirmed brief supplied by the user.
Before shape, before code: figure out what kind of project you're working in.
Invalid image-skip reasons include: "the final implementation will be semantic HTML/CSS/SVG", "the diagram should stay editable", "a raster mock would not be used directly", or "the product is fictional." Generated probes and mocks are direction artifacts; they are not implementation assets.
Look at the working directory. Run `ls`. Check for:
## Craft Contract
- An existing framework: `astro.config.mjs/ts`, `next.config.js/ts`, `nuxt.config.ts`, `svelte.config.js`, `vite.config.js/ts`, `package.json` with framework deps, `Cargo.toml` + Leptos/Yew, `Gemfile` + Rails. **If found, use it.** Do not start a parallel build, do not introduce a second framework, do not write to `dist/` or `build/` directly. Whatever pipeline the project has, respect it.
- An existing component library or design system: `src/components/`, `app/components/`, a `tokens.css` / `theme.ts`, an `astro.config` `integrations`. Read what's there before adding to it.
- An existing icon set: `lucide-react`, `@phosphor-icons/react`, `@iconify/*`, hand-rolled SVG sprites in `assets/icons/`. **Use what's already in the project**; don't introduce a second set.
Craft is not a first pass. It is a loop with these required artifacts:
If the directory is empty (greenfield), don't pick a framework silently. Ask the user via the AskUserQuestion tool, with sensible defaults framed by the brief:
1. Confirmed design brief from `shape`.
2. Approved visual direction, from generated probes / mocks when image generation is available.
3. Mock fidelity inventory: the visible ingredients from the approved direction that must survive into code.
4. Semantic, functional implementation using the project's real stack and conventions.
5. Browser evidence across relevant viewports.
6. At least one critique-and-fix pass after the first browser inspection, unless the first pass has no material defects.
```text
What should this be built on?
- Astro (default for content-led brand sites, landing pages, marketing surfaces)
- SvelteKit / Next.js / Nuxt (when the brief implies an app surface or significant interactivity)
- Single index.html (one-shot demo, prototype, or a deliberately framework-free experiment)
```
Do not let generated mockups replace interface structure, copy, accessibility, responsive behavior, or state design. But do treat the approved mock as a concrete visual contract for composition, hierarchy, density, atmosphere, signature motifs, image needs, and distinctive visual moves. "North star" means "preserve the important visible ingredients in semantic code," not "use it as loose mood."
Default: Astro for brand briefs, the project's existing framework for product briefs. Ask once; don't re-ask mid-task.
## Step 1: Shape the Design
Run /impeccable shape, passing along whatever feature description the user provided.
Run /impeccable shape, passing along whatever feature description the user provided. Shape is **required** for craft; it is what produces a confirmed direction.
Wait for the design brief to be fully confirmed by the user before proceeding. The brief is your blueprint, and every implementation decision should trace back to it.
Present the shape output and stop. Wait for the user to confirm, override, or course-correct before writing code.
If this craft run resumed after `teach` created PRODUCT.md, run shape now. Do not treat the teach interview, PRODUCT.md, or a summary of project context as a substitute for shape. Shape is task-specific and must cover scope, content/states, visual direction, constraints, anti-goals, probes when applicable, and explicit brief confirmation.
If the user already supplied a confirmed brief or ran shape separately, use it and skip this step.
If the user has already run /impeccable shape and has a confirmed design brief, skip this step and use the existing brief.
When the original prompt + PRODUCT.md already answer scope, content, and visual direction with no real ambiguity, the shape output can be **compact** (3-5 bullets stating what you're building and the visual lane, ending with one or two specific questions or "confirm or override"). The full 10-section structured brief is reserved for genuinely ambiguous, multi-screen, or stakeholder-heavy tasks. Don't pad a clear brief into a long one to look thorough; equally, don't skip the pause to look efficient.

## Step 3: Land the Visual Direction (Capability-Gated)
Before implementation, generate high-fidelity visual comps when all of these are true:
Generate high-fidelity visual comps before implementation when all three are true:
- The work is **net-new** or visually open-ended enough that composition exploration will improve the build.
- The brief's scope is **mid-fi, high-fi, or production-ready**.
- The current harness has **built-in image generation capability** (for example, Codex with a native image tool). Do **not** ask the user to set up external APIs, shell scripts, or one-off tooling just to do this.
- The work is net-new or visually open-ended enough that composition exploration will improve the build.
- The brief's scope is mid-fi, high-fi, or production-ready.
- The harness gives you native image generation (Codex's `image_gen`, an equivalent MCP tool). Don't ask the user to set up external APIs.
When those conditions are met, this step is mandatory for **both brand and product work** in Codex and any harness with built-in image generation. Use native image generation; in Codex, use the built-in `image_gen` tool via the imagegen skill. If image generation is unavailable, do not ask the user to install APIs or tooling. State in one line that the image step is skipped because the harness lacks native image generation, then proceed.
Do not skip this step because the eventual UI should be semantic, editable, code-native, responsive, or accessible. Those are implementation requirements, not reasons to avoid visual exploration.
### Purpose
Use the mock step to find a stronger visual lane than code-first generation would reliably discover on its own. The brief remains authoritative on user, purpose, content, constraints, states, and anti-goals. The mock clarifies composition, hierarchy, density, typography, and visual tone.
When met, this step is mandatory for both brand and product work. If image generation isn't available, skip silently. "The eventual UI is semantic/code-native/accessible" is not a reason to skip; those are implementation requirements, not exploration ones.
### What to generate
Generate **1 to 3** high-fidelity north-star comps based on the confirmed brief. If shape already produced direction probes, use those results as input and generate a more resolved mock from the winning lane, not another unrelated exploration.
Generate **1 to 3** high-fidelity north-star comps from the confirmed brief. If shape already produced direction probes, resolve the winning lane further, not an unrelated exploration. Comps must differ in primary visual direction, not just color.

- For product work, still push hierarchy, topology, density, and tone, but keep the comps grounded in realistic product structure and states.
- For landing pages and long-form brand surfaces, show enough of the next section or second fold to establish the system beyond the hero.

### Mock fidelity inventory
Before building, inventory the approved mock's major visible ingredients:
Inventory the approved mock's major visible ingredients:
- Hero silhouette and dominant composition.
- Signature motifs: planets, devices, portraits, charts, route lines, insets, badges, or other memorable objects.
- Nav and primary CTA treatment.
- Section sequence visible in the mock, especially the second fold.
- Image-native content the concept depends on.
- Typography, density, color/material treatment, and motion cues.

For each ingredient, decide how it will be implemented: semantic HTML/CSS/SVG, generated asset, sourced project asset, icon library, canvas/WebGL, or an explicitly accepted omission. Do not substitute a different hero composition or new visual driver after approval unless the user approves the change.
For each, decide implementation: semantic HTML/CSS/SVG, generated asset, sourced asset, icon library, canvas/WebGL, or accepted omission. Don't substitute a different hero composition or visual driver post-approval without user sign-off.
Treat the mock as a **north star**, not a screenshot to trace. Do **not** rasterize core UI text or let the mock override the confirmed brief. But if the live result lacks the mock's major visible ingredients, the implementation is wrong.

Treat the mock as a north star, not a screenshot to trace. Don't rasterize core UI text. But if the live result lacks the mock's major ingredients, the implementation is wrong.
## Step 4: Asset Extraction (Need-Gated)
If the chosen direction includes image-native visual ingredients that would materially improve the implementation, generate them as separate assets before building.
If the approved direction needs raster assets, create them before building. Do not replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy.
Good candidates:
Use the native asset producer (`impeccable_asset_producer` in Codex, `impeccable-asset-producer` in Claude Code) to create clean assets from the hi-fi mock and crops. If you do not have explicit permission to use agents, stop and ask:
- stickers
- badges
- seals
- tickets
- graphic labels
- textures
- abstract objects
- decorative marks
- non-semantic scene elements
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
For travel, editorial, portfolio, venue, product showcase, entertainment, education, or any other image-led brand surface, visual assets are usually core content, not decoration. Do not ship abstract CSS panels where the approved mock or subject matter calls for real imagery, generated plates, illustrations, maps, product/object renders, or destination scenes.
Do not skip asset production or silently do it inline. Inline asset production is allowed only if the user declines subagents, the harness cannot spawn the authorized agent, or the user explicitly asks for single-thread mode.
Do **not** export assets for core UI text, navigation, body copy, or any structure that should stay semantic and editable in code.
Pass the approved mock, crop/contact-sheet paths, output directory, dimensions/formats, transparency needs, constraints, and avoid list to the asset producer. Attach image generation capability to the spawned agent when the harness supports it; do not load image-generation reference material into the parent thread first.
Usually **1 to 5** extracted assets is enough. If the design can be built cleanly in HTML/CSS/SVG, prefer that over raster assets. If the mock contains major visual content that cannot be built credibly in code, asset extraction is not optional.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; use real/generated/stock imagery when the mock or subject matter calls for actual visual content.

- Build semantically first: real headings, landmarks, labels, form associations, button/link semantics, accessible names, and state announcements where needed.
- Calibrate spacing, alignment, grid placement, and vertical rhythm deliberately. Do not accept default gaps, arbitrary margins, unbalanced whitespace, or accidental optical misalignment.
- Make typography intentional: chosen font loading strategy, clear hierarchy, readable measure, stable line breaks, tuned wrapping, and no overflow at mobile or large desktop sizes.
- Design realistic state coverage: default, hover where supported, focus-visible, active, disabled, loading, error, success, empty, overflow, long text, short text, and first-run states where relevant.
- Make interaction quality feel finished: keyboard paths, touch targets, feedback timing, scroll behavior, transitions between states, and no hover-only functionality.
- Use icons from the project's established icon set when available. If no set exists, choose a coherent library or use accessible text controls; do not mix unrelated icon styles.
- Optimize imagery and media: correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset` / `picture` for raster assets, and no project-referenced asset left outside the workspace.
- Make motion feel premium: use atmospheric blur, filter, mask, shadow, or reveal effects when they improve the experience; avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- Preserve maintainability: reusable local patterns, clear component boundaries, project conventions, no rasterized UI text, and no hard-coded one-off hacks when a better local pattern exists.
- Fit the technical context: production build passes, no obvious console errors, no avoidable layout shift, no needless dependency, and no broken asset path.

## Step 6: Browser-Based Iteration
## Step 6: Iterate Visually
**This step is critical.** Do not stop after the first implementation pass.
Look at what you built like a designer would. Your eyes are whatever the harness gives you: a connected browser, a screenshotting tool, Playwright, or asking the user. Use them for responsive testing (mobile, tablet, desktop minimum) and general visual validation.
Open the result in a browser. In Codex, use browser-use or equivalent browser automation when available; otherwise use Playwright or ask the user for screenshots. Inspect screenshots, not just DOM or terminal output.
If your tool returns a file path, read the PNG back into the conversation. A screenshot you didn't read doesn't count.
### Required viewport pass
For long-form brand surfaces, inspect major sections individually. Thumbnails hide spacing, clipping, and cascade defects.
Check the experience at the viewports that matter for the brief. Default minimum:
After the first pass, write an honest critique against the brief, the approved mock's major ingredients (hero silhouette, motifs, imagery, nav/CTA, density), and impeccable's DON'Ts. Patch material defects and re-inspect. **Don't invent defects to demonstrate iteration.** A confident "first pass clean, shipping" beats a fake fix.
- Mobile narrow
- Tablet or small laptop
- Desktop wide
Actively check: responsive behavior (composes, not shrinks), every state (empty / error / loading / edge), craft details (spacing, alignment, hierarchy, contrast, motion timing, focus), performance basics. The exit bar: defensible in a high-end studio review.
For each viewport, capture or inspect the rendered state and look for visual defects: overlap, clipping, weak hierarchy, off-grid alignment, awkward whitespace, cramped controls, unreadable type, broken imagery, hover-only functionality, layout shift, and text overflow.
### Critique and fix loop
After the first browser pass, write a short critique for yourself and patch the implementation. Repeat browser inspection after fixes. Continue until no material issues remain against this checklist:
1. **Does it match the brief?** Compare the live result against every section of the design brief. Fix discrepancies.
2. **Does it match the approved mock?** Compare screenshots against the mock fidelity inventory: hero silhouette, major motifs, imagery, nav/CTA, section sequence, density, color/materials, and second-fold substance. Missing major ingredients are P0 defects.
3. **Does it pass the AI slop test?** If someone saw this and said "AI made this," would they believe it immediately? If yes, it needs more design intention.
4. **Check against impeccable's DON'T guidelines.** Fix any anti-pattern violations.
5. **Check every state.** Navigate through empty, error, loading, and edge case states. Each one should feel intentional, not like an afterthought.
6. **Check responsive behavior.** The design should adapt compositionally, not merely shrink.
7. **Check craft details.** Spacing consistency, optical alignment, type hierarchy, color contrast, image quality, icon coherence, interactive feedback, motion timing, and focus treatment.
8. **Check performance basics.** No obviously oversized images, avoidable layout thrash, blocking animations, or heavy assets without a reason.
The exit bar is not "it works." It is: the rendered result looks intentional at all checked viewports, all expected states are handled, no placeholders remain unless explicitly accepted, and the implementation quality would be defensible in a high-end studio review.

After the interview and any required probes, present a brief and **end your response**. The user must confirm before any implementation runs. Do not present a brief and then continue to code in the same response, even if the brief feels obvious to you. The user's confirmation is the gate.
**Choose the brief shape based on how clear the answers are:**
- **Compact form (3-5 bullets)** when discovery was crisp and the original prompt + PRODUCT.md already pinned scope, content, and direction. State what you're building, the visual lane, and end with one or two specific questions or a clear "confirm or override?" prompt. This is the default for typical craft requests with a clear prompt.
- **Full structured form (sections below)** when the task is genuinely ambiguous, multi-screen, or when the user asked for shape as a standalone step. Use this when the discipline of structure earns its weight.
Don't pad a clear brief into a long one to look thorough. A 70-line brief restating answers the user just gave is noise, not rigor. Equally, don't skip the confirmation pause to look efficient: the pause is the point.

| Context | The PRODUCT.md / DESIGN.md loader result is known from `node .gemini/skills/impeccable/scripts/load-context.mjs`. | Run the loader before continuing. |
| Product | PRODUCT.md exists and is not empty or placeholder (`[TODO]` markers, <200 chars). | Run `/impeccable teach`, refresh context, then resume. Never synthesize PRODUCT.md from the user's original prompt alone. |
| Command | The matching command reference is loaded when a sub-command is used. | Load the reference before continuing. |
| Craft | `/impeccable craft` has a user-confirmed shape brief for this task. `teach` / PRODUCT.md never counts as shape. | Run `/impeccable shape` and wait for explicit brief confirmation. |
| Image | Required visual probes / mocks are generated or skipped with a reason. | Resolve the image-generation gate in `shape.md` or `craft.md` before code. |
| Mutation | All active gates above pass. | Do not edit project files yet. |
1. Load context (PRODUCT.md / DESIGN.md) via the loader script.
2. Identify the register and load the matching register reference (brand.md or product.md).
3. **If the user invoked a sub-command (e.g. `craft`, `shape`, `audit`), load its reference file too.** This is non-negotiable: `craft` without `craft.md` loaded means you'll skip the shape-and-confirm step the user expects.
Codex-style agents must state this before editing files:
```text
IMPECCABLE_PREFLIGHT: context=pass product=pass command_reference=pass shape=pass|not_required image_gate=pass|skipped:<reason> mutation=open
```
For `/impeccable craft`, `shape=pass` is only valid after a separate user response approving the shape design brief, or when the user provided an already-confirmed brief in the request. Do not mark `shape=pass` after writing PRODUCT.md, summarizing assumptions, or drafting an unconfirmed brief yourself.
Other harnesses should follow the same checklist when they can expose this state.

# Craft Flow
Build a feature with impeccable UX and UI quality through a structured process: shape the design, land the visual direction, build real production code, then inspect and improve in-browser until the result meets a high-end studio bar.
Build a feature with impeccable UX and UI quality: shape the design, land the visual direction, build real production code, inspect and improve in-browser until it meets a high-end studio bar.
## Build Gate
Before writing code, you need: PRODUCT.md loaded, register identified and the matching reference loaded, and a confirmed design direction for this task (either from `shape` or supplied by the user). PRODUCT.md is project context, not a task-specific brief.
Craft cannot build until all of these are true:
Treat any approved visual direction (generated mock or stated reference) as a concrete contract for composition, hierarchy, density, atmosphere, signature motifs, and distinctive visual moves. Don't let mocks replace structure, copy, accessibility, or state design. But if the live result lacks the approved direction's major ingredients, the implementation is wrong.
1. PRODUCT context is valid and current.
2. The shape design brief is explicitly confirmed by the user for this task, unless the user already provided a confirmed brief.
3. Implementation references from the brief are loaded.
4. The shape visual probe decision is recorded: generated, skipped with reason, or already resolved.
5. The north-star mock decision is recorded: generated, skipped with reason, or not applicable.
## Step 0: Project Foundation
PRODUCT.md and `teach` answers do **not** satisfy the shape gate. They are project context only. A compact self-authored brief does not satisfy the shape gate either. `shape=pass` requires a separate user response approving the shape brief or an already-confirmed brief supplied by the user.
Before shape, before code: figure out what kind of project you're working in.
Invalid image-skip reasons include: "the final implementation will be semantic HTML/CSS/SVG", "the diagram should stay editable", "a raster mock would not be used directly", or "the product is fictional." Generated probes and mocks are direction artifacts; they are not implementation assets.
Look at the working directory. Run `ls`. Check for:
## Craft Contract
- An existing framework: `astro.config.mjs/ts`, `next.config.js/ts`, `nuxt.config.ts`, `svelte.config.js`, `vite.config.js/ts`, `package.json` with framework deps, `Cargo.toml` + Leptos/Yew, `Gemfile` + Rails. **If found, use it.** Do not start a parallel build, do not introduce a second framework, do not write to `dist/` or `build/` directly. Whatever pipeline the project has, respect it.
- An existing component library or design system: `src/components/`, `app/components/`, a `tokens.css` / `theme.ts`, an `astro.config` `integrations`. Read what's there before adding to it.
- An existing icon set: `lucide-react`, `@phosphor-icons/react`, `@iconify/*`, hand-rolled SVG sprites in `assets/icons/`. **Use what's already in the project**; don't introduce a second set.
Craft is not a first pass. It is a loop with these required artifacts:
If the directory is empty (greenfield), don't pick a framework silently. Ask the user via the AskUserQuestion tool, with sensible defaults framed by the brief:
1. Confirmed design brief from `shape`.
2. Approved visual direction, from generated probes / mocks when image generation is available.
3. Mock fidelity inventory: the visible ingredients from the approved direction that must survive into code.
4. Semantic, functional implementation using the project's real stack and conventions.
5. Browser evidence across relevant viewports.
6. At least one critique-and-fix pass after the first browser inspection, unless the first pass has no material defects.
```text
What should this be built on?
- Astro (default for content-led brand sites, landing pages, marketing surfaces)
- SvelteKit / Next.js / Nuxt (when the brief implies an app surface or significant interactivity)
- Single index.html (one-shot demo, prototype, or a deliberately framework-free experiment)
```
Do not let generated mockups replace interface structure, copy, accessibility, responsive behavior, or state design. But do treat the approved mock as a concrete visual contract for composition, hierarchy, density, atmosphere, signature motifs, image needs, and distinctive visual moves. "North star" means "preserve the important visible ingredients in semantic code," not "use it as loose mood."
Default: Astro for brand briefs, the project's existing framework for product briefs. Ask once; don't re-ask mid-task.
## Step 1: Shape the Design
Run /impeccable shape, passing along whatever feature description the user provided.
Run /impeccable shape, passing along whatever feature description the user provided. Shape is **required** for craft; it is what produces a confirmed direction.
Wait for the design brief to be fully confirmed by the user before proceeding. The brief is your blueprint, and every implementation decision should trace back to it.
Present the shape output and stop. Wait for the user to confirm, override, or course-correct before writing code.
If this craft run resumed after `teach` created PRODUCT.md, run shape now. Do not treat the teach interview, PRODUCT.md, or a summary of project context as a substitute for shape. Shape is task-specific and must cover scope, content/states, visual direction, constraints, anti-goals, probes when applicable, and explicit brief confirmation.
If the user already supplied a confirmed brief or ran shape separately, use it and skip this step.
If the user has already run /impeccable shape and has a confirmed design brief, skip this step and use the existing brief.
When the original prompt + PRODUCT.md already answer scope, content, and visual direction with no real ambiguity, the shape output can be **compact** (3-5 bullets stating what you're building and the visual lane, ending with one or two specific questions or "confirm or override"). The full 10-section structured brief is reserved for genuinely ambiguous, multi-screen, or stakeholder-heavy tasks.

Before implementation, generate high-fidelity visual comps when all of these are true:
Generate high-fidelity visual comps before implementation when all three are true:

State in one line that the image step is skipped because the harness lacks native image generation, then proceed.
Do not skip this step because the eventual UI should be semantic, editable, code-native, responsive, or accessible. Those are implementation requirements, not reasons to avoid visual exploration.
### Purpose
Use the mock step to find a stronger visual lane than code-first generation would reliably discover on its own. The brief remains authoritative on user, purpose, content, constraints, states, and anti-goals. The mock clarifies composition, hierarchy, density, typography, and visual tone.
When met, this step is mandatory for both brand and product work. If image generation isn't available, skip silently. "The eventual UI is semantic/code-native/accessible" is not a reason to skip; those are implementation requirements, not exploration ones.

Before building, inventory the approved mock's major visible ingredients:
Inventory the approved mock's major visible ingredients:
- Hero silhouette and dominant composition.
- Signature motifs: planets, devices, portraits, charts, route lines, insets, badges, or other memorable objects.
- Nav and primary CTA treatment.

- Image-native content the concept depends on.

For each ingredient, decide how it will be implemented: semantic HTML/CSS/SVG, generated asset, sourced project asset, icon library, canvas/WebGL, or an explicitly accepted omission. Do not substitute a different hero composition or new visual driver after approval unless the user approves the change.

