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
npm install --save-dev eslint-plugin-jsx-a11y jest-axe @axe-core/playwright
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.
Reference
Common False Positives to Avoid
| Component | Built-in Behavior | Don't Flag |
|---|
MUI <SvgIcon> | Auto aria-hidden="true" | Icons without titleAccess |
MUI <Alert> | Default role="alert" | Missing role attribute |
MUI <Button> | 36.5px min height | Target size < 44px |
MUI <TextField> | Auto label association | Missing label |
MUI <Autocomplete> | Manages ARIA attrs | Missing aria-expanded |
