Adds a coarse-controls ("Tune") popover that slides out from behind the
contextual bar via clip-path, showing 2-4 per-variant knobs (range / steps /
toggle) driven by a `data-impeccable-params` manifest. Range/toggle drive
CSS custom properties on the variant wrapper; steps toggle a data
attribute. Values reset per variant; on accept, current values are passed
through live-poll to live-accept as an `impeccable-param-values` comment
for the carbonize cleanup step to bake in.
Other live-UI work in this change:
- Theme-aware palette (barPaletteForTheme) now drives the contextual bar,
action picker, and tune popover. Dark sand on light pages, paper on
dark. Detection has a localStorage dev override for QA.
- Action picker chips get inline SVG icons (wand / bars / funnel / sparkle /
type ramp / circles / grid / devices / curve / star / bolt) stacked
above the label; selection state recolors via currentColor.
- Accept button switched to saturated site magenta with paper text.
- Cycle dots reworked: solid accent for active, neutral for arrived,
hairline ring for pending. No more magenta-on-gray noise.
- Tune chip sits in the cycling row with a count pill badge; open state
uses accentSoft bg + accent text (no ad-hoc white border).
- Popover uses the bar's palette with a deeper surface (surfaceDeep),
lives behind the bar via z-index so a 6px overlap reads as tucked under
it, and animates with clip-path inset() for reliable slide behavior.

Pioneers a two-file convention for project context:
- PRODUCT.md (strategic): users, brand, principles — answers who/what/why
- DESIGN.md (visual): follows Google's Stitch DESIGN.md spec — answers how-it-looks
Both files live at the repo root. Filename matching is case-insensitive.
DESIGN.md wins on visual conflicts, PRODUCT.md wins on strategic/voice.
Legacy .impeccable.md is auto-migrated to PRODUCT.md on first read by the
new shared loader. This is silent and one-shot — the rename is permanent.
What changed:
- New scripts/load-context.mjs: shared context loader used by every command
that needs project context. Reads both files, handles legacy migration.
- New reference/document.md: /impeccable document command that generates
DESIGN.md by auto-extracting tokens (colors, typography, spacing, radii,
shadows, components) from CSS/Tailwind/theme files, then asking the user
to confirm descriptive language for atmosphere and color character.
Follows Google's Stitch DESIGN.md format for tool compatibility.
- SKILL.md Context Gathering Protocol updated to load both files and
nudge the user to run /impeccable document when DESIGN.md is missing.
- reference/teach.md rewritten to split discovery cleanly: strategic
questions go to PRODUCT.md, visual/design-system work is delegated to
/impeccable document (skipped on empty projects).
- reference/live.md consumes {product, design, productPath, designPath,
migrated} from the loader instead of a single context blob.
- scripts/live.mjs uses the shared loader instead of inline file reading.
- Command count updated 22 → 23 (new: document). Metadata, router table,
command menu, periodic table viz, and homepage data all updated.
- .gitignore adds PRODUCT.md + DESIGN.md (repo-local, not shared).

New feature: /impeccable live starts an interactive visual iteration server.
Users select elements in the browser, pick a design action (bolder, quieter,
etc.), and the agent generates HTML+CSS variants written directly to source.
The dev server's HMR hot-swaps them in, and MutationObserver progressively
reveals each variant in a cycler UI as it arrives.
Architecture:
- src/live/server.mjs: HTTP + WebSocket server with session token auth,
long-poll /poll endpoint for the agent, WebSocket for the browser
- src/live/poll.mjs: CLI client (npx impeccable poll / poll --reply)
- src/live/browser.js: element picker with keyboard nav (arrows=siblings,
shift+arrows=parent/child), action panel (12 commands, freeform input,
variant count), variant cycler with progressive reveal via MutationObserver
- src/live/protocol.mjs: shared message types and event validation
- source/skills/impeccable/reference/live.md: agent loop instructions
(inject script, poll loop, generate variants, accept/discard, cleanup)
CLI changes:
- bin/cli.js: added "poll" top-level command
- src/detect-antipatterns.mjs: liveCli() now delegates to src/live/server.mjs
- package.json: added ws dependency
Registered /impeccable live as command #22 across all standard locations.