Treat the mock as a north star, not a screenshot to trace. Don't rasterize core UI text. But if the live result lacks the mock's major ingredients, the implementation is wrong.
## Step 4: Asset Extraction (Need-Gated)
If the chosen direction includes image-native visual ingredients that would materially improve the implementation, generate them as separate assets before building.
If the approved direction needs raster assets, create them before building. Do not replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy.
Good candidates:
Use the native asset producer (`impeccable_asset_producer` in Codex, `impeccable-asset-producer` in Claude Code) to create clean assets from the hi-fi mock and crops. If you do not have explicit permission to use agents, stop and ask:
- stickers
- badges
- seals
- tickets
- graphic labels
- textures
- abstract objects
- decorative marks
- non-semantic scene elements
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
For travel, editorial, portfolio, venue, product showcase, entertainment, education, or any other image-led brand surface, visual assets are usually core content, not decoration. Do not ship abstract CSS panels where the approved mock or subject matter calls for real imagery, generated plates, illustrations, maps, product/object renders, or destination scenes.
Do not skip asset production or silently do it inline. Inline asset production is allowed only if the user declines subagents, the harness cannot spawn the authorized agent, or the user explicitly asks for single-thread mode.
Do **not** export assets for core UI text, navigation, body copy, or any structure that should stay semantic and editable in code.
Pass the approved mock, crop/contact-sheet paths, output directory, dimensions/formats, transparency needs, constraints, and avoid list to the asset producer. Attach image generation capability to the spawned agent when the harness supports it; do not load image-generation reference material into the parent thread first.
Usually **1 to 5** extracted assets is enough. If the design can be built cleanly in HTML/CSS/SVG, prefer that over raster assets. If the mock contains major visual content that cannot be built credibly in code, asset extraction is not optional.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; use real/generated/stock imagery when the mock or subject matter calls for actual visual content.

- Calibrate spacing, alignment, grid placement, and vertical rhythm deliberately. Do not accept default gaps, arbitrary margins, unbalanced whitespace, or accidental optical misalignment.
- Make typography intentional: chosen font loading strategy, clear hierarchy, readable measure, stable line breaks, tuned wrapping, and no overflow at mobile or large desktop sizes.
- Design realistic state coverage: default, hover where supported, focus-visible, active, disabled, loading, error, success, empty, overflow, long text, short text, and first-run states where relevant.
- Make interaction quality feel finished: keyboard paths, touch targets, feedback timing, scroll behavior, transitions between states, and no hover-only functionality.
- Use icons from the project's established icon set when available. If no set exists, choose a coherent library or use accessible text controls; do not mix unrelated icon styles.
- Optimize imagery and media: correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset` / `picture` for raster assets, and no project-referenced asset left outside the workspace.
- Make motion feel premium: use atmospheric blur, filter, mask, shadow, or reveal effects when they improve the experience; avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- Preserve maintainability: reusable local patterns, clear component boundaries, project conventions, no rasterized UI text, and no hard-coded one-off hacks when a better local pattern exists.
- Fit the technical context: production build passes, no obvious console errors, no avoidable layout shift, no needless dependency, and no broken asset path.
- If you discover a design question that materially changes the brief or approved direction, stop and ask rather than guessing.
- **Real content.** No placeholder copy, placeholder images, dead links, fake controls, or unused scaffold at presentation time.
- **Preserve the approved mock's major ingredients.** Missing hero objects, world/product imagery, section structure, CTA/nav treatment, or distinctive motifs are blocking defects unless the user accepted the change.
- **Semantic first.** Real headings, landmarks, labels, form associations, button/link semantics, accessible names, state announcements where needed.
- **Deliberate spacing and alignment.** No default gaps, arbitrary margins, unbalanced whitespace, or accidental optical misalignment.
- **Intentional typography.** Chosen loading strategy, clear hierarchy, readable measure, stable line breaks, no overflow at any width.
- **Realistic state coverage.** Default, hover, focus-visible, active, disabled, loading, error, success, empty, overflow, long/short text, first-run.
- **Finished interaction quality.** Keyboard paths, touch targets, feedback timing, scroll behavior, state transitions, no hover-only functionality.
- **Coherent icon set.** Use the project's established set; otherwise pick one library or use accessible text. Don't mix.
- **Respect the build pipeline.** Edit source files and run the project's build (`npm run build` or equivalent). Don't write to `build/` / `dist/` / `.next/` with `cat`, heredoc, or Bash redirects; that skips asset hashing, image optimization, code splitting, and CSS extraction, and produces output the dev server won't serve.
- **Verify image URLs before referencing them.** Use image-search MCP or web-fetch when available; guessed photo IDs ship as broken-image placeholders. Without verification, prefer fewer images you're confident about.
- **Optimized imagery and media.** Correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset`/`picture` for raster, no project-referenced asset left outside the workspace.
- **Premium motion.** Use atmospheric blur, filter, mask, shadow, reveal when they improve the experience. Avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- **Maintainable.** Reusable local patterns, clear component boundaries, project conventions. No rasterized UI text or one-off hacks when a local pattern exists.
- **Technically clean.** Production build passes, no console errors, no avoidable layout shift, no needless dependencies, no broken asset paths.
- **Ask when uncertain.** If a discovery materially changes the brief or approved direction, stop and ask. Don't guess.
## Step 6: Browser-Based Iteration
## Step 6: Iterate Visually
**This step is critical.** Do not stop after the first implementation pass.
Look at what you built like a designer would. Your eyes are whatever the harness gives you: a connected browser, a screenshotting tool, Playwright, or asking the user. Use them for responsive testing (mobile, tablet, desktop minimum) and general visual validation.
Open the result in a browser. In Codex, use browser-use or equivalent browser automation when available; otherwise use Playwright or ask the user for screenshots. Inspect screenshots, not just DOM or terminal output.
If your tool returns a file path, read the PNG back into the conversation. A screenshot you didn't read doesn't count.
### Required viewport pass
For long-form brand surfaces, inspect major sections individually. Thumbnails hide spacing, clipping, and cascade defects.
Check the experience at the viewports that matter for the brief. Default minimum:
After the first pass, write an honest critique against the brief, the approved mock's major ingredients (hero silhouette, motifs, imagery, nav/CTA, density), and impeccable's DON'Ts. Patch material defects and re-inspect. **Don't invent defects to demonstrate iteration.** A confident "first pass clean, shipping" beats a fake fix.
- Mobile narrow
- Tablet or small laptop
- Desktop wide
Actively check: responsive behavior (composes, not shrinks), every state (empty / error / loading / edge), craft details (spacing, alignment, hierarchy, contrast, motion timing, focus), performance basics. The exit bar: defensible in a high-end studio review.
For each viewport, capture or inspect the rendered state and look for visual defects: overlap, clipping, weak hierarchy, off-grid alignment, awkward whitespace, cramped controls, unreadable type, broken imagery, hover-only functionality, layout shift, and text overflow.
### Critique and fix loop
After the first browser pass, write a short critique for yourself and patch the implementation. Repeat browser inspection after fixes. Continue until no material issues remain against this checklist:
1. **Does it match the brief?** Compare the live result against every section of the design brief. Fix discrepancies.
2. **Does it match the approved mock?** Compare screenshots against the mock fidelity inventory: hero silhouette, major motifs, imagery, nav/CTA, section sequence, density, color/materials, and second-fold substance. Missing major ingredients are P0 defects.
3. **Does it pass the AI slop test?** If someone saw this and said "AI made this," would they believe it immediately? If yes, it needs more design intention.
4. **Check against impeccable's DON'T guidelines.** Fix any anti-pattern violations.
5. **Check every state.** Navigate through empty, error, loading, and edge case states. Each one should feel intentional, not like an afterthought.
6. **Check responsive behavior.** The design should adapt compositionally, not merely shrink.
7. **Check craft details.** Spacing consistency, optical alignment, type hierarchy, color contrast, image quality, icon coherence, interactive feedback, motion timing, and focus treatment.
8. **Check performance basics.** No obviously oversized images, avoidable layout thrash, blocking animations, or heavy assets without a reason.
The exit bar is not "it works." It is: the rendered result looks intentional at all checked viewports, all expected states are handled, no placeholders remain unless explicitly accepted, and the implementation quality would be defensible in a high-end studio review.

After the interview and any required probes, present a brief and **end your response**. The user must confirm before any implementation runs. Do not present a brief and then continue to code in the same response, even if the brief feels obvious to you. The user's confirmation is the gate.
**Choose the brief shape based on how clear the answers are:**
- **Compact form (3-5 bullets)** when discovery was crisp and the original prompt + PRODUCT.md already pinned scope, content, and direction. State what you're building, the visual lane, and end with one or two specific questions or a clear "confirm or override?" prompt. This is the default for typical craft requests with a clear prompt.
- **Full structured form (sections below)** when the task is genuinely ambiguous, multi-screen, or when the user asked for shape as a standalone step. Use this when the discipline of structure earns its weight.
Don't pad a clear brief into a long one to look thorough. A 70-line brief restating answers the user just gave is noise, not rigor. Equally, don't skip the confirmation pause to look efficient: the pause is the point.
If the user already said "approved" or "go" during discovery for the *exact direction you'd present*, that counts as confirmation; you may proceed without asking again. But if your brief adds anything the user hasn't seen and approved, you must stop and confirm.

| Product | PRODUCT.md exists and is not empty or placeholder (`[TODO]` markers, <200 chars). | Run `/impeccable teach`, refresh context, then resume. Never synthesize PRODUCT.md from the user's original prompt alone. |
| Command | The matching command reference is loaded when a sub-command is used. | Load the reference before continuing. |
| Craft | `/impeccable craft` has a user-confirmed shape brief for this task. `teach` / PRODUCT.md never counts as shape. | Run `/impeccable shape` and wait for explicit brief confirmation. |
| Image | Required visual probes / mocks are generated or skipped with a reason. | Resolve the image-generation gate in `shape.md` or `craft.md` before code. |
| Mutation | All active gates above pass. | Do not edit project files yet. |
1. Load context (PRODUCT.md / DESIGN.md) via the loader script.
2. Identify the register and load the matching register reference (brand.md or product.md).
3. **If the user invoked a sub-command (e.g. `craft`, `shape`, `audit`), load its reference file too.** This is non-negotiable: `craft` without `craft.md` loaded means you'll skip the shape-and-confirm step the user expects.
Codex-style agents must state this before editing files:
```text
IMPECCABLE_PREFLIGHT: context=pass product=pass command_reference=pass shape=pass|not_required image_gate=pass|skipped:<reason> mutation=open
```
For `/impeccable craft`, `shape=pass` is only valid after a separate user response approving the shape design brief, or when the user provided an already-confirmed brief in the request. Do not mark `shape=pass` after writing PRODUCT.md, summarizing assumptions, or drafting an unconfirmed brief yourself.
Other harnesses should follow the same checklist when they can expose this state.
Skipping these produces generic output that ignores the project.

# Craft Flow
Build a feature with impeccable UX and UI quality through a structured process: shape the design, land the visual direction, build real production code, then inspect and improve in-browser until the result meets a high-end studio bar.
Build a feature with impeccable UX and UI quality: shape the design, land the visual direction, build real production code, inspect and improve in-browser until it meets a high-end studio bar.
## Build Gate
Before writing code, you need: PRODUCT.md loaded, register identified and the matching reference loaded, and a confirmed design direction for this task (either from `shape` or supplied by the user). PRODUCT.md is project context, not a task-specific brief.
Craft cannot build until all of these are true:
Treat any approved visual direction (generated mock or stated reference) as a concrete contract for composition, hierarchy, density, atmosphere, signature motifs, and distinctive visual moves. Don't let mocks replace structure, copy, accessibility, or state design. But if the live result lacks the approved direction's major ingredients, the implementation is wrong.
1. PRODUCT context is valid and current.
2. The shape design brief is explicitly confirmed by the user for this task, unless the user already provided a confirmed brief.
3. Implementation references from the brief are loaded.
4. The shape visual probe decision is recorded: generated, skipped with reason, or already resolved.
5. The north-star mock decision is recorded: generated, skipped with reason, or not applicable.
## Step 0: Project Foundation
PRODUCT.md and `teach` answers do **not** satisfy the shape gate. They are project context only. A compact self-authored brief does not satisfy the shape gate either. `shape=pass` requires a separate user response approving the shape brief or an already-confirmed brief supplied by the user.
Before shape, before code: figure out what kind of project you're working in.
Invalid image-skip reasons include: "the final implementation will be semantic HTML/CSS/SVG", "the diagram should stay editable", "a raster mock would not be used directly", or "the product is fictional." Generated probes and mocks are direction artifacts; they are not implementation assets.
Look at the working directory. Run `ls`. Check for:
## Craft Contract
- An existing framework: `astro.config.mjs/ts`, `next.config.js/ts`, `nuxt.config.ts`, `svelte.config.js`, `vite.config.js/ts`, `package.json` with framework deps, `Cargo.toml` + Leptos/Yew, `Gemfile` + Rails. **If found, use it.** Do not start a parallel build, do not introduce a second framework, do not write to `dist/` or `build/` directly. Whatever pipeline the project has, respect it.
- An existing component library or design system: `src/components/`, `app/components/`, a `tokens.css` / `theme.ts`, an `astro.config` `integrations`. Read what's there before adding to it.
- An existing icon set: `lucide-react`, `@phosphor-icons/react`, `@iconify/*`, hand-rolled SVG sprites in `assets/icons/`. **Use what's already in the project**; don't introduce a second set.
Craft is not a first pass. It is a loop with these required artifacts:
If the directory is empty (greenfield), don't pick a framework silently. Ask the user via the AskUserQuestion tool, with sensible defaults framed by the brief:
1. Confirmed design brief from `shape`.
2. Approved visual direction, from generated probes / mocks when image generation is available.
3. Mock fidelity inventory: the visible ingredients from the approved direction that must survive into code.
4. Semantic, functional implementation using the project's real stack and conventions.
5. Browser evidence across relevant viewports.
6. At least one critique-and-fix pass after the first browser inspection, unless the first pass has no material defects.
```text
What should this be built on?
- Astro (default for content-led brand sites, landing pages, marketing surfaces)
- SvelteKit / Next.js / Nuxt (when the brief implies an app surface or significant interactivity)
- Single index.html (one-shot demo, prototype, or a deliberately framework-free experiment)
```
Do not let generated mockups replace interface structure, copy, accessibility, responsive behavior, or state design.

## Step 1: Shape the Design
Run /impeccable shape, passing along whatever feature description the user provided.
Run /impeccable shape, passing along whatever feature description the user provided. Shape is **required** for craft; it is what produces a confirmed direction.
Wait for the design brief to be fully confirmed by the user before proceeding. The brief is your blueprint, and every implementation decision should trace back to it.
Present the shape output and stop. Wait for the user to confirm, override, or course-correct before writing code.
If this craft run resumed after `teach` created PRODUCT.md, run shape now. Do not treat the teach interview, PRODUCT.md, or a summary of project context as a substitute for shape. Shape is task-specific and must cover scope, content/states, visual direction, constraints, anti-goals, probes when applicable, and explicit brief confirmation.
If the user already supplied a confirmed brief or ran shape separately, use it and skip this step.
If the user has already run /impeccable shape and has a confirmed design brief, skip this step and use the existing brief.
When the original prompt + PRODUCT.md already answer scope, content, and visual direction with no real ambiguity, the shape output can be **compact** (3-5 bullets stating what you're building and the visual lane, ending with one or two specific questions or "confirm or override"). The full 10-section structured brief is reserved for genuinely ambiguous, multi-screen, or stakeholder-heavy tasks. Don't pad a clear brief into a long one to look thorough; equally, don't skip the pause to look efficient.

## Step 3: Land the Visual Direction (Capability-Gated)
Before implementation, generate high-fidelity visual comps when all of these are true:
Generate high-fidelity visual comps before implementation when all three are true:
- The work is **net-new** or visually open-ended enough that composition exploration will improve the build.
- The brief's scope is **mid-fi, high-fi, or production-ready**.
- The current harness has **built-in image generation capability** (for example, Codex with a native image tool). Do **not** ask the user to set up external APIs, shell scripts, or one-off tooling just to do this.
- The work is net-new or visually open-ended enough that composition exploration will improve the build.
- The brief's scope is mid-fi, high-fi, or production-ready.
- The harness gives you native image generation (Codex's `image_gen`, an equivalent MCP tool). Don't ask the user to set up external APIs.
When those conditions are met, this step is mandatory for **both brand and product work** in Codex and any harness with built-in image generation. Use native image generation; in Codex, use the built-in `image_gen` tool via the imagegen skill. If image generation is unavailable, do not ask the user to install APIs or tooling. State in one line that the image step is skipped because the harness lacks native image generation, then proceed.
Do not skip this step because the eventual UI should be semantic, editable, code-native, responsive, or accessible. Those are implementation requirements, not reasons to avoid visual exploration.
### Purpose
Use the mock step to find a stronger visual lane than code-first generation would reliably discover on its own. The brief remains authoritative on user, purpose, content, constraints, states, and anti-goals. The mock clarifies composition, hierarchy, density, typography, and visual tone.
When met, this step is mandatory for both brand and product work. If image generation isn't available, skip silently. "The eventual UI is semantic/code-native/accessible" is not a reason to skip; those are implementation requirements, not exploration ones.
### What to generate
Generate **1 to 3** high-fidelity north-star comps based on the confirmed brief. If shape already produced direction probes, use those results as input and generate a more resolved mock from the winning lane, not another unrelated exploration.
Generate **1 to 3** high-fidelity north-star comps from the confirmed brief. If shape already produced direction probes, resolve the winning lane further, not an unrelated exploration. Comps must differ in primary visual direction, not just color.

- For product work, still push hierarchy, topology, density, and tone, but keep the comps grounded in realistic product structure and states.
- For landing pages and long-form brand surfaces, show enough of the next section or second fold to establish the system beyond the hero.

### Mock fidelity inventory
Before building, inventory the approved mock's major visible ingredients:
Inventory the approved mock's major visible ingredients:
- Hero silhouette and dominant composition.
- Signature motifs: planets, devices, portraits, charts, route lines, insets, badges, or other memorable objects.
- Nav and primary CTA treatment.
- Section sequence visible in the mock, especially the second fold.
- Image-native content the concept depends on.
- Typography, density, color/material treatment, and motion cues.

- Nav and primary CTA treatment
- Section sequence, especially the second fold
- Image-native content the concept depends on
- Typography, density, color/material treatment, motion cues
For each ingredient, decide how it will be implemented: semantic HTML/CSS/SVG, generated asset, sourced project asset, icon library, canvas/WebGL, or an explicitly accepted omission. Do not substitute a different hero composition or new visual driver after approval unless the user approves the change.
For each, decide implementation: semantic HTML/CSS/SVG, generated asset, sourced asset, icon library, canvas/WebGL, or accepted omission. Don't substitute a different hero composition or visual driver post-approval without user sign-off.
Treat the mock as a **north star**, not a screenshot to trace. Do **not** rasterize core UI text or let the mock override the confirmed brief. But if the live result lacks the mock's major visible ingredients, the implementation is wrong.
If a photographic, architectural, product, or place-led mock becomes generic CSS scenery / decorative diagrams / bullets / copy, stop and fix it. That's a broken implementation, not a harmless interpretation.
Treat the mock as a north star, not a screenshot to trace. Don't rasterize core UI text. But if the live result lacks the mock's major ingredients, the implementation is wrong.
## Step 4: Asset Extraction (Need-Gated)
If the chosen direction includes image-native visual ingredients that would materially improve the implementation, generate them as separate assets before building.
If the approved direction needs raster assets, create them before building. Do not replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy.
Good candidates:
Use the native asset producer (`impeccable_asset_producer` in Codex, `impeccable-asset-producer` in Claude Code) to create clean assets from the hi-fi mock and crops. If you do not have explicit permission to use agents, stop and ask:
- stickers
- badges
- seals
- tickets
- graphic labels
- textures
- abstract objects
- decorative marks
- non-semantic scene elements
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
For travel, editorial, portfolio, venue, product showcase, entertainment, education, or any other image-led brand surface, visual assets are usually core content, not decoration. Do not ship abstract CSS panels where the approved mock or subject matter calls for real imagery, generated plates, illustrations, maps, product/object renders, or destination scenes.
Do not skip asset production or silently do it inline. Inline asset production is allowed only if the user declines subagents, the harness cannot spawn the authorized agent, or the user explicitly asks for single-thread mode.
Do **not** export assets for core UI text, navigation, body copy, or any structure that should stay semantic and editable in code.
Pass the approved mock, crop/contact-sheet paths, output directory, dimensions/formats, transparency needs, constraints, and avoid list to the asset producer. Attach image generation capability to the spawned agent when the harness supports it; do not load image-generation reference material into the parent thread first.
Usually **1 to 5** extracted assets is enough. If the design can be built cleanly in HTML/CSS/SVG, prefer that over raster assets. If the mock contains major visual content that cannot be built credibly in code, asset extraction is not optional.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; use real/generated/stock imagery when the mock or subject matter calls for actual visual content.

### Production bar
- Use real or realistic content. Remove placeholder copy, placeholder images, dead links, fake controls, and unused scaffold before presenting.
- Preserve the approved mock's major ingredients. Missing hero objects, missing world/product imagery, different section structure, downgraded CTA/nav treatment, or generic replacements for distinctive motifs are blocking defects unless the user accepted the change.
- Build semantically first: real headings, landmarks, labels, form associations, button/link semantics, accessible names, and state announcements where needed.
- Calibrate spacing, alignment, grid placement, and vertical rhythm deliberately. Do not accept default gaps, arbitrary margins, unbalanced whitespace, or accidental optical misalignment.
- Make typography intentional: chosen font loading strategy, clear hierarchy, readable measure, stable line breaks, tuned wrapping, and no overflow at mobile or large desktop sizes.
- Design realistic state coverage: default, hover where supported, focus-visible, active, disabled, loading, error, success, empty, overflow, long text, short text, and first-run states where relevant.
- Make interaction quality feel finished: keyboard paths, touch targets, feedback timing, scroll behavior, transitions between states, and no hover-only functionality.
- Use icons from the project's established icon set when available. If no set exists, choose a coherent library or use accessible text controls; do not mix unrelated icon styles.
- Optimize imagery and media: correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset` / `picture` for raster assets, and no project-referenced asset left outside the workspace.
- Make motion feel premium: use atmospheric blur, filter, mask, shadow, or reveal effects when they improve the experience; avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- Preserve maintainability: reusable local patterns, clear component boundaries, project conventions, no rasterized UI text, and no hard-coded one-off hacks when a better local pattern exists.
- Fit the technical context: production build passes, no obvious console errors, no avoidable layout shift, no needless dependency, and no broken asset path.
- If you discover a design question that materially changes the brief or approved direction, stop and ask rather than guessing.
- **Real content.** No placeholder copy, placeholder images, dead links, fake controls, or unused scaffold at presentation time.

