Paul BakausandClaude Opus 4.6 af2d6e1194 Support PRODUCT.md + DESIGN.md as canonical context files
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).

<li><strong>18 skills became 1 skill with 23 commands.</strong> Every command now lives under <code>/impeccable</code>: <code>/impeccable audit</code>, <code>/impeccable polish</code>, <code>/impeccable critique</code>, and the rest. One entry in your <code>/</code> menu instead of 18, a shared design vocabulary between you and your AI, and far less namespace pollution as the plugin ecosystem grows. The autocomplete shows the full list the moment you type <code>/impeccable</code>.</li>
<li><strong>Pin your favorites back as shortcuts.</strong> Run <code>/impeccable pin audit</code> and <code>/audit</code> becomes a standalone command again, without reversing the consolidation. Under the hood it writes a lightweight redirect skill that delegates to <code>/impeccable audit</code>, so updates to the parent skill flow through automatically. <code>/impeccable unpin audit</code> removes it.</li>

<ul class="changelog-items">
<li><strong>Streamlined from 21 to 18 commands.</strong> Removed overlap and confusion: <code>/arrange</code> renamed to <code>/layout</code>, <code>/normalize</code> merged into <code>/polish</code> (design system alignment is now part of the final pass), <code>/onboard</code> merged into <code>/harden</code> (empty states and first-run experiences are part of production readiness), and <code>/extract</code> became <code>/impeccable extract</code> (a sub-mode alongside craft and teach). Every remaining command has a clearly distinct job.</li>
<li><strong>Automatic cleanup of deprecated skills.</strong> On first load after updating, the skill detects and removes leftover files from renamed or merged commands. No manual cleanup needed.</li>

<span class="changelog-version">v2.0</span>
<span class="changelog-date">April 8, 2026</span>
</div>
<ul class="changelog-items">
<li><strong>Renamed <code>frontend-design</code> to <code>impeccable</code>.</strong> The core skill now shares its name with the project, and the teach subcommand moved from <code>/teach-impeccable</code> to <code>/impeccable teach</code>. One skill, one namespace.</li>
<li><strong>Data-driven skill rewrite.</strong> The core skill was rebuilt against an internal eval framework that runs the same brief through frontier models with and without the skill loaded, then measures how much the output collapses into monoculture. The result: dramatically more font and color diversity, sharper overall design quality, and much stronger Codex support. The biggest unlock was an anti-attractor procedure that forces the model to enumerate and reject its reflex defaults before picking. Validated on gpt-5.4 and Qwen 3.6 Plus across 15 niches.</li>
<li><strong>Anti-pattern detection engine.</strong> 25 deterministic rules across typography, color, layout, motion, and quality. Handles oklch, oklab, lch, and lab color formats, CSS variables inside border shorthands, gradient-backed text, and emoji-only nodes.</li>
<li><strong>CLI: <code>npx impeccable detect</code>.</strong> Scans HTML, CSS, JSX/TSX, Vue, Svelte, and CSS-in-JS. Framework detection, multi-file import tracking, Puppeteer-backed live URL scanning, CI-ready JSON output, and a <code>--fast</code> regex mode for huge codebases.</li>
<li><strong>Chrome DevTools extension.</strong> One-click detection on any page: yours, staging, production, or someone else's. Reads live computed styles, surfaces findings in an interactive panel, and highlights elements on the page. In Chrome Web Store review.</li>
<li><strong><code>/critique</code> got teeth.</strong> Persona sub-agents review in parallel, score against Nielsen's heuristics, run the detector automatically, and open a live browser overlay so you can walk each finding in place.</li>
<li><strong>New ways to create with Impeccable.</strong> <code>/shape</code> runs a structured discovery interview about purpose, audience, and goals, then produces a design brief before any code is written. <code>/impeccable craft</code> chains that brief straight into the full implementation flow so you ship a designed feature instead of a reflex card grid.</li>
<li><strong>New docs site.</strong> Top-level <a href="/docs">Docs</a>, <a href="/anti-patterns">Anti-Patterns</a>, and <a href="/visual-mode">Visual Mode</a> sections. 18 per-skill pages with before/after demos and the canonical SKILL.md inline, two <a href="/tutorials">tutorials</a>, and 38 rule cards with inline visual examples.</li>

