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").
