## What it does

The skill instructs the coding agent to apply WCAG accessibility criteria to web components. Instead of generic `div` structures, the agent selects semantic HTML tags like `nav`, `main`, or `article`. It also attaches appropriate ARIA roles so screen readers interpret the interface accurately.

Five standalone documents live in the `references/` directory. They cover semantic HTML with ARIA, keyboard navigation routines, visual contrast, screen reader announcements, and testing procedures. Each guide enforces clean, well-documented code.

The rules explicitly prohibit skipping validation and ignoring error handling. You cannot hard-code configuration values either. Because of these constraints, the assistant must verify accessibility before marking a task complete.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill frontend-accessibility -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill frontend-accessibility -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill frontend-accessibility -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aj-geddes/useful-ai-prompts frontend-accessibility
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill frontend-accessibility -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aj-geddes/useful-ai-prompts --path skills/frontend-accessibility
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aj-geddes/useful-ai-prompts --skill frontend-accessibility -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/aj-geddes/useful-ai-prompts/tree/HEAD/skills/frontend-accessibility/SKILL.md

## When to use it
- structure interfaces with semantic HTML and ARIA attributes
- implement keyboard navigation and focus management
- fix color contrast and visual accessibility issues
- configure live announcements for screen readers
- test frontend components against WCAG requirements

## Example prompts
- Review this navigation bar for WCAG compliance and add ARIA attributes
- Enable keyboard navigation and focus trapping for the dialog modal
- Adjust color contrast for buttons and add hidden screen reader text

## Overview

Build accessible web applications following WCAG guidelines with semantic HTML, ARIA attributes, keyboard navigation, and screen reader support for inclusive user experiences.

## When to Use

- Compliance with accessibility standards
- Inclusive design requirements
- Screen reader support
- Keyboard navigation
- Color contrast issues

## Quick Start

Minimal working example:

```html
<!-- Good semantic structure -->
<nav aria-label="Main navigation">
  <ul>
    <li><a href="/">Home</a></li>
    <li><a href="/about">About</a></li>
    <li><a href="/contact">Contact</a></li>
  </ul>
</nav>

<main>
  <article>
    <header>
      <h1>Article Title</h1>
      <time datetime="2024-01-15">January 15, 2024</time>
    </header>
    <p>Article content...</p>
  </article>

  <aside aria-label="Related articles">
    <h2>Related Articles</h2>
    <ul>
      <li><a href="/article1">Article 1</a></li>
      <li><a href="/article2">Article 2</a></li>
    </ul>
  </aside>
// ... (see reference guides for full implementation)
```

## Reference Guides

| [Screen Reader Announcements](references/screen-reader-announcements.md) | Screen Reader Announcements |
| [Accessibility Testing](references/accessibility-testing.md) | Accessibility Testing |

## Best Practices

### ✅ DO

- Follow established patterns and conventions
- Write clean, maintainable code
- Add appropriate documentation
- Test thoroughly before deploying

### ❌ DON'T

- Skip testing or validation
- Ignore error handling
- Hard-code configuration values
