## What it does

This skill reviews an interface along three lines: accessibility, performance and responsiveness. It starts by capturing the surface as a user sees it — first through the `playwright` MCP server, then DevTools or another browser automation tool. When none of those is around, it asks you for screenshots at 1280×800, 768×1024 and 375×812, plus dark mode where the app has one. Decline, and the report gets stamped `[CODE-ONLY REVIEW — visual issues not assessed]`; some problems will slip through.

The checks are fixed, not configurable. Every interactive element needs a visible `:focus-visible`, keyboard reach with no focus traps, touch targets of at least 44px on mobile, form labels tied to their errors, and `prefers-reduced-motion` respected. Performance looks at whether only `transform` and `opacity` are animated, whether `transition: all` crept in, whether images carry `width`/`height` or `aspect-ratio`. Responsive work covers mobile-first breakpoints, `env(safe-area-inset-*)` on fixed elements, and no horizontal scroll at 320px.

Findings land in a Before / After / Why table, sorted into Critical, High-impact and Quick wins. The skill won't touch your code until you approve — report first, edits after. It closes with a Craft Report naming the checked scope and the top priority.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add educlopez/ui-craft --skill audit -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/audit/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/audit/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add educlopez/ui-craft --skill audit -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/audit/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add educlopez/ui-craft --skill audit -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/audit/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install educlopez/ui-craft audit
```

2. **Manually: put the files in place**
- File: `.github/skills/audit/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add educlopez/ui-craft --skill audit -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/educlopez/ui-craft --path cli/assets/codex/skills/audit
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/audit/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add educlopez/ui-craft --skill audit -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/educlopez/ui-craft/tree/HEAD/cli/assets/codex/skills/audit/SKILL.md

## When to use it
- spot interactive elements with no visible focus ring
- check whether the layout breaks at 320px
- catch animations that trigger repaints
- collect accessibility issues into one prioritized report
- verify touch target sizes on mobile

## Example prompts
- Audit the UI on the `checkout` page
- Run a technical audit of accessibility and performance on the landing page
- Audit responsiveness: check 320px and mobile touch zones

**Context:** this sub-skill is one lens of the broader `ui-craft` skill. If the `ui-craft` skill is also installed, read its SKILL.md first for Discovery + Anti-Slop + Craft Test, then apply the specific lens below.

Run a technical audit of the UI at `$ARGUMENTS`. Load the `ui-craft` skill and apply the audit lens.

## Step 0: Visual capture (mandatory)

Code-only review is insufficient. Every audit/critique starts with the surface as the user sees it. Try the following in order; use the first one available:

1. **Playwright MCP** — if `playwright` MCP server is available, use it. Capture full-page screenshots at three viewports: desktop (1280×800), tablet (768×1024), mobile (375×812). Capture dark mode if the app supports it.
2. **Browser DevTools / Chrome MCP** — second choice; same viewport set.
3. **Other browser automation** (`agent-browser`, `cursor-ide-browser`) — third choice.
4. **Ask the user** — last resort. If no automation is available, request screenshots from the user before proceeding. Be specific:
   - "Visual review needs screenshots. Please provide:
     - Full-page at 1280px (desktop)
     - Full-page at 768px (tablet)
     - Full-page at 375px (mobile)
     - Dark mode of each, if supported."

Do not begin the review until visuals are captured or provided. State this explicitly to the user when no automation succeeds — don't silently fall back to code-only review.

If the user declines to provide screenshots, run a code-only pass and clearly mark the report `[CODE-ONLY REVIEW — visual issues not assessed]` at the top so the limitation is explicit.

**Note:** audit is knob-agnostic — accessibility and performance are not tunable.

**Scope (non-negotiable checks):**

1. **Accessibility** — read `references/accessibility.md`:
   - Visible `:focus-visible` on every interactive element
   - Keyboard reachable, no focus traps
   - Touch targets ≥ 44px (mobile)
   - Color not the only signal for state
   - Form labels, error association, required indication
   - `prefers-reduced-motion` honored for all animations
2. **Performance** — read `references/motion.md` Rendering Performance section:
   - Only `transform` / `opacity` animated (no `width`/`top`/`height`)
```