- **Realistic state coverage.** Default, hover, focus-visible, active, disabled, loading, error, success, empty, overflow, long/short text, first-run.
- **Finished interaction quality.** Keyboard paths, touch targets, feedback timing, scroll behavior, state transitions, no hover-only functionality.
- **Coherent icon set.** Use the project's established set; otherwise pick one library or use accessible text. Don't mix.
- **Respect the build pipeline.** Edit source files and run the project's build (`npm run build` or equivalent). Don't write to `build/` / `dist/` / `.next/` with `cat`, heredoc, or Bash redirects; that skips asset hashing, image optimization, code splitting, and CSS extraction, and produces output the dev server won't serve.
- **Verify image URLs before referencing them.** Use image-search MCP or web-fetch when available; guessed photo IDs ship as broken-image placeholders. Without verification, prefer fewer images you're confident about.
- **Optimized imagery and media.** Correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset`/`picture` for raster, no project-referenced asset left outside the workspace.
- **Premium motion.** Use atmospheric blur, filter, mask, shadow, reveal when they improve the experience. Avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- **Maintainable.** Reusable local patterns, clear component boundaries, project conventions. No rasterized UI text or one-off hacks when a local pattern exists.
- **Technically clean.** Production build passes, no console errors, no avoidable layout shift, no needless dependencies, no broken asset paths.
- **Ask when uncertain.** If a discovery materially changes the brief or approved direction, stop and ask. Don't guess.
## Step 6: Browser-Based Iteration
## Step 6: Iterate Visually
**This step is critical.** Do not stop after the first implementation pass.
Look at what you built like a designer would. Your eyes are whatever the harness gives you: a connected browser, a screenshotting tool, Playwright, or asking the user. Use them for responsive testing (mobile, tablet, desktop minimum) and general visual validation.
Open the result in a browser. In Codex, use browser-use or equivalent browser automation when available; otherwise use Playwright or ask the user for screenshots. Inspect screenshots, not just DOM or terminal output.
If your tool returns a file path, read the PNG back into the conversation. A screenshot you didn't read doesn't count.
### Required viewport pass
For long-form brand surfaces, inspect major sections individually. Thumbnails hide spacing, clipping, and cascade defects.
Check the experience at the viewports that matter for the brief. Default minimum:
After the first pass, write an honest critique against the brief, the approved mock's major ingredients (hero silhouette, motifs, imagery, nav/CTA, density), and impeccable's DON'Ts. Patch material defects and re-inspect. **Don't invent defects to demonstrate iteration.** A confident "first pass clean, shipping" beats a fake fix.
- Mobile narrow
- Tablet or small laptop
- Desktop wide
Actively check: responsive behavior (composes, not shrinks), every state (empty / error / loading / edge), craft details (spacing, alignment, hierarchy, contrast, motion timing, focus), performance basics. The exit bar: defensible in a high-end studio review.
For each viewport, capture or inspect the rendered state and look for visual defects: overlap, clipping, weak hierarchy, off-grid alignment, awkward whitespace, cramped controls, unreadable type, broken imagery, hover-only functionality, layout shift, and text overflow.
### Critique and fix loop
After the first browser pass, write a short critique for yourself and patch the implementation. Repeat browser inspection after fixes. Continue until no material issues remain against this checklist:
1. **Does it match the brief?** Compare the live result against every section of the design brief. Fix discrepancies.
2. **Does it match the approved mock?** Compare screenshots against the mock fidelity inventory: hero silhouette, major motifs, imagery, nav/CTA, section sequence, density, color/materials, and second-fold substance. Missing major ingredients are P0 defects.
3. **Does it pass the AI slop test?** If someone saw this and said "AI made this," would they believe it immediately? If yes, it needs more design intention.
4. **Check against impeccable's DON'T guidelines.** Fix any anti-pattern violations.
5. **Check every state.** Navigate through empty, error, loading, and edge case states. Each one should feel intentional, not like an afterthought.
6. **Check responsive behavior.** The design should adapt compositionally, not merely shrink.
7. **Check craft details.** Spacing consistency, optical alignment, type hierarchy, color contrast, image quality, icon coherence, interactive feedback, motion timing, and focus treatment.
8. **Check performance basics.** No obviously oversized images, avoidable layout thrash, blocking animations, or heavy assets without a reason.
The exit bar is not "it works." It is: the rendered result looks intentional at all checked viewports, all expected states are handled, no placeholders remain unless explicitly accepted, and the implementation quality would be defensible in a high-end studio review.

## Setup
Before any design work or file edits, pass these gates. Skipping them produces generic output that ignores the project.
Before any design work or file edits:
| Gate | Required check | If fail |
|---|---|---|
| Context | The PRODUCT.md / DESIGN.md loader result is known from `node .kiro/skills/impeccable/scripts/load-context.mjs`. | Run the loader before continuing. |
| Product | PRODUCT.md exists and is not empty or placeholder (`[TODO]` markers, <200 chars). | Run `/impeccable teach`, refresh context, then resume. Never synthesize PRODUCT.md from the user's original prompt alone. |
| Command | The matching command reference is loaded when a sub-command is used. | Load the reference before continuing. |
| Craft | `/impeccable craft` has a user-confirmed shape brief for this task. `teach` / PRODUCT.md never counts as shape. | Run `/impeccable shape` and wait for explicit brief confirmation. |
| Image | Required visual probes / mocks are generated or skipped with a reason. | Resolve the image-generation gate in `shape.md` or `craft.md` before code. |
| Mutation | All active gates above pass. | Do not edit project files yet. |
1. Load context (PRODUCT.md / DESIGN.md) via the loader script.
2. Identify the register and load the matching register reference (brand.md or product.md).
3. **If the user invoked a sub-command (e.g. `craft`, `shape`, `audit`), load its reference file too.** This is non-negotiable: `craft` without `craft.md` loaded means you'll skip the shape-and-confirm step the user expects.
Codex-style agents must state this before editing files:
```text
IMPECCABLE_PREFLIGHT: context=pass product=pass command_reference=pass shape=pass|not_required image_gate=pass|skipped:<reason> mutation=open
```
For `/impeccable craft`, `shape=pass` is only valid after a separate user response approving the shape design brief, or when the user provided an already-confirmed brief in the request. Do not mark `shape=pass` after writing PRODUCT.md, summarizing assumptions, or drafting an unconfirmed brief yourself.
Other harnesses should follow the same checklist when they can expose this state.
Skipping these produces generic output that ignores the project.

# Craft Flow
Build a feature with impeccable UX and UI quality through a structured process: shape the design, land the visual direction, build real production code, then inspect and improve in-browser until the result meets a high-end studio bar.
Build a feature with impeccable UX and UI quality: shape the design, land the visual direction, build real production code, inspect and improve in-browser until it meets a high-end studio bar.
## Build Gate
Before writing code, you need: PRODUCT.md loaded, register identified and the matching reference loaded, and a confirmed design direction for this task (either from `shape` or supplied by the user). PRODUCT.md is project context, not a task-specific brief.
Craft cannot build until all of these are true:
Treat any approved visual direction (generated mock or stated reference) as a concrete contract for composition, hierarchy, density, atmosphere, signature motifs, and distinctive visual moves. Don't let mocks replace structure, copy, accessibility, or state design. But if the live result lacks the approved direction's major ingredients, the implementation is wrong.
1. PRODUCT context is valid and current.
2. The shape design brief is explicitly confirmed by the user for this task, unless the user already provided a confirmed brief.
3. Implementation references from the brief are loaded.
4. The shape visual probe decision is recorded: generated, skipped with reason, or already resolved.
5. The north-star mock decision is recorded: generated, skipped with reason, or not applicable.
## Step 0: Project Foundation
PRODUCT.md and `teach` answers do **not** satisfy the shape gate. They are project context only. A compact self-authored brief does not satisfy the shape gate either. `shape=pass` requires a separate user response approving the shape brief or an already-confirmed brief supplied by the user.
Before shape, before code: figure out what kind of project you're working in.
Invalid image-skip reasons include: "the final implementation will be semantic HTML/CSS/SVG", "the diagram should stay editable", "a raster mock would not be used directly", or "the product is fictional." Generated probes and mocks are direction artifacts; they are not implementation assets.
Look at the working directory. Run `ls`. Check for:
## Craft Contract
- An existing framework: `astro.config.mjs/ts`, `next.config.js/ts`, `nuxt.config.ts`, `svelte.config.js`, `vite.config.js/ts`, `package.json` with framework deps, `Cargo.toml` + Leptos/Yew, `Gemfile` + Rails. **If found, use it.** Do not start a parallel build, do not introduce a second framework, do not write to `dist/` or `build/` directly. Whatever pipeline the project has, respect it.
- An existing component library or design system: `src/components/`, `app/components/`, a `tokens.css` / `theme.ts`, an `astro.config` `integrations`. Read what's there before adding to it.
- An existing icon set: `lucide-react`, `@phosphor-icons/react`, `@iconify/*`, hand-rolled SVG sprites in `assets/icons/`. **Use what's already in the project**; don't introduce a second set.
Craft is not a first pass. It is a loop with these required artifacts:
If the directory is empty (greenfield), don't pick a framework silently. Ask the user via the AskUserQuestion tool, with sensible defaults framed by the brief:
1. Confirmed design brief from `shape`.
2. Approved visual direction, from generated probes / mocks when image generation is available.
3. Mock fidelity inventory: the visible ingredients from the approved direction that must survive into code.
4. Semantic, functional implementation using the project's real stack and conventions.
5. Browser evidence across relevant viewports.
6. At least one critique-and-fix pass after the first browser inspection, unless the first pass has no material defects.
```text
What should this be built on?
- Astro (default for content-led brand sites, landing pages, marketing surfaces)
- SvelteKit / Next.js / Nuxt (when the brief implies an app surface or significant interactivity)
- Single index.html (one-shot demo, prototype, or a deliberately framework-free experiment)
```
Do not let generated mockups replace interface structure, copy, accessibility, responsive behavior, or state design. But do treat the approved mock as a concrete visual contract for composition, hierarchy, density, atmosphere, signature motifs, image needs, and distinctive visual moves. "North star" means "preserve the important visible ingredients in semantic code," not "use it as loose mood."
Default: Astro for brand briefs, the project's existing framework for product briefs. Ask once; don't re-ask mid-task.
## Step 1: Shape the Design
Run /impeccable shape, passing along whatever feature description the user provided.
Run /impeccable shape, passing along whatever feature description the user provided. Shape is **required** for craft; it is what produces a confirmed direction.
Wait for the design brief to be fully confirmed by the user before proceeding. The brief is your blueprint, and every implementation decision should trace back to it.
Present the shape output and stop. Wait for the user to confirm, override, or course-correct before writing code.
If this craft run resumed after `teach` created PRODUCT.md, run shape now. Do not treat the teach interview, PRODUCT.md, or a summary of project context as a substitute for shape. Shape is task-specific and must cover scope, content/states, visual direction, constraints, anti-goals, probes when applicable, and explicit brief confirmation.
If the user already supplied a confirmed brief or ran shape separately, use it and skip this step.
If the user has already run /impeccable shape and has a confirmed design brief, skip this step and use the existing brief.
When the original prompt + PRODUCT.md already answer scope, content, and visual direction with no real ambiguity, the shape output can be **compact** (3-5 bullets stating what you're building and the visual lane, ending with one or two specific questions or "confirm or override"). The full 10-section structured brief is reserved for genuinely ambiguous, multi-screen, or stakeholder-heavy tasks. Don't pad a clear brief into a long one to look thorough; equally, don't skip the pause to look efficient.

## Step 3: Land the Visual Direction (Capability-Gated)
Before implementation, generate high-fidelity visual comps when all of these are true:
Generate high-fidelity visual comps before implementation when all three are true:
- The work is **net-new** or visually open-ended enough that composition exploration will improve the build.
- The brief's scope is **mid-fi, high-fi, or production-ready**.
- The current harness has **built-in image generation capability** (for example, Codex with a native image tool). Do **not** ask the user to set up external APIs, shell scripts, or one-off tooling just to do this.
- The work is net-new or visually open-ended enough that composition exploration will improve the build.
- The brief's scope is mid-fi, high-fi, or production-ready.
- The harness gives you native image generation (Codex's `image_gen`, an equivalent MCP tool). Don't ask the user to set up external APIs.
When those conditions are met, this step is mandatory for **both brand and product work** in Codex and any harness with built-in image generation. Use native image generation; in Codex, use the built-in `image_gen` tool via the imagegen skill. If image generation is unavailable, do not ask the user to install APIs or tooling. State in one line that the image step is skipped because the harness lacks native image generation, then proceed.
Do not skip this step because the eventual UI should be semantic, editable, code-native, responsive, or accessible. Those are implementation requirements, not reasons to avoid visual exploration.
### Purpose
Use the mock step to find a stronger visual lane than code-first generation would reliably discover on its own. The brief remains authoritative on user, purpose, content, constraints, states, and anti-goals. The mock clarifies composition, hierarchy, density, typography, and visual tone.
When met, this step is mandatory for both brand and product work. If image generation isn't available, skip silently. "The eventual UI is semantic/code-native/accessible" is not a reason to skip; those are implementation requirements, not exploration ones.
### What to generate
Generate **1 to 3** high-fidelity north-star comps based on the confirmed brief. If shape already produced direction probes, use those results as input and generate a more resolved mock from the winning lane, not another unrelated exploration.
Generate **1 to 3** high-fidelity north-star comps from the confirmed brief. If shape already produced direction probes, resolve the winning lane further, not an unrelated exploration. Comps must differ in primary visual direction, not just color.

- For product work, still push hierarchy, topology, density, and tone, but keep the comps grounded in realistic product structure and states.
- For landing pages and long-form brand surfaces, show enough of the next section or second fold to establish the system beyond the hero.

### Mock fidelity inventory
Before building, inventory the approved mock's major visible ingredients:
Inventory the approved mock's major visible ingredients:
- Hero silhouette and dominant composition.
- Signature motifs: planets, devices, portraits, charts, route lines, insets, badges, or other memorable objects.
- Nav and primary CTA treatment.

- Image-native content the concept depends on.
- Typography, density, color/material treatment, and motion cues.

For each ingredient, decide how it will be implemented: semantic HTML/CSS/SVG, generated asset, sourced project asset, icon library, canvas/WebGL, or an explicitly accepted omission. Do not substitute a different hero composition or new visual driver after approval unless the user approves the change.

Treat the mock as a north star, not a screenshot to trace. Don't rasterize core UI text. But if the live result lacks the mock's major ingredients, the implementation is wrong.
## Step 4: Asset Extraction (Need-Gated)
If the chosen direction includes image-native visual ingredients that would materially improve the implementation, generate them as separate assets before building.
If the approved direction needs raster assets, create them before building. Do not replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy.
Good candidates:
Use the native asset producer (`impeccable_asset_producer` in Codex, `impeccable-asset-producer` in Claude Code) to create clean assets from the hi-fi mock and crops. If you do not have explicit permission to use agents, stop and ask:
- stickers
- badges
- seals
- tickets
- graphic labels
- textures
- abstract objects
- decorative marks
- non-semantic scene elements
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
For travel, editorial, portfolio, venue, product showcase, entertainment, education, or any other image-led brand surface, visual assets are usually core content, not decoration. Do not ship abstract CSS panels where the approved mock or subject matter calls for real imagery, generated plates, illustrations, maps, product/object renders, or destination scenes.
Do not skip asset production or silently do it inline. Inline asset production is allowed only if the user declines subagents, the harness cannot spawn the authorized agent, or the user explicitly asks for single-thread mode.
Do **not** export assets for core UI text, navigation, body copy, or any structure that should stay semantic and editable in code.
Pass the approved mock, crop/contact-sheet paths, output directory, dimensions/formats, transparency needs, constraints, and avoid list to the asset producer. Attach image generation capability to the spawned agent when the harness supports it; do not load image-generation reference material into the parent thread first.
Usually **1 to 5** extracted assets is enough. If the design can be built cleanly in HTML/CSS/SVG, prefer that over raster assets. If the mock contains major visual content that cannot be built credibly in code, asset extraction is not optional.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; use real/generated/stock imagery when the mock or subject matter calls for actual visual content.

- Build semantically first: real headings, landmarks, labels, form associations, button/link semantics, accessible names, and state announcements where needed.
- Calibrate spacing, alignment, grid placement, and vertical rhythm deliberately. Do not accept default gaps, arbitrary margins, unbalanced whitespace, or accidental optical misalignment.
- Make typography intentional: chosen font loading strategy, clear hierarchy, readable measure, stable line breaks, tuned wrapping, and no overflow at mobile or large desktop sizes.
- Design realistic state coverage: default, hover where supported, focus-visible, active, disabled, loading, error, success, empty, overflow, long text, short text, and first-run states where relevant.
- Make interaction quality feel finished: keyboard paths, touch targets, feedback timing, scroll behavior, transitions between states, and no hover-only functionality.
- Use icons from the project's established icon set when available. If no set exists, choose a coherent library or use accessible text controls; do not mix unrelated icon styles.
- Optimize imagery and media: correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset` / `picture` for raster assets, and no project-referenced asset left outside the workspace.
- Make motion feel premium: use atmospheric blur, filter, mask, shadow, or reveal effects when they improve the experience; avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- Preserve maintainability: reusable local patterns, clear component boundaries, project conventions, no rasterized UI text, and no hard-coded one-off hacks when a better local pattern exists.
- Fit the technical context: production build passes, no obvious console errors, no avoidable layout shift, no needless dependency, and no broken asset path.

- **Finished interaction quality.** Keyboard paths, touch targets, feedback timing, scroll behavior, state transitions, no hover-only functionality.
- **Coherent icon set.** Use the project's established set; otherwise pick one library or use accessible text. Don't mix.
- **Respect the build pipeline.** Edit source files and run the project's build (`npm run build` or equivalent). Don't write to `build/` / `dist/` / `.next/` with `cat`, heredoc, or Bash redirects; that skips asset hashing, image optimization, code splitting, and CSS extraction, and produces output the dev server won't serve.
- **Verify image URLs before referencing them.** Use image-search MCP or web-fetch when available; guessed photo IDs ship as broken-image placeholders. Without verification, prefer fewer images you're confident about.
- **Optimized imagery and media.** Correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset`/`picture` for raster, no project-referenced asset left outside the workspace.
- **Premium motion.** Use atmospheric blur, filter, mask, shadow, reveal when they improve the experience. Avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- **Maintainable.** Reusable local patterns, clear component boundaries, project conventions. No rasterized UI text or one-off hacks when a local pattern exists.
- **Technically clean.** Production build passes, no console errors, no avoidable layout shift, no needless dependencies, no broken asset paths.
- **Ask when uncertain.** If a discovery materially changes the brief or approved direction, stop and ask. Don't guess.
## Step 6: Browser-Based Iteration
## Step 6: Iterate Visually
**This step is critical.** Do not stop after the first implementation pass.
Look at what you built like a designer would. Your eyes are whatever the harness gives you: a connected browser, a screenshotting tool, Playwright, or asking the user. Use them for responsive testing (mobile, tablet, desktop minimum) and general visual validation.
Open the result in a browser. In Codex, use browser-use or equivalent browser automation when available; otherwise use Playwright or ask the user for screenshots. Inspect screenshots, not just DOM or terminal output.
If your tool returns a file path, read the PNG back into the conversation. A screenshot you didn't read doesn't count.
### Required viewport pass
For long-form brand surfaces, inspect major sections individually. Thumbnails hide spacing, clipping, and cascade defects.
Check the experience at the viewports that matter for the brief. Default minimum:
After the first pass, write an honest critique against the brief, the approved mock's major ingredients (hero silhouette, motifs, imagery, nav/CTA, density), and impeccable's DON'Ts. Patch material defects and re-inspect. **Don't invent defects to demonstrate iteration.** A confident "first pass clean, shipping" beats a fake fix.
- Mobile narrow
- Tablet or small laptop
- Desktop wide
Actively check: responsive behavior (composes, not shrinks), every state (empty / error / loading / edge), craft details (spacing, alignment, hierarchy, contrast, motion timing, focus), performance basics. The exit bar: defensible in a high-end studio review.
For each viewport, capture or inspect the rendered state and look for visual defects: overlap, clipping, weak hierarchy, off-grid alignment, awkward whitespace, cramped controls, unreadable type, broken imagery, hover-only functionality, layout shift, and text overflow.
### Critique and fix loop
After the first browser pass, write a short critique for yourself and patch the implementation. Repeat browser inspection after fixes. Continue until no material issues remain against this checklist:
1. **Does it match the brief?** Compare the live result against every section of the design brief. Fix discrepancies.
2. **Does it match the approved mock?** Compare screenshots against the mock fidelity inventory: hero silhouette, major motifs, imagery, nav/CTA, section sequence, density, color/materials, and second-fold substance. Missing major ingredients are P0 defects.
3. **Does it pass the AI slop test?** If someone saw this and said "AI made this," would they believe it immediately? If yes, it needs more design intention.
4. **Check against impeccable's DON'T guidelines.** Fix any anti-pattern violations.
5. **Check every state.** Navigate through empty, error, loading, and edge case states. Each one should feel intentional, not like an afterthought.
6. **Check responsive behavior.** The design should adapt compositionally, not merely shrink.
7. **Check craft details.** Spacing consistency, optical alignment, type hierarchy, color contrast, image quality, icon coherence, interactive feedback, motion timing, and focus treatment.
8. **Check performance basics.** No obviously oversized images, avoidable layout thrash, blocking animations, or heavy assets without a reason.
The exit bar is not "it works." It is: the rendered result looks intentional at all checked viewports, all expected states are handled, no placeholders remain unless explicitly accepted, and the implementation quality would be defensible in a high-end studio review.

