Paul BakausandClaude Opus 4.7 23b6b9cc0e chore(cli): bump to v2.1.9 + changelog
Patch bump. Detector adds the body-text-viewport-edge rule (29 total)
and fixes a class of false positives in modern token-based codebases
(OKLCH and var() resolution, anchor inheritance). Live screenshot
overlay no longer flashes solid black during loading.

The "live mode survives disconnects" CLI work and the italic-serif /
hero-eyebrow-chip rules from PR #129 already shipped in the v3.0.7
skill release notes, so they're not re-announced here.

Paul BakausandClaude Opus 4.7 735a0f4e4f chore(skill): bump to v3.1.0 + changelog
Minor bump because the changes since v3.0.7 are genuinely additive:

- Native subagent cross-compile pipeline and the Codex
  impeccable_asset_producer agent (Codex-only by design).
- Critique persistence: per-target snapshots, ignore.md, polish
  reads matching snapshot as additional signal.
- Codex-specific image flow extracted to reference/codex.md with
  the palette-first gate; craft.md is leaner for non-Codex.
- Detector: body-text-viewport-edge rule (29 total),
  OKLCH/var-resolution and anchor-inherit FP fixes.
- Brand register: inverse test and cultural-symbol palette
  guardrail.
- Shape gates restored where weakening had crossed the line
  (image-gen announcement, explicit brief confirmation).

Hero version link and full-history block updated. Manifests and
harness SKILL.md frontmatter all on 3.1.0.

Paul BakausandClaude Opus 4.7 8cef296996 craft + codex: extract Codex-specific image flow into codex.md
Codex is the only harness today with native image generation
(image_gen) and the shipped impeccable_asset_producer subagent. The
detailed mock/palette/asset workflow only applies there. Inlining
it in craft.md made every non-Codex harness read past 49 lines of
instructions it can't act on, and weakened the Codex-specific
guidance by averaging it down to a cross-provider lowest common
denominator.

Split:

- New skill/reference/codex.md: Steps A-F covering direction
  exploration, palette-first generation, mock generation against
  confirmed palette, approval loop, mock-fidelity inventory, and
  asset slicing via the impeccable_asset_producer subagent. Adds
  the "palette first" forcing function that wasn't in craft.md
  before; locking the palette before any mocks is what stops
  generated comps from drifting.

- craft.md Step 3 is now a one-line conditional: if the harness has
  native image generation, load codex.md and follow Steps A-F. If
  not, state in one line that the step is being skipped because the
  harness lacks native image generation, then proceed using the
  brief as the visual reference. Same announcement-required pattern
  as shape.md.

- craft.md Step 4 (asset extraction) is absorbed into codex.md
  Step F. Steps renumber: 5 (build), 6 (iterate), 7 (present)
  become 4, 5, 6.

Net: craft.md goes from 155 lines to 106 lines for non-Codex
providers. Codex gets a sharper 92-line image flow with the
palette-first gate that wasn't there before.

Paul BakausandClaude Opus 4.7 afc974d630 shape: restore image-gen announcement + explicit brief confirmation
Two specific gates that ea2e372 weakened, restored. The cadence
relaxation (one round is the default) and the compact-brief option
stay; this commit only undoes the changes that traded forcing
functions for model-judgment calls the model is bad at making.

1. Image-gen skip is announced, not silent. "Skip silently and
   proceed" gave models like GPT 5.5 license to elide image
   generation entirely. Restored to "state in one line that the
   image step is skipped because the harness lacks native image
   generation, then proceed." The one-line announcement is the
   conscious-decision forcing function.

2. Brief confirmation is explicit, not assumed. "If the user
   already said 'approved' or 'go' during discovery for the exact
   direction you'd present, that counts as confirmation" gave the
   model an out to skip the pause based on its own read. Restored
   to "stop and wait for explicit confirmation. You are not the
   judge of whether the user already approved."

Net: shape still asks one round by default and supports compact
briefs, but the two specific places where the model could skip
discipline without saying so are gone.

93a13f9882 Critique persistence: per-run snapshots, ignore list, polish reads as signal (#153)
* critique-storage: new helper for per-run snapshot persistence

Adds skill/scripts/critique-storage.mjs with:
- slugFromTarget(): mechanically derive a stable slug from a resolved
  file path or URL (NOT from the user's natural-language phrasing),
  so the same target lands in the same stream across runs even when
  dev-server ports drift or the user phrases it differently.
- writeSnapshot(): writes .impeccable/critique/<timestamp>__<slug>.md
  with a small YAML frontmatter (timestamp, slug, target, total_score,
  p0_count, p1_count) plus the report body.
- readLatestSnapshot(): newest snapshot for a slug, used by polish.
- readTrend(): last N frontmatter entries for a slug, used by critique
  to print the score trend line.
- readIgnoreList(): non-empty non-comment lines from ignore.md, the
  ONLY input critique consumes from prior runs.

No separate index.json. The snapshot files are the single source of
truth; trend reader globs them and parses frontmatter. Deleting a
snapshot removes it from the trend cleanly with no orphan rows.

CRITIQUE_DIR constant + getCritiqueDir / getCritiqueIgnorePath added
to impeccable-paths.mjs alongside the existing live-dir helpers.

19 unit tests in tests/critique-storage.test.mjs cover slug stability,
URL and file inputs, round-trip read/write, trend filtering by slug,
and ignore-list parsing.

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

* critique: persist snapshot per run, respect ignore.md

Two new steps wired into the critique flow:

- Setup: Resolve Target and Load Ignore List. Before gathering
  assessments, resolve the user's natural-language target ("the
  homepage") to a concrete artifact, compute the slug via
  critique-storage.mjs, and read ignore.md. Matching findings drop
  silently from the report. This is the only prior-run input
  critique consumes; anchoring on prior findings would defeat
  independent assessment.

- Persist the Snapshot. After the report is finalized (before Ask
  the User), write it to .impeccable/critique/<ts>__<slug>.md with
  structured frontmatter, then surface a one-line trend ("Trend for
  index-astro: 24 → 28 → 32") and the written path. First run says
  "no trend yet". Persistence is fire-and-forget; failures print and
  move on rather than blocking the rest of the flow.

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

* polish: read latest matching critique as fix backlog

When polish is invoked after critique on the same target, the
critique's P0/P1 findings are the right backlog; don't re-derive
them.

Adds a Setup step that resolves the target, computes the slug via
critique-storage.mjs slug, and reads the latest matching snapshot
via critique-storage.mjs latest. Found → use those P0/P1 items as
the polish backlog and mention the snapshot path. Not found →
proceed independently from a clean slate.

Explicitly does NOT read snapshots for other targets (cross-target
context is pollution). Explicitly does NOT cascade to atomic moves
(bolder, quieter, clarify, animate, etc.); those act on a specific
selection where the page-level critique would be noise.

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

* gitignore: .impeccable/critique/, opt ignore.md back in

Per-run critique snapshots are local artifacts (same precedent as
.impeccable/live/sessions/), but ignore.md carries user-curated
deferrals that may be worth sharing across a team. Negate-pattern
keeps it trackable while the snapshot files stay local.

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

* polish: reframe prior critique as additional signal, not backlog

Three corrections to the previous polish.md addition:

- "Polish is usually invoked after critique" is wrong; people polish
  without ever running critique. Dropped the presumption.
- "This is the only command that auto-reads prior critique" leaks
  cross-command scope into polish's reference file. Dropped.
- Treating critique findings as THE polish backlog biased polish to
  only fix what critique flagged, skipping its own checklist. The
  critique is one input among many; fold its P0/P1 items into the
  polish list, then do the normal pass.

Now lives as a short item 4 in Pre-Polish Assessment ("Pull in any
prior critique — optional signal") instead of a top-level Setup
section. Less prominent, doesn't presume invocation order.

* critique-storage: drop the ignore subcommand, read ignore.md directly

The ignore-list helper did nothing the model can't do inline: read a
markdown file, skip blank and #-prefix lines. It added a tool
roundtrip for no real value. Other helpers earn their keep by doing
work the model can't trivially do (path normalization, filename
generation, glob + frontmatter parsing); ignore-list did not.

Removed:
- `ignore` CLI subcommand
- readIgnoreList() module export + its tests
- getCritiqueIgnorePath() from impeccable-paths.mjs (now dead code)

Critique.md step 3 now just says "read .impeccable/critique/ignore.md
if it exists" and explains the format inline. Simpler.

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

* critique-storage: caller meta cannot override timestamp or slug

Spotted by Cursor Bugbot on the PR. writeSnapshot built frontmatter as
{ timestamp, slug, ...meta } so a caller-supplied meta blob (parsed
from the IMPECCABLE_CRITIQUE_META env var) could silently clobber the
computed timestamp and slug. The filename keeps the computed values,
so the frontmatter would drift from the filename and readTrend would
attribute scores to wrong timestamps with no visible error.

Swap to { ...meta, timestamp, slug } so internal values always win.
Add a regression test that passes corrupt meta and asserts the
frontmatter still matches the filename.

e7e923c4ef Skill + craft cleanup, detector hardening, native subagent pipeline (#152)
* 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.

* 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.

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

* 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).

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

* 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.

* 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).

* 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.

* 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.

* 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.

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

* 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.

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

* 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.

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

* 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.

# Codex: Visual Direction & Asset Production
This file is loaded by `$impeccable craft` when the harness has native image generation (currently Codex via `image_gen`). Other harnesses skip it. It covers the two craft steps that depend on real image generation: landing the visual direction, and producing the raster assets the implementation will compose.
Read this *before* generating any images. The order matters, and the per-step user pauses are what keep generated imagery from drifting away from the brief.
## Step A: Explore Directions with the User
Before generating anything, run a brief direction conversation grounded in the shape brief.
Ask **2-3 targeted questions** about visual lane, color strategy, atmosphere, and named anchor references. Don't enumerate generic menus; tie each question to the shape brief's answers. Example shape-grounded questions:
- "Brief says 'editorial restraint, Klim-adjacent.' Are we closer to a quiet specimen page or a magazine-spread feel with hero imagery?"
- "Palette strategy from shape was 'Committed.' Want it warm-grounded (deep oxblood + cream) or cool-grounded (slate + paper white)?"
Stop and wait for answers. These pin the palette before any pixel gets generated.
## Step B: Generate the Brand Palette First
Generate **one** palette artifact before any mocks. This is a small, focused image: typography pairing on the chosen background, primary + accent color swatches, one signature ornament or motif. Single image, single pass.
Why palette first: mocks generated against a vague color sense produce noise that drowns out the structural decisions. A confirmed palette is the first concrete contract for everything downstream.
Show the palette to the user. Ask one question: "This is the palette I'm locking in for the mocks. Confirm, or call out what to shift?"
Wait for confirmation. Do not generate mocks against an unconfirmed palette.
## Step C: Generate 1-3 Visual Mocks Against the Palette
Once the palette is confirmed, generate **1 to 3** high-fidelity north-star comps. Each mock must use the confirmed palette and typography. Mocks differ in *structural* direction (hierarchy, topology, density, composition), not in color or motif.
- Brand work: push visual identity, composition, mood, and signature motifs.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
Use the `image_gen` tool directly (or via the imagegen skill when available). Don't ask the user to install anything.
## Step D: Approval Loop
Show the comps. Ask what carries forward. Iterate until **one direction is approved** or the user explicitly delegates.
If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before moving to assets, summarize what to carry into code and what *not* to literalize from the mock. This is the handoff between visual exploration and semantic implementation.
## Step E: Mock Fidelity Inventory
Inventory the approved mock's major visible ingredients. For each, decide implementation: semantic HTML/CSS/SVG, generated raster, sourced raster, icon library, canvas/WebGL, or accepted omission.
Common ingredients to inventory:
- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)
- 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
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.
If a photographic, architectural, product, or place-led mock becomes generic CSS scenery, decorative diagrams, bullets, or copy, stop and fix it. That's a broken implementation, not a harmless interpretation.
Don't substitute a different hero composition or visual driver post-approval without user sign-off.
## Step F: Asset Slicing via the Asset Producer
Raster ingredients identified in Step E need clean production assets. Use the bundled `impeccable_asset_producer` subagent rather than producing inline.
Spawn it as a scoped subagent. If you do not have explicit permission to use agents, stop and ask:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
Pass to the agent:
- Approved mock path or screenshot reference
- Crop paths or a contact sheet with crop ids
- Output directory
- Required dimensions, format, transparency needs
- Avoid list
- Notes on what should remain semantic HTML/CSS/SVG instead of raster
Attach image generation capability to the spawned agent when the harness supports it. Do **not** load image-generation reference material into the parent thread.
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.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; reach for real, generated, or stock imagery when the mock or subject matter calls for actual visual content.

## Step 3: Land the Visual Direction (Capability-Gated)
## Step 3: Visual Direction & Assets (Harness-Gated)
Generate high-fidelity visual comps before implementation when all three are true:
If the harness has **native image generation** (currently Codex via `image_gen`), this step is mandatory. **Stop and load [codex.md](codex.md)**. It covers palette generation, mock exploration, the approval loop, mock-fidelity inventory, and asset slicing via the `impeccable_asset_producer` subagent. Follow Steps A-F in that file, then return here for Step 4.
- 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.
If the harness lacks native image generation, **state in one line that the visual-direction-by-generation step is being skipped because the harness lacks native image generation, then proceed**. The one-line announcement is required; it forces a conscious decision instead of letting the step quietly evaporate. The brief is your only visual reference. Implement directly from it, treating any named anchor references and the brief's "Design Direction" as the contract.
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.
Whether you generated mocks or not: don't replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy. Image-led briefs (restaurants, hotels, magazines, photography, hobbyist communities, food, travel, fashion, product) need real or sourced imagery in the build, not CSS scenery.
### What to generate
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.
- Brand work: push visual identity, composition, and mood aggressively.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
### Approval loop
Show the comps and ask what carries forward. Iterate until one direction is approved or the user delegates. If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before Step 4, summarize what to carry into code and what **not** to literalize from the mock. This is the handoff between visual exploration and semantic implementation.

## Step 4: Asset Extraction (Need-Gated)
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.
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:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
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.
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.

