Skill: Accessibility Audit

Evaluate against WCAG 2.2 and the project's ARIA patterns.

Steps

Read accessibility/wcag-checklist.md (POUR-organized, P0/P1/P2) and accessibility/aria-patterns.md.
Check the mandatory P0 set per component: keyboard navigable, focus visible (≥3:1), screen-reader name/role/state, contrast (4.5:1 text / 3:1 UI), target size ≥24×24, no color-only signaling.
Verify WCAG 2.2 additions: Focus Not Obscured (2.4.11), Target Size (2.5.8), Accessible Authentication (3.3.8).
Contrast — measure, don't eyeball. For rendered HTML, RUN the real-render gates and report their actual output (CLAUDE.md → Verification Protocol): node scripts/measure_render.mjs <file> [--dark] (every text element) AND node scripts/verify_states.mjs <file> [--dark] (every interactive element in default/hover/focus — catches hover-state failures). For loose color pairs, python3 scripts/contrast.py "<fg>" "<bg>". Never state a ratio you did not measure.
Check reduced-motion handling (taste/motion-choreography.md).

Output

A findings table: WCAG criterion (e.g. 1.4.3) · severity (P0/P1/P2) · what fails · specific fix. Confirm passes explicitly. Accessibility may never be traded for aesthetics.