</div>
<div class="faq-list" data-reveal>
<details class="faq-item">
<summary class="faq-question">Where do I put the downloaded files?</summary>
<div class="faq-answer">
<p>The easiest way is <code>npx skills add pbakaus/impeccable</code>, which auto-detects your AI harness and places files correctly.</p>
<p>If you downloaded the <strong>universal ZIP</strong>, extract it to your <strong>project root</strong> (same level as your <code>package.json</code> or <code>src/</code> folder). It creates hidden folders for each supported tool: <code>.cursor/</code>, <code>.claude/</code>, <code>.gemini/</code>, <code>.codex/</code>, <code>.agents/</code>, and <code>.github/</code>.</p>
<p>Project-level installation takes precedence and lets you version control your skills.</p>
</div>
</details>
<details class="faq-item">
<summary class="faq-question">How do I update to the latest version?</summary>
<div class="faq-answer">
<p>Run <code>npx impeccable skills update</code> from your project root. It downloads the latest skills, cleans up deprecated files, and preserves any prefix you use.</p>
<ul>
<li><strong>Alternative:</strong> <code>npx skills add pbakaus/impeccable</code> re-installs from scratch.</li>
<li><strong>Claude Code plugin:</strong> Open <code>/plugin</code>, go to the Discover tab.</li>
<li><strong>Manual ZIP:</strong> Download from above and extract to the project root.</li>
</ul>
<p>Your <code>.impeccable.md</code> context file is never overwritten.</p>
</div>
</details>
<details class="faq-item">
<summary class="faq-question">Commands or skills aren't appearing. What do I do?</summary>
<div class="faq-answer">
<p><strong>For commands:</strong> Type <code>/impeccable</code> in your AI harness and look for commands like <code>/impeccable audit</code>, <code>/impeccable polish</code>, etc. If they don't appear, double-check the files are in the correct location.</p>
<p><strong>For skills:</strong> Skills are applied automatically when relevant. To verify, explicitly mention "use the impeccable skill" in your prompt. This forces the AI to acknowledge and apply it.</p>
<p><strong>Tool-specific setup:</strong></p>
<ul>
<li><strong>Cursor:</strong> Requires Nightly channel + Agent Skills enabled in Settings → Rules</li>
<li><strong>Gemini CLI:</strong> Requires <code>@google/gemini-cli@preview</code> + Skills enabled via <code>/settings</code></li>
<li><strong>Codex:</strong> Skills do not appear in the normal <code>/</code> command picker. Open <code>/skills</code> or type <code>$</code>. Repo installs live in <code>.agents/skills/</code>, user installs live in <code>~/.agents/skills/</code>. Restart Codex if a new skill does not show up.</li>
</ul>
</div>
</details>
<details class="faq-item">
<summary class="faq-question">I'm new to AI harnesses. Where do I start?</summary>
<div class="faq-answer">
<p>Skills and commands are intermediate features. If you're just getting started, learn the basics first:</p>
<ul>
<li><strong>Claude Code:</strong> <a href="https://docs.anthropic.com/en/docs/claude-code" target="_blank" rel="noopener">Official Documentation</a></li>
<li><strong>Cursor:</strong> <a href="https://docs.cursor.com" target="_blank" rel="noopener">Cursor Docs</a></li>
<li><strong>Gemini CLI:</strong> <a href="https://geminicli.com/docs/" target="_blank" rel="noopener">Gemini CLI Docs</a></li>
<li><strong>Codex CLI:</strong> <a href="https://github.com/openai/codex" target="_blank" rel="noopener">Codex GitHub</a></li>
</ul>
<p>Once you're comfortable with basic prompting and code generation, come back and give Impeccable a try.</p>
</div>
</details>
<details class="faq-item">
<summary class="faq-question">Is Impeccable free?</summary>
<div class="faq-answer">
<p>Yes. Everything is <strong>Apache 2.0</strong>: skills, commands, CLI, and the detection engine. Fully open source, free for everyone.</p>