> **Additional context needed**: what the interface is trying to accomplish.
### Setup: Resolve Target and Load Ignore List
Before gathering assessments, do two small bookkeeping steps. They cost almost nothing and they're what makes critique iterative across runs.
1. **Resolve the primary artifact.** The user's phrasing ("the homepage", "the pricing flow") is not stable enough to track across runs. Resolve it to a concrete file path or URL: the same one you'd already need to scan code or open in a browser. Examples:
- "the homepage" → `site/pages/index.astro` (or `http://localhost:3000/` if you're inspecting live)
- "the settings modal" → the primary component file (e.g., `src/components/Settings.tsx`)
- "this page" → the URL or the page's source file
Prefer the source file path over the dev-server URL when both exist; ports drift between runs (`bun dev` vs `bun preview`), file paths don't.
2. **Compute the slug.** Run:
```bash
node .agents/skills/impeccable/scripts/critique-storage.mjs slug "<resolved-path-or-url>"
```
Keep the printed slug. It identifies this target's stream across runs. If the command exits non-zero ("no stable slug for input"), skip persistence for this run and tell the user; the trend won't update but the critique still goes ahead.
3. **Read the ignore list** at `.impeccable/critique/ignore.md` if it exists. Plain markdown; each non-empty, non-comment line is something the user has marked as "do not re-raise" (deferred tradeoffs, designer-intended deviations, detector false-positives the user accepts). When a finding's text matches a line here (case-insensitive substring against rule name or snippet), **drop it silently**. Do not mention it in the report. This is the ONLY input critique consumes from prior runs; anchoring on prior findings would defeat the point of independent assessment.
### Gather Assessments
Launch two independent assessments. **Neither may see the other's output.** This isolation is what makes the combined score honest. Running both in one head silently anchors them to each other; do not shortcut it for cost, speed, or context-size reasons.

- Prioritize ruthlessly. If everything is important, nothing is.
- Don't soften criticism. Developers need honest feedback to ship great design.
### Persist the Snapshot
Once the report above is finalized, write it to `.impeccable/critique/` so the user can refer back, and so `$impeccable polish` can pick up the priority issues without a copy-paste.
Skip this step if the Setup slug was null (vague or root-level target).
1. **Write the body to a temp file** so you can pipe it to the helper. Use the full report (heuristic table, anti-patterns verdict, priority issues, persona red flags) but stop before the "Ask the User" / "Recommended Actions" sections that come later.
2. **Pass the structured metadata** through `IMPECCABLE_CRITIQUE_META` (JSON), then run the write command:
```bash
IMPECCABLE_CRITIQUE_META='{"target":"<user phrasing>","total_score":<n>,"p0_count":<n>,"p1_count":<n>}' \
node .agents/skills/impeccable/scripts/critique-storage.mjs write <slug> <body-file>
```
The helper prints the absolute path it wrote.
3. **Read the trend** for context:
```bash
node .agents/skills/impeccable/scripts/critique-storage.mjs trend <slug> 5
```
This returns a JSON array of the last 5 frontmatter entries (including the one you just wrote).
4. **Append a single line to the user-visible output**, after the report and before the questions:
> **Trend for `<slug>` (last 5 runs): 24 → 28 → 32 → 29 → 32**
> Wrote `.impeccable/critique/<filename>`.
If this is the first run for the slug, the trend is just one score; say so: "First run for this target, no trend yet."
This is fire-and-forget. Do not show the user the helper's JSON output; only the human-readable trend line and the written path. Failures here should not block the rest of the flow; print the error and move on.
### Ask the User
**After presenting findings**, use targeted questions based on what was actually found. STOP and use Codex's structured user-input/question tool when available; if unavailable, ask directly in chat to clarify what you cannot infer. These answers will shape the action plan.

4. **Triage cosmetic vs functional**: Classify each issue as **cosmetic** (looks off, doesn't impede the user) or **functional** (breaks, blocks, or confuses the experience). When polish time is tight, functional issues ship first; cosmetic ones can land in a follow-up. Quality should be consistent; never perfect one corner while leaving another rough.
4. **Pull in any prior critique** (optional signal): If `$impeccable critique` has been run on the same target, its priority issues are a useful prior for what to address first. Resolve the target to a file path or URL, then:
```bash
slug=$(node .agents/skills/impeccable/scripts/critique-storage.mjs slug "<resolved>")
node .agents/skills/impeccable/scripts/critique-storage.mjs latest "$slug"
```
Exit 0 with body = found; fold the P0/P1 items into your polish list and mention the snapshot path so the user sees what you read. Exit 2 = no snapshot, continue without it. The critique is one input among many. Do your own pass either way.
5. **Triage cosmetic vs functional**: Classify each issue as **cosmetic** (looks off, doesn't impede the user) or **functional** (breaks, blocks, or confuses the experience).

# Codex: Visual Direction & Asset Production
This file is loaded by `/impeccable craft` when the harness has native image generation (currently Codex via `image_gen`). Other harnesses skip it. It covers the two craft steps that depend on real image generation: landing the visual direction, and producing the raster assets the implementation will compose.
Read this *before* generating any images. The order matters, and the per-step user pauses are what keep generated imagery from drifting away from the brief.
## Step A: Explore Directions with the User
Before generating anything, run a brief direction conversation grounded in the shape brief.
Ask **2-3 targeted questions** about visual lane, color strategy, atmosphere, and named anchor references. Don't enumerate generic menus; tie each question to the shape brief's answers. Example shape-grounded questions:
- "Brief says 'editorial restraint, Klim-adjacent.' Are we closer to a quiet specimen page or a magazine-spread feel with hero imagery?"
- "Palette strategy from shape was 'Committed.' Want it warm-grounded (deep oxblood + cream) or cool-grounded (slate + paper white)?"
Stop and wait for answers. These pin the palette before any pixel gets generated.
## Step B: Generate the Brand Palette First
Generate **one** palette artifact before any mocks. This is a small, focused image: typography pairing on the chosen background, primary + accent color swatches, one signature ornament or motif. Single image, single pass.
Why palette first: mocks generated against a vague color sense produce noise that drowns out the structural decisions. A confirmed palette is the first concrete contract for everything downstream.
Show the palette to the user. Ask one question: "This is the palette I'm locking in for the mocks. Confirm, or call out what to shift?"
Wait for confirmation. Do not generate mocks against an unconfirmed palette.
## Step C: Generate 1-3 Visual Mocks Against the Palette
Once the palette is confirmed, generate **1 to 3** high-fidelity north-star comps. Each mock must use the confirmed palette and typography. Mocks differ in *structural* direction (hierarchy, topology, density, composition), not in color or motif.
- Brand work: push visual identity, composition, mood, and signature motifs.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
Use the `image_gen` tool directly (or via the imagegen skill when available). Don't ask the user to install anything.
## Step D: Approval Loop
Show the comps. Ask what carries forward. Iterate until **one direction is approved** or the user explicitly delegates.
If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before moving to assets, summarize what to carry into code and what *not* to literalize from the mock. This is the handoff between visual exploration and semantic implementation.
## Step E: Mock Fidelity Inventory
Inventory the approved mock's major visible ingredients. For each, decide implementation: semantic HTML/CSS/SVG, generated raster, sourced raster, icon library, canvas/WebGL, or accepted omission.
Common ingredients to inventory:
- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)
- 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
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.
If a photographic, architectural, product, or place-led mock becomes generic CSS scenery, decorative diagrams, bullets, or copy, stop and fix it. That's a broken implementation, not a harmless interpretation.
Don't substitute a different hero composition or visual driver post-approval without user sign-off.
## Step F: Asset Slicing via the Asset Producer
Raster ingredients identified in Step E need clean production assets. Use the bundled `impeccable_asset_producer` subagent rather than producing inline.
Spawn it as a scoped subagent. If you do not have explicit permission to use agents, stop and ask:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
Pass to the agent:
- Approved mock path or screenshot reference
- Crop paths or a contact sheet with crop ids
- Output directory
- Required dimensions, format, transparency needs
- Avoid list
- Notes on what should remain semantic HTML/CSS/SVG instead of raster
Attach image generation capability to the spawned agent when the harness supports it. Do **not** load image-generation reference material into the parent thread.
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.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; reach for real, generated, or stock imagery when the mock or subject matter calls for actual visual content.

## Step 3: Land the Visual Direction (Capability-Gated)
## Step 3: Visual Direction & Assets (Harness-Gated)
Generate high-fidelity visual comps before implementation when all three are true:
If the harness has **native image generation** (currently Codex via `image_gen`), this step is mandatory. **Stop and load [codex.md](codex.md)**. It covers palette generation, mock exploration, the approval loop, mock-fidelity inventory, and asset slicing via the `impeccable_asset_producer` subagent. Follow Steps A-F in that file, then return here for Step 4.
- 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.
If the harness lacks native image generation, **state in one line that the visual-direction-by-generation step is being skipped because the harness lacks native image generation, then proceed**. The one-line announcement is required; it forces a conscious decision instead of letting the step quietly evaporate. The brief is your only visual reference. Implement directly from it, treating any named anchor references and the brief's "Design Direction" as the contract.
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.
Whether you generated mocks or not: don't replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy. Image-led briefs (restaurants, hotels, magazines, photography, hobbyist communities, food, travel, fashion, product) need real or sourced imagery in the build, not CSS scenery.
### What to generate
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.
- Brand work: push visual identity, composition, and mood aggressively.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
### Approval loop
Show the comps and ask what carries forward. Iterate until one direction is approved or the user delegates. If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before Step 4, summarize what to carry into code and what **not** to literalize from the mock. This is the handoff between visual exploration and semantic implementation.
### Mock fidelity inventory
Inventory the approved mock's major visible ingredients:
- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)
- 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

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 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.
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:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
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.
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.

### Setup: Resolve Target and Load Ignore List
Before gathering assessments, do two small bookkeeping steps. They cost almost nothing and they're what makes critique iterative across runs.
1. **Resolve the primary artifact.** The user's phrasing ("the homepage", "the pricing flow") is not stable enough to track across runs. Resolve it to a concrete file path or URL: the same one you'd already need to scan code or open in a browser. Examples:
- "the homepage" → `site/pages/index.astro` (or `http://localhost:3000/` if you're inspecting live)
- "the settings modal" → the primary component file (e.g., `src/components/Settings.tsx`)
- "this page" → the URL or the page's source file
Prefer the source file path over the dev-server URL when both exist; ports drift between runs (`bun dev` vs `bun preview`), file paths don't.
2. **Compute the slug.** Run:
```bash
node .claude/skills/impeccable/scripts/critique-storage.mjs slug "<resolved-path-or-url>"
```
Keep the printed slug. It identifies this target's stream across runs. If the command exits non-zero ("no stable slug for input"), skip persistence for this run and tell the user; the trend won't update but the critique still goes ahead.
3. **Read the ignore list** at `.impeccable/critique/ignore.md` if it exists. Plain markdown; each non-empty, non-comment line is something the user has marked as "do not re-raise" (deferred tradeoffs, designer-intended deviations, detector false-positives the user accepts). When a finding's text matches a line here (case-insensitive substring against rule name or snippet), **drop it silently**. Do not mention it in the report. This is the ONLY input critique consumes from prior runs; anchoring on prior findings would defeat the point of independent assessment.
### Gather Assessments
Launch two independent assessments. **Neither may see the other's output.** This isolation is what makes the combined score honest. Running both in one head silently anchors them to each other; do not shortcut it for cost, speed, or context-size reasons.

- Prioritize ruthlessly. If everything is important, nothing is.
- Don't soften criticism. Developers need honest feedback to ship great design.
### Persist the Snapshot
Once the report above is finalized, write it to `.impeccable/critique/` so the user can refer back, and so `/impeccable polish` can pick up the priority issues without a copy-paste.
Skip this step if the Setup slug was null (vague or root-level target).
1. **Write the body to a temp file** so you can pipe it to the helper. Use the full report (heuristic table, anti-patterns verdict, priority issues, persona red flags) but stop before the "Ask the User" / "Recommended Actions" sections that come later.
2. **Pass the structured metadata** through `IMPECCABLE_CRITIQUE_META` (JSON), then run the write command:
```bash
IMPECCABLE_CRITIQUE_META='{"target":"<user phrasing>","total_score":<n>,"p0_count":<n>,"p1_count":<n>}' \
node .claude/skills/impeccable/scripts/critique-storage.mjs write <slug> <body-file>
```
The helper prints the absolute path it wrote.
3. **Read the trend** for context:
```bash
node .claude/skills/impeccable/scripts/critique-storage.mjs trend <slug> 5
```
This returns a JSON array of the last 5 frontmatter entries (including the one you just wrote).
4. **Append a single line to the user-visible output**, after the report and before the questions:
> **Trend for `<slug>` (last 5 runs): 24 → 28 → 32 → 29 → 32**
> Wrote `.impeccable/critique/<filename>`.
If this is the first run for the slug, the trend is just one score; say so: "First run for this target, no trend yet."
This is fire-and-forget. Do not show the user the helper's JSON output; only the human-readable trend line and the written path. Failures here should not block the rest of the flow; print the error and move on.

4. **Triage cosmetic vs functional**: Classify each issue as **cosmetic** (looks off, doesn't impede the user) or **functional** (breaks, blocks, or confuses the experience). When polish time is tight, functional issues ship first; cosmetic ones can land in a follow-up. Quality should be consistent; never perfect one corner while leaving another rough.
4. **Pull in any prior critique** (optional signal): If `/impeccable critique` has been run on the same target, its priority issues are a useful prior for what to address first. Resolve the target to a file path or URL, then:
```bash
slug=$(node .claude/skills/impeccable/scripts/critique-storage.mjs slug "<resolved>")
node .claude/skills/impeccable/scripts/critique-storage.mjs latest "$slug"
```
Exit 0 with body = found; fold the P0/P1 items into your polish list and mention the snapshot path so the user sees what you read. Exit 2 = no snapshot, continue without it. The critique is one input among many. Do your own pass either way.
5. **Triage cosmetic vs functional**: Classify each issue as **cosmetic** (looks off, doesn't impede the user) or **functional** (breaks, blocks, or confuses the experience).

