## What it does

The command reviews UI code against WCAG 2.1 criteria. It checks text alternatives, semantic structure, keyboard access, focus behavior, forms, dynamic content, ARIA usage, and common markup patterns such as clickable `div` elements or missing `alt` attributes.

Before the review, it creates `.ui-design/audits/`, reads project context from `conductor/tech-stack.md` and `.ui-design/design-system.json`, and writes the result to `.ui-design/audits/{audit_id}.md`. Available CSS or design tokens can be used for contrast checks. When no level is supplied, the audit uses WCAG 2.1 AA, so an AAA review requires `--level AAA`.

## Install

### Claude Code (native platform)

1. **Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add wshobson/agents
```
In the agent chat (not a shell):
```text
/plugin install ui-design@claude-code-workflows
```

2. **Manually: put the files in place**
- File: `.claude/commands/accessibility-audit.md` — Call it with /accessibility-audit. For all projects use ~/.claude/commands/

### Codex

**Manually: put the files in place**
- File: `~/.codex/prompts/accessibility-audit.md` — Call it with /prompts:accessibility-audit. Codex marks this format deprecated in favour of skills

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/prompts/accessibility-audit.prompt.md`

### Gemini CLI

**Manually: put the files in place**
- File: `.gemini/commands/accessibility-audit.toml` — Gemini stores commands as TOML: the prompt text goes into the prompt field

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/wshobson/agents/tree/HEAD/plugins/ui-design/commands/accessibility-audit.md

## When to use it
- audit a component against WCAG criteria
- spot keyboard and focus-access issues
- find invalid or redundant ARIA usage
- check text and background contrast
- write findings to a Markdown report

## Example prompts
- Run `/accessibility-audit` across the application at level AA.
- Audit `src/components/Button.tsx` with `/accessibility-audit src/components/Button.tsx --level AAA`.
- Review `CheckoutForm` for keyboard access and ARIA problems.

# Accessibility Audit

Comprehensive audit of UI code for WCAG 2.1/2.2 compliance. Identifies accessibility issues and provides actionable remediation guidance.

## Pre-flight Checks

1. Check if `.ui-design/` directory exists:
   - If not: Create `.ui-design/` directory
   - Create `.ui-design/audits/` subdirectory for audit results

2. Load project context:
   - Check for `conductor/tech-stack.md` for framework info
   - Check for `.ui-design/design-system.json` for color tokens
   - Detect testing framework for a11y test suggestions

## Target and Level Configuration

### If argument provided:

- Parse for file path or component name
- Parse for `--level` flag (AA or AAA)
- Default to WCAG 2.1 Level AA if not specified

### If no argument:

**Q1: Audit Target**

```
What would you like to audit?

1. A specific component (provide name or path)
2. A page/route (provide path)
3. All components in a directory
4. The entire application
5. Recent changes only (last commit)

Enter number or provide a file path:
```

**Q2: Compliance Level**

```
What WCAG compliance level should I audit against?

1. Level A   - Minimum accessibility (must-fix issues)
2. Level AA  - Standard compliance (recommended, most common target)
3. Level AAA - Enhanced accessibility (highest standard)

Note: Each level includes all requirements from previous levels.

Enter number:
```

**Q3: Focus Areas (optional)**

```
Any specific areas to focus on? (Press enter to audit all)

1. Color contrast and visual presentation
2. Keyboard navigation and focus management
3. Screen reader compatibility
4. Forms and input validation
5. Dynamic content and ARIA
6. All areas

Enter numbers (comma-separated) or press enter:
```

## State Management

Create `.ui-design/audits/audit_state.json`:

```json
{
  "audit_id": "{target}_{YYYYMMDD_HHMMSS}",
  "target": "{file_path_or_scope}",
  "wcag_level": "AA",
  "focus_areas": ["all"],
  "status": "in_progress",
  "started_at": "ISO_TIMESTAMP",
  "files_audited": 0,
  "issues_found": {
    "critical": 0,
    "serious": 0,
    "moderate": 0,
    "minor": 0
  },
  "criteria_checked": 0,
  "criteria_passed": 0
}
```

## Audit Execution

### 1. File Discovery

Identify all files to audit:

- If single file: Audit that file
- If component: Find all related files (component, styles, tests)
- If directory: Recursively find UI files (`.tsx`, `.vue`, `.svelte`, etc.)
- If application: Audit all component and page files

### 2. Static Code Analysis

For each file, check against WCAG criteria:

#### Perceivable (WCAG 1.x)

**1.1 Text Alternatives:**

- [ ] Images have `alt` attributes
- [ ] Decorative images use `alt=""` or `role="presentation"`
- [ ] Complex images have extended descriptions
- [ ] Icon buttons have accessible names

**1.2 Time-based Media:**

- [ ] Videos have captions
- [ ] Audio has transcripts
- [ ] Media players are keyboard accessible

**1.3 Adaptable:**

- [ ] Semantic HTML structure (headings, lists, landmarks)
- [ ] Proper heading hierarchy (h1 > h2 > h3)
- [ ] Form inputs have associated labels
- [ ] Tables have proper headers
- [ ] Reading order is logical

**1.4 Distinguishable:**

- [ ] Color contrast meets requirements (4.5:1 normal, 3:1 large)
- [ ] Color is not sole means of conveying information
- [ ] Text can be resized to 200%
- [ ] Focus indicators are visible
- [ ] Content reflows at 320px width (AA)

#### Operable (WCAG 2.x)

**2.1 Keyboard Accessible:**

- [ ] All interactive elements are keyboard accessible
- [ ] No keyboard traps
- [ ] Focus order is logical
- [ ] Custom widgets follow ARIA patterns

**2.2 Enough Time:**

- [ ] Time limits can be extended/disabled
- [ ] Auto-updating content can be paused
- [ ] No content times out unexpectedly

**2.3 Seizures:**

- [ ] No content flashes more than 3 times/second