3. **Bake in parameter values while rewriting selectors.** For `@scope ([data-impeccable-variant="N"])` wrappers: retarget to real, semantic classes on the accepted HTML (`.why-visual--v2 .v2-label { … }`). For `:scope[data-p-<id>="VALUE"]` selectors: keep only the branch matching the chosen value from the param-values comment; drop the others (they're dead after accept). For `var(--p-<id>, DEFAULT)` in the CSS: either substitute the literal value, or if the param is still useful as a knob going forward, leave the var and update its initial declaration to the chosen value.
4. **Unwrap the accepted content.** Delete the `<div data-impeccable-variant="N" style="display: contents">` that wraps it. Drop `data-impeccable-params` and any `data-p-*` attributes from it; those are live-mode plumbing, not source.
5. **Delete the inline `<style>` block, the `<!-- impeccable-param-values -->` comment if present, and both `<!-- impeccable-carbonize-start/end -->` markers.** Also drop any `@scope` rules for variants other than the accepted one; those are dead code now.

After the interview and any required probes, present a brief and **end your response**. The user must confirm before any implementation runs. Do not present a brief and then continue to code in the same response, even if the brief feels obvious to you. The user's confirmation is the gate.
**Choose the brief shape based on how clear the answers are:**
- **Compact form (3-5 bullets)** when discovery was crisp and the original prompt + PRODUCT.md already pinned scope, content, and direction. State what you're building, the visual lane, and end with one or two specific questions or a clear "confirm or override?" prompt. This is the default for typical craft requests with a clear prompt.

| Mutation | All active gates above pass. | Do not edit project files yet. |
1. Load context (PRODUCT.md / DESIGN.md) via the loader script.
2. Identify the register and load the matching register reference (brand.md or product.md).
3. **If the user invoked a sub-command (e.g. `craft`, `shape`, `audit`), load its reference file too.** This is non-negotiable: `craft` without `craft.md` loaded means you'll skip the shape-and-confirm step the user expects.
Codex-style agents must state this before editing files:
```text
IMPECCABLE_PREFLIGHT: context=pass product=pass command_reference=pass shape=pass|not_required image_gate=pass|skipped:<reason> mutation=open
```
For `/impeccable craft`, `shape=pass` is only valid after a separate user response approving the shape design brief, or when the user provided an already-confirmed brief in the request. Do not mark `shape=pass` after writing PRODUCT.md, summarizing assumptions, or drafting an unconfirmed brief yourself.

# Craft Flow
Build a feature with impeccable UX and UI quality through a structured process: shape the design, land the visual direction, build real production code, then inspect and improve in-browser until the result meets a high-end studio bar.
Build a feature with impeccable UX and UI quality: shape the design, land the visual direction, build real production code, inspect and improve in-browser until it meets a high-end studio bar.
## Build Gate
Before writing code, you need: PRODUCT.md loaded, register identified and the matching reference loaded, and a confirmed design direction for this task (either from `shape` or supplied by the user). PRODUCT.md is project context, not a task-specific brief.
Craft cannot build until all of these are true:
Treat any approved visual direction (generated mock or stated reference) as a concrete contract for composition, hierarchy, density, atmosphere, signature motifs, and distinctive visual moves. Don't let mocks replace structure, copy, accessibility, or state design. But if the live result lacks the approved direction's major ingredients, the implementation is wrong.
1. PRODUCT context is valid and current.
2. The shape design brief is explicitly confirmed by the user for this task, unless the user already provided a confirmed brief.
3. Implementation references from the brief are loaded.
4. The shape visual probe decision is recorded: generated, skipped with reason, or already resolved.
5. The north-star mock decision is recorded: generated, skipped with reason, or not applicable.
## Step 0: Project Foundation
PRODUCT.md and `teach` answers do **not** satisfy the shape gate. They are project context only. A compact self-authored brief does not satisfy the shape gate either. `shape=pass` requires a separate user response approving the shape brief or an already-confirmed brief supplied by the user.
Before shape, before code: figure out what kind of project you're working in.
Invalid image-skip reasons include: "the final implementation will be semantic HTML/CSS/SVG", "the diagram should stay editable", "a raster mock would not be used directly", or "the product is fictional." Generated probes and mocks are direction artifacts; they are not implementation assets.
Look at the working directory. Run `ls`. Check for:
## Craft Contract
- An existing framework: `astro.config.mjs/ts`, `next.config.js/ts`, `nuxt.config.ts`, `svelte.config.js`, `vite.config.js/ts`, `package.json` with framework deps, `Cargo.toml` + Leptos/Yew, `Gemfile` + Rails. **If found, use it.** Do not start a parallel build, do not introduce a second framework, do not write to `dist/` or `build/` directly. Whatever pipeline the project has, respect it.
- An existing component library or design system: `src/components/`, `app/components/`, a `tokens.css` / `theme.ts`, an `astro.config` `integrations`. Read what's there before adding to it.
- An existing icon set: `lucide-react`, `@phosphor-icons/react`, `@iconify/*`, hand-rolled SVG sprites in `assets/icons/`. **Use what's already in the project**; don't introduce a second set.
Craft is not a first pass. It is a loop with these required artifacts:
If the directory is empty (greenfield), don't pick a framework silently. Ask the user via the AskUserQuestion tool, with sensible defaults framed by the brief:
1. Confirmed design brief from `shape`.
2. Approved visual direction, from generated probes / mocks when image generation is available.
3. Mock fidelity inventory: the visible ingredients from the approved direction that must survive into code.
4. Semantic, functional implementation using the project's real stack and conventions.
5. Browser evidence across relevant viewports.
6. At least one critique-and-fix pass after the first browser inspection, unless the first pass has no material defects.
```text
What should this be built on?
- Astro (default for content-led brand sites, landing pages, marketing surfaces)
- SvelteKit / Next.js / Nuxt (when the brief implies an app surface or significant interactivity)
- Single index.html (one-shot demo, prototype, or a deliberately framework-free experiment)
```
Do not let generated mockups replace interface structure, copy, accessibility, responsive behavior, or state design. But do treat the approved mock as a concrete visual contract for composition, hierarchy, density, atmosphere, signature motifs, image needs, and distinctive visual moves. "North star" means "preserve the important visible ingredients in semantic code," not "use it as loose mood."
Default: Astro for brand briefs, the project's existing framework for product briefs. Ask once; don't re-ask mid-task.
## Step 1: Shape the Design
Run /impeccable shape, passing along whatever feature description the user provided.
Run /impeccable shape, passing along whatever feature description the user provided. Shape is **required** for craft; it is what produces a confirmed direction.
Wait for the design brief to be fully confirmed by the user before proceeding. The brief is your blueprint, and every implementation decision should trace back to it.
Present the shape output and stop. Wait for the user to confirm, override, or course-correct before writing code.
If this craft run resumed after `teach` created PRODUCT.md, run shape now. Do not treat the teach interview, PRODUCT.md, or a summary of project context as a substitute for shape. Shape is task-specific and must cover scope, content/states, visual direction, constraints, anti-goals, probes when applicable, and explicit brief confirmation.
If the user already supplied a confirmed brief or ran shape separately, use it and skip this step.
If the user has already run /impeccable shape and has a confirmed design brief, skip this step and use the existing brief.
When the original prompt + PRODUCT.md already answer scope, content, and visual direction with no real ambiguity, the shape output can be **compact** (3-5 bullets stating what you're building and the visual lane, ending with one or two specific questions or "confirm or override"). The full 10-section structured brief is reserved for genuinely ambiguous, multi-screen, or stakeholder-heavy tasks.

Before implementation, generate high-fidelity visual comps when all of these are true:
Generate high-fidelity visual comps before implementation when all three are true:

- The harness gives you native image generation (Codex's `image_gen`, an equivalent MCP tool). Don't ask the user to set up external APIs.
When those conditions are met, this step is mandatory for **both brand and product work** in Codex and any harness with built-in image generation. Use native image generation; in Codex, use the built-in `image_gen` tool via the imagegen skill. If image generation is unavailable, do not ask the user to install APIs or tooling. State in one line that the image step is skipped because the harness lacks native image generation, then proceed.
Do not skip this step because the eventual UI should be semantic, editable, code-native, responsive, or accessible. Those are implementation requirements, not reasons to avoid visual exploration.
### Purpose
Use the mock step to find a stronger visual lane than code-first generation would reliably discover on its own. The brief remains authoritative on user, purpose, content, constraints, states, and anti-goals. The mock clarifies composition, hierarchy, density, typography, and visual tone.
When met, this step is mandatory for both brand and product work. If image generation isn't available, skip silently. "The eventual UI is semantic/code-native/accessible" is not a reason to skip; those are implementation requirements, not exploration ones.

Before building, inventory the approved mock's major visible ingredients:
Inventory the approved mock's major visible ingredients:
- Hero silhouette and dominant composition.
- Signature motifs: planets, devices, portraits, charts, route lines, insets, badges, or other memorable objects.
- Nav and primary CTA treatment.

- Image-native content the concept depends on.

For each ingredient, decide how it will be implemented: semantic HTML/CSS/SVG, generated asset, sourced project asset, icon library, canvas/WebGL, or an explicitly accepted omission. Do not substitute a different hero composition or new visual driver after approval unless the user approves the change.
For each, decide implementation: semantic HTML/CSS/SVG, generated asset, sourced asset, icon library, canvas/WebGL, or accepted omission. Don't substitute a different hero composition or visual driver post-approval without user sign-off.

If a photographic, architectural, product, or place-led mock becomes generic CSS scenery / decorative diagrams / bullets / copy, stop and fix it. That's a broken implementation, not a harmless interpretation.

Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
For travel, editorial, portfolio, venue, product showcase, entertainment, education, or any other image-led brand surface, visual assets are usually core content, not decoration. Do not ship abstract CSS panels where the approved mock or subject matter calls for real imagery, generated plates, illustrations, maps, product/object renders, or destination scenes.
Do not skip asset production or silently do it inline. Inline asset production is allowed only if the user declines subagents, the harness cannot spawn the authorized agent, or the user explicitly asks for single-thread mode.
Do **not** export assets for core UI text, navigation, body copy, or any structure that should stay semantic and editable in code.
Pass the approved mock, crop/contact-sheet paths, output directory, dimensions/formats, transparency needs, constraints, and avoid list to the asset producer. Attach image generation capability to the spawned agent when the harness supports it; do not load image-generation reference material into the parent thread first.
Usually **1 to 5** extracted assets is enough. If the design can be built cleanly in HTML/CSS/SVG, prefer that over raster assets. If the mock contains major visual content that cannot be built credibly in code, asset extraction is not optional.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; use real/generated/stock imagery when the mock or subject matter calls for actual visual content.

### Production bar
- Use real or realistic content. Remove placeholder copy, placeholder images, dead links, fake controls, and unused scaffold before presenting.
- Preserve the approved mock's major ingredients. Missing hero objects, missing world/product imagery, different section structure, downgraded CTA/nav treatment, or generic replacements for distinctive motifs are blocking defects unless the user accepted the change.
- Build semantically first: real headings, landmarks, labels, form associations, button/link semantics, accessible names, and state announcements where needed.
- Calibrate spacing, alignment, grid placement, and vertical rhythm deliberately. Do not accept default gaps, arbitrary margins, unbalanced whitespace, or accidental optical misalignment.
- Make typography intentional: chosen font loading strategy, clear hierarchy, readable measure, stable line breaks, tuned wrapping, and no overflow at mobile or large desktop sizes.
- Design realistic state coverage: default, hover where supported, focus-visible, active, disabled, loading, error, success, empty, overflow, long text, short text, and first-run states where relevant.
- Make interaction quality feel finished: keyboard paths, touch targets, feedback timing, scroll behavior, transitions between states, and no hover-only functionality.
- Use icons from the project's established icon set when available. If no set exists, choose a coherent library or use accessible text controls; do not mix unrelated icon styles.
- Optimize imagery and media: correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset` / `picture` for raster assets, and no project-referenced asset left outside the workspace.
- Make motion feel premium: use atmospheric blur, filter, mask, shadow, or reveal effects when they improve the experience; avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- Preserve maintainability: reusable local patterns, clear component boundaries, project conventions, no rasterized UI text, and no hard-coded one-off hacks when a better local pattern exists.
- Fit the technical context: production build passes, no obvious console errors, no avoidable layout shift, no needless dependency, and no broken asset path.
- If you discover a design question that materially changes the brief or approved direction, stop and ask rather than guessing.
- **Real content.** No placeholder copy, placeholder images, dead links, fake controls, or unused scaffold at presentation time.
- **Preserve the approved mock's major ingredients.** Missing hero objects, world/product imagery, section structure, CTA/nav treatment, or distinctive motifs are blocking defects unless the user accepted the change.
- **Semantic first.** Real headings, landmarks, labels, form associations, button/link semantics, accessible names, state announcements where needed.
- **Deliberate spacing and alignment.** No default gaps, arbitrary margins, unbalanced whitespace, or accidental optical misalignment.
- **Intentional typography.** Chosen loading strategy, clear hierarchy, readable measure, stable line breaks, no overflow at any width.
- **Realistic state coverage.** Default, hover, focus-visible, active, disabled, loading, error, success, empty, overflow, long/short text, first-run.
- **Finished interaction quality.** Keyboard paths, touch targets, feedback timing, scroll behavior, state transitions, no hover-only functionality.
- **Coherent icon set.** Use the project's established set; otherwise pick one library or use accessible text. Don't mix.
- **Respect the build pipeline.** Edit source files and run the project's build (`npm run build` or equivalent). Don't write to `build/` / `dist/` / `.next/` with `cat`, heredoc, or Bash redirects; that skips asset hashing, image optimization, code splitting, and CSS extraction, and produces output the dev server won't serve.
- **Verify image URLs before referencing them.** Use image-search MCP or web-fetch when available; guessed photo IDs ship as broken-image placeholders. Without verification, prefer fewer images you're confident about.
- **Optimized imagery and media.** Correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset`/`picture` for raster, no project-referenced asset left outside the workspace.
- **Premium motion.** Use atmospheric blur, filter, mask, shadow, reveal when they improve the experience. Avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- **Maintainable.** Reusable local patterns, clear component boundaries, project conventions. No rasterized UI text or one-off hacks when a local pattern exists.
- **Technically clean.** Production build passes, no console errors, no avoidable layout shift, no needless dependencies, no broken asset paths.
- **Ask when uncertain.** If a discovery materially changes the brief or approved direction, stop and ask. Don't guess.
## Step 6: Browser-Based Iteration
## Step 6: Iterate Visually
**This step is critical.** Do not stop after the first implementation pass.
Look at what you built like a designer would. Your eyes are whatever the harness gives you: a connected browser, a screenshotting tool, Playwright, or asking the user. Use them for responsive testing (mobile, tablet, desktop minimum) and general visual validation.
Open the result in a browser. In Codex, use browser-use or equivalent browser automation when available; otherwise use Playwright or ask the user for screenshots. Inspect screenshots, not just DOM or terminal output.
If your tool returns a file path, read the PNG back into the conversation. A screenshot you didn't read doesn't count.
### Required viewport pass
For long-form brand surfaces, inspect major sections individually. Thumbnails hide spacing, clipping, and cascade defects.
Check the experience at the viewports that matter for the brief. Default minimum:
After the first pass, write an honest critique against the brief, the approved mock's major ingredients (hero silhouette, motifs, imagery, nav/CTA, density), and impeccable's DON'Ts. Patch material defects and re-inspect. **Don't invent defects to demonstrate iteration.** A confident "first pass clean, shipping" beats a fake fix.
- Mobile narrow
- Tablet or small laptop
- Desktop wide
Actively check: responsive behavior (composes, not shrinks), every state (empty / error / loading / edge), craft details (spacing, alignment, hierarchy, contrast, motion timing, focus), performance basics. The exit bar: defensible in a high-end studio review.
For each viewport, capture or inspect the rendered state and look for visual defects: overlap, clipping, weak hierarchy, off-grid alignment, awkward whitespace, cramped controls, unreadable type, broken imagery, hover-only functionality, layout shift, and text overflow.
### Critique and fix loop
After the first browser pass, write a short critique for yourself and patch the implementation. Repeat browser inspection after fixes. Continue until no material issues remain against this checklist:
1. **Does it match the brief?** Compare the live result against every section of the design brief. Fix discrepancies.
2. **Does it match the approved mock?** Compare screenshots against the mock fidelity inventory: hero silhouette, major motifs, imagery, nav/CTA, section sequence, density, color/materials, and second-fold substance. Missing major ingredients are P0 defects.
3. **Does it pass the AI slop test?** If someone saw this and said "AI made this," would they believe it immediately? If yes, it needs more design intention.
4. **Check against impeccable's DON'T guidelines.** Fix any anti-pattern violations.
5. **Check every state.** Navigate through empty, error, loading, and edge case states. Each one should feel intentional, not like an afterthought.
6. **Check responsive behavior.** The design should adapt compositionally, not merely shrink.
7. **Check craft details.** Spacing consistency, optical alignment, type hierarchy, color contrast, image quality, icon coherence, interactive feedback, motion timing, and focus treatment.
8. **Check performance basics.** No obviously oversized images, avoidable layout thrash, blocking animations, or heavy assets without a reason.
The exit bar is not "it works." It is: the rendered result looks intentional at all checked viewports, all expected states are handled, no placeholders remain unless explicitly accepted, and the implementation quality would be defensible in a high-end studio review.

After the interview and any required probes, present a brief and **end your response**. The user must confirm before any implementation runs. Do not present a brief and then continue to code in the same response, even if the brief feels obvious to you. The user's confirmation is the gate.
**Choose the brief shape based on how clear the answers are:**
- **Compact form (3-5 bullets)** when discovery was crisp and the original prompt + PRODUCT.md already pinned scope, content, and direction. State what you're building, the visual lane, and end with one or two specific questions or a clear "confirm or override?" prompt. This is the default for typical craft requests with a clear prompt.
- **Full structured form (sections below)** when the task is genuinely ambiguous, multi-screen, or when the user asked for shape as a standalone step. Use this when the discipline of structure earns its weight.
Don't pad a clear brief into a long one to look thorough. A 70-line brief restating answers the user just gave is noise, not rigor. Equally, don't skip the confirmation pause to look efficient: the pause is the point.

1. Load context (PRODUCT.md / DESIGN.md) via the loader script.
2. Identify the register and load the matching register reference (brand.md or product.md).
3. **If the user invoked a sub-command (e.g. `craft`, `shape`, `audit`), load its reference file too.** This is non-negotiable: `craft` without `craft.md` loaded means you'll skip the shape-and-confirm step the user expects.
Codex-style agents must state this before editing files:
```text
IMPECCABLE_PREFLIGHT: context=pass product=pass command_reference=pass shape=pass|not_required image_gate=pass|skipped:<reason> mutation=open
```
For `/impeccable craft`, `shape=pass` is only valid after a separate user response approving the shape design brief, or when the user provided an already-confirmed brief in the request. Do not mark `shape=pass` after writing PRODUCT.md, summarizing assumptions, or drafting an unconfirmed brief yourself.

Build a feature with impeccable UX and UI quality: shape the design, land the visual direction, build real production code, inspect and improve in-browser until it meets a high-end studio bar.
## Build Gate
Before writing code, you need: PRODUCT.md loaded, register identified and the matching reference loaded, and a confirmed design direction for this task (either from `shape` or supplied by the user). PRODUCT.md is project context, not a task-specific brief.
Craft cannot build until all of these are true:
Treat any approved visual direction (generated mock or stated reference) as a concrete contract for composition, hierarchy, density, atmosphere, signature motifs, and distinctive visual moves. Don't let mocks replace structure, copy, accessibility, or state design. But if the live result lacks the approved direction's major ingredients, the implementation is wrong.
1. PRODUCT context is valid and current.
2. The shape design brief is explicitly confirmed by the user for this task, unless the user already provided a confirmed brief.
3. Implementation references from the brief are loaded.
4. The shape visual probe decision is recorded: generated, skipped with reason, or already resolved.
5. The north-star mock decision is recorded: generated, skipped with reason, or not applicable.
## Step 0: Project Foundation
PRODUCT.md and `teach` answers do **not** satisfy the shape gate. They are project context only. A compact self-authored brief does not satisfy the shape gate either. `shape=pass` requires a separate user response approving the shape brief or an already-confirmed brief supplied by the user.
Before shape, before code: figure out what kind of project you're working in.
Invalid image-skip reasons include: "the final implementation will be semantic HTML/CSS/SVG", "the diagram should stay editable", "a raster mock would not be used directly", or "the product is fictional." Generated probes and mocks are direction artifacts; they are not implementation assets.
Look at the working directory. Run `ls`. Check for:
## Craft Contract
- An existing framework: `astro.config.mjs/ts`, `next.config.js/ts`, `nuxt.config.ts`, `svelte.config.js`, `vite.config.js/ts`, `package.json` with framework deps, `Cargo.toml` + Leptos/Yew, `Gemfile` + Rails. **If found, use it.** Do not start a parallel build, do not introduce a second framework, do not write to `dist/` or `build/` directly. Whatever pipeline the project has, respect it.
- An existing component library or design system: `src/components/`, `app/components/`, a `tokens.css` / `theme.ts`, an `astro.config` `integrations`. Read what's there before adding to it.
- An existing icon set: `lucide-react`, `@phosphor-icons/react`, `@iconify/*`, hand-rolled SVG sprites in `assets/icons/`. **Use what's already in the project**; don't introduce a second set.
Craft is not a first pass. It is a loop with these required artifacts:
If the directory is empty (greenfield), don't pick a framework silently. Ask the user via the AskUserQuestion tool, with sensible defaults framed by the brief:
1. Confirmed design brief from `shape`.
2. Approved visual direction, from generated probes / mocks when image generation is available.
3. Mock fidelity inventory: the visible ingredients from the approved direction that must survive into code.
4. Semantic, functional implementation using the project's real stack and conventions.
5. Browser evidence across relevant viewports.
6. At least one critique-and-fix pass after the first browser inspection, unless the first pass has no material defects.
```text
What should this be built on?
- Astro (default for content-led brand sites, landing pages, marketing surfaces)
- SvelteKit / Next.js / Nuxt (when the brief implies an app surface or significant interactivity)
- Single index.html (one-shot demo, prototype, or a deliberately framework-free experiment)
```
Do not let generated mockups replace interface structure, copy, accessibility, responsive behavior, or state design. But do treat the approved mock as a concrete visual contract for composition, hierarchy, density, atmosphere, signature motifs, image needs, and distinctive visual moves. "North star" means "preserve the important visible ingredients in semantic code," not "use it as loose mood."
Default: Astro for brand briefs, the project's existing framework for product briefs. Ask once; don't re-ask mid-task.
## Step 1: Shape the Design
Run /impeccable shape, passing along whatever feature description the user provided.
Run /impeccable shape, passing along whatever feature description the user provided. Shape is **required** for craft; it is what produces a confirmed direction.
Wait for the design brief to be fully confirmed by the user before proceeding. The brief is your blueprint, and every implementation decision should trace back to it.
Present the shape output and stop. Wait for the user to confirm, override, or course-correct before writing code.
If this craft run resumed after `teach` created PRODUCT.md, run shape now. Do not treat the teach interview, PRODUCT.md, or a summary of project context as a substitute for shape. Shape is task-specific and must cover scope, content/states, visual direction, constraints, anti-goals, probes when applicable, and explicit brief confirmation.
If the user already supplied a confirmed brief or ran shape separately, use it and skip this step.
If the user has already run /impeccable shape and has a confirmed design brief, skip this step and use the existing brief.
When the original prompt + PRODUCT.md already answer scope, content, and visual direction with no real ambiguity, the shape output can be **compact** (3-5 bullets stating what you're building and the visual lane, ending with one or two specific questions or "confirm or override"). The full 10-section structured brief is reserved for genuinely ambiguous, multi-screen, or stakeholder-heavy tasks. Don't pad a clear brief into a long one to look thorough; equally, don't skip the pause to look efficient.