# Codex: Visual Direction & Asset Production
This file is loaded by `/impeccable craft` when the harness has native image generation (currently Codex via `image_gen`). Other harnesses skip it. It covers the two craft steps that depend on real image generation: landing the visual direction, and producing the raster assets the implementation will compose.
Read this *before* generating any images. The order matters, and the per-step user pauses are what keep generated imagery from drifting away from the brief.
## Step A: Explore Directions with the User
Before generating anything, run a brief direction conversation grounded in the shape brief.
Ask **2-3 targeted questions** about visual lane, color strategy, atmosphere, and named anchor references. Don't enumerate generic menus; tie each question to the shape brief's answers. Example shape-grounded questions:
- "Brief says 'editorial restraint, Klim-adjacent.' Are we closer to a quiet specimen page or a magazine-spread feel with hero imagery?"
- "Palette strategy from shape was 'Committed.' Want it warm-grounded (deep oxblood + cream) or cool-grounded (slate + paper white)?"
Stop and wait for answers. These pin the palette before any pixel gets generated.
## Step B: Generate the Brand Palette First
Generate **one** palette artifact before any mocks. This is a small, focused image: typography pairing on the chosen background, primary + accent color swatches, one signature ornament or motif. Single image, single pass.
Why palette first: mocks generated against a vague color sense produce noise that drowns out the structural decisions. A confirmed palette is the first concrete contract for everything downstream.
Show the palette to the user. Ask one question: "This is the palette I'm locking in for the mocks. Confirm, or call out what to shift?"
Wait for confirmation. Do not generate mocks against an unconfirmed palette.
## Step C: Generate 1-3 Visual Mocks Against the Palette
Once the palette is confirmed, generate **1 to 3** high-fidelity north-star comps. Each mock must use the confirmed palette and typography. Mocks differ in *structural* direction (hierarchy, topology, density, composition), not in color or motif.
- Brand work: push visual identity, composition, mood, and signature motifs.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
Use the `image_gen` tool directly (or via the imagegen skill when available). Don't ask the user to install anything.
## Step D: Approval Loop
Show the comps. Ask what carries forward. Iterate until **one direction is approved** or the user explicitly delegates.
If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before moving to assets, summarize what to carry into code and what *not* to literalize from the mock. This is the handoff between visual exploration and semantic implementation.
## Step E: Mock Fidelity Inventory
Inventory the approved mock's major visible ingredients. For each, decide implementation: semantic HTML/CSS/SVG, generated raster, sourced raster, icon library, canvas/WebGL, or accepted omission.
Common ingredients to inventory:
- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)
- 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
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.
If a photographic, architectural, product, or place-led mock becomes generic CSS scenery, decorative diagrams, bullets, or copy, stop and fix it. That's a broken implementation, not a harmless interpretation.
Don't substitute a different hero composition or visual driver post-approval without user sign-off.
## Step F: Asset Slicing via the Asset Producer
Raster ingredients identified in Step E need clean production assets. Use the bundled `impeccable_asset_producer` subagent rather than producing inline.
Spawn it as a scoped subagent. If you do not have explicit permission to use agents, stop and ask:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
Pass to the agent:
- Approved mock path or screenshot reference
- Crop paths or a contact sheet with crop ids
- Output directory
- Required dimensions, format, transparency needs
- Avoid list
- Notes on what should remain semantic HTML/CSS/SVG instead of raster
Attach image generation capability to the spawned agent when the harness supports it. Do **not** load image-generation reference material into the parent thread.
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.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; reach for real, generated, or stock imagery when the mock or subject matter calls for actual visual content.

## Step 3: Land the Visual Direction (Capability-Gated)
## Step 3: Visual Direction & Assets (Harness-Gated)
Generate high-fidelity visual comps before implementation when all three are true:
If the harness has **native image generation** (currently Codex via `image_gen`), this step is mandatory. **Stop and load [codex.md](codex.md)**. It covers palette generation, mock exploration, the approval loop, mock-fidelity inventory, and asset slicing via the `impeccable_asset_producer` subagent. Follow Steps A-F in that file, then return here for Step 4.
- 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.
If the harness lacks native image generation, **state in one line that the visual-direction-by-generation step is being skipped because the harness lacks native image generation, then proceed**. The one-line announcement is required; it forces a conscious decision instead of letting the step quietly evaporate. The brief is your only visual reference. Implement directly from it, treating any named anchor references and the brief's "Design Direction" as the contract.
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.
Whether you generated mocks or not: don't replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy. Image-led briefs (restaurants, hotels, magazines, photography, hobbyist communities, food, travel, fashion, product) need real or sourced imagery in the build, not CSS scenery.
### What to generate
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.
- Brand work: push visual identity, composition, and mood aggressively.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
### Approval loop
Show the comps and ask what carries forward. Iterate until one direction is approved or the user delegates. If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before Step 4, summarize what to carry into code and what **not** to literalize from the mock. This is the handoff between visual exploration and semantic implementation.
### Mock fidelity inventory
Inventory the approved mock's major visible ingredients:
- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)
- 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

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 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.
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:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
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.
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.

> **Additional context needed**: what the interface is trying to accomplish.
### Setup: Resolve Target and Load Ignore List
Before gathering assessments, do two small bookkeeping steps. They cost almost nothing and they're what makes critique iterative across runs.
1. **Resolve the primary artifact.** The user's phrasing ("the homepage", "the pricing flow") is not stable enough to track across runs. Resolve it to a concrete file path or URL: the same one you'd already need to scan code or open in a browser. Examples:
- "the homepage" → `site/pages/index.astro` (or `http://localhost:3000/` if you're inspecting live)
- "the settings modal" → the primary component file (e.g., `src/components/Settings.tsx`)
- "this page" → the URL or the page's source file
Prefer the source file path over the dev-server URL when both exist; ports drift between runs (`bun dev` vs `bun preview`), file paths don't.
2. **Compute the slug.** Run:
```bash
node .cursor/skills/impeccable/scripts/critique-storage.mjs slug "<resolved-path-or-url>"
```
Keep the printed slug. It identifies this target's stream across runs. If the command exits non-zero ("no stable slug for input"), skip persistence for this run and tell the user; the trend won't update but the critique still goes ahead.
3. **Read the ignore list** at `.impeccable/critique/ignore.md` if it exists. Plain markdown; each non-empty, non-comment line is something the user has marked as "do not re-raise" (deferred tradeoffs, designer-intended deviations, detector false-positives the user accepts). When a finding's text matches a line here (case-insensitive substring against rule name or snippet), **drop it silently**. Do not mention it in the report. This is the ONLY input critique consumes from prior runs; anchoring on prior findings would defeat the point of independent assessment.
### Gather Assessments
Launch two independent assessments. **Neither may see the other's output.** This isolation is what makes the combined score honest. Running both in one head silently anchors them to each other; do not shortcut it for cost, speed, or context-size reasons.
@@ -164,6 +182,36 @@ Provocative questions that might unlock better solutions:
- Prioritize ruthlessly. If everything is important, nothing is.
- Don't soften criticism. Developers need honest feedback to ship great design.
### Persist the Snapshot
Once the report above is finalized, write it to `.impeccable/critique/` so the user can refer back, and so `/impeccable polish` can pick up the priority issues without a copy-paste.
Skip this step if the Setup slug was null (vague or root-level target).
1. **Write the body to a temp file** so you can pipe it to the helper. Use the full report (heuristic table, anti-patterns verdict, priority issues, persona red flags) but stop before the "Ask the User" / "Recommended Actions" sections that come later.
2. **Pass the structured metadata** through `IMPECCABLE_CRITIQUE_META` (JSON), then run the write command:
```bash
IMPECCABLE_CRITIQUE_META='{"target":"<user phrasing>","total_score":<n>,"p0_count":<n>,"p1_count":<n>}' \
node .cursor/skills/impeccable/scripts/critique-storage.mjs write <slug> <body-file>
```
The helper prints the absolute path it wrote.
3. **Read the trend** for context:
```bash
node .cursor/skills/impeccable/scripts/critique-storage.mjs trend <slug> 5
```
This returns a JSON array of the last 5 frontmatter entries (including the one you just wrote).
4. **Append a single line to the user-visible output**, after the report and before the questions:
> **Trend for `<slug>` (last 5 runs): 24 → 28 → 32 → 29 → 32**
> Wrote `.impeccable/critique/<filename>`.
If this is the first run for the slug, the trend is just one score; say so: "First run for this target, no trend yet."
This is fire-and-forget. Do not show the user the helper's JSON output; only the human-readable trend line and the written path. Failures here should not block the rest of the flow; print the error and move on.
### Ask the User

4. **Triage cosmetic vs functional**: Classify each issue as **cosmetic** (looks off, doesn't impede the user) or **functional** (breaks, blocks, or confuses the experience). When polish time is tight, functional issues ship first; cosmetic ones can land in a follow-up. Quality should be consistent; never perfect one corner while leaving another rough.
4. **Pull in any prior critique** (optional signal): If `/impeccable critique` has been run on the same target, its priority issues are a useful prior for what to address first. Resolve the target to a file path or URL, then:
```bash
slug=$(node .cursor/skills/impeccable/scripts/critique-storage.mjs slug "<resolved>")
node .cursor/skills/impeccable/scripts/critique-storage.mjs latest "$slug"
```
Exit 0 with body = found; fold the P0/P1 items into your polish list and mention the snapshot path so the user sees what you read. Exit 2 = no snapshot, continue without it. The critique is one input among many. Do your own pass either way.
5. **Triage cosmetic vs functional**: Classify each issue as **cosmetic** (looks off, doesn't impede the user) or **functional** (breaks, blocks, or confuses the experience). When polish time is tight, functional issues ship first; cosmetic ones can land in a follow-up. Quality should be consistent; never perfect one corner while leaving another rough.

# Codex: Visual Direction & Asset Production
This file is loaded by `/impeccable craft` when the harness has native image generation (currently Codex via `image_gen`). Other harnesses skip it. It covers the two craft steps that depend on real image generation: landing the visual direction, and producing the raster assets the implementation will compose.
Read this *before* generating any images. The order matters, and the per-step user pauses are what keep generated imagery from drifting away from the brief.
## Step A: Explore Directions with the User
Before generating anything, run a brief direction conversation grounded in the shape brief.
Ask **2-3 targeted questions** about visual lane, color strategy, atmosphere, and named anchor references. Don't enumerate generic menus; tie each question to the shape brief's answers. Example shape-grounded questions:
- "Brief says 'editorial restraint, Klim-adjacent.' Are we closer to a quiet specimen page or a magazine-spread feel with hero imagery?"
- "Palette strategy from shape was 'Committed.' Want it warm-grounded (deep oxblood + cream) or cool-grounded (slate + paper white)?"
Stop and wait for answers. These pin the palette before any pixel gets generated.
## Step B: Generate the Brand Palette First
Generate **one** palette artifact before any mocks. This is a small, focused image: typography pairing on the chosen background, primary + accent color swatches, one signature ornament or motif. Single image, single pass.
Why palette first: mocks generated against a vague color sense produce noise that drowns out the structural decisions. A confirmed palette is the first concrete contract for everything downstream.
Show the palette to the user. Ask one question: "This is the palette I'm locking in for the mocks. Confirm, or call out what to shift?"
Wait for confirmation. Do not generate mocks against an unconfirmed palette.
## Step C: Generate 1-3 Visual Mocks Against the Palette
Once the palette is confirmed, generate **1 to 3** high-fidelity north-star comps. Each mock must use the confirmed palette and typography. Mocks differ in *structural* direction (hierarchy, topology, density, composition), not in color or motif.
- Brand work: push visual identity, composition, mood, and signature motifs.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
Use the `image_gen` tool directly (or via the imagegen skill when available). Don't ask the user to install anything.
## Step D: Approval Loop
Show the comps. Ask what carries forward. Iterate until **one direction is approved** or the user explicitly delegates.
If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before moving to assets, summarize what to carry into code and what *not* to literalize from the mock. This is the handoff between visual exploration and semantic implementation.
## Step E: Mock Fidelity Inventory
Inventory the approved mock's major visible ingredients. For each, decide implementation: semantic HTML/CSS/SVG, generated raster, sourced raster, icon library, canvas/WebGL, or accepted omission.
Common ingredients to inventory:
- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)
- 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
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.
If a photographic, architectural, product, or place-led mock becomes generic CSS scenery, decorative diagrams, bullets, or copy, stop and fix it. That's a broken implementation, not a harmless interpretation.
Don't substitute a different hero composition or visual driver post-approval without user sign-off.
## Step F: Asset Slicing via the Asset Producer
Raster ingredients identified in Step E need clean production assets. Use the bundled `impeccable_asset_producer` subagent rather than producing inline.
Spawn it as a scoped subagent. If you do not have explicit permission to use agents, stop and ask:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
Pass to the agent:
- Approved mock path or screenshot reference
- Crop paths or a contact sheet with crop ids
- Output directory
- Required dimensions, format, transparency needs
- Avoid list
- Notes on what should remain semantic HTML/CSS/SVG instead of raster
Attach image generation capability to the spawned agent when the harness supports it. Do **not** load image-generation reference material into the parent thread.
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.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; reach for real, generated, or stock imagery when the mock or subject matter calls for actual visual content.

## Step 3: Land the Visual Direction (Capability-Gated)
## Step 3: Visual Direction & Assets (Harness-Gated)
Generate high-fidelity visual comps before implementation when all three are true:
If the harness has **native image generation** (currently Codex via `image_gen`), this step is mandatory. **Stop and load [codex.md](codex.md)**. It covers palette generation, mock exploration, the approval loop, mock-fidelity inventory, and asset slicing via the `impeccable_asset_producer` subagent. Follow Steps A-F in that file, then return here for Step 4.
- 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.
If the harness lacks native image generation, **state in one line that the visual-direction-by-generation step is being skipped because the harness lacks native image generation, then proceed**. The one-line announcement is required; it forces a conscious decision instead of letting the step quietly evaporate. The brief is your only visual reference. Implement directly from it, treating any named anchor references and the brief's "Design Direction" as the contract.
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.
Whether you generated mocks or not: don't replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy. Image-led briefs (restaurants, hotels, magazines, photography, hobbyist communities, food, travel, fashion, product) need real or sourced imagery in the build, not CSS scenery.
### What to generate
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.
- Brand work: push visual identity, composition, and mood aggressively.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
### Approval loop
Show the comps and ask what carries forward. Iterate until one direction is approved or the user delegates. If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before Step 4, summarize what to carry into code and what **not** to literalize from the mock. This is the handoff between visual exploration and semantic implementation.

- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)
- Nav and primary CTA treatment
- Section sequence, especially the second fold
- Image-native content the concept depends on

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 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.
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:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
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.
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.

> **Additional context needed**: what the interface is trying to accomplish.
### Setup: Resolve Target and Load Ignore List
Before gathering assessments, do two small bookkeeping steps. They cost almost nothing and they're what makes critique iterative across runs.
1. **Resolve the primary artifact.** The user's phrasing ("the homepage", "the pricing flow") is not stable enough to track across runs. Resolve it to a concrete file path or URL: the same one you'd already need to scan code or open in a browser. Examples:
- "the homepage" → `site/pages/index.astro` (or `http://localhost:3000/` if you're inspecting live)
- "the settings modal" → the primary component file (e.g., `src/components/Settings.tsx`)
- "this page" → the URL or the page's source file
Prefer the source file path over the dev-server URL when both exist; ports drift between runs (`bun dev` vs `bun preview`), file paths don't.
2. **Compute the slug.** Run:
```bash
node .gemini/skills/impeccable/scripts/critique-storage.mjs slug "<resolved-path-or-url>"
```
Keep the printed slug. It identifies this target's stream across runs. If the command exits non-zero ("no stable slug for input"), skip persistence for this run and tell the user; the trend won't update but the critique still goes ahead.
3. **Read the ignore list** at `.impeccable/critique/ignore.md` if it exists. Plain markdown; each non-empty, non-comment line is something the user has marked as "do not re-raise" (deferred tradeoffs, designer-intended deviations, detector false-positives the user accepts). When a finding's text matches a line here (case-insensitive substring against rule name or snippet), **drop it silently**. Do not mention it in the report. This is the ONLY input critique consumes from prior runs; anchoring on prior findings would defeat the point of independent assessment.
### Gather Assessments
Launch two independent assessments. **Neither may see the other's output.** This isolation is what makes the combined score honest. Running both in one head silently anchors them to each other; do not shortcut it for cost, speed, or context-size reasons.
@@ -164,6 +182,36 @@ Provocative questions that might unlock better solutions:
- Prioritize ruthlessly. If everything is important, nothing is.
- Don't soften criticism. Developers need honest feedback to ship great design.
### Persist the Snapshot
Once the report above is finalized, write it to `.impeccable/critique/` so the user can refer back, and so `/impeccable polish` can pick up the priority issues without a copy-paste.
Skip this step if the Setup slug was null (vague or root-level target).
1. **Write the body to a temp file** so you can pipe it to the helper. Use the full report (heuristic table, anti-patterns verdict, priority issues, persona red flags) but stop before the "Ask the User" / "Recommended Actions" sections that come later.
2. **Pass the structured metadata** through `IMPECCABLE_CRITIQUE_META` (JSON), then run the write command:
```bash
IMPECCABLE_CRITIQUE_META='{"target":"<user phrasing>","total_score":<n>,"p0_count":<n>,"p1_count":<n>}' \
node .gemini/skills/impeccable/scripts/critique-storage.mjs write <slug> <body-file>
```
The helper prints the absolute path it wrote.
3. **Read the trend** for context:
```bash
node .gemini/skills/impeccable/scripts/critique-storage.mjs trend <slug> 5
```
This returns a JSON array of the last 5 frontmatter entries (including the one you just wrote).
4. **Append a single line to the user-visible output**, after the report and before the questions:
> **Trend for `<slug>` (last 5 runs): 24 → 28 → 32 → 29 → 32**
> Wrote `.impeccable/critique/<filename>`.
If this is the first run for the slug, the trend is just one score; say so: "First run for this target, no trend yet."
This is fire-and-forget. Do not show the user the helper's JSON output; only the human-readable trend line and the written path. Failures here should not block the rest of the flow; print the error and move on.

