## What it does

design-qa helps build a UI QA workflow covering token and hardcoded-value linting, automated accessibility checks with axe-core or Pa11y, contrast, and visual snapshots. The checks can cover component states, light and dark themes, RTL, and key breakpoints. A manual accessibility checklist is included for release sign-off.

The skill relies on files from the kit. Its checks include Python scripts for tokens, contrast, and hardcoded values, plus `gate.mjs`, which opens a page in headless Chromium and measures contrast on rendered text. Installing only the skill folder is not enough: if the `tokens` directory is missing, stop and install the kit with `npx ux-ui-agent-skills init` or install the plugin. Without the kit files, the checks cannot read the required data.

## Requirements
- Works with: Chrome

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add plugin87/ux-ui-agent-skills --skill design-qa -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add plugin87/ux-ui-agent-skills --skill design-qa -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add plugin87/ux-ui-agent-skills --skill design-qa -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install plugin87/ux-ui-agent-skills design-qa
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add plugin87/ux-ui-agent-skills --skill design-qa -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/plugin87/ux-ui-agent-skills --path .claude/skills/design-qa
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add plugin87/ux-ui-agent-skills --skill design-qa -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/plugin87/ux-ui-agent-skills/tree/HEAD/.claude/skills/design-qa/SKILL.md

## When to use it
- lint tokens and hardcoded values in component code
- detect contrast failures in rendered UI
- check component states with axe-core or Pa11y
- compare visual snapshots across themes, variants, and RTL
- complete a manual accessibility review before release

## Example prompts
- Set up design checks for this project and add the fast gates to CI.
- Check every state of this component with axe-core or Pa11y.
- Capture visual snapshots of the components in dark mode and RTL.

# Skill: Design QA

> **Step 0: is the kit here?** This skill reads files from the kit. Check once:
> `ls ${CLAUDE_SKILL_DIR}/../../../tokens >/dev/null 2>&1 && echo KIT_OK || echo KIT_MISSING`
> On `KIT_MISSING` only the skill folders were installed, which is what
> `npx skills add` does. Say so plainly, point the user at

Stand up the automated + manual gates that stop quality from regressing.

## Steps
1. Read `${CLAUDE_SKILL_DIR}/../../../workflows/design-qa.md` (the QA pyramid: token/lint gates → automated a11y → visual regression → manual a11y).
2. Wire the **fast gates** first (every commit/PR): `python3 ${CLAUDE_SKILL_DIR}/../../../scripts/validate_tokens.py`, `python3 ${CLAUDE_SKILL_DIR}/../../../scripts/validate_contrast.py` (batch WCAG over the token pairs), and `python3 ${CLAUDE_SKILL_DIR}/../../../scripts/lint_hardcodes.py <src>` (no raw hex/px/timing in component code). The repo's `.github/workflows/ci.yml` runs these.
3. Add **automated a11y** (axe-core / Pa11y) over each component's states (error/loading/disabled/expanded/selected), zero serious/critical to merge. Run the **real-render contrast gate** `node ${CLAUDE_SKILL_DIR}/../../../scripts/gate.mjs measure_render.mjs <file.html>` (and `--dark`). It opens the page in headless Chromium, disables transitions, and measures the true computed-style + alpha-composited contrast of every text element (catches what static token checks miss).
4. Add **visual regression** snapshots across variants × sizes × states × light/dark + key breakpoints + RTL; freeze animations + deterministic data.
5. Sign off the **manual a11y** checklist per release (keyboard, screen reader, 400% reflow, 200% text-spacing, reduced-motion, forced-colors; `${CLAUDE_SKILL_DIR}/../../../accessibility/*`).

## Verification (definition of done)
- An unreviewed PR cannot introduce an unresolved token alias, a contrast failure, a raw hex/px, or an axe violation: a gate blocks each.
- Snapshots cover dark mode + RTL + the semantic-changing states, not just the happy path.
- Manual a11y checklist signed off for the release.