## Step 3: Land the Visual Direction (Capability-Gated)
Before implementation, generate high-fidelity visual comps when all of these are true:
Generate high-fidelity visual comps before implementation when all three are true:
- The work is **net-new** or visually open-ended enough that composition exploration will improve the build.
- The brief's scope is **mid-fi, high-fi, or production-ready**.
- The current harness has **built-in image generation capability** (for example, Codex with a native image tool). Do **not** ask the user to set up external APIs, shell scripts, or one-off tooling just to do this.
- The work is net-new or visually open-ended enough that composition exploration will improve the build.
- The brief's scope is mid-fi, high-fi, or production-ready.
- The harness gives you native image generation (Codex's `image_gen`, an equivalent MCP tool). Don't ask the user to set up external APIs.
When those conditions are met, this step is mandatory for **both brand and product work** in Codex and any harness with built-in image generation. Use native image generation; in Codex, use the built-in `image_gen` tool via the imagegen skill. If image generation is unavailable, do not ask the user to install APIs or tooling. State in one line that the image step is skipped because the harness lacks native image generation, then proceed.
Do not skip this step because the eventual UI should be semantic, editable, code-native, responsive, or accessible. Those are implementation requirements, not reasons to avoid visual exploration.
### Purpose
Use the mock step to find a stronger visual lane than code-first generation would reliably discover on its own. The brief remains authoritative on user, purpose, content, constraints, states, and anti-goals. The mock clarifies composition, hierarchy, density, typography, and visual tone.
When met, this step is mandatory for both brand and product work. If image generation isn't available, skip silently. "The eventual UI is semantic/code-native/accessible" is not a reason to skip; those are implementation requirements, not exploration ones.
### What to generate
Generate **1 to 3** high-fidelity north-star comps based on the confirmed brief. If shape already produced direction probes, use those results as input and generate a more resolved mock from the winning lane, not another unrelated exploration.
Generate **1 to 3** high-fidelity north-star comps from the confirmed brief. If shape already produced direction probes, resolve the winning lane further, not an unrelated exploration. Comps must differ in primary visual direction, not just color.

- For product work, still push hierarchy, topology, density, and tone, but keep the comps grounded in realistic product structure and states.
- For landing pages and long-form brand surfaces, show enough of the next section or second fold to establish the system beyond the hero.

### Mock fidelity inventory
Before building, inventory the approved mock's major visible ingredients:
Inventory the approved mock's major visible ingredients:
- Hero silhouette and dominant composition.
- Signature motifs: planets, devices, portraits, charts, route lines, insets, badges, or other memorable objects.
- Nav and primary CTA treatment.
- Section sequence visible in the mock, especially the second fold.
- Image-native content the concept depends on.
- Typography, density, color/material treatment, and motion cues.

- Nav and primary CTA treatment
- Section sequence, especially the second fold
- Image-native content the concept depends on
- Typography, density, color/material treatment, motion cues
For each ingredient, decide how it will be implemented: semantic HTML/CSS/SVG, generated asset, sourced project asset, icon library, canvas/WebGL, or an explicitly accepted omission. Do not substitute a different hero composition or new visual driver after approval unless the user approves the change.
For each, decide implementation: semantic HTML/CSS/SVG, generated asset, sourced asset, icon library, canvas/WebGL, or accepted omission. Don't substitute a different hero composition or visual driver post-approval without user sign-off.
Treat the mock as a **north star**, not a screenshot to trace. Do **not** rasterize core UI text or let the mock override the confirmed brief. But if the live result lacks the mock's major visible ingredients, the implementation is wrong.
If a photographic, architectural, product, or place-led mock becomes generic CSS scenery / decorative diagrams / bullets / copy, stop and fix it. That's a broken implementation, not a harmless interpretation.
Treat the mock as a north star, not a screenshot to trace. Don't rasterize core UI text. But if the live result lacks the mock's major ingredients, the implementation is wrong.
## Step 4: Asset Extraction (Need-Gated)
If the chosen direction includes image-native visual ingredients that would materially improve the implementation, generate them as separate assets before building.
If the approved direction needs raster assets, create them before building. Do not replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy.
Good candidates:
Use the native asset producer (`impeccable_asset_producer` in Codex, `impeccable-asset-producer` in Claude Code) to create clean assets from the hi-fi mock and crops. If you do not have explicit permission to use agents, stop and ask:
- stickers
- badges
- seals
- tickets
- graphic labels
- textures
- abstract objects
- decorative marks
- non-semantic scene elements
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
For travel, editorial, portfolio, venue, product showcase, entertainment, education, or any other image-led brand surface, visual assets are usually core content, not decoration. Do not ship abstract CSS panels where the approved mock or subject matter calls for real imagery, generated plates, illustrations, maps, product/object renders, or destination scenes.
Do not skip asset production or silently do it inline. Inline asset production is allowed only if the user declines subagents, the harness cannot spawn the authorized agent, or the user explicitly asks for single-thread mode.
Do **not** export assets for core UI text, navigation, body copy, or any structure that should stay semantic and editable in code.
Pass the approved mock, crop/contact-sheet paths, output directory, dimensions/formats, transparency needs, constraints, and avoid list to the asset producer. Attach image generation capability to the spawned agent when the harness supports it; do not load image-generation reference material into the parent thread first.
Usually **1 to 5** extracted assets is enough. If the design can be built cleanly in HTML/CSS/SVG, prefer that over raster assets. If the mock contains major visual content that cannot be built credibly in code, asset extraction is not optional.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; use real/generated/stock imagery when the mock or subject matter calls for actual visual content.

### Production bar
- Use real or realistic content. Remove placeholder copy, placeholder images, dead links, fake controls, and unused scaffold before presenting.
- Preserve the approved mock's major ingredients. Missing hero objects, missing world/product imagery, different section structure, downgraded CTA/nav treatment, or generic replacements for distinctive motifs are blocking defects unless the user accepted the change.
- Build semantically first: real headings, landmarks, labels, form associations, button/link semantics, accessible names, and state announcements where needed.
- Calibrate spacing, alignment, grid placement, and vertical rhythm deliberately. Do not accept default gaps, arbitrary margins, unbalanced whitespace, or accidental optical misalignment.
- Make typography intentional: chosen font loading strategy, clear hierarchy, readable measure, stable line breaks, tuned wrapping, and no overflow at mobile or large desktop sizes.
- Design realistic state coverage: default, hover where supported, focus-visible, active, disabled, loading, error, success, empty, overflow, long text, short text, and first-run states where relevant.
- Make interaction quality feel finished: keyboard paths, touch targets, feedback timing, scroll behavior, transitions between states, and no hover-only functionality.
- Use icons from the project's established icon set when available. If no set exists, choose a coherent library or use accessible text controls; do not mix unrelated icon styles.
- Optimize imagery and media: correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset` / `picture` for raster assets, and no project-referenced asset left outside the workspace.
- Make motion feel premium: use atmospheric blur, filter, mask, shadow, or reveal effects when they improve the experience; avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- Preserve maintainability: reusable local patterns, clear component boundaries, project conventions, no rasterized UI text, and no hard-coded one-off hacks when a better local pattern exists.
- Fit the technical context: production build passes, no obvious console errors, no avoidable layout shift, no needless dependency, and no broken asset path.
- If you discover a design question that materially changes the brief or approved direction, stop and ask rather than guessing.
- **Real content.** No placeholder copy, placeholder images, dead links, fake controls, or unused scaffold at presentation time.
- **Preserve the approved mock's major ingredients.** Missing hero objects, world/product imagery, section structure, CTA/nav treatment, or distinctive motifs are blocking defects unless the user accepted the change.
- **Semantic first.** Real headings, landmarks, labels, form associations, button/link semantics, accessible names, state announcements where needed.
- **Deliberate spacing and alignment.** No default gaps, arbitrary margins, unbalanced whitespace, or accidental optical misalignment.
- **Intentional typography.** Chosen loading strategy, clear hierarchy, readable measure, stable line breaks, no overflow at any width.
- **Realistic state coverage.** Default, hover, focus-visible, active, disabled, loading, error, success, empty, overflow, long/short text, first-run.
- **Finished interaction quality.** Keyboard paths, touch targets, feedback timing, scroll behavior, state transitions, no hover-only functionality.
- **Coherent icon set.** Use the project's established set; otherwise pick one library or use accessible text. Don't mix.
- **Respect the build pipeline.** Edit source files and run the project's build (`npm run build` or equivalent). Don't write to `build/` / `dist/` / `.next/` with `cat`, heredoc, or Bash redirects; that skips asset hashing, image optimization, code splitting, and CSS extraction, and produces output the dev server won't serve.
- **Verify image URLs before referencing them.** Use image-search MCP or web-fetch when available; guessed photo IDs ship as broken-image placeholders. Without verification, prefer fewer images you're confident about.
- **Optimized imagery and media.** Correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset`/`picture` for raster, no project-referenced asset left outside the workspace.
- **Premium motion.** Use atmospheric blur, filter, mask, shadow, reveal when they improve the experience. Avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- **Maintainable.** Reusable local patterns, clear component boundaries, project conventions. No rasterized UI text or one-off hacks when a local pattern exists.
- **Technically clean.** Production build passes, no console errors, no avoidable layout shift, no needless dependencies, no broken asset paths.
- **Ask when uncertain.** If a discovery materially changes the brief or approved direction, stop and ask. Don't guess.
## Step 6: Browser-Based Iteration
## Step 6: Iterate Visually
**This step is critical.** Do not stop after the first implementation pass.
Look at what you built like a designer would. Your eyes are whatever the harness gives you: a connected browser, a screenshotting tool, Playwright, or asking the user. Use them for responsive testing (mobile, tablet, desktop minimum) and general visual validation.
Open the result in a browser. In Codex, use browser-use or equivalent browser automation when available; otherwise use Playwright or ask the user for screenshots. Inspect screenshots, not just DOM or terminal output.
If your tool returns a file path, read the PNG back into the conversation. A screenshot you didn't read doesn't count.
### Required viewport pass
For long-form brand surfaces, inspect major sections individually. Thumbnails hide spacing, clipping, and cascade defects.
Check the experience at the viewports that matter for the brief. Default minimum:
After the first pass, write an honest critique against the brief, the approved mock's major ingredients (hero silhouette, motifs, imagery, nav/CTA, density), and impeccable's DON'Ts. Patch material defects and re-inspect. **Don't invent defects to demonstrate iteration.** A confident "first pass clean, shipping" beats a fake fix.
- Mobile narrow
- Tablet or small laptop
- Desktop wide
Actively check: responsive behavior (composes, not shrinks), every state (empty / error / loading / edge), craft details (spacing, alignment, hierarchy, contrast, motion timing, focus), performance basics. The exit bar: defensible in a high-end studio review.
For each viewport, capture or inspect the rendered state and look for visual defects: overlap, clipping, weak hierarchy, off-grid alignment, awkward whitespace, cramped controls, unreadable type, broken imagery, hover-only functionality, layout shift, and text overflow.
### Critique and fix loop
After the first browser pass, write a short critique for yourself and patch the implementation. Repeat browser inspection after fixes. Continue until no material issues remain against this checklist:
1. **Does it match the brief?** Compare the live result against every section of the design brief. Fix discrepancies.
2. **Does it match the approved mock?** Compare screenshots against the mock fidelity inventory: hero silhouette, major motifs, imagery, nav/CTA, section sequence, density, color/materials, and second-fold substance. Missing major ingredients are P0 defects.
3. **Does it pass the AI slop test?** If someone saw this and said "AI made this," would they believe it immediately? If yes, it needs more design intention.
4. **Check against impeccable's DON'T guidelines.** Fix any anti-pattern violations.
5. **Check every state.** Navigate through empty, error, loading, and edge case states. Each one should feel intentional, not like an afterthought.
6. **Check responsive behavior.** The design should adapt compositionally, not merely shrink.
7. **Check craft details.** Spacing consistency, optical alignment, type hierarchy, color contrast, image quality, icon coherence, interactive feedback, motion timing, and focus treatment.
8. **Check performance basics.** No obviously oversized images, avoidable layout thrash, blocking animations, or heavy assets without a reason.
The exit bar is not "it works." It is: the rendered result looks intentional at all checked viewports, all expected states are handled, no placeholders remain unless explicitly accepted, and the implementation quality would be defensible in a high-end studio review.

Once confirmed, the brief is complete. The user can now hand it to /impeccable, or use it to guide any other implementation approach. (If the user wants the full discovery-then-build flow in one step, they should use /impeccable craft instead, which runs this command internally.)

1. Load context (PRODUCT.md / DESIGN.md) via the loader script.
2. Identify the register and load the matching register reference (brand.md or product.md).
3. **If the user invoked a sub-command (e.g. `craft`, `shape`, `audit`), load its reference file too.** This is non-negotiable: `craft` without `craft.md` loaded means you'll skip the shape-and-confirm step the user expects.
Codex-style agents must state this before editing files:
```text
IMPECCABLE_PREFLIGHT: context=pass product=pass command_reference=pass shape=pass|not_required image_gate=pass|skipped:<reason> mutation=open
```
For `/impeccable craft`, `shape=pass` is only valid after a separate user response approving the shape design brief, or when the user provided an already-confirmed brief in the request. Do not mark `shape=pass` after writing PRODUCT.md, summarizing assumptions, or drafting an unconfirmed brief yourself.
Other harnesses should follow the same checklist when they can expose this state.

# Craft Flow
Build a feature with impeccable UX and UI quality through a structured process: shape the design, land the visual direction, build real production code, then inspect and improve in-browser until the result meets a high-end studio bar.
Build a feature with impeccable UX and UI quality: shape the design, land the visual direction, build real production code, inspect and improve in-browser until it meets a high-end studio bar.
## Build Gate
Before writing code, you need: PRODUCT.md loaded, register identified and the matching reference loaded, and a confirmed design direction for this task (either from `shape` or supplied by the user). PRODUCT.md is project context, not a task-specific brief.
Craft cannot build until all of these are true:
Treat any approved visual direction (generated mock or stated reference) as a concrete contract for composition, hierarchy, density, atmosphere, signature motifs, and distinctive visual moves. Don't let mocks replace structure, copy, accessibility, or state design. But if the live result lacks the approved direction's major ingredients, the implementation is wrong.
1. PRODUCT context is valid and current.
2. The shape design brief is explicitly confirmed by the user for this task, unless the user already provided a confirmed brief.
3. Implementation references from the brief are loaded.
4. The shape visual probe decision is recorded: generated, skipped with reason, or already resolved.
5. The north-star mock decision is recorded: generated, skipped with reason, or not applicable.
## Step 0: Project Foundation
PRODUCT.md and `teach` answers do **not** satisfy the shape gate. They are project context only. A compact self-authored brief does not satisfy the shape gate either. `shape=pass` requires a separate user response approving the shape brief or an already-confirmed brief supplied by the user.
Before shape, before code: figure out what kind of project you're working in.
Invalid image-skip reasons include: "the final implementation will be semantic HTML/CSS/SVG", "the diagram should stay editable", "a raster mock would not be used directly", or "the product is fictional." Generated probes and mocks are direction artifacts; they are not implementation assets.
Look at the working directory. Run `ls`. Check for:
## Craft Contract
- An existing framework: `astro.config.mjs/ts`, `next.config.js/ts`, `nuxt.config.ts`, `svelte.config.js`, `vite.config.js/ts`, `package.json` with framework deps, `Cargo.toml` + Leptos/Yew, `Gemfile` + Rails. **If found, use it.** Do not start a parallel build, do not introduce a second framework, do not write to `dist/` or `build/` directly. Whatever pipeline the project has, respect it.
- An existing component library or design system: `src/components/`, `app/components/`, a `tokens.css` / `theme.ts`, an `astro.config` `integrations`. Read what's there before adding to it.
- An existing icon set: `lucide-react`, `@phosphor-icons/react`, `@iconify/*`, hand-rolled SVG sprites in `assets/icons/`. **Use what's already in the project**; don't introduce a second set.
Craft is not a first pass. It is a loop with these required artifacts:
If the directory is empty (greenfield), don't pick a framework silently. Ask the user via the AskUserQuestion tool, with sensible defaults framed by the brief:
1. Confirmed design brief from `shape`.
2. Approved visual direction, from generated probes / mocks when image generation is available.
3. Mock fidelity inventory: the visible ingredients from the approved direction that must survive into code.
4. Semantic, functional implementation using the project's real stack and conventions.
5. Browser evidence across relevant viewports.
6. At least one critique-and-fix pass after the first browser inspection, unless the first pass has no material defects.
```text
What should this be built on?
- Astro (default for content-led brand sites, landing pages, marketing surfaces)
- SvelteKit / Next.js / Nuxt (when the brief implies an app surface or significant interactivity)
- Single index.html (one-shot demo, prototype, or a deliberately framework-free experiment)
```
Do not let generated mockups replace interface structure, copy, accessibility, responsive behavior, or state design. But do treat the approved mock as a concrete visual contract for composition, hierarchy, density, atmosphere, signature motifs, image needs, and distinctive visual moves. "North star" means "preserve the important visible ingredients in semantic code," not "use it as loose mood."
Default: Astro for brand briefs, the project's existing framework for product briefs. Ask once; don't re-ask mid-task.
## Step 1: Shape the Design
Run /impeccable shape, passing along whatever feature description the user provided.
Run /impeccable shape, passing along whatever feature description the user provided. Shape is **required** for craft; it is what produces a confirmed direction.
Wait for the design brief to be fully confirmed by the user before proceeding. The brief is your blueprint, and every implementation decision should trace back to it.
Present the shape output and stop. Wait for the user to confirm, override, or course-correct before writing code.
If this craft run resumed after `teach` created PRODUCT.md, run shape now. Do not treat the teach interview, PRODUCT.md, or a summary of project context as a substitute for shape. Shape is task-specific and must cover scope, content/states, visual direction, constraints, anti-goals, probes when applicable, and explicit brief confirmation.
If the user already supplied a confirmed brief or ran shape separately, use it and skip this step.
If the user has already run /impeccable shape and has a confirmed design brief, skip this step and use the existing brief.
When the original prompt + PRODUCT.md already answer scope, content, and visual direction with no real ambiguity, the shape output can be **compact** (3-5 bullets stating what you're building and the visual lane, ending with one or two specific questions or "confirm or override"). The full 10-section structured brief is reserved for genuinely ambiguous, multi-screen, or stakeholder-heavy tasks. Don't pad a clear brief into a long one to look thorough; equally, don't skip the pause to look efficient.

## Step 3: Land the Visual Direction (Capability-Gated)
Before implementation, generate high-fidelity visual comps when all of these are true:
Generate high-fidelity visual comps before implementation when all three are true:
- The work is **net-new** or visually open-ended enough that composition exploration will improve the build.
- The brief's scope is **mid-fi, high-fi, or production-ready**.
- The current harness has **built-in image generation capability** (for example, Codex with a native image tool). Do **not** ask the user to set up external APIs, shell scripts, or one-off tooling just to do this.
- The work is net-new or visually open-ended enough that composition exploration will improve the build.
- The brief's scope is mid-fi, high-fi, or production-ready.
- The harness gives you native image generation (Codex's `image_gen`, an equivalent MCP tool). Don't ask the user to set up external APIs.
When those conditions are met, this step is mandatory for **both brand and product work** in Codex and any harness with built-in image generation. Use native image generation; in Codex, use the built-in `image_gen` tool via the imagegen skill. If image generation is unavailable, do not ask the user to install APIs or tooling. State in one line that the image step is skipped because the harness lacks native image generation, then proceed.
Do not skip this step because the eventual UI should be semantic, editable, code-native, responsive, or accessible. Those are implementation requirements, not reasons to avoid visual exploration.
### Purpose
Use the mock step to find a stronger visual lane than code-first generation would reliably discover on its own. The brief remains authoritative on user, purpose, content, constraints, states, and anti-goals. The mock clarifies composition, hierarchy, density, typography, and visual tone.
When met, this step is mandatory for both brand and product work. If image generation isn't available, skip silently. "The eventual UI is semantic/code-native/accessible" is not a reason to skip; those are implementation requirements, not exploration ones.
### What to generate
Generate **1 to 3** high-fidelity north-star comps based on the confirmed brief. If shape already produced direction probes, use those results as input and generate a more resolved mock from the winning lane, not another unrelated exploration.
Generate **1 to 3** high-fidelity north-star comps from the confirmed brief. If shape already produced direction probes, resolve the winning lane further, not an unrelated exploration. Comps must differ in primary visual direction, not just color.

- For product work, still push hierarchy, topology, density, and tone, but keep the comps grounded in realistic product structure and states.
- For landing pages and long-form brand surfaces, show enough of the next section or second fold to establish the system beyond the hero.