4. **Triage cosmetic vs functional**: Classify each issue as **cosmetic** (looks off, doesn't impede the user) or **functional** (breaks, blocks, or confuses the experience). When polish time is tight, functional issues ship first; cosmetic ones can land in a follow-up. Quality should be consistent; never perfect one corner while leaving another rough.
4. **Pull in any prior critique** (optional signal): If `/impeccable critique` has been run on the same target, its priority issues are a useful prior for what to address first. Resolve the target to a file path or URL, then:
```bash
slug=$(node .gemini/skills/impeccable/scripts/critique-storage.mjs slug "<resolved>")
node .gemini/skills/impeccable/scripts/critique-storage.mjs latest "$slug"
```
Exit 0 with body = found; fold the P0/P1 items into your polish list and mention the snapshot path so the user sees what you read. Exit 2 = no snapshot, continue without it. The critique is one input among many. Do your own pass either way.
5. **Triage cosmetic vs functional**: Classify each issue as **cosmetic** (looks off, doesn't impede the user) or **functional** (breaks, blocks, or confuses the experience).

# Codex: Visual Direction & Asset Production
This file is loaded by `/impeccable craft` when the harness has native image generation (currently Codex via `image_gen`). Other harnesses skip it. It covers the two craft steps that depend on real image generation: landing the visual direction, and producing the raster assets the implementation will compose.
Read this *before* generating any images. The order matters, and the per-step user pauses are what keep generated imagery from drifting away from the brief.
## Step A: Explore Directions with the User
Before generating anything, run a brief direction conversation grounded in the shape brief.
Ask **2-3 targeted questions** about visual lane, color strategy, atmosphere, and named anchor references. Don't enumerate generic menus; tie each question to the shape brief's answers. Example shape-grounded questions:
- "Brief says 'editorial restraint, Klim-adjacent.' Are we closer to a quiet specimen page or a magazine-spread feel with hero imagery?"
- "Palette strategy from shape was 'Committed.' Want it warm-grounded (deep oxblood + cream) or cool-grounded (slate + paper white)?"
Stop and wait for answers. These pin the palette before any pixel gets generated.
## Step B: Generate the Brand Palette First
Generate **one** palette artifact before any mocks. This is a small, focused image: typography pairing on the chosen background, primary + accent color swatches, one signature ornament or motif. Single image, single pass.
Why palette first: mocks generated against a vague color sense produce noise that drowns out the structural decisions. A confirmed palette is the first concrete contract for everything downstream.
Show the palette to the user. Ask one question: "This is the palette I'm locking in for the mocks. Confirm, or call out what to shift?"
Wait for confirmation. Do not generate mocks against an unconfirmed palette.
## Step C: Generate 1-3 Visual Mocks Against the Palette
Once the palette is confirmed, generate **1 to 3** high-fidelity north-star comps. Each mock must use the confirmed palette and typography. Mocks differ in *structural* direction (hierarchy, topology, density, composition), not in color or motif.
- Brand work: push visual identity, composition, mood, and signature motifs.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
Use the `image_gen` tool directly (or via the imagegen skill when available). Don't ask the user to install anything.
## Step D: Approval Loop
Show the comps. Ask what carries forward. Iterate until **one direction is approved** or the user explicitly delegates.
If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before moving to assets, summarize what to carry into code and what *not* to literalize from the mock. This is the handoff between visual exploration and semantic implementation.
## Step E: Mock Fidelity Inventory
Inventory the approved mock's major visible ingredients. For each, decide implementation: semantic HTML/CSS/SVG, generated raster, sourced raster, icon library, canvas/WebGL, or accepted omission.
Common ingredients to inventory:
- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)
- 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
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.
If a photographic, architectural, product, or place-led mock becomes generic CSS scenery, decorative diagrams, bullets, or copy, stop and fix it. That's a broken implementation, not a harmless interpretation.
Don't substitute a different hero composition or visual driver post-approval without user sign-off.
## Step F: Asset Slicing via the Asset Producer
Raster ingredients identified in Step E need clean production assets. Use the bundled `impeccable_asset_producer` subagent rather than producing inline.
Spawn it as a scoped subagent. If you do not have explicit permission to use agents, stop and ask:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
Pass to the agent:
- Approved mock path or screenshot reference
- Crop paths or a contact sheet with crop ids
- Output directory
- Required dimensions, format, transparency needs
- Avoid list
- Notes on what should remain semantic HTML/CSS/SVG instead of raster
Attach image generation capability to the spawned agent when the harness supports it. Do **not** load image-generation reference material into the parent thread.
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.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; reach for real, generated, or stock imagery when the mock or subject matter calls for actual visual content.

## Step 3: Land the Visual Direction (Capability-Gated)
## Step 3: Visual Direction & Assets (Harness-Gated)
Generate high-fidelity visual comps before implementation when all three are true:
If the harness has **native image generation** (currently Codex via `image_gen`), this step is mandatory. **Stop and load [codex.md](codex.md)**. It covers palette generation, mock exploration, the approval loop, mock-fidelity inventory, and asset slicing via the `impeccable_asset_producer` subagent. Follow Steps A-F in that file, then return here for Step 4.
- 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.
If the harness lacks native image generation, **state in one line that the visual-direction-by-generation step is being skipped because the harness lacks native image generation, then proceed**. The one-line announcement is required; it forces a conscious decision instead of letting the step quietly evaporate. The brief is your only visual reference. Implement directly from it, treating any named anchor references and the brief's "Design Direction" as the contract.
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.
Whether you generated mocks or not: don't replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy. Image-led briefs (restaurants, hotels, magazines, photography, hobbyist communities, food, travel, fashion, product) need real or sourced imagery in the build, not CSS scenery.
### What to generate
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.
- Brand work: push visual identity, composition, and mood aggressively.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
### Approval loop
Show the comps and ask what carries forward. Iterate until one direction is approved or the user delegates. If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before Step 4, summarize what to carry into code and what **not** to literalize from the mock. This is the handoff between visual exploration and semantic implementation.

- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)
- Nav and primary CTA treatment
- Section sequence, especially the second fold
- Image-native content the concept depends on

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 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.
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:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
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.
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.

> **Additional context needed**: what the interface is trying to accomplish.
### Setup: Resolve Target and Load Ignore List
Before gathering assessments, do two small bookkeeping steps. They cost almost nothing and they're what makes critique iterative across runs.
1. **Resolve the primary artifact.** The user's phrasing ("the homepage", "the pricing flow") is not stable enough to track across runs. Resolve it to a concrete file path or URL: the same one you'd already need to scan code or open in a browser. Examples:
- "the homepage" → `site/pages/index.astro` (or `http://localhost:3000/` if you're inspecting live)
- "the settings modal" → the primary component file (e.g., `src/components/Settings.tsx`)
- "this page" → the URL or the page's source file
Prefer the source file path over the dev-server URL when both exist; ports drift between runs (`bun dev` vs `bun preview`), file paths don't.
2. **Compute the slug.** Run:
```bash
node .github/skills/impeccable/scripts/critique-storage.mjs slug "<resolved-path-or-url>"
```
Keep the printed slug. It identifies this target's stream across runs. If the command exits non-zero ("no stable slug for input"), skip persistence for this run and tell the user; the trend won't update but the critique still goes ahead.
3. **Read the ignore list** at `.impeccable/critique/ignore.md` if it exists. Plain markdown; each non-empty, non-comment line is something the user has marked as "do not re-raise" (deferred tradeoffs, designer-intended deviations, detector false-positives the user accepts). When a finding's text matches a line here (case-insensitive substring against rule name or snippet), **drop it silently**. Do not mention it in the report. This is the ONLY input critique consumes from prior runs; anchoring on prior findings would defeat the point of independent assessment.
### Gather Assessments
Launch two independent assessments. **Neither may see the other's output.** This isolation is what makes the combined score honest. Running both in one head silently anchors them to each other; do not shortcut it for cost, speed, or context-size reasons.

- Prioritize ruthlessly. If everything is important, nothing is.
- Don't soften criticism. Developers need honest feedback to ship great design.
### Persist the Snapshot
Once the report above is finalized, write it to `.impeccable/critique/` so the user can refer back, and so `/impeccable polish` can pick up the priority issues without a copy-paste.
Skip this step if the Setup slug was null (vague or root-level target).
1. **Write the body to a temp file** so you can pipe it to the helper. Use the full report (heuristic table, anti-patterns verdict, priority issues, persona red flags) but stop before the "Ask the User" / "Recommended Actions" sections that come later.
2. **Pass the structured metadata** through `IMPECCABLE_CRITIQUE_META` (JSON), then run the write command:
```bash
IMPECCABLE_CRITIQUE_META='{"target":"<user phrasing>","total_score":<n>,"p0_count":<n>,"p1_count":<n>}' \
node .github/skills/impeccable/scripts/critique-storage.mjs write <slug> <body-file>
```
The helper prints the absolute path it wrote.
3. **Read the trend** for context:
```bash
node .github/skills/impeccable/scripts/critique-storage.mjs trend <slug> 5
```
This returns a JSON array of the last 5 frontmatter entries (including the one you just wrote).
4. **Append a single line to the user-visible output**, after the report and before the questions:
> **Trend for `<slug>` (last 5 runs): 24 → 28 → 32 → 29 → 32**
> Wrote `.impeccable/critique/<filename>`.
If this is the first run for the slug, the trend is just one score; say so: "First run for this target, no trend yet."
This is fire-and-forget. Do not show the user the helper's JSON output; only the human-readable trend line and the written path. Failures here should not block the rest of the flow; print the error and move on.
### Ask the User

4. **Triage cosmetic vs functional**: Classify each issue as **cosmetic** (looks off, doesn't impede the user) or **functional** (breaks, blocks, or confuses the experience). When polish time is tight, functional issues ship first; cosmetic ones can land in a follow-up. Quality should be consistent; never perfect one corner while leaving another rough.
4. **Pull in any prior critique** (optional signal): If `/impeccable critique` has been run on the same target, its priority issues are a useful prior for what to address first. Resolve the target to a file path or URL, then:
```bash
slug=$(node .github/skills/impeccable/scripts/critique-storage.mjs slug "<resolved>")
node .github/skills/impeccable/scripts/critique-storage.mjs latest "$slug"
```
Exit 0 with body = found; fold the P0/P1 items into your polish list and mention the snapshot path so the user sees what you read. Exit 2 = no snapshot, continue without it. The critique is one input among many. Do your own pass either way.
5. **Triage cosmetic vs functional**: Classify each issue as **cosmetic** (looks off, doesn't impede the user) or **functional** (breaks, blocks, or confuses the experience). When polish time is tight, functional issues ship first; cosmetic ones can land in a follow-up. Quality should be consistent; never perfect one corner while leaving another rough.

# Codex: Visual Direction & Asset Production
This file is loaded by `/impeccable craft` when the harness has native image generation (currently Codex via `image_gen`). Other harnesses skip it. It covers the two craft steps that depend on real image generation: landing the visual direction, and producing the raster assets the implementation will compose.
Read this *before* generating any images. The order matters, and the per-step user pauses are what keep generated imagery from drifting away from the brief.
## Step A: Explore Directions with the User
Before generating anything, run a brief direction conversation grounded in the shape brief.
Ask **2-3 targeted questions** about visual lane, color strategy, atmosphere, and named anchor references. Don't enumerate generic menus; tie each question to the shape brief's answers. Example shape-grounded questions:
- "Brief says 'editorial restraint, Klim-adjacent.' Are we closer to a quiet specimen page or a magazine-spread feel with hero imagery?"
- "Palette strategy from shape was 'Committed.' Want it warm-grounded (deep oxblood + cream) or cool-grounded (slate + paper white)?"
Stop and wait for answers. These pin the palette before any pixel gets generated.
## Step B: Generate the Brand Palette First
Generate **one** palette artifact before any mocks. This is a small, focused image: typography pairing on the chosen background, primary + accent color swatches, one signature ornament or motif. Single image, single pass.
Why palette first: mocks generated against a vague color sense produce noise that drowns out the structural decisions. A confirmed palette is the first concrete contract for everything downstream.
Show the palette to the user. Ask one question: "This is the palette I'm locking in for the mocks. Confirm, or call out what to shift?"
Wait for confirmation. Do not generate mocks against an unconfirmed palette.
## Step C: Generate 1-3 Visual Mocks Against the Palette
Once the palette is confirmed, generate **1 to 3** high-fidelity north-star comps. Each mock must use the confirmed palette and typography. Mocks differ in *structural* direction (hierarchy, topology, density, composition), not in color or motif.
- Brand work: push visual identity, composition, mood, and signature motifs.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
Use the `image_gen` tool directly (or via the imagegen skill when available). Don't ask the user to install anything.
## Step D: Approval Loop
Show the comps. Ask what carries forward. Iterate until **one direction is approved** or the user explicitly delegates.
If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before moving to assets, summarize what to carry into code and what *not* to literalize from the mock. This is the handoff between visual exploration and semantic implementation.
## Step E: Mock Fidelity Inventory
Inventory the approved mock's major visible ingredients. For each, decide implementation: semantic HTML/CSS/SVG, generated raster, sourced raster, icon library, canvas/WebGL, or accepted omission.
Common ingredients to inventory:
- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)
- 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
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.
If a photographic, architectural, product, or place-led mock becomes generic CSS scenery, decorative diagrams, bullets, or copy, stop and fix it. That's a broken implementation, not a harmless interpretation.
Don't substitute a different hero composition or visual driver post-approval without user sign-off.
## Step F: Asset Slicing via the Asset Producer
Raster ingredients identified in Step E need clean production assets. Use the bundled `impeccable_asset_producer` subagent rather than producing inline.
Spawn it as a scoped subagent. If you do not have explicit permission to use agents, stop and ask:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
Pass to the agent:
- Approved mock path or screenshot reference
- Crop paths or a contact sheet with crop ids
- Output directory
- Required dimensions, format, transparency needs
- Avoid list
- Notes on what should remain semantic HTML/CSS/SVG instead of raster
Attach image generation capability to the spawned agent when the harness supports it. Do **not** load image-generation reference material into the parent thread.
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.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; reach for real, generated, or stock imagery when the mock or subject matter calls for actual visual content.