Pre-3.0, onboard was folded into /harden when we were trying to reduce
namespace pollution. In the single-skill model that tradeoff is gone,
so the weakest of the old merges is the first to undo.
Harden and onboard live in different mental modes. Harden is defensive
(edge cases, i18n, overflow, errors). Onboard is activation (first-run
flows, empty states as CTAs, progressive disclosure). A user thinking
"design the onboarding flow" was never going to type /impeccable harden.
Changes:
- New reference file at source/skills/impeccable/reference/onboard.md,
restored from the pre-merge version in git history rather than the
condensed 33-line summary that was in harden.md.
- Removed the "Onboarding & First-Run Experience" section from
source/skills/impeccable/reference/harden.md.
- Updated harden description/editorial/process-steps to drop onboarding
keywords; split commandProcessSteps so harden stays focused on
production resilience and onboard gets its own phases.
- Registered onboard in: SKILL.md description + command menu + router
table, command-metadata.json, IMPECCABLE_SUB_COMMANDS, pin.mjs
VALID_COMMANDS, SKILL_CATEGORIES, COMMAND_RELATIONSHIPS, data.js
commandCategories + commandProcessSteps + commandRelationships,
framework-viz commandSymbols + commandNumbers.
- Reused the existing content/site/skills/onboard.md editorial wrapper
(it was orphaned by the merge but never deleted), updating it to use
/impeccable onboard.
- Bumped all user-facing count references 20 -> 21: public/index.html,
CLAUDE.md, README.md, NOTICE.md, plugin.json, marketplace.json,
sitemap.xml, build-sub-pages.js.
- Harness dir audit.md and critique.md changes are the
{{available_commands}} placeholder expanding to include onboard.

Biggest change in a while. Users previously had 18 standalone skill
entries cluttering their /menu; now they have one entry (/impeccable)
that routes to 20 specialized commands via argument dispatch. The pin
mechanism (/impeccable pin audit) restores standalone shortcuts on
demand for commands users hit all the time.
## Architecture
- Single /impeccable skill with command router section in SKILL.md
- 20 commands served via reference files under source/skills/impeccable/reference/
- /impeccable pin <command> creates a lightweight redirect shim so users
who prefer /audit, /polish, etc. can still have them
- Context gathering (teach) auto-runs on first use
- command-metadata.json is the single source of truth for command
descriptions, argument hints, and relationships
## Site rewrite
- Docs URL: /skills renamed to /docs (with /skills permanent redirects)
- Homepage hero frames Impeccable as "one skill with 20 commands"
- "Get Started" split into 50/50 install + how-to-use with editorial
numbered steps, /impeccable shown as the home command with three modes
- New /docs overview: home command hero card + dense category rows
matching the old cheatsheet density, with leads-to/pairs-with/
combines-with relationship metadata served from a shared source
- Cheatsheet merged into /docs, /cheatsheet redirects
- Magazine spread and mobile cards show /impeccable as a stacked
namespace label above the command name at full display size
- Periodic table updated with craft/teach/extract as first-class cells
- Skill detail pages generate from reference files, with an editorial
wrapper per command for tagline + body
- Tutorials and anti-patterns pages updated to use /impeccable <cmd>
## Build system
- Dead code removed (scripts/lib/transformers/shared.js)
- Build log wording fixed ("1 skill" not "1 skills (1 user-invocable)")
- generateApiData fallback branch removed (throws loudly if metadata
missing instead of silently degrading)
- Commands API includes editorial tagline alongside the long description;
UI surfaces prefer tagline for human display, description for auto-
trigger keyword matching
## Gitignore
- Added .claude/scheduled_tasks.lock, .claude/settings.local.json to
ignore list (local Claude Code state that should not be tracked).
- Harness skill directories (.claude/skills/, .agents/skills/, etc.)
remain tracked by design: npx skills reads them from this repo at
install time and they enable clean submodule use.