Before building, inventory the approved mock's major visible ingredients:
Inventory the approved mock's major visible ingredients:
- Hero silhouette and dominant composition.
- Signature motifs: planets, devices, portraits, charts, route lines, insets, badges, or other memorable objects.
- Nav and primary CTA treatment.

- Image-native content the concept depends on.
- Typography, density, color/material treatment, and motion cues.

For each ingredient, decide how it will be implemented: semantic HTML/CSS/SVG, generated asset, sourced project asset, icon library, canvas/WebGL, or an explicitly accepted omission. Do not substitute a different hero composition or new visual driver after approval unless the user approves the change.

Treat the mock as a north star, not a screenshot to trace. Don't rasterize core UI text. But if the live result lacks the mock's major ingredients, the implementation is wrong.
## Step 4: Asset Extraction (Need-Gated)
If the chosen direction includes image-native visual ingredients that would materially improve the implementation, generate them as separate assets before building.
If the approved direction needs raster assets, create them before building. Do not replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy.
Good candidates:
Use the native asset producer (`impeccable_asset_producer` in Codex, `impeccable-asset-producer` in Claude Code) to create clean assets from the hi-fi mock and crops. If you do not have explicit permission to use agents, stop and ask:
- stickers
- badges
- seals
- tickets
- graphic labels
- textures
- abstract objects
- decorative marks
- non-semantic scene elements
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
For travel, editorial, portfolio, venue, product showcase, entertainment, education, or any other image-led brand surface, visual assets are usually core content, not decoration. Do not ship abstract CSS panels where the approved mock or subject matter calls for real imagery, generated plates, illustrations, maps, product/object renders, or destination scenes.
Do not skip asset production or silently do it inline. Inline asset production is allowed only if the user declines subagents, the harness cannot spawn the authorized agent, or the user explicitly asks for single-thread mode.
Do **not** export assets for core UI text, navigation, body copy, or any structure that should stay semantic and editable in code.
Pass the approved mock, crop/contact-sheet paths, output directory, dimensions/formats, transparency needs, constraints, and avoid list to the asset producer. Attach image generation capability to the spawned agent when the harness supports it; do not load image-generation reference material into the parent thread first.
Usually **1 to 5** extracted assets is enough. If the design can be built cleanly in HTML/CSS/SVG, prefer that over raster assets. If the mock contains major visual content that cannot be built credibly in code, asset extraction is not optional.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; use real/generated/stock imagery when the mock or subject matter calls for actual visual content.

- Build semantically first: real headings, landmarks, labels, form associations, button/link semantics, accessible names, and state announcements where needed.
- Calibrate spacing, alignment, grid placement, and vertical rhythm deliberately. Do not accept default gaps, arbitrary margins, unbalanced whitespace, or accidental optical misalignment.
- Make typography intentional: chosen font loading strategy, clear hierarchy, readable measure, stable line breaks, tuned wrapping, and no overflow at mobile or large desktop sizes.
- Design realistic state coverage: default, hover where supported, focus-visible, active, disabled, loading, error, success, empty, overflow, long text, short text, and first-run states where relevant.
- Make interaction quality feel finished: keyboard paths, touch targets, feedback timing, scroll behavior, transitions between states, and no hover-only functionality.
- Use icons from the project's established icon set when available. If no set exists, choose a coherent library or use accessible text controls; do not mix unrelated icon styles.
- Optimize imagery and media: correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset` / `picture` for raster assets, and no project-referenced asset left outside the workspace.
- Make motion feel premium: use atmospheric blur, filter, mask, shadow, or reveal effects when they improve the experience; avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- Preserve maintainability: reusable local patterns, clear component boundaries, project conventions, no rasterized UI text, and no hard-coded one-off hacks when a better local pattern exists.

- **Respect the build pipeline.** Edit source files and run the project's build (`npm run build` or equivalent). Don't write to `build/` / `dist/` / `.next/` with `cat`, heredoc, or Bash redirects; that skips asset hashing, image optimization, code splitting, and CSS extraction, and produces output the dev server won't serve.

- **Optimized imagery and media.** Correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset`/`picture` for raster, no project-referenced asset left outside the workspace.
- **Premium motion.** Use atmospheric blur, filter, mask, shadow, reveal when they improve the experience. Avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- **Maintainable.** Reusable local patterns, clear component boundaries, project conventions. No rasterized UI text or one-off hacks when a local pattern exists.

- **Ask when uncertain.** If a discovery materially changes the brief or approved direction, stop and ask. Don't guess.
## Step 6: Browser-Based Iteration
## Step 6: Iterate Visually
**This step is critical.** Do not stop after the first implementation pass.
Look at what you built like a designer would. Your eyes are whatever the harness gives you: a connected browser, a screenshotting tool, Playwright, or asking the user. Use them for responsive testing (mobile, tablet, desktop minimum) and general visual validation.
Open the result in a browser. In Codex, use browser-use or equivalent browser automation when available; otherwise use Playwright or ask the user for screenshots. Inspect screenshots, not just DOM or terminal output.
If your tool returns a file path, read the PNG back into the conversation. A screenshot you didn't read doesn't count.
### Required viewport pass
For long-form brand surfaces, inspect major sections individually. Thumbnails hide spacing, clipping, and cascade defects.
Check the experience at the viewports that matter for the brief. Default minimum:
After the first pass, write an honest critique against the brief, the approved mock's major ingredients (hero silhouette, motifs, imagery, nav/CTA, density), and impeccable's DON'Ts. Patch material defects and re-inspect. **Don't invent defects to demonstrate iteration.** A confident "first pass clean, shipping" beats a fake fix.
- Mobile narrow
- Tablet or small laptop
- Desktop wide
Actively check: responsive behavior (composes, not shrinks), every state (empty / error / loading / edge), craft details (spacing, alignment, hierarchy, contrast, motion timing, focus), performance basics. The exit bar: defensible in a high-end studio review.
For each viewport, capture or inspect the rendered state and look for visual defects: overlap, clipping, weak hierarchy, off-grid alignment, awkward whitespace, cramped controls, unreadable type, broken imagery, hover-only functionality, layout shift, and text overflow.
### Critique and fix loop
After the first browser pass, write a short critique for yourself and patch the implementation. Repeat browser inspection after fixes. Continue until no material issues remain against this checklist:
1. **Does it match the brief?** Compare the live result against every section of the design brief. Fix discrepancies.
2. **Does it match the approved mock?** Compare screenshots against the mock fidelity inventory: hero silhouette, major motifs, imagery, nav/CTA, section sequence, density, color/materials, and second-fold substance. Missing major ingredients are P0 defects.
3. **Does it pass the AI slop test?** If someone saw this and said "AI made this," would they believe it immediately? If yes, it needs more design intention.
4. **Check against impeccable's DON'T guidelines.** Fix any anti-pattern violations.
5. **Check every state.** Navigate through empty, error, loading, and edge case states. Each one should feel intentional, not like an afterthought.
6. **Check responsive behavior.** The design should adapt compositionally, not merely shrink.
7. **Check craft details.** Spacing consistency, optical alignment, type hierarchy, color contrast, image quality, icon coherence, interactive feedback, motion timing, and focus treatment.
8. **Check performance basics.** No obviously oversized images, avoidable layout thrash, blocking animations, or heavy assets without a reason.
The exit bar is not "it works." It is: the rendered result looks intentional at all checked viewports, all expected states are handled, no placeholders remain unless explicitly accepted, and the implementation quality would be defensible in a high-end studio review.

2. **Move the CSS rules** into the project's real stylesheet. Which stylesheet depends on the project (e.g. `public/css/workflow.css` for this repo, or the component's co-located CSS file for a Vite/Next project; pick whichever already owns styling for the surrounding element).

3. **Bake in parameter values while rewriting selectors.** For `@scope ([data-impeccable-variant="N"])` wrappers: retarget to real, semantic classes on the accepted HTML (`.why-visual--v2 .v2-label { … }`). For `:scope[data-p-<id>="VALUE"]` selectors: keep only the branch matching the chosen value from the param-values comment; drop the others (they're dead after accept). For `var(--p-<id>, DEFAULT)` in the CSS: either substitute the literal value, or if the param is still useful as a knob going forward, leave the var and update its initial declaration to the chosen value.
4. **Unwrap the accepted content.** Delete the `<div data-impeccable-variant="N" style="display: contents">` that wraps it. Drop `data-impeccable-params` and any `data-p-*` attributes from it; those are live-mode plumbing, not source.
5. **Delete the inline `<style>` block, the `<!-- impeccable-param-values -->` comment if present, and both `<!-- impeccable-carbonize-start/end -->` markers.** Also drop any `@scope` rules for variants other than the accepted one; those are dead code now.

After the interview and any required probes, present a brief and **end your response**. The user must confirm before any implementation runs. Do not present a brief and then continue to code in the same response, even if the brief feels obvious to you. The user's confirmation is the gate.
**Choose the brief shape based on how clear the answers are:**
- **Compact form (3-5 bullets)** when discovery was crisp and the original prompt + PRODUCT.md already pinned scope, content, and direction. State what you're building, the visual lane, and end with one or two specific questions or a clear "confirm or override?" prompt. This is the default for typical craft requests with a clear prompt.

| Mutation | All active gates above pass. | Do not edit project files yet. |
1. Load context (PRODUCT.md / DESIGN.md) via the loader script.
2. Identify the register and load the matching register reference (brand.md or product.md).
3. **If the user invoked a sub-command (e.g. `craft`, `shape`, `audit`), load its reference file too.** This is non-negotiable: `craft` without `craft.md` loaded means you'll skip the shape-and-confirm step the user expects.
Codex-style agents must state this before editing files:
```text
IMPECCABLE_PREFLIGHT: context=pass product=pass command_reference=pass shape=pass|not_required image_gate=pass|skipped:<reason> mutation=open
```
For `/impeccable craft`, `shape=pass` is only valid after a separate user response approving the shape design brief, or when the user provided an already-confirmed brief in the request. Do not mark `shape=pass` after writing PRODUCT.md, summarizing assumptions, or drafting an unconfirmed brief yourself.

# Craft Flow
Build a feature with impeccable UX and UI quality through a structured process: shape the design, land the visual direction, build real production code, then inspect and improve in-browser until the result meets a high-end studio bar.
Build a feature with impeccable UX and UI quality: shape the design, land the visual direction, build real production code, inspect and improve in-browser until it meets a high-end studio bar.
## Build Gate
Before writing code, you need: PRODUCT.md loaded, register identified and the matching reference loaded, and a confirmed design direction for this task (either from `shape` or supplied by the user). PRODUCT.md is project context, not a task-specific brief.
Craft cannot build until all of these are true:
Treat any approved visual direction (generated mock or stated reference) as a concrete contract for composition, hierarchy, density, atmosphere, signature motifs, and distinctive visual moves. Don't let mocks replace structure, copy, accessibility, or state design. But if the live result lacks the approved direction's major ingredients, the implementation is wrong.
1. PRODUCT context is valid and current.
2. The shape design brief is explicitly confirmed by the user for this task, unless the user already provided a confirmed brief.
3. Implementation references from the brief are loaded.
4. The shape visual probe decision is recorded: generated, skipped with reason, or already resolved.
5. The north-star mock decision is recorded: generated, skipped with reason, or not applicable.
## Step 0: Project Foundation
PRODUCT.md and `teach` answers do **not** satisfy the shape gate. They are project context only. A compact self-authored brief does not satisfy the shape gate either. `shape=pass` requires a separate user response approving the shape brief or an already-confirmed brief supplied by the user.
Before shape, before code: figure out what kind of project you're working in.
Invalid image-skip reasons include: "the final implementation will be semantic HTML/CSS/SVG", "the diagram should stay editable", "a raster mock would not be used directly", or "the product is fictional." Generated probes and mocks are direction artifacts; they are not implementation assets.
Look at the working directory. Run `ls`. Check for:
## Craft Contract
- An existing framework: `astro.config.mjs/ts`, `next.config.js/ts`, `nuxt.config.ts`, `svelte.config.js`, `vite.config.js/ts`, `package.json` with framework deps, `Cargo.toml` + Leptos/Yew, `Gemfile` + Rails. **If found, use it.** Do not start a parallel build, do not introduce a second framework, do not write to `dist/` or `build/` directly. Whatever pipeline the project has, respect it.
- An existing component library or design system: `src/components/`, `app/components/`, a `tokens.css` / `theme.ts`, an `astro.config` `integrations`. Read what's there before adding to it.
- An existing icon set: `lucide-react`, `@phosphor-icons/react`, `@iconify/*`, hand-rolled SVG sprites in `assets/icons/`. **Use what's already in the project**; don't introduce a second set.
Craft is not a first pass. It is a loop with these required artifacts:
If the directory is empty (greenfield), don't pick a framework silently. Ask the user via the AskUserQuestion tool, with sensible defaults framed by the brief:
1. Confirmed design brief from `shape`.
2. Approved visual direction, from generated probes / mocks when image generation is available.
3. Mock fidelity inventory: the visible ingredients from the approved direction that must survive into code.
4. Semantic, functional implementation using the project's real stack and conventions.
5. Browser evidence across relevant viewports.
6. At least one critique-and-fix pass after the first browser inspection, unless the first pass has no material defects.
```text
What should this be built on?
- Astro (default for content-led brand sites, landing pages, marketing surfaces)
- SvelteKit / Next.js / Nuxt (when the brief implies an app surface or significant interactivity)
- Single index.html (one-shot demo, prototype, or a deliberately framework-free experiment)
```
Do not let generated mockups replace interface structure, copy, accessibility, responsive behavior, or state design. But do treat the approved mock as a concrete visual contract for composition, hierarchy, density, atmosphere, signature motifs, image needs, and distinctive visual moves. "North star" means "preserve the important visible ingredients in semantic code," not "use it as loose mood."
Default: Astro for brand briefs, the project's existing framework for product briefs. Ask once; don't re-ask mid-task.
## Step 1: Shape the Design
Run /impeccable shape, passing along whatever feature description the user provided.
Run /impeccable shape, passing along whatever feature description the user provided. Shape is **required** for craft; it is what produces a confirmed direction.
Wait for the design brief to be fully confirmed by the user before proceeding. The brief is your blueprint, and every implementation decision should trace back to it.
Present the shape output and stop. Wait for the user to confirm, override, or course-correct before writing code.
If this craft run resumed after `teach` created PRODUCT.md, run shape now. Do not treat the teach interview, PRODUCT.md, or a summary of project context as a substitute for shape. Shape is task-specific and must cover scope, content/states, visual direction, constraints, anti-goals, probes when applicable, and explicit brief confirmation.
If the user already supplied a confirmed brief or ran shape separately, use it and skip this step.
If the user has already run /impeccable shape and has a confirmed design brief, skip this step and use the existing brief.
When the original prompt + PRODUCT.md already answer scope, content, and visual direction with no real ambiguity, the shape output can be **compact** (3-5 bullets stating what you're building and the visual lane, ending with one or two specific questions or "confirm or override"). The full 10-section structured brief is reserved for genuinely ambiguous, multi-screen, or stakeholder-heavy tasks.

Before implementation, generate high-fidelity visual comps when all of these are true:
Generate high-fidelity visual comps before implementation when all three are true:

When those conditions are met, this step is mandatory for **both brand and product work** in Codex and any harness with built-in image generation. Use native image generation; in Codex, use the built-in `image_gen` tool via the imagegen skill. If image generation is unavailable, do not ask the user to install APIs or tooling. State in one line that the image step is skipped because the harness lacks native image generation, then proceed.
Do not skip this step because the eventual UI should be semantic, editable, code-native, responsive, or accessible. Those are implementation requirements, not reasons to avoid visual exploration.
### Purpose
Use the mock step to find a stronger visual lane than code-first generation would reliably discover on its own. The brief remains authoritative on user, purpose, content, constraints, states, and anti-goals. The mock clarifies composition, hierarchy, density, typography, and visual tone.
When met, this step is mandatory for both brand and product work. If image generation isn't available, skip silently. "The eventual UI is semantic/code-native/accessible" is not a reason to skip; those are implementation requirements, not exploration ones.

Inventory the approved mock's major visible ingredients:
- Hero silhouette and dominant composition.
- Signature motifs: planets, devices, portraits, charts, route lines, insets, badges, or other memorable objects.

- Image-native content the concept depends on.

For each ingredient, decide how it will be implemented: semantic HTML/CSS/SVG, generated asset, sourced project asset, icon library, canvas/WebGL, or an explicitly accepted omission. Do not substitute a different hero composition or new visual driver after approval unless the user approves the change.

- badges
- seals
- tickets
- graphic labels
- textures
- abstract objects
- decorative marks
- non-semantic scene elements
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
For travel, editorial, portfolio, venue, product showcase, entertainment, education, or any other image-led brand surface, visual assets are usually core content, not decoration. Do not ship abstract CSS panels where the approved mock or subject matter calls for real imagery, generated plates, illustrations, maps, product/object renders, or destination scenes.
Do not skip asset production or silently do it inline. Inline asset production is allowed only if the user declines subagents, the harness cannot spawn the authorized agent, or the user explicitly asks for single-thread mode.
Do **not** export assets for core UI text, navigation, body copy, or any structure that should stay semantic and editable in code.
Pass the approved mock, crop/contact-sheet paths, output directory, dimensions/formats, transparency needs, constraints, and avoid list to the asset producer. Attach image generation capability to the spawned agent when the harness supports it; do not load image-generation reference material into the parent thread first.
Usually **1 to 5** extracted assets is enough. If the design can be built cleanly in HTML/CSS/SVG, prefer that over raster assets. If the mock contains major visual content that cannot be built credibly in code, asset extraction is not optional.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; use real/generated/stock imagery when the mock or subject matter calls for actual visual content.

### Production bar
- Use real or realistic content. Remove placeholder copy, placeholder images, dead links, fake controls, and unused scaffold before presenting.
- Preserve the approved mock's major ingredients. Missing hero objects, missing world/product imagery, different section structure, downgraded CTA/nav treatment, or generic replacements for distinctive motifs are blocking defects unless the user accepted the change.
- Build semantically first: real headings, landmarks, labels, form associations, button/link semantics, accessible names, and state announcements where needed.
- Calibrate spacing, alignment, grid placement, and vertical rhythm deliberately. Do not accept default gaps, arbitrary margins, unbalanced whitespace, or accidental optical misalignment.
- Make typography intentional: chosen font loading strategy, clear hierarchy, readable measure, stable line breaks, tuned wrapping, and no overflow at mobile or large desktop sizes.
- Design realistic state coverage: default, hover where supported, focus-visible, active, disabled, loading, error, success, empty, overflow, long text, short text, and first-run states where relevant.
- Make interaction quality feel finished: keyboard paths, touch targets, feedback timing, scroll behavior, transitions between states, and no hover-only functionality.
- Use icons from the project's established icon set when available. If no set exists, choose a coherent library or use accessible text controls; do not mix unrelated icon styles.
- Optimize imagery and media: correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset` / `picture` for raster assets, and no project-referenced asset left outside the workspace.
- Make motion feel premium: use atmospheric blur, filter, mask, shadow, or reveal effects when they improve the experience; avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- Preserve maintainability: reusable local patterns, clear component boundaries, project conventions, no rasterized UI text, and no hard-coded one-off hacks when a better local pattern exists.
- Fit the technical context: production build passes, no obvious console errors, no avoidable layout shift, no needless dependency, and no broken asset path.
- If you discover a design question that materially changes the brief or approved direction, stop and ask rather than guessing.
- **Real content.** No placeholder copy, placeholder images, dead links, fake controls, or unused scaffold at presentation time.
- **Preserve the approved mock's major ingredients.** Missing hero objects, world/product imagery, section structure, CTA/nav treatment, or distinctive motifs are blocking defects unless the user accepted the change.

- **Realistic state coverage.** Default, hover, focus-visible, active, disabled, loading, error, success, empty, overflow, long/short text, first-run.
- **Finished interaction quality.** Keyboard paths, touch targets, feedback timing, scroll behavior, state transitions, no hover-only functionality.
- **Coherent icon set.** Use the project's established set; otherwise pick one library or use accessible text. Don't mix.
- **Respect the build pipeline.** Edit source files and run the project's build (`npm run build` or equivalent). Don't write to `build/` / `dist/` / `.next/` with `cat`, heredoc, or Bash redirects; that skips asset hashing, image optimization, code splitting, and CSS extraction, and produces output the dev server won't serve.
- **Verify image URLs before referencing them.** Use image-search MCP or web-fetch when available; guessed photo IDs ship as broken-image placeholders. Without verification, prefer fewer images you're confident about.
- **Optimized imagery and media.** Correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset`/`picture` for raster, no project-referenced asset left outside the workspace.
- **Premium motion.** Use atmospheric blur, filter, mask, shadow, reveal when they improve the experience. Avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- **Maintainable.** Reusable local patterns, clear component boundaries, project conventions. No rasterized UI text or one-off hacks when a local pattern exists.
- **Technically clean.** Production build passes, no console errors, no avoidable layout shift, no needless dependencies, no broken asset paths.
- **Ask when uncertain.** If a discovery materially changes the brief or approved direction, stop and ask. Don't guess.
## Step 6: Browser-Based Iteration
## Step 6: Iterate Visually
**This step is critical.** Do not stop after the first implementation pass.
Look at what you built like a designer would. Your eyes are whatever the harness gives you: a connected browser, a screenshotting tool, Playwright, or asking the user. Use them for responsive testing (mobile, tablet, desktop minimum) and general visual validation.
Open the result in a browser. In Codex, use browser-use or equivalent browser automation when available; otherwise use Playwright or ask the user for screenshots. Inspect screenshots, not just DOM or terminal output.
If your tool returns a file path, read the PNG back into the conversation. A screenshot you didn't read doesn't count.
### Required viewport pass
For long-form brand surfaces, inspect major sections individually. Thumbnails hide spacing, clipping, and cascade defects.
Check the experience at the viewports that matter for the brief. Default minimum:
After the first pass, write an honest critique against the brief, the approved mock's major ingredients (hero silhouette, motifs, imagery, nav/CTA, density), and impeccable's DON'Ts. Patch material defects and re-inspect. **Don't invent defects to demonstrate iteration.** A confident "first pass clean, shipping" beats a fake fix.
- Mobile narrow
- Tablet or small laptop
- Desktop wide
Actively check: responsive behavior (composes, not shrinks), every state (empty / error / loading / edge), craft details (spacing, alignment, hierarchy, contrast, motion timing, focus), performance basics. The exit bar: defensible in a high-end studio review.
For each viewport, capture or inspect the rendered state and look for visual defects: overlap, clipping, weak hierarchy, off-grid alignment, awkward whitespace, cramped controls, unreadable type, broken imagery, hover-only functionality, layout shift, and text overflow.
### Critique and fix loop
After the first browser pass, write a short critique for yourself and patch the implementation. Repeat browser inspection after fixes. Continue until no material issues remain against this checklist:
1. **Does it match the brief?** Compare the live result against every section of the design brief. Fix discrepancies.
2. **Does it match the approved mock?** Compare screenshots against the mock fidelity inventory: hero silhouette, major motifs, imagery, nav/CTA, section sequence, density, color/materials, and second-fold substance. Missing major ingredients are P0 defects.
3. **Does it pass the AI slop test?** If someone saw this and said "AI made this," would they believe it immediately? If yes, it needs more design intention.
4. **Check against impeccable's DON'T guidelines.** Fix any anti-pattern violations.
5. **Check every state.** Navigate through empty, error, loading, and edge case states. Each one should feel intentional, not like an afterthought.
6. **Check responsive behavior.** The design should adapt compositionally, not merely shrink.
7. **Check craft details.** Spacing consistency, optical alignment, type hierarchy, color contrast, image quality, icon coherence, interactive feedback, motion timing, and focus treatment.
8. **Check performance basics.** No obviously oversized images, avoidable layout thrash, blocking animations, or heavy assets without a reason.
The exit bar is not "it works." It is: the rendered result looks intentional at all checked viewports, all expected states are handled, no placeholders remain unless explicitly accepted, and the implementation quality would be defensible in a high-end studio review.