Once Steps A through F are complete, return to `craft.md` Step 5 (Build to Production Quality). The implementation builds against the confirmed palette, approved mock, and the assets the producer wrote.

## Step 3: Land the Visual Direction (Capability-Gated)
## Step 3: Visual Direction & Assets (Harness-Gated)
Generate high-fidelity visual comps before implementation when all three are true:
If the harness has **native image generation** (currently Codex via `image_gen`), this step is mandatory. **Stop and load [codex.md](codex.md)**. It covers palette generation, mock exploration, the approval loop, mock-fidelity inventory, and asset slicing via the `impeccable_asset_producer` subagent. Follow Steps A-F in that file, then return here for Step 4.
- 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.
If the harness lacks native image generation, **state in one line that the visual-direction-by-generation step is being skipped because the harness lacks native image generation, then proceed**. The one-line announcement is required; it forces a conscious decision instead of letting the step quietly evaporate. The brief is your only visual reference. Implement directly from it, treating any named anchor references and the brief's "Design Direction" as the contract.
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.
Whether you generated mocks or not: don't replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy. Image-led briefs (restaurants, hotels, magazines, photography, hobbyist communities, food, travel, fashion, product) need real or sourced imagery in the build, not CSS scenery.
### What to generate
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.
- Brand work: push visual identity, composition, and mood aggressively.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
### Approval loop
Show the comps and ask what carries forward. Iterate until one direction is approved or the user delegates. If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before Step 4, summarize what to carry into code and what **not** to literalize from the mock. This is the handoff between visual exploration and semantic implementation.

- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)

## Step 4: Asset Extraction (Need-Gated)
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.
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:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
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.
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.

> **Additional context needed**: what the interface is trying to accomplish.
### Setup: Resolve Target and Load Ignore List
Before gathering assessments, do two small bookkeeping steps. They cost almost nothing and they're what makes critique iterative across runs.
1. **Resolve the primary artifact.** The user's phrasing ("the homepage", "the pricing flow") is not stable enough to track across runs. Resolve it to a concrete file path or URL: the same one you'd already need to scan code or open in a browser. Examples:
- "the homepage" → `site/pages/index.astro` (or `http://localhost:3000/` if you're inspecting live)
- "the settings modal" → the primary component file (e.g., `src/components/Settings.tsx`)
- "this page" → the URL or the page's source file
Prefer the source file path over the dev-server URL when both exist; ports drift between runs (`bun dev` vs `bun preview`), file paths don't.
2. **Compute the slug.** Run:
```bash
node .kiro/skills/impeccable/scripts/critique-storage.mjs slug "<resolved-path-or-url>"
```
Keep the printed slug. It identifies this target's stream across runs. If the command exits non-zero ("no stable slug for input"), skip persistence for this run and tell the user; the trend won't update but the critique still goes ahead.
3. **Read the ignore list** at `.impeccable/critique/ignore.md` if it exists. Plain markdown; each non-empty, non-comment line is something the user has marked as "do not re-raise" (deferred tradeoffs, designer-intended deviations, detector false-positives the user accepts). When a finding's text matches a line here (case-insensitive substring against rule name or snippet), **drop it silently**. Do not mention it in the report. This is the ONLY input critique consumes from prior runs; anchoring on prior findings would defeat the point of independent assessment.
### Gather Assessments
Launch two independent assessments. **Neither may see the other's output.** This isolation is what makes the combined score honest. Running both in one head silently anchors them to each other; do not shortcut it for cost, speed, or context-size reasons.
@@ -164,6 +182,36 @@ Provocative questions that might unlock better solutions:
- Prioritize ruthlessly. If everything is important, nothing is.
- Don't soften criticism. Developers need honest feedback to ship great design.
### Persist the Snapshot
Once the report above is finalized, write it to `.impeccable/critique/` so the user can refer back, and so `/impeccable polish` can pick up the priority issues without a copy-paste.
Skip this step if the Setup slug was null (vague or root-level target).
1. **Write the body to a temp file** so you can pipe it to the helper. Use the full report (heuristic table, anti-patterns verdict, priority issues, persona red flags) but stop before the "Ask the User" / "Recommended Actions" sections that come later.
2. **Pass the structured metadata** through `IMPECCABLE_CRITIQUE_META` (JSON), then run the write command:
```bash
IMPECCABLE_CRITIQUE_META='{"target":"<user phrasing>","total_score":<n>,"p0_count":<n>,"p1_count":<n>}' \
node .kiro/skills/impeccable/scripts/critique-storage.mjs write <slug> <body-file>
```
The helper prints the absolute path it wrote.
3. **Read the trend** for context:
```bash
node .kiro/skills/impeccable/scripts/critique-storage.mjs trend <slug> 5
```
This returns a JSON array of the last 5 frontmatter entries (including the one you just wrote).
4. **Append a single line to the user-visible output**, after the report and before the questions:
> **Trend for `<slug>` (last 5 runs): 24 → 28 → 32 → 29 → 32**
> Wrote `.impeccable/critique/<filename>`.
If this is the first run for the slug, the trend is just one score; say so: "First run for this target, no trend yet."
This is fire-and-forget. Do not show the user the helper's JSON output; only the human-readable trend line and the written path. Failures here should not block the rest of the flow; print the error and move on.
### Ask the User
**After presenting findings**, use targeted questions based on what was actually found. ask the user directly to clarify what you cannot infer. These answers will shape the action plan.

When polish time is tight, functional issues ship first; cosmetic ones can land in a follow-up. Quality should be consistent; never perfect one corner while leaving another rough.
4. **Pull in any prior critique** (optional signal): If `/impeccable critique` has been run on the same target, its priority issues are a useful prior for what to address first. Resolve the target to a file path or URL, then:

# Codex: Visual Direction & Asset Production
This file is loaded by `/impeccable craft` when the harness has native image generation (currently Codex via `image_gen`). Other harnesses skip it. It covers the two craft steps that depend on real image generation: landing the visual direction, and producing the raster assets the implementation will compose.
Read this *before* generating any images. The order matters, and the per-step user pauses are what keep generated imagery from drifting away from the brief.
## Step A: Explore Directions with the User
Before generating anything, run a brief direction conversation grounded in the shape brief.
Ask **2-3 targeted questions** about visual lane, color strategy, atmosphere, and named anchor references. Don't enumerate generic menus; tie each question to the shape brief's answers. Example shape-grounded questions:
- "Brief says 'editorial restraint, Klim-adjacent.' Are we closer to a quiet specimen page or a magazine-spread feel with hero imagery?"
- "Palette strategy from shape was 'Committed.' Want it warm-grounded (deep oxblood + cream) or cool-grounded (slate + paper white)?"
Stop and wait for answers. These pin the palette before any pixel gets generated.
## Step B: Generate the Brand Palette First
Generate **one** palette artifact before any mocks. This is a small, focused image: typography pairing on the chosen background, primary + accent color swatches, one signature ornament or motif. Single image, single pass.
Why palette first: mocks generated against a vague color sense produce noise that drowns out the structural decisions. A confirmed palette is the first concrete contract for everything downstream.
Show the palette to the user. Ask one question: "This is the palette I'm locking in for the mocks. Confirm, or call out what to shift?"
Wait for confirmation. Do not generate mocks against an unconfirmed palette.
## Step C: Generate 1-3 Visual Mocks Against the Palette
Once the palette is confirmed, generate **1 to 3** high-fidelity north-star comps. Each mock must use the confirmed palette and typography. Mocks differ in *structural* direction (hierarchy, topology, density, composition), not in color or motif.
- Brand work: push visual identity, composition, mood, and signature motifs.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
Use the `image_gen` tool directly (or via the imagegen skill when available). Don't ask the user to install anything.
## Step D: Approval Loop
Show the comps. Ask what carries forward. Iterate until **one direction is approved** or the user explicitly delegates.
If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before moving to assets, summarize what to carry into code and what *not* to literalize from the mock. This is the handoff between visual exploration and semantic implementation.
## Step E: Mock Fidelity Inventory
Inventory the approved mock's major visible ingredients. For each, decide implementation: semantic HTML/CSS/SVG, generated raster, sourced raster, icon library, canvas/WebGL, or accepted omission.
Common ingredients to inventory:
- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)
- 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
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.
If a photographic, architectural, product, or place-led mock becomes generic CSS scenery, decorative diagrams, bullets, or copy, stop and fix it. That's a broken implementation, not a harmless interpretation.
Don't substitute a different hero composition or visual driver post-approval without user sign-off.
## Step F: Asset Slicing via the Asset Producer
Raster ingredients identified in Step E need clean production assets. Use the bundled `impeccable_asset_producer` subagent rather than producing inline.
Spawn it as a scoped subagent. If you do not have explicit permission to use agents, stop and ask:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
Pass to the agent:
- Approved mock path or screenshot reference
- Crop paths or a contact sheet with crop ids
- Output directory
- Required dimensions, format, transparency needs
- Avoid list
- Notes on what should remain semantic HTML/CSS/SVG instead of raster
Attach image generation capability to the spawned agent when the harness supports it. Do **not** load image-generation reference material into the parent thread.
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.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; reach for real, generated, or stock imagery when the mock or subject matter calls for actual visual content.

## Step 3: Land the Visual Direction (Capability-Gated)
## Step 3: Visual Direction & Assets (Harness-Gated)
Generate high-fidelity visual comps before implementation when all three are true:
If the harness has **native image generation** (currently Codex via `image_gen`), this step is mandatory. **Stop and load [codex.md](codex.md)**. It covers palette generation, mock exploration, the approval loop, mock-fidelity inventory, and asset slicing via the `impeccable_asset_producer` subagent. Follow Steps A-F in that file, then return here for Step 4.
- 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.
If the harness lacks native image generation, **state in one line that the visual-direction-by-generation step is being skipped because the harness lacks native image generation, then proceed**. The one-line announcement is required; it forces a conscious decision instead of letting the step quietly evaporate. The brief is your only visual reference. Implement directly from it, treating any named anchor references and the brief's "Design Direction" as the contract.
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.
Whether you generated mocks or not: don't replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy. Image-led briefs (restaurants, hotels, magazines, photography, hobbyist communities, food, travel, fashion, product) need real or sourced imagery in the build, not CSS scenery.
### What to generate
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.
- Brand work: push visual identity, composition, and mood aggressively.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
### Approval loop
Show the comps and ask what carries forward. Iterate until one direction is approved or the user delegates. If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before Step 4, summarize what to carry into code and what **not** to literalize from the mock. This is the handoff between visual exploration and semantic implementation.
### Mock fidelity inventory
Inventory the approved mock's major visible ingredients:
- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)
- Nav and primary CTA treatment
- Section sequence, especially the second fold
- Image-native content the concept depends on

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 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.
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:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
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.
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.

> **Additional context needed**: what the interface is trying to accomplish.
### Setup: Resolve Target and Load Ignore List
Before gathering assessments, do two small bookkeeping steps. They cost almost nothing and they're what makes critique iterative across runs.
1. **Resolve the primary artifact.** The user's phrasing ("the homepage", "the pricing flow") is not stable enough to track across runs. Resolve it to a concrete file path or URL: the same one you'd already need to scan code or open in a browser. Examples:
- "the homepage" → `site/pages/index.astro` (or `http://localhost:3000/` if you're inspecting live)
- "the settings modal" → the primary component file (e.g., `src/components/Settings.tsx`)
- "this page" → the URL or the page's source file
Prefer the source file path over the dev-server URL when both exist; ports drift between runs (`bun dev` vs `bun preview`), file paths don't.
2. **Compute the slug.** Run:
```bash
node .opencode/skills/impeccable/scripts/critique-storage.mjs slug "<resolved-path-or-url>"
```
Keep the printed slug. It identifies this target's stream across runs. If the command exits non-zero ("no stable slug for input"), skip persistence for this run and tell the user; the trend won't update but the critique still goes ahead.
3. **Read the ignore list** at `.impeccable/critique/ignore.md` if it exists. Plain markdown; each non-empty, non-comment line is something the user has marked as "do not re-raise" (deferred tradeoffs, designer-intended deviations, detector false-positives the user accepts). When a finding's text matches a line here (case-insensitive substring against rule name or snippet), **drop it silently**. Do not mention it in the report. This is the ONLY input critique consumes from prior runs; anchoring on prior findings would defeat the point of independent assessment.
### Gather Assessments
Launch two independent assessments. **Neither may see the other's output.** This isolation is what makes the combined score honest. Running both in one head silently anchors them to each other; do not shortcut it for cost, speed, or context-size reasons.

- Prioritize ruthlessly. If everything is important, nothing is.
- Don't soften criticism. Developers need honest feedback to ship great design.
### Persist the Snapshot
Once the report above is finalized, write it to `.impeccable/critique/` so the user can refer back, and so `/impeccable polish` can pick up the priority issues without a copy-paste.
Skip this step if the Setup slug was null (vague or root-level target).
1. **Write the body to a temp file** so you can pipe it to the helper. Use the full report (heuristic table, anti-patterns verdict, priority issues, persona red flags) but stop before the "Ask the User" / "Recommended Actions" sections that come later.
2. **Pass the structured metadata** through `IMPECCABLE_CRITIQUE_META` (JSON), then run the write command:
```bash
IMPECCABLE_CRITIQUE_META='{"target":"<user phrasing>","total_score":<n>,"p0_count":<n>,"p1_count":<n>}' \
node .opencode/skills/impeccable/scripts/critique-storage.mjs write <slug> <body-file>
```
The helper prints the absolute path it wrote.
3. **Read the trend** for context:
```bash
node .opencode/skills/impeccable/scripts/critique-storage.mjs trend <slug> 5
```
This returns a JSON array of the last 5 frontmatter entries (including the one you just wrote).
4. **Append a single line to the user-visible output**, after the report and before the questions:
> **Trend for `<slug>` (last 5 runs): 24 → 28 → 32 → 29 → 32**
> Wrote `.impeccable/critique/<filename>`.
If this is the first run for the slug, the trend is just one score; say so: "First run for this target, no trend yet."
This is fire-and-forget. Do not show the user the helper's JSON output; only the human-readable trend line and the written path. Failures here should not block the rest of the flow; print the error and move on.

