Accessibility Audit Skill
Comprehensive WCAG 2.2 Level AA accessibility auditing for React/TypeScript applications with MUI framework awareness.
Quick Reference
| Severity | Impact | Examples |
|---|---|---|
| Critical | Blocks access completely | Keyboard traps, missing alt on actions, no focus visible |
| High | Significantly degrades UX | Poor contrast on CTAs, no skip navigation, small touch targets |
| Medium | Minor usability impact | Missing autocomplete, unclear link text |
| Low | Best practice enhancement | Could add tooltips, more descriptive titles |
Key Principle
Severity = Impact x Likelihood, NOT WCAG conformance level. A Level A failure can be LOW severity; a Level AA failure can be CRITICAL.
Required Tooling
# Install required tools
npm install --save-dev eslint-plugin-jsx-a11y jest-axe @axe-core/playwright
# Configure ESLint
# Add to .eslintrc: extends: ['plugin:jsx-a11y/recommended']
Workflow
| Phase | Description |
|---|---|
| 1. Setup | Install tooling, create output directories |
| 2. Static Analysis | ESLint jsx-a11y scan |
| 3. Runtime Analysis | jest-axe and Playwright |
| 4. Manual Validation | Keyboard, screen reader, contrast |
| 5. Report Generation | JSON + Markdown outputs |
Phase 1: Setup
See workflow/setup.md for installation and configuration.
Phase 4: Manual Validation
See workflow/manual-validation.md for keyboard and screen reader testing.