After the interview and any required probes, present a brief and **end your response**. The user must confirm before any implementation runs. Do not present a brief and then continue to code in the same response, even if the brief feels obvious to you. The user's confirmation is the gate.
**Choose the brief shape based on how clear the answers are:**
- **Compact form (3-5 bullets)** when discovery was crisp and the original prompt + PRODUCT.md already pinned scope, content, and direction. State what you're building, the visual lane, and end with one or two specific questions or a clear "confirm or override?" prompt. This is the default for typical craft requests with a clear prompt.
- **Full structured form (sections below)** when the task is genuinely ambiguous, multi-screen, or when the user asked for shape as a standalone step. Use this when the discipline of structure earns its weight.
Don't pad a clear brief into a long one to look thorough. A 70-line brief restating answers the user just gave is noise, not rigor. Equally, don't skip the confirmation pause to look efficient: the pause is the point.

| Command | The matching command reference is loaded when a sub-command is used. | Load the reference before continuing. |
| Craft | `/impeccable craft` has a user-confirmed shape brief for this task. `teach` / PRODUCT.md never counts as shape. | Run `/impeccable shape` and wait for explicit brief confirmation. |
| Image | Required visual probes / mocks are generated or skipped with a reason. | Resolve the image-generation gate in `shape.md` or `craft.md` before code. |
| Mutation | All active gates above pass. | Do not edit project files yet. |
1. Load context (PRODUCT.md / DESIGN.md) via the loader script.
2. Identify the register and load the matching register reference (brand.md or product.md).
3. **If the user invoked a sub-command (e.g. `craft`, `shape`, `audit`), load its reference file too.** This is non-negotiable: `craft` without `craft.md` loaded means you'll skip the shape-and-confirm step the user expects.
Codex-style agents must state this before editing files:
```text
IMPECCABLE_PREFLIGHT: context=pass product=pass command_reference=pass shape=pass|not_required image_gate=pass|skipped:<reason> mutation=open
```
For `/impeccable craft`, `shape=pass` is only valid after a separate user response approving the shape design brief, or when the user provided an already-confirmed brief in the request. Do not mark `shape=pass` after writing PRODUCT.md, summarizing assumptions, or drafting an unconfirmed brief yourself.
Other harnesses should follow the same checklist when they can expose this state.

Build a feature with impeccable UX and UI quality: shape the design, land the visual direction, build real production code, inspect and improve in-browser until it meets a high-end studio bar.
## Build Gate
Before writing code, you need: PRODUCT.md loaded, register identified and the matching reference loaded, and a confirmed design direction for this task (either from `shape` or supplied by the user). PRODUCT.md is project context, not a task-specific brief.
Craft cannot build until all of these are true:
Treat any approved visual direction (generated mock or stated reference) as a concrete contract for composition, hierarchy, density, atmosphere, signature motifs, and distinctive visual moves. Don't let mocks replace structure, copy, accessibility, or state design. But if the live result lacks the approved direction's major ingredients, the implementation is wrong.
1. PRODUCT context is valid and current.
2. The shape design brief is explicitly confirmed by the user for this task, unless the user already provided a confirmed brief.
3. Implementation references from the brief are loaded.
4. The shape visual probe decision is recorded: generated, skipped with reason, or already resolved.
5. The north-star mock decision is recorded: generated, skipped with reason, or not applicable.

PRODUCT.md and `teach` answers do **not** satisfy the shape gate. They are project context only. A compact self-authored brief does not satisfy the shape gate either. `shape=pass` requires a separate user response approving the shape brief or an already-confirmed brief supplied by the user.
Before shape, before code: figure out what kind of project you're working in.
Invalid image-skip reasons include: "the final implementation will be semantic HTML/CSS/SVG", "the diagram should stay editable", "a raster mock would not be used directly", or "the product is fictional." Generated probes and mocks are direction artifacts; they are not implementation assets.
Look at the working directory. Run `ls`. Check for:
## Craft Contract
- An existing framework: `astro.config.mjs/ts`, `next.config.js/ts`, `nuxt.config.ts`, `svelte.config.js`, `vite.config.js/ts`, `package.json` with framework deps, `Cargo.toml` + Leptos/Yew, `Gemfile` + Rails. **If found, use it.** Do not start a parallel build, do not introduce a second framework, do not write to `dist/` or `build/` directly. Whatever pipeline the project has, respect it.
- An existing component library or design system: `src/components/`, `app/components/`, a `tokens.css` / `theme.ts`, an `astro.config` `integrations`. Read what's there before adding to it.
- An existing icon set: `lucide-react`, `@phosphor-icons/react`, `@iconify/*`, hand-rolled SVG sprites in `assets/icons/`. **Use what's already in the project**; don't introduce a second set.
Craft is not a first pass. It is a loop with these required artifacts:
If the directory is empty (greenfield), don't pick a framework silently. Ask the user via the AskUserQuestion tool, with sensible defaults framed by the brief:
1. Confirmed design brief from `shape`.
2. Approved visual direction, from generated probes / mocks when image generation is available.
3. Mock fidelity inventory: the visible ingredients from the approved direction that must survive into code.
4. Semantic, functional implementation using the project's real stack and conventions.
5. Browser evidence across relevant viewports.
6. At least one critique-and-fix pass after the first browser inspection, unless the first pass has no material defects.
```text
What should this be built on?
- Astro (default for content-led brand sites, landing pages, marketing surfaces)
- SvelteKit / Next.js / Nuxt (when the brief implies an app surface or significant interactivity)
- Single index.html (one-shot demo, prototype, or a deliberately framework-free experiment)
```
Do not let generated mockups replace interface structure, copy, accessibility, responsive behavior, or state design. But do treat the approved mock as a concrete visual contract for composition, hierarchy, density, atmosphere, signature motifs, image needs, and distinctive visual moves. "North star" means "preserve the important visible ingredients in semantic code," not "use it as loose mood."
Default: Astro for brand briefs, the project's existing framework for product briefs. Ask once; don't re-ask mid-task.
## Step 1: Shape the Design
Run /impeccable shape, passing along whatever feature description the user provided.
Run /impeccable shape, passing along whatever feature description the user provided. Shape is **required** for craft; it is what produces a confirmed direction.
Wait for the design brief to be fully confirmed by the user before proceeding. The brief is your blueprint, and every implementation decision should trace back to it.
Present the shape output and stop. Wait for the user to confirm, override, or course-correct before writing code.
If this craft run resumed after `teach` created PRODUCT.md, run shape now. Do not treat the teach interview, PRODUCT.md, or a summary of project context as a substitute for shape. Shape is task-specific and must cover scope, content/states, visual direction, constraints, anti-goals, probes when applicable, and explicit brief confirmation.
If the user already supplied a confirmed brief or ran shape separately, use it and skip this step.
If the user has already run /impeccable shape and has a confirmed design brief, skip this step and use the existing brief.
When the original prompt + PRODUCT.md already answer scope, content, and visual direction with no real ambiguity, the shape output can be **compact** (3-5 bullets stating what you're building and the visual lane, ending with one or two specific questions or "confirm or override"). The full 10-section structured brief is reserved for genuinely ambiguous, multi-screen, or stakeholder-heavy tasks. Don't pad a clear brief into a long one to look thorough; equally, don't skip the pause to look efficient.

## Step 3: Land the Visual Direction (Capability-Gated)
Before implementation, generate high-fidelity visual comps when all of these are true:
Generate high-fidelity visual comps before implementation when all three are true:
- The work is **net-new** or visually open-ended enough that composition exploration will improve the build.
- The brief's scope is **mid-fi, high-fi, or production-ready**.
- The current harness has **built-in image generation capability** (for example, Codex with a native image tool). Do **not** ask the user to set up external APIs, shell scripts, or one-off tooling just to do this.
- The work is net-new or visually open-ended enough that composition exploration will improve the build.
- The brief's scope is mid-fi, high-fi, or production-ready.
- The harness gives you native image generation (Codex's `image_gen`, an equivalent MCP tool). Don't ask the user to set up external APIs.
When those conditions are met, this step is mandatory for **both brand and product work** in Codex and any harness with built-in image generation. Use native image generation; in Codex, use the built-in `image_gen` tool via the imagegen skill. If image generation is unavailable, do not ask the user to install APIs or tooling. State in one line that the image step is skipped because the harness lacks native image generation, then proceed.
Do not skip this step because the eventual UI should be semantic, editable, code-native, responsive, or accessible. Those are implementation requirements, not reasons to avoid visual exploration.
### Purpose
Use the mock step to find a stronger visual lane than code-first generation would reliably discover on its own. The brief remains authoritative on user, purpose, content, constraints, states, and anti-goals. The mock clarifies composition, hierarchy, density, typography, and visual tone.
When met, this step is mandatory for both brand and product work. If image generation isn't available, skip silently. "The eventual UI is semantic/code-native/accessible" is not a reason to skip; those are implementation requirements, not exploration ones.
### What to generate
Generate **1 to 3** high-fidelity north-star comps based on the confirmed brief. If shape already produced direction probes, use those results as input and generate a more resolved mock from the winning lane, not another unrelated exploration.
Generate **1 to 3** high-fidelity north-star comps from the confirmed brief. If shape already produced direction probes, resolve the winning lane further, not an unrelated exploration. Comps must differ in primary visual direction, not just color.

- For product work, still push hierarchy, topology, density, and tone, but keep the comps grounded in realistic product structure and states.
- For landing pages and long-form brand surfaces, show enough of the next section or second fold to establish the system beyond the hero.

### Mock fidelity inventory
Before building, inventory the approved mock's major visible ingredients:
Inventory the approved mock's major visible ingredients:
- Hero silhouette and dominant composition.
- Signature motifs: planets, devices, portraits, charts, route lines, insets, badges, or other memorable objects.
- Nav and primary CTA treatment.
- Section sequence visible in the mock, especially the second fold.
- Image-native content the concept depends on.
- Typography, density, color/material treatment, and motion cues.

- Nav and primary CTA treatment

- Image-native content the concept depends on
- Typography, density, color/material treatment, motion cues
For each ingredient, decide how it will be implemented: semantic HTML/CSS/SVG, generated asset, sourced project asset, icon library, canvas/WebGL, or an explicitly accepted omission. Do not substitute a different hero composition or new visual driver after approval unless the user approves the change.
For each, decide implementation: semantic HTML/CSS/SVG, generated asset, sourced asset, icon library, canvas/WebGL, or accepted omission. Don't substitute a different hero composition or visual driver post-approval without user sign-off.
Treat the mock as a **north star**, not a screenshot to trace. Do **not** rasterize core UI text or let the mock override the confirmed brief. But if the live result lacks the mock's major visible ingredients, the implementation is wrong.
If a photographic, architectural, product, or place-led mock becomes generic CSS scenery / decorative diagrams / bullets / copy, stop and fix it. That's a broken implementation, not a harmless interpretation.
Treat the mock as a north star, not a screenshot to trace. Don't rasterize core UI text. But if the live result lacks the mock's major ingredients, the implementation is wrong.
## Step 4: Asset Extraction (Need-Gated)
If the chosen direction includes image-native visual ingredients that would materially improve the implementation, generate them as separate assets before building.
If the approved direction needs raster assets, create them before building. Do not replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy.
Good candidates:
Use the native asset producer (`impeccable_asset_producer` in Codex, `impeccable-asset-producer` in Claude Code) to create clean assets from the hi-fi mock and crops. If you do not have explicit permission to use agents, stop and ask:
- stickers
- badges
- seals
- tickets
- graphic labels
- textures
- abstract objects
- decorative marks
- non-semantic scene elements
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
For travel, editorial, portfolio, venue, product showcase, entertainment, education, or any other image-led brand surface, visual assets are usually core content, not decoration. Do not ship abstract CSS panels where the approved mock or subject matter calls for real imagery, generated plates, illustrations, maps, product/object renders, or destination scenes.
Do not skip asset production or silently do it inline. Inline asset production is allowed only if the user declines subagents, the harness cannot spawn the authorized agent, or the user explicitly asks for single-thread mode.
Do **not** export assets for core UI text, navigation, body copy, or any structure that should stay semantic and editable in code.
Pass the approved mock, crop/contact-sheet paths, output directory, dimensions/formats, transparency needs, constraints, and avoid list to the asset producer. Attach image generation capability to the spawned agent when the harness supports it; do not load image-generation reference material into the parent thread first.
Usually **1 to 5** extracted assets is enough. If the design can be built cleanly in HTML/CSS/SVG, prefer that over raster assets. If the mock contains major visual content that cannot be built credibly in code, asset extraction is not optional.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; use real/generated/stock imagery when the mock or subject matter calls for actual visual content.

### Production bar
- Use real or realistic content. Remove placeholder copy, placeholder images, dead links, fake controls, and unused scaffold before presenting.
- Preserve the approved mock's major ingredients. Missing hero objects, missing world/product imagery, different section structure, downgraded CTA/nav treatment, or generic replacements for distinctive motifs are blocking defects unless the user accepted the change.
- Build semantically first: real headings, landmarks, labels, form associations, button/link semantics, accessible names, and state announcements where needed.
- Calibrate spacing, alignment, grid placement, and vertical rhythm deliberately. Do not accept default gaps, arbitrary margins, unbalanced whitespace, or accidental optical misalignment.
- Make typography intentional: chosen font loading strategy, clear hierarchy, readable measure, stable line breaks, tuned wrapping, and no overflow at mobile or large desktop sizes.
- Design realistic state coverage: default, hover where supported, focus-visible, active, disabled, loading, error, success, empty, overflow, long text, short text, and first-run states where relevant.
- Make interaction quality feel finished: keyboard paths, touch targets, feedback timing, scroll behavior, transitions between states, and no hover-only functionality.
- Use icons from the project's established icon set when available. If no set exists, choose a coherent library or use accessible text controls; do not mix unrelated icon styles.
- Optimize imagery and media: correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset` / `picture` for raster assets, and no project-referenced asset left outside the workspace.
- Make motion feel premium: use atmospheric blur, filter, mask, shadow, or reveal effects when they improve the experience; avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- Preserve maintainability: reusable local patterns, clear component boundaries, project conventions, no rasterized UI text, and no hard-coded one-off hacks when a better local pattern exists.
- Fit the technical context: production build passes, no obvious console errors, no avoidable layout shift, no needless dependency, and no broken asset path.
- If you discover a design question that materially changes the brief or approved direction, stop and ask rather than guessing.
- **Real content.** No placeholder copy, placeholder images, dead links, fake controls, or unused scaffold at presentation time.

- **Semantic first.** Real headings, landmarks, labels, form associations, button/link semantics, accessible names, state announcements where needed.
- **Deliberate spacing and alignment.** No default gaps, arbitrary margins, unbalanced whitespace, or accidental optical misalignment.

- **Realistic state coverage.** Default, hover, focus-visible, active, disabled, loading, error, success, empty, overflow, long/short text, first-run.
- **Finished interaction quality.** Keyboard paths, touch targets, feedback timing, scroll behavior, state transitions, no hover-only functionality.
- **Coherent icon set.** Use the project's established set; otherwise pick one library or use accessible text. Don't mix.
- **Respect the build pipeline.** Edit source files and run the project's build (`npm run build` or equivalent). Don't write to `build/` / `dist/` / `.next/` with `cat`, heredoc, or Bash redirects; that skips asset hashing, image optimization, code splitting, and CSS extraction, and produces output the dev server won't serve.
- **Verify image URLs before referencing them.** Use image-search MCP or web-fetch when available; guessed photo IDs ship as broken-image placeholders. Without verification, prefer fewer images you're confident about.
- **Optimized imagery and media.** Correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset`/`picture` for raster, no project-referenced asset left outside the workspace.
- **Premium motion.** Use atmospheric blur, filter, mask, shadow, reveal when they improve the experience. Avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- **Maintainable.** Reusable local patterns, clear component boundaries, project conventions. No rasterized UI text or one-off hacks when a local pattern exists.
- **Technically clean.** Production build passes, no console errors, no avoidable layout shift, no needless dependencies, no broken asset paths.
- **Ask when uncertain.** If a discovery materially changes the brief or approved direction, stop and ask. Don't guess.
## Step 6: Browser-Based Iteration
## Step 6: Iterate Visually
**This step is critical.** Do not stop after the first implementation pass.
Look at what you built like a designer would. Your eyes are whatever the harness gives you: a connected browser, a screenshotting tool, Playwright, or asking the user. Use them for responsive testing (mobile, tablet, desktop minimum) and general visual validation.
Open the result in a browser. In Codex, use browser-use or equivalent browser automation when available; otherwise use Playwright or ask the user for screenshots. Inspect screenshots, not just DOM or terminal output.
If your tool returns a file path, read the PNG back into the conversation. A screenshot you didn't read doesn't count.
### Required viewport pass
For long-form brand surfaces, inspect major sections individually. Thumbnails hide spacing, clipping, and cascade defects.
Check the experience at the viewports that matter for the brief. Default minimum:
After the first pass, write an honest critique against the brief, the approved mock's major ingredients (hero silhouette, motifs, imagery, nav/CTA, density), and impeccable's DON'Ts. Patch material defects and re-inspect. **Don't invent defects to demonstrate iteration.** A confident "first pass clean, shipping" beats a fake fix.
- Mobile narrow
- Tablet or small laptop
- Desktop wide
Actively check: responsive behavior (composes, not shrinks), every state (empty / error / loading / edge), craft details (spacing, alignment, hierarchy, contrast, motion timing, focus), performance basics. The exit bar: defensible in a high-end studio review.
For each viewport, capture or inspect the rendered state and look for visual defects: overlap, clipping, weak hierarchy, off-grid alignment, awkward whitespace, cramped controls, unreadable type, broken imagery, hover-only functionality, layout shift, and text overflow.
### Critique and fix loop
After the first browser pass, write a short critique for yourself and patch the implementation. Repeat browser inspection after fixes. Continue until no material issues remain against this checklist:
1. **Does it match the brief?** Compare the live result against every section of the design brief. Fix discrepancies.
2. **Does it match the approved mock?** Compare screenshots against the mock fidelity inventory: hero silhouette, major motifs, imagery, nav/CTA, section sequence, density, color/materials, and second-fold substance. Missing major ingredients are P0 defects.
3. **Does it pass the AI slop test?** If someone saw this and said "AI made this," would they believe it immediately? If yes, it needs more design intention.
4. **Check against impeccable's DON'T guidelines.** Fix any anti-pattern violations.
5. **Check every state.** Navigate through empty, error, loading, and edge case states. Each one should feel intentional, not like an afterthought.
6. **Check responsive behavior.** The design should adapt compositionally, not merely shrink.
7. **Check craft details.** Spacing consistency, optical alignment, type hierarchy, color contrast, image quality, icon coherence, interactive feedback, motion timing, and focus treatment.
8. **Check performance basics.** No obviously oversized images, avoidable layout thrash, blocking animations, or heavy assets without a reason.
The exit bar is not "it works." It is: the rendered result looks intentional at all checked viewports, all expected states are handled, no placeholders remain unless explicitly accepted, and the implementation quality would be defensible in a high-end studio review.

- **Compact form (3-5 bullets)** when discovery was crisp and the original prompt + PRODUCT.md already pinned scope, content, and direction. State what you're building, the visual lane, and end with one or two specific questions or a clear "confirm or override?" prompt. This is the default for typical craft requests with a clear prompt.

Before any design work or file edits, pass these gates. Skipping them produces generic output that ignores the project.
Before any design work or file edits:
| Gate | Required check | If fail |
|---|---|---|
| Context | The PRODUCT.md / DESIGN.md loader result is known from `node .trae/skills/impeccable/scripts/load-context.mjs`. | Run the loader before continuing. |
| Product | PRODUCT.md exists and is not empty or placeholder (`[TODO]` markers, <200 chars). | Run `/impeccable teach`, refresh context, then resume. Never synthesize PRODUCT.md from the user's original prompt alone. |
| Command | The matching command reference is loaded when a sub-command is used. | Load the reference before continuing. |
| Craft | `/impeccable craft` has a user-confirmed shape brief for this task. `teach` / PRODUCT.md never counts as shape. | Run `/impeccable shape` and wait for explicit brief confirmation. |
| Image | Required visual probes / mocks are generated or skipped with a reason. | Resolve the image-generation gate in `shape.md` or `craft.md` before code. |
| Mutation | All active gates above pass. | Do not edit project files yet. |
1. Load context (PRODUCT.md / DESIGN.md) via the loader script.
2. Identify the register and load the matching register reference (brand.md or product.md).
3. **If the user invoked a sub-command (e.g. `craft`, `shape`, `audit`), load its reference file too.** This is non-negotiable: `craft` without `craft.md` loaded means you'll skip the shape-and-confirm step the user expects.
Codex-style agents must state this before editing files:
```text
IMPECCABLE_PREFLIGHT: context=pass product=pass command_reference=pass shape=pass|not_required image_gate=pass|skipped:<reason> mutation=open
```
For `/impeccable craft`, `shape=pass` is only valid after a separate user response approving the shape design brief, or when the user provided an already-confirmed brief in the request. Do not mark `shape=pass` after writing PRODUCT.md, summarizing assumptions, or drafting an unconfirmed brief yourself.
Other harnesses should follow the same checklist when they can expose this state.
Skipping these produces generic output that ignores the project.