When polish time is tight, functional issues ship first; cosmetic ones can land in a follow-up. Quality should be consistent; never perfect one corner while leaving another rough.
4. **Pull in any prior critique** (optional signal): If `/impeccable critique` has been run on the same target, its priority issues are a useful prior for what to address first. Resolve the target to a file path or URL, then:
```bash

# Codex: Visual Direction & Asset Production
This file is loaded by `/impeccable craft` when the harness has native image generation (currently Codex via `image_gen`). Other harnesses skip it. It covers the two craft steps that depend on real image generation: landing the visual direction, and producing the raster assets the implementation will compose.
Read this *before* generating any images. The order matters, and the per-step user pauses are what keep generated imagery from drifting away from the brief.
## Step A: Explore Directions with the User
Before generating anything, run a brief direction conversation grounded in the shape brief.
Ask **2-3 targeted questions** about visual lane, color strategy, atmosphere, and named anchor references. Don't enumerate generic menus; tie each question to the shape brief's answers. Example shape-grounded questions:
- "Brief says 'editorial restraint, Klim-adjacent.' Are we closer to a quiet specimen page or a magazine-spread feel with hero imagery?"
- "Palette strategy from shape was 'Committed.' Want it warm-grounded (deep oxblood + cream) or cool-grounded (slate + paper white)?"
Stop and wait for answers. These pin the palette before any pixel gets generated.
## Step B: Generate the Brand Palette First
Generate **one** palette artifact before any mocks. This is a small, focused image: typography pairing on the chosen background, primary + accent color swatches, one signature ornament or motif. Single image, single pass.
Why palette first: mocks generated against a vague color sense produce noise that drowns out the structural decisions. A confirmed palette is the first concrete contract for everything downstream.
Show the palette to the user. Ask one question: "This is the palette I'm locking in for the mocks. Confirm, or call out what to shift?"
Wait for confirmation. Do not generate mocks against an unconfirmed palette.
## Step C: Generate 1-3 Visual Mocks Against the Palette
Once the palette is confirmed, generate **1 to 3** high-fidelity north-star comps. Each mock must use the confirmed palette and typography. Mocks differ in *structural* direction (hierarchy, topology, density, composition), not in color or motif.
- Brand work: push visual identity, composition, mood, and signature motifs.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
Use the `image_gen` tool directly (or via the imagegen skill when available). Don't ask the user to install anything.
## Step D: Approval Loop
Show the comps. Ask what carries forward. Iterate until **one direction is approved** or the user explicitly delegates.
If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before moving to assets, summarize what to carry into code and what *not* to literalize from the mock. This is the handoff between visual exploration and semantic implementation.
## Step E: Mock Fidelity Inventory
Inventory the approved mock's major visible ingredients. For each, decide implementation: semantic HTML/CSS/SVG, generated raster, sourced raster, icon library, canvas/WebGL, or accepted omission.
Common ingredients to inventory:
- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)
- 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
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.
If a photographic, architectural, product, or place-led mock becomes generic CSS scenery, decorative diagrams, bullets, or copy, stop and fix it. That's a broken implementation, not a harmless interpretation.
Don't substitute a different hero composition or visual driver post-approval without user sign-off.
## Step F: Asset Slicing via the Asset Producer
Raster ingredients identified in Step E need clean production assets. Use the bundled `impeccable_asset_producer` subagent rather than producing inline.
Spawn it as a scoped subagent. If you do not have explicit permission to use agents, stop and ask:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
Pass to the agent:
- Approved mock path or screenshot reference
- Crop paths or a contact sheet with crop ids
- Output directory
- Required dimensions, format, transparency needs
- Avoid list
- Notes on what should remain semantic HTML/CSS/SVG instead of raster
Attach image generation capability to the spawned agent when the harness supports it. Do **not** load image-generation reference material into the parent thread.
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.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; reach for real, generated, or stock imagery when the mock or subject matter calls for actual visual content.
## After This File
Once Steps A through F are complete, return to `craft.md` Step 5 (Build to Production Quality). The implementation builds against the confirmed palette, approved mock, and the assets the producer wrote.

## Step 3: Land the Visual Direction (Capability-Gated)
## Step 3: Visual Direction & Assets (Harness-Gated)
Generate high-fidelity visual comps before implementation when all three are true:
If the harness has **native image generation** (currently Codex via `image_gen`), this step is mandatory. **Stop and load [codex.md](codex.md)**. It covers palette generation, mock exploration, the approval loop, mock-fidelity inventory, and asset slicing via the `impeccable_asset_producer` subagent. Follow Steps A-F in that file, then return here for Step 4.
- 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.
If the harness lacks native image generation, **state in one line that the visual-direction-by-generation step is being skipped because the harness lacks native image generation, then proceed**. The one-line announcement is required; it forces a conscious decision instead of letting the step quietly evaporate. The brief is your only visual reference. Implement directly from it, treating any named anchor references and the brief's "Design Direction" as the contract.
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.
Whether you generated mocks or not: don't replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy. Image-led briefs (restaurants, hotels, magazines, photography, hobbyist communities, food, travel, fashion, product) need real or sourced imagery in the build, not CSS scenery.
### What to generate
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.
- Brand work: push visual identity, composition, and mood aggressively.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
### Approval loop
Show the comps and ask what carries forward. Iterate until one direction is approved or the user delegates. If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before Step 4, summarize what to carry into code and what **not** to literalize from the mock. This is the handoff between visual exploration and semantic implementation.

- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)

## Step 4: Asset Extraction (Need-Gated)
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.
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:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
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.
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.

> **Additional context needed**: what the interface is trying to accomplish.
### Setup: Resolve Target and Load Ignore List
Before gathering assessments, do two small bookkeeping steps. They cost almost nothing and they're what makes critique iterative across runs.
1. **Resolve the primary artifact.** The user's phrasing ("the homepage", "the pricing flow") is not stable enough to track across runs. Resolve it to a concrete file path or URL: the same one you'd already need to scan code or open in a browser. Examples:
- "the homepage" → `site/pages/index.astro` (or `http://localhost:3000/` if you're inspecting live)
- "the settings modal" → the primary component file (e.g., `src/components/Settings.tsx`)
- "this page" → the URL or the page's source file
Prefer the source file path over the dev-server URL when both exist; ports drift between runs (`bun dev` vs `bun preview`), file paths don't.
2. **Compute the slug.** Run:
```bash
node .pi/skills/impeccable/scripts/critique-storage.mjs slug "<resolved-path-or-url>"
```
Keep the printed slug. It identifies this target's stream across runs. If the command exits non-zero ("no stable slug for input"), skip persistence for this run and tell the user; the trend won't update but the critique still goes ahead.
3. **Read the ignore list** at `.impeccable/critique/ignore.md` if it exists. Plain markdown; each non-empty, non-comment line is something the user has marked as "do not re-raise" (deferred tradeoffs, designer-intended deviations, detector false-positives the user accepts). When a finding's text matches a line here (case-insensitive substring against rule name or snippet), **drop it silently**. Do not mention it in the report. This is the ONLY input critique consumes from prior runs; anchoring on prior findings would defeat the point of independent assessment.
### Gather Assessments
Launch two independent assessments. **Neither may see the other's output.** This isolation is what makes the combined score honest. Running both in one head silently anchors them to each other; do not shortcut it for cost, speed, or context-size reasons.
@@ -164,6 +182,36 @@ Provocative questions that might unlock better solutions:
- Prioritize ruthlessly. If everything is important, nothing is.
- Don't soften criticism. Developers need honest feedback to ship great design.
### Persist the Snapshot
Once the report above is finalized, write it to `.impeccable/critique/` so the user can refer back, and so `/impeccable polish` can pick up the priority issues without a copy-paste.
Skip this step if the Setup slug was null (vague or root-level target).
1. **Write the body to a temp file** so you can pipe it to the helper. Use the full report (heuristic table, anti-patterns verdict, priority issues, persona red flags) but stop before the "Ask the User" / "Recommended Actions" sections that come later.
2. **Pass the structured metadata** through `IMPECCABLE_CRITIQUE_META` (JSON), then run the write command:
```bash
IMPECCABLE_CRITIQUE_META='{"target":"<user phrasing>","total_score":<n>,"p0_count":<n>,"p1_count":<n>}' \
node .pi/skills/impeccable/scripts/critique-storage.mjs write <slug> <body-file>
```
The helper prints the absolute path it wrote.
3. **Read the trend** for context:
```bash
node .pi/skills/impeccable/scripts/critique-storage.mjs trend <slug> 5
```
This returns a JSON array of the last 5 frontmatter entries (including the one you just wrote).
4. **Append a single line to the user-visible output**, after the report and before the questions:
> **Trend for `<slug>` (last 5 runs): 24 → 28 → 32 → 29 → 32**
> Wrote `.impeccable/critique/<filename>`.
If this is the first run for the slug, the trend is just one score; say so: "First run for this target, no trend yet."
This is fire-and-forget. Do not show the user the helper's JSON output; only the human-readable trend line and the written path. Failures here should not block the rest of the flow; print the error and move on.
### Ask the User
**After presenting findings**, use targeted questions based on what was actually found. ask the user directly to clarify what you cannot infer. These answers will shape the action plan.

4. **Pull in any prior critique** (optional signal): If `/impeccable critique` has been run on the same target, its priority issues are a useful prior for what to address first. Resolve the target to a file path or URL, then:

# Codex: Visual Direction & Asset Production
This file is loaded by `/impeccable craft` when the harness has native image generation (currently Codex via `image_gen`). Other harnesses skip it. It covers the two craft steps that depend on real image generation: landing the visual direction, and producing the raster assets the implementation will compose.
Read this *before* generating any images. The order matters, and the per-step user pauses are what keep generated imagery from drifting away from the brief.
## Step A: Explore Directions with the User
Before generating anything, run a brief direction conversation grounded in the shape brief.
Ask **2-3 targeted questions** about visual lane, color strategy, atmosphere, and named anchor references. Don't enumerate generic menus; tie each question to the shape brief's answers. Example shape-grounded questions:
- "Brief says 'editorial restraint, Klim-adjacent.' Are we closer to a quiet specimen page or a magazine-spread feel with hero imagery?"
- "Palette strategy from shape was 'Committed.' Want it warm-grounded (deep oxblood + cream) or cool-grounded (slate + paper white)?"
Stop and wait for answers. These pin the palette before any pixel gets generated.
## Step B: Generate the Brand Palette First
Generate **one** palette artifact before any mocks. This is a small, focused image: typography pairing on the chosen background, primary + accent color swatches, one signature ornament or motif. Single image, single pass.
Why palette first: mocks generated against a vague color sense produce noise that drowns out the structural decisions. A confirmed palette is the first concrete contract for everything downstream.
Show the palette to the user. Ask one question: "This is the palette I'm locking in for the mocks. Confirm, or call out what to shift?"
Wait for confirmation. Do not generate mocks against an unconfirmed palette.
## Step C: Generate 1-3 Visual Mocks Against the Palette
Once the palette is confirmed, generate **1 to 3** high-fidelity north-star comps. Each mock must use the confirmed palette and typography. Mocks differ in *structural* direction (hierarchy, topology, density, composition), not in color or motif.
- Brand work: push visual identity, composition, mood, and signature motifs.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
Use the `image_gen` tool directly (or via the imagegen skill when available). Don't ask the user to install anything.
## Step D: Approval Loop
Show the comps. Ask what carries forward. Iterate until **one direction is approved** or the user explicitly delegates.
If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before moving to assets, summarize what to carry into code and what *not* to literalize from the mock. This is the handoff between visual exploration and semantic implementation.
## Step E: Mock Fidelity Inventory
Inventory the approved mock's major visible ingredients. For each, decide implementation: semantic HTML/CSS/SVG, generated raster, sourced raster, icon library, canvas/WebGL, or accepted omission.
Common ingredients to inventory:
- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)
- 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
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.
If a photographic, architectural, product, or place-led mock becomes generic CSS scenery, decorative diagrams, bullets, or copy, stop and fix it. That's a broken implementation, not a harmless interpretation.
Don't substitute a different hero composition or visual driver post-approval without user sign-off.
## Step F: Asset Slicing via the Asset Producer
Raster ingredients identified in Step E need clean production assets. Use the bundled `impeccable_asset_producer` subagent rather than producing inline.
Spawn it as a scoped subagent. If you do not have explicit permission to use agents, stop and ask:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
Pass to the agent:
- Approved mock path or screenshot reference
- Crop paths or a contact sheet with crop ids
- Output directory
- Required dimensions, format, transparency needs
- Avoid list
- Notes on what should remain semantic HTML/CSS/SVG instead of raster
Attach image generation capability to the spawned agent when the harness supports it. Do **not** load image-generation reference material into the parent thread.
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.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; reach for real, generated, or stock imagery when the mock or subject matter calls for actual visual content.

## Step 3: Land the Visual Direction (Capability-Gated)
## Step 3: Visual Direction & Assets (Harness-Gated)
Generate high-fidelity visual comps before implementation when all three are true:
If the harness has **native image generation** (currently Codex via `image_gen`), this step is mandatory. **Stop and load [codex.md](codex.md)**. It covers palette generation, mock exploration, the approval loop, mock-fidelity inventory, and asset slicing via the `impeccable_asset_producer` subagent. Follow Steps A-F in that file, then return here for Step 4.
- 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.
If the harness lacks native image generation, **state in one line that the visual-direction-by-generation step is being skipped because the harness lacks native image generation, then proceed**. The one-line announcement is required; it forces a conscious decision instead of letting the step quietly evaporate. The brief is your only visual reference. Implement directly from it, treating any named anchor references and the brief's "Design Direction" as the contract.
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.
Whether you generated mocks or not: don't replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy. Image-led briefs (restaurants, hotels, magazines, photography, hobbyist communities, food, travel, fashion, product) need real or sourced imagery in the build, not CSS scenery.
### What to generate
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.
- Brand work: push visual identity, composition, and mood aggressively.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
### Approval loop
Show the comps and ask what carries forward. Iterate until one direction is approved or the user delegates. If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before Step 4, summarize what to carry into code and what **not** to literalize from the mock. This is the handoff between visual exploration and semantic implementation.

- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)

## Step 4: Asset Extraction (Need-Gated)
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.
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:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
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.
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.

> **Additional context needed**: what the interface is trying to accomplish.