Three additions to the anti-patterns catalog page, all sourced from a
new content/site/anti-patterns-catalog.js file so the user's parallel
edits to src/detect-antipatterns.mjs don't conflict with display metadata.
1. Detection layer badge per rule. Three layers:
cli - static analysis or jsdom. Runs from `npx impeccable detect`
on files, no browser required. 23 of 25 current rules.
browser - needs real browser layout (getBoundingClientRect).
Runs via the browser extension or Puppeteer, not the
plain CLI. Only 2 rules: cramped-padding and line-length,
as documented in tests/detect-antipatterns-browser.test.mjs.
llm - no deterministic detector. Flagged by /critique's LLM
review pass. 13 rules live only in the skill's DON'T list.
Each card renders a mono pill with the layer label, color-coded per
layer (neutral mist for CLI, blue tint for browser, amber tint for LLM).
The How-to-read legend grows a dl explaining what each layer means.
2. Inline visual example per detected rule. All 25 detection rules get
a ~140px tall preview area at the top of the card showing the bad
pattern as live HTML (cream background, self-contained inline styles).
Visuals for side-tab, gradient-text, dark-glow, nested-cards, and the
rest let you see what the detector is actually flagging. LLM-only
rules ship without visuals for now; their card bodies take the full
card height.
3. LLM-only rules merged into the sections. Parsed out from
source/skills/impeccable/SKILL.md DON'T lines that the detector
doesn't cover: Syne, monospace-as-technical, dark-mode-default,
everything-in-cards, identical-card-grids, hero-metric-layout,
glassmorphism, sparkline-decoration, generic-drop-shadows,
modal-reflex, every-button-primary, redundant-headers,
mobile-amputation. Each renders like a detection rule card but
shows the 'LLM only' layer badge and has no rule id chip. They
slot into the same section groups as detected rules (Interaction
and Responsive sections added to the section order so these get
real headings).
- scripts/lib/sub-pages-data.js: imports the catalog, enriches
detected rules with { layer, visual }, appends LLM_ONLY_RULES with
layer: 'llm'. Re-exports LAYER_LABELS and LAYER_DESCRIPTIONS for
the generator.
- scripts/build-sub-pages.js: renderRuleCard adds the visual block
and the layer badge; LLM rules drop the rule id chip since their id
is just an internal slug. groupRulesBySection now extends the
primary order with whatever extra sections rules reference.
- public/css/sub-pages.css: .rule-card now has a .rule-card-visual
preview area on top with border-bottom, body section below. New
.rule-card-layer pill styling per layer. Layer legend dl using a
2-column grid for badge -> description.
Dev server serves 38 total cards (25 detected + 13 LLM) across 8
sections: Visual Details, Typography, Color & Contrast, Layout & Space,
Motion, Interaction, Responsive, General quality.
Feedback round from first review of the skill pages. Six concrete fixes:
1. Contain the auto-rendered SKILL.md in a distinct card.
The "skill itself" section was flowing straight into the editorial
wrapper above, making the two blocks read as one long mixed
document. Wrap the canonical body in .skill-source-card: white
paper background, mist border, rounded, with a small "SKILL.md"
badge header and an italic subtitle. Drop the old full-width
divider treatment; the card does the visual separation work.
2. Rewrite the /impeccable "do not fight the opinion" pitfall.
The old text said "fighting the opinion usually produces worse
output", which discouraged informed pushback. Replace with language
that explicitly encourages users with real reasons (brand guideline,
accessibility, user research) to push back; the skill raises the
floor, not overrules your judgment when you have evidence.
3. Move /onboard from create to refine.
Onboarding is refinement of empty states and first-run experiences,
not greenfield creation. Fixed in:
- scripts/lib/sub-pages-data.js SKILL_CATEGORIES
- public/js/data.js commandCategories
Both locations now list onboard under 'refine'.
4. De-dupe overdrive and animate.
- overdrive: "how it works" listed 7 techniques as bullets and then
"try it" listed 5 concrete examples using the same 7 techniques.
Collapse "how it works" into a tight paragraph and make "try it"
a specific scenario instead of a laundry list.
- animate: pitfalls repeated the "no layout properties" rule that
was already stated in "how it works". Drop the duplicate.
5. Remove outdated tutorial guidance.
getting-started.md said "Cursor needs Nightly channel plus Agent
Skills in Settings. Gemini CLI needs the preview version." Neither
is true anymore. Replace with a generic pointer to check the
harness's own skill docs.
6. Embed the live visual overlay in critique-with-overlay tutorial.
The tutorial now renders the same demo iframe the homepage uses
(/antipattern-examples/visual-mode-demo.html) inside step 2, with
a mac-window chrome frame that mirrors the homepage preview. New
.tutorial-embed CSS in sub-pages.css defines the header with
traffic-light dots + mono title, the iframe body (520px tall),
and an optional caption. The user now sees the overlay in action
before being asked to run it locally.

New skill that pushes interfaces past conventional limits with
bleeding-edge browser APIs: WebGPU shaders, scroll-driven animations,
View Transitions, generative art, spring physics, and more.
Key design decisions:
- Strong "when to use / when not to" guardrails

- "Pick ONE hero moment" philosophy — restraint in choosing where
- The extraordinary/gimmicky line defined explicitly
- prefers-reduced-motion respect required
Also updates all counts to 20 commands across website, docs, and
plugin metadata.
