accessibility-audit

Purpose

Verify that a web application meets WCAG 2.2 Level AA — the standard required by ADA, EN 301 549, and most accessibility laws globally. Produces a prioritized violation report with WCAG criterion IDs, severity, and concrete fixes.

Trigger

Apply when:

• "accessibility audit", "WCAG compliance", "a11y audit", "無障礙檢查"
• "screen reader compatibility", "keyboard navigation audit", "color contrast check"
• Pre-launch accessibility gate, legal compliance review, user complaint about inaccessibility

Do NOT trigger for:

• General UI/UX review — use senior-frontend instead
• Performance audits — use performance-profiler instead