### Setup: Resolve Target and Load Ignore List
Before gathering assessments, do two small bookkeeping steps. They cost almost nothing and they're what makes critique iterative across runs.
1. **Resolve the primary artifact.** The user's phrasing ("the homepage", "the pricing flow") is not stable enough to track across runs. Resolve it to a concrete file path or URL: the same one you'd already need to scan code or open in a browser. Examples:
- "the homepage" → `site/pages/index.astro` (or `http://localhost:3000/` if you're inspecting live)
- "the settings modal" → the primary component file (e.g., `src/components/Settings.tsx`)
- "this page" → the URL or the page's source file
Prefer the source file path over the dev-server URL when both exist; ports drift between runs (`bun dev` vs `bun preview`), file paths don't.
2. **Compute the slug.** Run:
```bash
node .qoder/skills/impeccable/scripts/critique-storage.mjs slug "<resolved-path-or-url>"
```
Keep the printed slug. It identifies this target's stream across runs. If the command exits non-zero ("no stable slug for input"), skip persistence for this run and tell the user; the trend won't update but the critique still goes ahead.
3. **Read the ignore list** at `.impeccable/critique/ignore.md` if it exists. Plain markdown; each non-empty, non-comment line is something the user has marked as "do not re-raise" (deferred tradeoffs, designer-intended deviations, detector false-positives the user accepts). When a finding's text matches a line here (case-insensitive substring against rule name or snippet), **drop it silently**. Do not mention it in the report. This is the ONLY input critique consumes from prior runs; anchoring on prior findings would defeat the point of independent assessment.
### Gather Assessments
Launch two independent assessments. **Neither may see the other's output.** This isolation is what makes the combined score honest. Running both in one head silently anchors them to each other; do not shortcut it for cost, speed, or context-size reasons.
@@ -164,6 +182,36 @@ Provocative questions that might unlock better solutions:
- Prioritize ruthlessly. If everything is important, nothing is.
- Don't soften criticism. Developers need honest feedback to ship great design.
### Persist the Snapshot
Once the report above is finalized, write it to `.impeccable/critique/` so the user can refer back, and so `/impeccable polish` can pick up the priority issues without a copy-paste.
Skip this step if the Setup slug was null (vague or root-level target).
1. **Write the body to a temp file** so you can pipe it to the helper. Use the full report (heuristic table, anti-patterns verdict, priority issues, persona red flags) but stop before the "Ask the User" / "Recommended Actions" sections that come later.
2. **Pass the structured metadata** through `IMPECCABLE_CRITIQUE_META` (JSON), then run the write command:
```bash
IMPECCABLE_CRITIQUE_META='{"target":"<user phrasing>","total_score":<n>,"p0_count":<n>,"p1_count":<n>}' \
node .qoder/skills/impeccable/scripts/critique-storage.mjs write <slug> <body-file>
```
The helper prints the absolute path it wrote.
3. **Read the trend** for context:
```bash
node .qoder/skills/impeccable/scripts/critique-storage.mjs trend <slug> 5
```
This returns a JSON array of the last 5 frontmatter entries (including the one you just wrote).
4. **Append a single line to the user-visible output**, after the report and before the questions:
> **Trend for `<slug>` (last 5 runs): 24 → 28 → 32 → 29 → 32**
> Wrote `.impeccable/critique/<filename>`.
If this is the first run for the slug, the trend is just one score; say so: "First run for this target, no trend yet."
This is fire-and-forget. Do not show the user the helper's JSON output; only the human-readable trend line and the written path. Failures here should not block the rest of the flow; print the error and move on.
### Ask the User
**After presenting findings**, use targeted questions based on what was actually found. ask the user directly to clarify what you cannot infer. These answers will shape the action plan.

4. **Pull in any prior critique** (optional signal): If `/impeccable critique` has been run on the same target, its priority issues are a useful prior for what to address first. Resolve the target to a file path or URL, then:

# Codex: Visual Direction & Asset Production
This file is loaded by `/impeccable craft` when the harness has native image generation (currently Codex via `image_gen`). Other harnesses skip it. It covers the two craft steps that depend on real image generation: landing the visual direction, and producing the raster assets the implementation will compose.
Read this *before* generating any images. The order matters, and the per-step user pauses are what keep generated imagery from drifting away from the brief.
## Step A: Explore Directions with the User
Before generating anything, run a brief direction conversation grounded in the shape brief.
Ask **2-3 targeted questions** about visual lane, color strategy, atmosphere, and named anchor references. Don't enumerate generic menus; tie each question to the shape brief's answers. Example shape-grounded questions:
- "Brief says 'editorial restraint, Klim-adjacent.' Are we closer to a quiet specimen page or a magazine-spread feel with hero imagery?"
- "Palette strategy from shape was 'Committed.' Want it warm-grounded (deep oxblood + cream) or cool-grounded (slate + paper white)?"
Stop and wait for answers. These pin the palette before any pixel gets generated.
## Step B: Generate the Brand Palette First
Generate **one** palette artifact before any mocks. This is a small, focused image: typography pairing on the chosen background, primary + accent color swatches, one signature ornament or motif. Single image, single pass.
Why palette first: mocks generated against a vague color sense produce noise that drowns out the structural decisions. A confirmed palette is the first concrete contract for everything downstream.
Show the palette to the user. Ask one question: "This is the palette I'm locking in for the mocks. Confirm, or call out what to shift?"
Wait for confirmation. Do not generate mocks against an unconfirmed palette.
## Step C: Generate 1-3 Visual Mocks Against the Palette
Once the palette is confirmed, generate **1 to 3** high-fidelity north-star comps. Each mock must use the confirmed palette and typography. Mocks differ in *structural* direction (hierarchy, topology, density, composition), not in color or motif.
- Brand work: push visual identity, composition, mood, and signature motifs.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
Use the `image_gen` tool directly (or via the imagegen skill when available). Don't ask the user to install anything.
## Step D: Approval Loop
Show the comps. Ask what carries forward. Iterate until **one direction is approved** or the user explicitly delegates.
If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before moving to assets, summarize what to carry into code and what *not* to literalize from the mock. This is the handoff between visual exploration and semantic implementation.
## Step E: Mock Fidelity Inventory
Inventory the approved mock's major visible ingredients. For each, decide implementation: semantic HTML/CSS/SVG, generated raster, sourced raster, icon library, canvas/WebGL, or accepted omission.
Common ingredients to inventory:
- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)
- 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
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.
If a photographic, architectural, product, or place-led mock becomes generic CSS scenery, decorative diagrams, bullets, or copy, stop and fix it. That's a broken implementation, not a harmless interpretation.
Don't substitute a different hero composition or visual driver post-approval without user sign-off.
## Step F: Asset Slicing via the Asset Producer
Raster ingredients identified in Step E need clean production assets. Use the bundled `impeccable_asset_producer` subagent rather than producing inline.
Spawn it as a scoped subagent. If you do not have explicit permission to use agents, stop and ask:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
Pass to the agent:
- Approved mock path or screenshot reference
- Crop paths or a contact sheet with crop ids
- Output directory
- Required dimensions, format, transparency needs
- Avoid list
- Notes on what should remain semantic HTML/CSS/SVG instead of raster
Attach image generation capability to the spawned agent when the harness supports it. Do **not** load image-generation reference material into the parent thread.
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.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; reach for real, generated, or stock imagery when the mock or subject matter calls for actual visual content.

## Step 3: Land the Visual Direction (Capability-Gated)
## Step 3: Visual Direction & Assets (Harness-Gated)
Generate high-fidelity visual comps before implementation when all three are true:
If the harness has **native image generation** (currently Codex via `image_gen`), this step is mandatory. **Stop and load [codex.md](codex.md)**. It covers palette generation, mock exploration, the approval loop, mock-fidelity inventory, and asset slicing via the `impeccable_asset_producer` subagent. Follow Steps A-F in that file, then return here for Step 4.
- 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.
If the harness lacks native image generation, **state in one line that the visual-direction-by-generation step is being skipped because the harness lacks native image generation, then proceed**. The one-line announcement is required; it forces a conscious decision instead of letting the step quietly evaporate. The brief is your only visual reference. Implement directly from it, treating any named anchor references and the brief's "Design Direction" as the contract.
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.
Whether you generated mocks or not: don't replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy. Image-led briefs (restaurants, hotels, magazines, photography, hobbyist communities, food, travel, fashion, product) need real or sourced imagery in the build, not CSS scenery.
### What to generate
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.
- Brand work: push visual identity, composition, and mood aggressively.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
### Approval loop
Show the comps and ask what carries forward. Iterate until one direction is approved or the user delegates. If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before Step 4, summarize what to carry into code and what **not** to literalize from the mock. This is the handoff between visual exploration and semantic implementation.

- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)

## Step 4: Asset Extraction (Need-Gated)
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.
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:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
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.
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.

### Setup: Resolve Target and Load Ignore List
Before gathering assessments, do two small bookkeeping steps. They cost almost nothing and they're what makes critique iterative across runs.
1. **Resolve the primary artifact.** The user's phrasing ("the homepage", "the pricing flow") is not stable enough to track across runs. Resolve it to a concrete file path or URL: the same one you'd already need to scan code or open in a browser. Examples:
- "the homepage" → `site/pages/index.astro` (or `http://localhost:3000/` if you're inspecting live)
- "the settings modal" → the primary component file (e.g., `src/components/Settings.tsx`)
- "this page" → the URL or the page's source file
Prefer the source file path over the dev-server URL when both exist; ports drift between runs (`bun dev` vs `bun preview`), file paths don't.
2. **Compute the slug.** Run:
```bash
node .rovodev/skills/impeccable/scripts/critique-storage.mjs slug "<resolved-path-or-url>"
```
Keep the printed slug. It identifies this target's stream across runs. If the command exits non-zero ("no stable slug for input"), skip persistence for this run and tell the user; the trend won't update but the critique still goes ahead.
3. **Read the ignore list** at `.impeccable/critique/ignore.md` if it exists. Plain markdown; each non-empty, non-comment line is something the user has marked as "do not re-raise" (deferred tradeoffs, designer-intended deviations, detector false-positives the user accepts). When a finding's text matches a line here (case-insensitive substring against rule name or snippet), **drop it silently**. Do not mention it in the report. This is the ONLY input critique consumes from prior runs; anchoring on prior findings would defeat the point of independent assessment.
### Gather Assessments
Launch two independent assessments. **Neither may see the other's output.** This isolation is what makes the combined score honest. Running both in one head silently anchors them to each other; do not shortcut it for cost, speed, or context-size reasons.

- Prioritize ruthlessly. If everything is important, nothing is.
- Don't soften criticism. Developers need honest feedback to ship great design.
### Persist the Snapshot
Once the report above is finalized, write it to `.impeccable/critique/` so the user can refer back, and so `/impeccable polish` can pick up the priority issues without a copy-paste.
Skip this step if the Setup slug was null (vague or root-level target).
1. **Write the body to a temp file** so you can pipe it to the helper. Use the full report (heuristic table, anti-patterns verdict, priority issues, persona red flags) but stop before the "Ask the User" / "Recommended Actions" sections that come later.
2. **Pass the structured metadata** through `IMPECCABLE_CRITIQUE_META` (JSON), then run the write command:
```bash
IMPECCABLE_CRITIQUE_META='{"target":"<user phrasing>","total_score":<n>,"p0_count":<n>,"p1_count":<n>}' \
node .rovodev/skills/impeccable/scripts/critique-storage.mjs write <slug> <body-file>
```
The helper prints the absolute path it wrote.
3. **Read the trend** for context:
```bash
node .rovodev/skills/impeccable/scripts/critique-storage.mjs trend <slug> 5
```
This returns a JSON array of the last 5 frontmatter entries (including the one you just wrote).
4. **Append a single line to the user-visible output**, after the report and before the questions:
> **Trend for `<slug>` (last 5 runs): 24 → 28 → 32 → 29 → 32**
> Wrote `.impeccable/critique/<filename>`.
If this is the first run for the slug, the trend is just one score; say so: "First run for this target, no trend yet."
This is fire-and-forget. Do not show the user the helper's JSON output; only the human-readable trend line and the written path. Failures here should not block the rest of the flow; print the error and move on.

When polish time is tight, functional issues ship first; cosmetic ones can land in a follow-up. Quality should be consistent; never perfect one corner while leaving another rough.
4. **Pull in any prior critique** (optional signal): If `/impeccable critique` has been run on the same target, its priority issues are a useful prior for what to address first. Resolve the target to a file path or URL, then:

# Codex: Visual Direction & Asset Production
This file is loaded by `/impeccable craft` when the harness has native image generation (currently Codex via `image_gen`). Other harnesses skip it. It covers the two craft steps that depend on real image generation: landing the visual direction, and producing the raster assets the implementation will compose.
Read this *before* generating any images. The order matters, and the per-step user pauses are what keep generated imagery from drifting away from the brief.
## Step A: Explore Directions with the User
Before generating anything, run a brief direction conversation grounded in the shape brief.
Ask **2-3 targeted questions** about visual lane, color strategy, atmosphere, and named anchor references. Don't enumerate generic menus; tie each question to the shape brief's answers. Example shape-grounded questions:
- "Brief says 'editorial restraint, Klim-adjacent.' Are we closer to a quiet specimen page or a magazine-spread feel with hero imagery?"
- "Palette strategy from shape was 'Committed.' Want it warm-grounded (deep oxblood + cream) or cool-grounded (slate + paper white)?"
Stop and wait for answers. These pin the palette before any pixel gets generated.
## Step B: Generate the Brand Palette First
Generate **one** palette artifact before any mocks. This is a small, focused image: typography pairing on the chosen background, primary + accent color swatches, one signature ornament or motif. Single image, single pass.
Why palette first: mocks generated against a vague color sense produce noise that drowns out the structural decisions. A confirmed palette is the first concrete contract for everything downstream.
Show the palette to the user. Ask one question: "This is the palette I'm locking in for the mocks. Confirm, or call out what to shift?"
Wait for confirmation. Do not generate mocks against an unconfirmed palette.
## Step C: Generate 1-3 Visual Mocks Against the Palette
Once the palette is confirmed, generate **1 to 3** high-fidelity north-star comps. Each mock must use the confirmed palette and typography. Mocks differ in *structural* direction (hierarchy, topology, density, composition), not in color or motif.
- Brand work: push visual identity, composition, mood, and signature motifs.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
Use the `image_gen` tool directly (or via the imagegen skill when available). Don't ask the user to install anything.
## Step D: Approval Loop
Show the comps. Ask what carries forward. Iterate until **one direction is approved** or the user explicitly delegates.
If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before moving to assets, summarize what to carry into code and what *not* to literalize from the mock. This is the handoff between visual exploration and semantic implementation.
## Step E: Mock Fidelity Inventory
Inventory the approved mock's major visible ingredients. For each, decide implementation: semantic HTML/CSS/SVG, generated raster, sourced raster, icon library, canvas/WebGL, or accepted omission.
Common ingredients to inventory:
- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)
- 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
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.
If a photographic, architectural, product, or place-led mock becomes generic CSS scenery, decorative diagrams, bullets, or copy, stop and fix it. That's a broken implementation, not a harmless interpretation.
Don't substitute a different hero composition or visual driver post-approval without user sign-off.
