## What it does

The skill runs an accessibility-only review. It looks at semantic markup, focus order, keyboard navigation, contrast and screen-reader labels, then writes `a11y-review.md` with findings tied to WCAG criteria. Only code that clearly violates a cited Success Criterion counts as a problem — general style and anything unrelated to accessibility is left alone.

Reference files inside the skill cover individual criteria, grouped by principle such as Perceivable, and the skill opens the ones relevant to the code under review. You need `python3` 3.8 or newer. Several rules cut false positives: Lightning base components (`lightning-input`, `lightning-combobox`, `lightning-textarea`, `lightning-icon`) and imported controls from React, Vue or Angular are treated as accessible out of the box when given a labeling prop like `label` or `aria-label`. Dynamic `id` and `htmlFor` pairs bound to the same expression are not flagged either.

This skill does not generate LWC — that is `experience-lwc-generate`. Visual SLDS review without an accessibility focus belongs to `design-systems-slds-validate`. If what you want is an accessibility review, this is the one to install.

## Requirements
- Works with: Salesforce

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill experience-accessibility-validate -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill experience-accessibility-validate -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill experience-accessibility-validate -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install forcedotcom/sf-skills experience-accessibility-validate
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill experience-accessibility-validate -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/forcedotcom/sf-skills --path skills/experience-accessibility-validate
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill experience-accessibility-validate -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/forcedotcom/sf-skills/tree/HEAD/skills/experience-accessibility-validate/SKILL.md

## When to use it
- check an LWC against WCAG 2.2
- find accessibility problems in component markup
- confirm a component works with a screen reader
- verify keyboard navigation and focus order
- audit ARIA attribute usage in a template

## Example prompts
- check this LWC for WCAG 2.2 accessibility issues
- find accessibility problems in my component
- is this component keyboard accessible?

# Web Component Accessibility

Accessibility (a11y) patterns and remediation guidance for web components.
Reference any time work involves the visible or interactive surface of a
component — generating, modifying, reviewing, or styling HTML, JS, or
CSS — to apply WCAG 2.2 standards.

## Review Context

Conduct a review specifically focused on enhancing web accessibility, guided by the WCAG (Web Content Accessibility Guidelines).

In order to mark code as a violation, it must have a direct correlation to the WCAG rule cited such that it is a clear violation of the criteria.

Key Review Criteria:

1. Focus Exclusively on Accessibility:

- Evaluate the component solely for accessibility.
- Only consider compliance with the cited WCAG Success Criteria, ignoring violations that can be attributed to other criteria.
- Avoid addressing general code style, patterns, or issues unrelated to accessibility.

2. Ensure Minimum and Sufficient Accessibility:

- Identify accessibility issues that prevent the component from meeting the minimum requirements outlined by WCAG.