# Craft Flow
Build a feature with impeccable UX and UI quality through a structured process: shape the design, land the visual direction, build real production code, then inspect and improve in-browser until the result meets a high-end studio bar.
Build a feature with impeccable UX and UI quality: shape the design, land the visual direction, build real production code, inspect and improve in-browser until it meets a high-end studio bar.
## Build Gate
Before writing code, you need: PRODUCT.md loaded, register identified and the matching reference loaded, and a confirmed design direction for this task (either from `shape` or supplied by the user). PRODUCT.md is project context, not a task-specific brief.
Craft cannot build until all of these are true:
Treat any approved visual direction (generated mock or stated reference) as a concrete contract for composition, hierarchy, density, atmosphere, signature motifs, and distinctive visual moves. Don't let mocks replace structure, copy, accessibility, or state design. But if the live result lacks the approved direction's major ingredients, the implementation is wrong.
1. PRODUCT context is valid and current.
2. The shape design brief is explicitly confirmed by the user for this task, unless the user already provided a confirmed brief.
3. Implementation references from the brief are loaded.
4. The shape visual probe decision is recorded: generated, skipped with reason, or already resolved.
5. The north-star mock decision is recorded: generated, skipped with reason, or not applicable.
## Step 0: Project Foundation
PRODUCT.md and `teach` answers do **not** satisfy the shape gate. They are project context only. A compact self-authored brief does not satisfy the shape gate either. `shape=pass` requires a separate user response approving the shape brief or an already-confirmed brief supplied by the user.
Before shape, before code: figure out what kind of project you're working in.
Invalid image-skip reasons include: "the final implementation will be semantic HTML/CSS/SVG", "the diagram should stay editable", "a raster mock would not be used directly", or "the product is fictional." Generated probes and mocks are direction artifacts; they are not implementation assets.
Look at the working directory. Run `ls`. Check for:
## Craft Contract
- An existing framework: `astro.config.mjs/ts`, `next.config.js/ts`, `nuxt.config.ts`, `svelte.config.js`, `vite.config.js/ts`, `package.json` with framework deps, `Cargo.toml` + Leptos/Yew, `Gemfile` + Rails. **If found, use it.** Do not start a parallel build, do not introduce a second framework, do not write to `dist/` or `build/` directly. Whatever pipeline the project has, respect it.
- An existing component library or design system: `src/components/`, `app/components/`, a `tokens.css` / `theme.ts`, an `astro.config` `integrations`. Read what's there before adding to it.
- An existing icon set: `lucide-react`, `@phosphor-icons/react`, `@iconify/*`, hand-rolled SVG sprites in `assets/icons/`. **Use what's already in the project**; don't introduce a second set.
Craft is not a first pass. It is a loop with these required artifacts:
If the directory is empty (greenfield), don't pick a framework silently. Ask the user via the AskUserQuestion tool, with sensible defaults framed by the brief:
1. Confirmed design brief from `shape`.
2. Approved visual direction, from generated probes / mocks when image generation is available.
3. Mock fidelity inventory: the visible ingredients from the approved direction that must survive into code.
4. Semantic, functional implementation using the project's real stack and conventions.
5. Browser evidence across relevant viewports.
6. At least one critique-and-fix pass after the first browser inspection, unless the first pass has no material defects.
```text
What should this be built on?
- Astro (default for content-led brand sites, landing pages, marketing surfaces)
- SvelteKit / Next.js / Nuxt (when the brief implies an app surface or significant interactivity)
- Single index.html (one-shot demo, prototype, or a deliberately framework-free experiment)
```
Do not let generated mockups replace interface structure, copy, accessibility, responsive behavior, or state design. But do treat the approved mock as a concrete visual contract for composition, hierarchy, density, atmosphere, signature motifs, image needs, and distinctive visual moves. "North star" means "preserve the important visible ingredients in semantic code," not "use it as loose mood."
Default: Astro for brand briefs, the project's existing framework for product briefs. Ask once; don't re-ask mid-task.
## Step 1: Shape the Design
Run /impeccable shape, passing along whatever feature description the user provided.
Run /impeccable shape, passing along whatever feature description the user provided. Shape is **required** for craft; it is what produces a confirmed direction.
Wait for the design brief to be fully confirmed by the user before proceeding. The brief is your blueprint, and every implementation decision should trace back to it.
Present the shape output and stop. Wait for the user to confirm, override, or course-correct before writing code.
If this craft run resumed after `teach` created PRODUCT.md, run shape now. Do not treat the teach interview, PRODUCT.md, or a summary of project context as a substitute for shape. Shape is task-specific and must cover scope, content/states, visual direction, constraints, anti-goals, probes when applicable, and explicit brief confirmation.
If the user already supplied a confirmed brief or ran shape separately, use it and skip this step.
If the user has already run /impeccable shape and has a confirmed design brief, skip this step and use the existing brief.
When the original prompt + PRODUCT.md already answer scope, content, and visual direction with no real ambiguity, the shape output can be **compact** (3-5 bullets stating what you're building and the visual lane, ending with one or two specific questions or "confirm or override"). The full 10-section structured brief is reserved for genuinely ambiguous, multi-screen, or stakeholder-heavy tasks. Don't pad a clear brief into a long one to look thorough; equally, don't skip the pause to look efficient.

## Step 3: Land the Visual Direction (Capability-Gated)
Before implementation, generate high-fidelity visual comps when all of these are true:
Generate high-fidelity visual comps before implementation when all three are true:
- The work is **net-new** or visually open-ended enough that composition exploration will improve the build.
- The brief's scope is **mid-fi, high-fi, or production-ready**.
- The current harness has **built-in image generation capability** (for example, Codex with a native image tool). Do **not** ask the user to set up external APIs, shell scripts, or one-off tooling just to do this.
- The work is net-new or visually open-ended enough that composition exploration will improve the build.
- The brief's scope is mid-fi, high-fi, or production-ready.
- The harness gives you native image generation (Codex's `image_gen`, an equivalent MCP tool). Don't ask the user to set up external APIs.
When those conditions are met, this step is mandatory for **both brand and product work** in Codex and any harness with built-in image generation. Use native image generation; in Codex, use the built-in `image_gen` tool via the imagegen skill. If image generation is unavailable, do not ask the user to install APIs or tooling. State in one line that the image step is skipped because the harness lacks native image generation, then proceed.
Do not skip this step because the eventual UI should be semantic, editable, code-native, responsive, or accessible. Those are implementation requirements, not reasons to avoid visual exploration.
### Purpose
Use the mock step to find a stronger visual lane than code-first generation would reliably discover on its own. The brief remains authoritative on user, purpose, content, constraints, states, and anti-goals. The mock clarifies composition, hierarchy, density, typography, and visual tone.
When met, this step is mandatory for both brand and product work. If image generation isn't available, skip silently. "The eventual UI is semantic/code-native/accessible" is not a reason to skip; those are implementation requirements, not exploration ones.
### What to generate
Generate **1 to 3** high-fidelity north-star comps based on the confirmed brief. If shape already produced direction probes, use those results as input and generate a more resolved mock from the winning lane, not another unrelated exploration.
Generate **1 to 3** high-fidelity north-star comps from the confirmed brief. If shape already produced direction probes, resolve the winning lane further, not an unrelated exploration. Comps must differ in primary visual direction, not just color.

- For product work, still push hierarchy, topology, density, and tone, but keep the comps grounded in realistic product structure and states.
- For landing pages and long-form brand surfaces, show enough of the next section or second fold to establish the system beyond the hero.

### Mock fidelity inventory
Before building, inventory the approved mock's major visible ingredients:
Inventory the approved mock's major visible ingredients:
- Hero silhouette and dominant composition.
- Signature motifs: planets, devices, portraits, charts, route lines, insets, badges, or other memorable objects.
- Nav and primary CTA treatment.

- Image-native content the concept depends on.
- Typography, density, color/material treatment, and motion cues.

For each ingredient, decide how it will be implemented: semantic HTML/CSS/SVG, generated asset, sourced project asset, icon library, canvas/WebGL, or an explicitly accepted omission. Do not substitute a different hero composition or new visual driver after approval unless the user approves the change.

Treat the mock as a north star, not a screenshot to trace. Don't rasterize core UI text. But if the live result lacks the mock's major ingredients, the implementation is wrong.
## Step 4: Asset Extraction (Need-Gated)
If the chosen direction includes image-native visual ingredients that would materially improve the implementation, generate them as separate assets before building.
If the approved direction needs raster assets, create them before building. Do not replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy.
Good candidates:
Use the native asset producer (`impeccable_asset_producer` in Codex, `impeccable-asset-producer` in Claude Code) to create clean assets from the hi-fi mock and crops. If you do not have explicit permission to use agents, stop and ask:
- stickers
- badges
- seals
- tickets
- graphic labels
- textures
- abstract objects
- decorative marks
- non-semantic scene elements
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
For travel, editorial, portfolio, venue, product showcase, entertainment, education, or any other image-led brand surface, visual assets are usually core content, not decoration. Do not ship abstract CSS panels where the approved mock or subject matter calls for real imagery, generated plates, illustrations, maps, product/object renders, or destination scenes.
Do not skip asset production or silently do it inline. Inline asset production is allowed only if the user declines subagents, the harness cannot spawn the authorized agent, or the user explicitly asks for single-thread mode.
Do **not** export assets for core UI text, navigation, body copy, or any structure that should stay semantic and editable in code.
Pass the approved mock, crop/contact-sheet paths, output directory, dimensions/formats, transparency needs, constraints, and avoid list to the asset producer. Attach image generation capability to the spawned agent when the harness supports it; do not load image-generation reference material into the parent thread first.
Usually **1 to 5** extracted assets is enough. If the design can be built cleanly in HTML/CSS/SVG, prefer that over raster assets. If the mock contains major visual content that cannot be built credibly in code, asset extraction is not optional.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; use real/generated/stock imagery when the mock or subject matter calls for actual visual content.

- Preserve the approved mock's major ingredients. Missing hero objects, missing world/product imagery, different section structure, downgraded CTA/nav treatment, or generic replacements for distinctive motifs are blocking defects unless the user accepted the change.
- Build semantically first: real headings, landmarks, labels, form associations, button/link semantics, accessible names, and state announcements where needed.
- Calibrate spacing, alignment, grid placement, and vertical rhythm deliberately. Do not accept default gaps, arbitrary margins, unbalanced whitespace, or accidental optical misalignment.
- Make typography intentional: chosen font loading strategy, clear hierarchy, readable measure, stable line breaks, tuned wrapping, and no overflow at mobile or large desktop sizes.
- Design realistic state coverage: default, hover where supported, focus-visible, active, disabled, loading, error, success, empty, overflow, long text, short text, and first-run states where relevant.
- Make interaction quality feel finished: keyboard paths, touch targets, feedback timing, scroll behavior, transitions between states, and no hover-only functionality.
- Use icons from the project's established icon set when available. If no set exists, choose a coherent library or use accessible text controls; do not mix unrelated icon styles.
- Optimize imagery and media: correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset` / `picture` for raster assets, and no project-referenced asset left outside the workspace.
- Make motion feel premium: use atmospheric blur, filter, mask, shadow, or reveal effects when they improve the experience; avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- Preserve maintainability: reusable local patterns, clear component boundaries, project conventions, no rasterized UI text, and no hard-coded one-off hacks when a better local pattern exists.
- Fit the technical context: production build passes, no obvious console errors, no avoidable layout shift, no needless dependency, and no broken asset path.

- **Realistic state coverage.** Default, hover, focus-visible, active, disabled, loading, error, success, empty, overflow, long/short text, first-run.
- **Finished interaction quality.** Keyboard paths, touch targets, feedback timing, scroll behavior, state transitions, no hover-only functionality.
- **Coherent icon set.** Use the project's established set; otherwise pick one library or use accessible text. Don't mix.
- **Respect the build pipeline.** Edit source files and run the project's build (`npm run build` or equivalent). Don't write to `build/` / `dist/` / `.next/` with `cat`, heredoc, or Bash redirects; that skips asset hashing, image optimization, code splitting, and CSS extraction, and produces output the dev server won't serve.
- **Verify image URLs before referencing them.** Use image-search MCP or web-fetch when available; guessed photo IDs ship as broken-image placeholders. Without verification, prefer fewer images you're confident about.
- **Optimized imagery and media.** Correct dimensions, useful alt text, lazy loading below the fold, modern formats when practical, responsive `srcset`/`picture` for raster, no project-referenced asset left outside the workspace.
- **Premium motion.** Use atmospheric blur, filter, mask, shadow, reveal when they improve the experience. Avoid casual layout-property animation, bound expensive effects, verify smoothness in-browser, respect reduced motion, and avoid choreography that blocks task completion.
- **Maintainable.** Reusable local patterns, clear component boundaries, project conventions. No rasterized UI text or one-off hacks when a local pattern exists.
- **Technically clean.** Production build passes, no console errors, no avoidable layout shift, no needless dependencies, no broken asset paths.
- **Ask when uncertain.** If a discovery materially changes the brief or approved direction, stop and ask. Don't guess.
## Step 6: Browser-Based Iteration
## Step 6: Iterate Visually
**This step is critical.** Do not stop after the first implementation pass.
Look at what you built like a designer would. Your eyes are whatever the harness gives you: a connected browser, a screenshotting tool, Playwright, or asking the user. Use them for responsive testing (mobile, tablet, desktop minimum) and general visual validation.
Open the result in a browser. In Codex, use browser-use or equivalent browser automation when available; otherwise use Playwright or ask the user for screenshots. Inspect screenshots, not just DOM or terminal output.
If your tool returns a file path, read the PNG back into the conversation. A screenshot you didn't read doesn't count.
### Required viewport pass
For long-form brand surfaces, inspect major sections individually. Thumbnails hide spacing, clipping, and cascade defects.
Check the experience at the viewports that matter for the brief. Default minimum:
After the first pass, write an honest critique against the brief, the approved mock's major ingredients (hero silhouette, motifs, imagery, nav/CTA, density), and impeccable's DON'Ts. Patch material defects and re-inspect. **Don't invent defects to demonstrate iteration.** A confident "first pass clean, shipping" beats a fake fix.
- Mobile narrow
- Tablet or small laptop
- Desktop wide
Actively check: responsive behavior (composes, not shrinks), every state (empty / error / loading / edge), craft details (spacing, alignment, hierarchy, contrast, motion timing, focus), performance basics. The exit bar: defensible in a high-end studio review.
For each viewport, capture or inspect the rendered state and look for visual defects: overlap, clipping, weak hierarchy, off-grid alignment, awkward whitespace, cramped controls, unreadable type, broken imagery, hover-only functionality, layout shift, and text overflow.
### Critique and fix loop
After the first browser pass, write a short critique for yourself and patch the implementation. Repeat browser inspection after fixes. Continue until no material issues remain against this checklist:
1. **Does it match the brief?** Compare the live result against every section of the design brief. Fix discrepancies.
2. **Does it match the approved mock?** Compare screenshots against the mock fidelity inventory: hero silhouette, major motifs, imagery, nav/CTA, section sequence, density, color/materials, and second-fold substance. Missing major ingredients are P0 defects.
3. **Does it pass the AI slop test?** If someone saw this and said "AI made this," would they believe it immediately? If yes, it needs more design intention.
4. **Check against impeccable's DON'T guidelines.** Fix any anti-pattern violations.
5. **Check every state.** Navigate through empty, error, loading, and edge case states. Each one should feel intentional, not like an afterthought.
6. **Check responsive behavior.** The design should adapt compositionally, not merely shrink.
7. **Check craft details.** Spacing consistency, optical alignment, type hierarchy, color contrast, image quality, icon coherence, interactive feedback, motion timing, and focus treatment.
8. **Check performance basics.** No obviously oversized images, avoidable layout thrash, blocking animations, or heavy assets without a reason.
The exit bar is not "it works." It is: the rendered result looks intentional at all checked viewports, all expected states are handled, no placeholders remain unless explicitly accepted, and the implementation quality would be defensible in a high-end studio review.

It's bracketed by `<!-- impeccable-carbonize-start SESSION_ID -->` and `<!-- impeccable-carbonize-end SESSION_ID -->` and contains a `<style data-impeccable-css="SESSION_ID">` element. If the variant declared parameters, an `<!-- impeccable-param-values SESSION_ID: {...} -->` comment sits alongside the style tag with the user's chosen values; read it first; it drives steps 3 and 4 below.
2. **Move the CSS rules** into the project's real stylesheet. Which stylesheet depends on the project (e.g. `public/css/workflow.css` for this repo, or the component's co-located CSS file for a Vite/Next project; pick whichever already owns styling for the surrounding element).
2. **Move the CSS rules** into the project's real stylesheet. Which stylesheet depends on the project (e.g. `site/styles/workflow.css` for an Astro project, or the component's co-located CSS file for a Vite/Next project; pick whichever already owns styling for the surrounding element).
3. **Bake in parameter values while rewriting selectors.** For `@scope ([data-impeccable-variant="N"])` wrappers: retarget to real, semantic classes on the accepted HTML (`.why-visual--v2 .v2-label { … }`). For `:scope[data-p-<id>="VALUE"]` selectors: keep only the branch matching the chosen value from the param-values comment; drop the others (they're dead after accept). For `var(--p-<id>, DEFAULT)` in the CSS: either substitute the literal value, or if the param is still useful as a knob going forward, leave the var and update its initial declaration to the chosen value.
4. **Unwrap the accepted content.** Delete the `<div data-impeccable-variant="N" style="display: contents">` that wraps it. Drop `data-impeccable-params` and any `data-p-*` attributes from it; those are live-mode plumbing, not source.
5. **Delete the inline `<style>` block, the `<!-- impeccable-param-values -->` comment if present, and both `<!-- impeccable-carbonize-start/end -->` markers.** Also drop any `@scope` rules for variants other than the accepted one; those are dead code now.

## Phase 2: Design Brief
After the interview and any required probes, synthesize everything into a structured design brief. Present it to the user for explicit confirmation before considering this command complete. Stop after asking for confirmation; do not proceed to craft or implementation in the same response unless the user has already approved the brief.
After the interview and any required probes, present a brief and **end your response**. The user must confirm before any implementation runs. Do not present a brief and then continue to code in the same response, even if the brief feels obvious to you. The user's confirmation is the gate.
**Choose the brief shape based on how clear the answers are:**
- **Compact form (3-5 bullets)** when discovery was crisp and the original prompt + PRODUCT.md already pinned scope, content, and direction. State what you're building, the visual lane, and end with one or two specific questions or a clear "confirm or override?" prompt. This is the default for typical craft requests with a clear prompt.
- **Full structured form (sections below)** when the task is genuinely ambiguous, multi-screen, or when the user asked for shape as a standalone step. Use this when the discipline of structure earns its weight.
Don't pad a clear brief into a long one to look thorough. A 70-line brief restating answers the user just gave is noise, not rigor. Equally, don't skip the confirmation pause to look efficient: the pause is the point.
If the user already said "approved" or "go" during discovery for the *exact direction you'd present*, that counts as confirmation; you may proceed without asking again. But if your brief adds anything the user hasn't seen and approved, you must stop and confirm.

## Skill bootstrap: skip the post-update-cleanup step
If you load the Impeccable skill from `.agents/skills/impeccable/SKILL.md` (or any sibling harness directory under this repo), it begins with a `<post-update-cleanup>` block that runs `scripts/cleanup-deprecated.mjs` and then self-deletes. **Do not run it here, and do not delete the block.** This repo is the source of truth for the skill; cleanup-deprecated assumes a consumer project and would touch legitimate source files. The block is regenerated from `source/skills/impeccable/SKILL.md` on every `bun run build`, so any deletion churns back. Skip it silently and proceed with the task.

Conventions: wrap the identifying heading text in straight double quotes inside snippets so the fixture test can extract it. jsdom-specific helpers `resolveBackground()`, `resolveGradientStops()`, and `parseGradientColors()` exist because `background:` shorthand isn't decomposed and computed colors aren't normalized in jsdom — use them. Reference rules to copy from: `side-tab` (border), `low-contrast` (color+gradient), `icon-tile-stack` (sibling relationship), `flat-type-hierarchy` (page-level).
## Commit & Pull Request Guidelines
Recent history favors short, imperative subjects such as `Fix: ...`, `Add ...`, `Improve ...`, or `Bump ...`. Keep commits focused and explain the user-facing impact when it is not obvious. PRs should summarize what changed, list validation performed, and call out regenerated artifacts like `dist/` or `build/`. Include screenshots for visible `public/` changes and mention affected providers when transform behavior changes.

## Releases
Tags are per-component because the three components ship independently: `skill-v` (`.claude-plugin/plugin.json` + `.claude-plugin/marketplace.json`), `cli-v` (`package.json`), `ext-v` (`extension/manifest.json`). Flow: bump the relevant manifest, add a changelog entry to `public/index.html` (skill = bare `vX.Y.Z`; CLI = `CLI vX.Y.Z`; extension = `Extension vX.Y.Z` — the prefix is how `scripts/release.mjs` finds the right block), commit, push, then `bun run release:<skill|cli|ext>` (or `--dry-run` first). The script refuses on a dirty tree, an unpushed HEAD, a missing changelog entry, or stale build outputs; skill and extension reruns of `bun run build` / `bun run build:extension` must produce zero diff. Skill releases attach `dist/universal.zip`; extension releases attach `dist/extension.zip`. CLI ships to npm via a separate `npm publish`, and the extension zip uploads to the Chrome Web Store manually — both reminded at the end of the script. Fix already-shipped notes with `gh release edit <tag> --notes-file <md>`.
