## What it does

The skill reviews code for semantic HTML, keyboard access, color contrast, accessible forms, ARIA, and motion behavior. It also covers images, heading structure, and layout stability. Use it when reviewing an existing interface or building components.

It scopes an audit to supplied files, or checks the project’s UI pages and components when no files are given. File extensions help it identify React, Vue, Laravel Blade, or static HTML. Each checklist item gets a result: a confirmation, an issue with `file:line` and a suggested fix, or a note that the check does not apply. The final report includes a WCAG level and priority fixes.

The rules cover WCAG AA, forms, and animation; the skill can also serve as a coding reference. Findings depend on the project code, so precise locations require the relevant interface files.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add AsyrafHussin/agent-skills --skill web-design-guidelines -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add AsyrafHussin/agent-skills --skill web-design-guidelines -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add AsyrafHussin/agent-skills --skill web-design-guidelines -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install AsyrafHussin/agent-skills web-design-guidelines
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add AsyrafHussin/agent-skills --skill web-design-guidelines -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/AsyrafHussin/agent-skills --path skills/web-design-guidelines
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add AsyrafHussin/agent-skills --skill web-design-guidelines -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/AsyrafHussin/agent-skills/tree/HEAD/skills/web-design-guidelines/SKILL.md

## When to use it
- audit pages against WCAG guidance
- find controls that keyboard users cannot reach
- check form labels and accessible error messages
- review text contrast and visible focus states
- spot ARIA and motion issues

## Example prompts
- Audit accessibility in `src/pages/Home.tsx` and `src/components/Form.tsx`.
- Review the project’s forms and find fields missing labels or accessible error messages.
- Check the interface for keyboard access, contrast, and support for `prefers-reduced-motion`.

# Web Design Guidelines

WCAG accessibility, semantic HTML, keyboard navigation, forms, and performance patterns for inclusive web interfaces. Contains 23 rules across 4 categories. Supports both **coding reference** and **audit mode**.

## Metadata

- **Version:** 2.1.0
- **Rule Count:** 23 rules across 4 categories

## How to Audit

When the user asks to "audit accessibility", "check WCAG compliance", or "review accessibility" — run the checklist below against their codebase.

### Step 1: Determine Scope

- If arguments provided (`$ARGUMENTS`): audit only those files or components
- If no arguments: audit all UI components and pages in the codebase

### Step 2: Detect Stack

Check the project for:
- `.tsx`/`.jsx` files → React
- `.vue` files → Vue
- `.blade.php` files → Laravel Blade
- `.html` files → Static HTML

### Step 3: Run Accessibility Checklist

Work through every item below. For each, output:
- **PASS** — brief confirmation of what was verified
- **FAIL** — exact `file:line`, description of the issue, and fix recommendation
- **N/A** — if the check does not apply to this project

#### Semantic HTML & Structure
- [ ] Pages use semantic elements (`<header>`, `<main>`, `<nav>`, `<footer>`, `<article>`, `<section>`) — not `<div>` soup
- [ ] Heading hierarchy is sequential (`h1` → `h2` → `h3`) — no skipped levels
- [ ] One `<h1>` per page
- [ ] Skip link exists to bypass navigation (`<a href="#main-content">Skip to content</a>`)
- [ ] Landmark regions are labelled when duplicated (`aria-label` on multiple `<nav>` elements)

#### Keyboard Navigation
- [ ] All interactive elements are reachable via Tab key
- [ ] Focus order follows visual order (no positive `tabindex` values)
- [ ] Focus indicator is visible on all focusable elements (not removed with `outline: none` without replacement)
- [ ] Modal dialogs trap focus and return focus on close
- [ ] Custom components (dropdowns, tabs, accordions) support expected keyboard patterns (Arrow keys, Escape, Enter)

#### Images & Media
- [ ] All `<img>` elements have `alt` attributes — descriptive for content images, empty (`alt=""`) for decorative
- [ ] Complex images (charts, diagrams) have extended descriptions
- [ ] Video content has captions or transcripts

#### Color & Contrast
```
