Audit Accessibility

WCAG 2.1 AA compliance review.

When to Use

  • •Before releases
  • •After adding interactive components
  • •Accessibility compliance check

Approach

Step 1: Project Invariants (Required)

Before auditing, check docs/knowledge-base/ for accessibility-specific constraints:

  • •Any documented a11y requirements
  • •Component-specific ARIA patterns
  • •Flag any violation of documented invariants as Critical priority.

Step 2: Focus Areas

Screen Reader

  • • Interactive elements announced correctly
  • • Form labels read properly
  • • Error messages conveyed
  • • Landmarks defined

Keyboard Navigation

  • • All controls reachable via Tab
  • • Focus order logical
  • • Focus visible (ring)
  • • Escape closes modals

Color & Contrast

  • • Text contrast ≥4.5:1 (normal), ≥3:1 (large)
  • • Not relying on color alone
  • • Works with high contrast mode

Motion

  • • Respects prefers-reduced-motion
  • • No auto-playing animations >5s

Step 3: Testing

  1. •Run automated tools (Lighthouse, axe)
  2. •Manual keyboard testing
  3. •Screen reader spot-check

Output

Prioritized findings with WCAG criterion references (e.g., "WCAG 1.4.3 Contrast").
