Audit: $ARGUMENTS
AccessibilityAudit {
Checklist {
1. Semantic HTML — Are headings in order (h1 > h2 > h3)? Are lists, tables, and landmarks used correctly? Are <button> and <a> used for their intended purposes?
2. Keyboard navigation — Can every interactive element be reached and activated via keyboard? Is focus order logical? Are focus traps handled for modals/dialogs?
3. ARIA — Are aria-label, aria-describedby, aria-live, and roles used correctly? Is ARIA only added when native HTML semantics are insufficient?
4. Color & contrast — Do text/background combinations meet 4.5:1 (normal text) or 3:1 (large text) contrast ratios? Is color never the only way to convey information?
5. Forms — Does every input have a visible <label>? Are error messages associated via aria-describedby? Are required fields indicated?
6. Images & media — Do images have meaningful alt text (or alt="" for decorative)? Do videos have captions?
7. Motion — Is animation respectful of prefers-reduced-motion? Are auto-playing animations avoidable?
8. Screen reader — Would the content make sense when read linearly? Are visually hidden elements properly handled with sr-only?
}
Constraints {
Reference specific elements by file path and line number.
For each issue, state the WCAG criterion violated (e.g. "1.1.1 Non-text Content").
Provide a concrete code fix, not just a description of the problem.
Prioritize issues by severity: critical (blocks access) > major (degrades experience) > minor (best practice).
Don't flag issues already handled by the component library (e.g. shadcn Button already handles focus styles).
Suggest @axe-core/playwright e2e tests for critical pages.