## Step F: Asset Slicing via the Asset Producer
Raster ingredients identified in Step E need clean production assets. Use the bundled `impeccable_asset_producer` subagent rather than producing inline.
Spawn it as a scoped subagent. If you do not have explicit permission to use agents, stop and ask:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
Pass to the agent:
- Approved mock path or screenshot reference
- Crop paths or a contact sheet with crop ids
- Output directory
- Required dimensions, format, transparency needs
- Avoid list
- Notes on what should remain semantic HTML/CSS/SVG instead of raster
Attach image generation capability to the spawned agent when the harness supports it. Do **not** load image-generation reference material into the parent thread.
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.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; reach for real, generated, or stock imagery when the mock or subject matter calls for actual visual content.

## Step 3: Land the Visual Direction (Capability-Gated)
## Step 3: Visual Direction & Assets (Harness-Gated)
Generate high-fidelity visual comps before implementation when all three are true:
If the harness has **native image generation** (currently Codex via `image_gen`), this step is mandatory. **Stop and load [codex.md](codex.md)**. It covers palette generation, mock exploration, the approval loop, mock-fidelity inventory, and asset slicing via the `impeccable_asset_producer` subagent. Follow Steps A-F in that file, then return here for Step 4.
- 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.
If the harness lacks native image generation, **state in one line that the visual-direction-by-generation step is being skipped because the harness lacks native image generation, then proceed**. The one-line announcement is required; it forces a conscious decision instead of letting the step quietly evaporate. The brief is your only visual reference. Implement directly from it, treating any named anchor references and the brief's "Design Direction" as the contract.
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.
Whether you generated mocks or not: don't replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy. Image-led briefs (restaurants, hotels, magazines, photography, hobbyist communities, food, travel, fashion, product) need real or sourced imagery in the build, not CSS scenery.
### What to generate
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.
- Brand work: push visual identity, composition, and mood aggressively.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
### Approval loop
Show the comps and ask what carries forward. Iterate until one direction is approved or the user delegates. If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before Step 4, summarize what to carry into code and what **not** to literalize from the mock. This is the handoff between visual exploration and semantic implementation.

- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)

## Step 4: Asset Extraction (Need-Gated)
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.
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:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
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.
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.

### Setup: Resolve Target and Load Ignore List
Before gathering assessments, do two small bookkeeping steps. They cost almost nothing and they're what makes critique iterative across runs.
1. **Resolve the primary artifact.** The user's phrasing ("the homepage", "the pricing flow") is not stable enough to track across runs. Resolve it to a concrete file path or URL: the same one you'd already need to scan code or open in a browser. Examples:
- "the homepage" → `site/pages/index.astro` (or `http://localhost:3000/` if you're inspecting live)
- "the settings modal" → the primary component file (e.g., `src/components/Settings.tsx`)
- "this page" → the URL or the page's source file
Prefer the source file path over the dev-server URL when both exist; ports drift between runs (`bun dev` vs `bun preview`), file paths don't.
2. **Compute the slug.** Run:
```bash
node .trae-cn/skills/impeccable/scripts/critique-storage.mjs slug "<resolved-path-or-url>"
```
Keep the printed slug. It identifies this target's stream across runs. If the command exits non-zero ("no stable slug for input"), skip persistence for this run and tell the user; the trend won't update but the critique still goes ahead.
3. **Read the ignore list** at `.impeccable/critique/ignore.md` if it exists. Plain markdown; each non-empty, non-comment line is something the user has marked as "do not re-raise" (deferred tradeoffs, designer-intended deviations, detector false-positives the user accepts). When a finding's text matches a line here (case-insensitive substring against rule name or snippet), **drop it silently**. Do not mention it in the report. This is the ONLY input critique consumes from prior runs; anchoring on prior findings would defeat the point of independent assessment.
### Gather Assessments
Launch two independent assessments. **Neither may see the other's output.** This isolation is what makes the combined score honest. Running both in one head silently anchors them to each other; do not shortcut it for cost, speed, or context-size reasons.

- Prioritize ruthlessly. If everything is important, nothing is.
- Don't soften criticism. Developers need honest feedback to ship great design.
### Persist the Snapshot
Once the report above is finalized, write it to `.impeccable/critique/` so the user can refer back, and so `/impeccable polish` can pick up the priority issues without a copy-paste.
Skip this step if the Setup slug was null (vague or root-level target).
1. **Write the body to a temp file** so you can pipe it to the helper. Use the full report (heuristic table, anti-patterns verdict, priority issues, persona red flags) but stop before the "Ask the User" / "Recommended Actions" sections that come later.
2. **Pass the structured metadata** through `IMPECCABLE_CRITIQUE_META` (JSON), then run the write command:
```bash
IMPECCABLE_CRITIQUE_META='{"target":"<user phrasing>","total_score":<n>,"p0_count":<n>,"p1_count":<n>}' \
node .trae-cn/skills/impeccable/scripts/critique-storage.mjs write <slug> <body-file>
```
The helper prints the absolute path it wrote.
3. **Read the trend** for context:
```bash
node .trae-cn/skills/impeccable/scripts/critique-storage.mjs trend <slug> 5
```
This returns a JSON array of the last 5 frontmatter entries (including the one you just wrote).
4. **Append a single line to the user-visible output**, after the report and before the questions:
> **Trend for `<slug>` (last 5 runs): 24 → 28 → 32 → 29 → 32**
> Wrote `.impeccable/critique/<filename>`.
If this is the first run for the slug, the trend is just one score; say so: "First run for this target, no trend yet."
This is fire-and-forget. Do not show the user the helper's JSON output; only the human-readable trend line and the written path. Failures here should not block the rest of the flow; print the error and move on.

4. **Pull in any prior critique** (optional signal): If `/impeccable critique` has been run on the same target, its priority issues are a useful prior for what to address first. Resolve the target to a file path or URL, then:

# Codex: Visual Direction & Asset Production
This file is loaded by `/impeccable craft` when the harness has native image generation (currently Codex via `image_gen`). Other harnesses skip it. It covers the two craft steps that depend on real image generation: landing the visual direction, and producing the raster assets the implementation will compose.
Read this *before* generating any images. The order matters, and the per-step user pauses are what keep generated imagery from drifting away from the brief.
## Step A: Explore Directions with the User
Before generating anything, run a brief direction conversation grounded in the shape brief.
Ask **2-3 targeted questions** about visual lane, color strategy, atmosphere, and named anchor references. Don't enumerate generic menus; tie each question to the shape brief's answers. Example shape-grounded questions:
- "Brief says 'editorial restraint, Klim-adjacent.' Are we closer to a quiet specimen page or a magazine-spread feel with hero imagery?"
- "Palette strategy from shape was 'Committed.' Want it warm-grounded (deep oxblood + cream) or cool-grounded (slate + paper white)?"
Stop and wait for answers. These pin the palette before any pixel gets generated.
## Step B: Generate the Brand Palette First
Generate **one** palette artifact before any mocks. This is a small, focused image: typography pairing on the chosen background, primary + accent color swatches, one signature ornament or motif. Single image, single pass.
Why palette first: mocks generated against a vague color sense produce noise that drowns out the structural decisions. A confirmed palette is the first concrete contract for everything downstream.
Show the palette to the user. Ask one question: "This is the palette I'm locking in for the mocks. Confirm, or call out what to shift?"
Wait for confirmation. Do not generate mocks against an unconfirmed palette.
## Step C: Generate 1-3 Visual Mocks Against the Palette
Once the palette is confirmed, generate **1 to 3** high-fidelity north-star comps. Each mock must use the confirmed palette and typography. Mocks differ in *structural* direction (hierarchy, topology, density, composition), not in color or motif.
- Brand work: push visual identity, composition, mood, and signature motifs.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
Use the `image_gen` tool directly (or via the imagegen skill when available). Don't ask the user to install anything.
## Step D: Approval Loop
Show the comps. Ask what carries forward. Iterate until **one direction is approved** or the user explicitly delegates.
If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before moving to assets, summarize what to carry into code and what *not* to literalize from the mock. This is the handoff between visual exploration and semantic implementation.
## Step E: Mock Fidelity Inventory
Inventory the approved mock's major visible ingredients. For each, decide implementation: semantic HTML/CSS/SVG, generated raster, sourced raster, icon library, canvas/WebGL, or accepted omission.
Common ingredients to inventory:
- Hero silhouette and dominant composition
- Signature motifs (planets, devices, portraits, charts, route lines, insets, badges, etc.)
- 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
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.
If a photographic, architectural, product, or place-led mock becomes generic CSS scenery, decorative diagrams, bullets, or copy, stop and fix it. That's a broken implementation, not a harmless interpretation.
Don't substitute a different hero composition or visual driver post-approval without user sign-off.
## Step F: Asset Slicing via the Asset Producer
Raster ingredients identified in Step E need clean production assets. Use the bundled `impeccable_asset_producer` subagent rather than producing inline.
Spawn it as a scoped subagent. If you do not have explicit permission to use agents, stop and ask:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
Pass to the agent:
- Approved mock path or screenshot reference
- Crop paths or a contact sheet with crop ids
- Output directory
- Required dimensions, format, transparency needs
- Avoid list
- Notes on what should remain semantic HTML/CSS/SVG instead of raster
Attach image generation capability to the spawned agent when the harness supports it. Do **not** load image-generation reference material into the parent thread.
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.
Prefer HTML/CSS/SVG/canvas when they can credibly reproduce an ingredient; reach for real, generated, or stock imagery when the mock or subject matter calls for actual visual content.

## Step 3: Land the Visual Direction (Capability-Gated)
## Step 3: Visual Direction & Assets (Harness-Gated)
Generate high-fidelity visual comps before implementation when all three are true:
If the harness has **native image generation** (currently Codex via `image_gen`), this step is mandatory. **Stop and load [codex.md](codex.md)**. It covers palette generation, mock exploration, the approval loop, mock-fidelity inventory, and asset slicing via the `impeccable_asset_producer` subagent. Follow Steps A-F in that file, then return here for Step 4.
- 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.
If the harness lacks native image generation, **state in one line that the visual-direction-by-generation step is being skipped because the harness lacks native image generation, then proceed**. The one-line announcement is required; it forces a conscious decision instead of letting the step quietly evaporate. The brief is your only visual reference. Implement directly from it, treating any named anchor references and the brief's "Design Direction" as the contract.
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.
Whether you generated mocks or not: don't replace required imagery with generic cards, bullets, emoji, fake metrics, decorative CSS panels, or filler copy. Image-led briefs (restaurants, hotels, magazines, photography, hobbyist communities, food, travel, fashion, product) need real or sourced imagery in the build, not CSS scenery.
### What to generate
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.
- Brand work: push visual identity, composition, and mood aggressively.
- Product work: push hierarchy, topology, density, tone, grounded in realistic product structure.
- Landing pages and long-form brand surfaces: show enough of the second fold to establish the system beyond the hero.
### Approval loop
Show the comps and ask what carries forward. Iterate until one direction is approved or the user delegates. If the user delegates, pick the strongest direction and explain it from the brief, not personal taste.
Before Step 4, summarize what to carry into code and what **not** to literalize from the mock. This is the handoff between visual exploration and semantic implementation.

- Hero silhouette and dominant composition

## Step 4: Asset Extraction (Need-Gated)
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.
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:
```text
Asset production will work better as a scoped subagent job. Should I spawn the Impeccable asset producer subagent for this step?
```
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.
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.

> **Additional context needed**: what the interface is trying to accomplish.
### Setup: Resolve Target and Load Ignore List
Before gathering assessments, do two small bookkeeping steps. They cost almost nothing and they're what makes critique iterative across runs.
1. **Resolve the primary artifact.** The user's phrasing ("the homepage", "the pricing flow") is not stable enough to track across runs. Resolve it to a concrete file path or URL: the same one you'd already need to scan code or open in a browser. Examples:
- "the homepage" → `site/pages/index.astro` (or `http://localhost:3000/` if you're inspecting live)
- "the settings modal" → the primary component file (e.g., `src/components/Settings.tsx`)
- "this page" → the URL or the page's source file
Prefer the source file path over the dev-server URL when both exist; ports drift between runs (`bun dev` vs `bun preview`), file paths don't.
2. **Compute the slug.** Run:
```bash
node .trae/skills/impeccable/scripts/critique-storage.mjs slug "<resolved-path-or-url>"
```
Keep the printed slug. It identifies this target's stream across runs. If the command exits non-zero ("no stable slug for input"), skip persistence for this run and tell the user; the trend won't update but the critique still goes ahead.
3. **Read the ignore list** at `.impeccable/critique/ignore.md` if it exists. Plain markdown; each non-empty, non-comment line is something the user has marked as "do not re-raise" (deferred tradeoffs, designer-intended deviations, detector false-positives the user accepts). When a finding's text matches a line here (case-insensitive substring against rule name or snippet), **drop it silently**. Do not mention it in the report. This is the ONLY input critique consumes from prior runs; anchoring on prior findings would defeat the point of independent assessment.
### Gather Assessments
Launch two independent assessments. **Neither may see the other's output.** This isolation is what makes the combined score honest. Running both in one head silently anchors them to each other; do not shortcut it for cost, speed, or context-size reasons.
@@ -164,6 +182,36 @@ Provocative questions that might unlock better solutions:
- Prioritize ruthlessly. If everything is important, nothing is.
- Don't soften criticism. Developers need honest feedback to ship great design.
### Persist the Snapshot
Once the report above is finalized, write it to `.impeccable/critique/` so the user can refer back, and so `/impeccable polish` can pick up the priority issues without a copy-paste.
Skip this step if the Setup slug was null (vague or root-level target).
1. **Write the body to a temp file** so you can pipe it to the helper. Use the full report (heuristic table, anti-patterns verdict, priority issues, persona red flags) but stop before the "Ask the User" / "Recommended Actions" sections that come later.
2. **Pass the structured metadata** through `IMPECCABLE_CRITIQUE_META` (JSON), then run the write command:
```bash
IMPECCABLE_CRITIQUE_META='{"target":"<user phrasing>","total_score":<n>,"p0_count":<n>,"p1_count":<n>}' \
node .trae/skills/impeccable/scripts/critique-storage.mjs write <slug> <body-file>
```
The helper prints the absolute path it wrote.
3. **Read the trend** for context:
```bash
node .trae/skills/impeccable/scripts/critique-storage.mjs trend <slug> 5
```
This returns a JSON array of the last 5 frontmatter entries (including the one you just wrote).
4. **Append a single line to the user-visible output**, after the report and before the questions:
> **Trend for `<slug>` (last 5 runs): 24 → 28 → 32 → 29 → 32**
> Wrote `.impeccable/critique/<filename>`.
If this is the first run for the slug, the trend is just one score; say so: "First run for this target, no trend yet."
This is fire-and-forget. Do not show the user the helper's JSON output; only the human-readable trend line and the written path. Failures here should not block the rest of the flow; print the error and move on.
### Ask the User
**After presenting findings**, use targeted questions based on what was actually found. ask the user directly to clarify what you cannot infer. These answers will shape the action plan.
