## What it does

The skill structures an accessibility audit against WCAG 2.1 Level A and AA standards. The workflow starts with automated CLI scans and assertions using `jest-axe` or `Playwright`. After that, you inspect keyboard tab order and screen reader behavior in NVDA or VoiceOver.

Reference documents provide fixes for the seven most frequent defects, a `sr-only` class, and ARIA markup for interactive components like tabs or accordions. Automated tooling alone never catches every problem: CLI scanners detect invalid syntax, but focus traps and announcement clarity demand manual verification.

After fixing identified issues, the workflow requires rerunning step-one automated scans until zero defects remain.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add OneWave-AI/claude-skills --skill accessibility-auditor -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add OneWave-AI/claude-skills --skill accessibility-auditor -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add OneWave-AI/claude-skills --skill accessibility-auditor -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install OneWave-AI/claude-skills accessibility-auditor
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add OneWave-AI/claude-skills --skill accessibility-auditor -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/OneWave-AI/claude-skills --path accessibility-auditor
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add OneWave-AI/claude-skills --skill accessibility-auditor -a opencode
```

## When to use it
- Configure accessibility assertions with `jest-axe` and `Playwright`
- Audit web pages against WCAG 2.1 Level A and AA criteria
- Detect keyboard focus traps and improper tab order
- Add ARIA markup for tabs, accordions, and menus
- Resolve frequent accessibility defects using the `sr-only` utility class

## Example prompts
- Audit this page for accessibility defects against WCAG 2.1 AA
- Add jest-axe and Playwright assertions to test this form for a11y
- Fix the tab order and ARIA attributes in our accordion component

# Accessibility Auditor

Audit a website for accessibility defects and bring it to WCAG 2.1 AA compliance.

## Contents

- `references/automated-testing.md` - CLI commands, jest-axe, Playwright, and tooling
- `references/wcag-checklist.md` - WCAG Level A/AA criteria and keyboard testing checklist
- `references/common-fixes.md` - Fix patterns for the 7 most common defects plus the sr-only class
- `references/aria-patterns.md` - ARIA markup for tabs, accordion, menu, alert, progress

## Workflow

1. Run automated checks. Execute the CLI scans and add jest-axe or Playwright assertions per `references/automated-testing.md`.
2. Test the keyboard. Tab through the page and verify order, activation, escape, focus visibility, and absence of traps using the checklist in `references/wcag-checklist.md`.
3. Test with a screen reader. Walk the page with NVDA or VoiceOver and confirm names, roles, and announced state.
4. Check WCAG criteria. Audit each Level A and AA criterion in `references/wcag-checklist.md`.
5. Apply fixes. Resolve each finding with the patterns in `references/common-fixes.md` and `references/aria-patterns.md`, then re-run step 1 to confirm zero violations.
