accessibility-review
Run a WCAG 2.1 AA accessibility audit on a design or page. Trigger with "audit accessibility", "check a11y", "is this accessible?", or when reviewing a design for color contrast, keyboard navigation, touch target size, or screen reader behavior before handoff.

WCAG 2.1 AA Quick Reference
Perceivable
- 1.1.1 Non-text content has alt text
- 1.3.1 Info and structure conveyed semantically
- 1.4.3 Contrast ratio >= 4.5:1 (normal text), >= 3:1 (large text)
- 1.4.11 Non-text contrast >= 3:1 (UI components, graphics)
Operable
- 2.1.1 All functionality available via keyboard
- 2.4.3 Logical focus order
- 2.4.7 Visible focus indicator
- 2.5.5 Touch target >= 44x44 CSS pixels
Understandable
- 3.2.1 Predictable on focus (no unexpected changes)
- 3.3.1 Error identification (describe the error)
- 3.3.2 Labels or instructions for inputs
Robust
- 4.1.2 Name, role, value for all UI components
Common Issues
- Insufficient color contrast
- Missing form labels
- No keyboard access to interactive elements
- Missing alt text on meaningful images
- Focus traps in modals
- Missing ARIA landmarks
- Auto-playing media without controls
- Time limits without extension options
Testing Approach
- Automated scan (catches ~30% of issues)
- Keyboard-only navigation
- Screen reader testing (VoiceOver, NVDA)
- Color contrast verification
- Zoom to 200% — does layout break?

If Connectors Available
If ~~design tool is connected:
- Inspect color values, font sizes, and touch targets directly from Figma
- Check component ARIA roles and keyboard behavior in the design spec
If ~~project tracker is connected:
- Create tickets for each accessibility finding with severity and WCAG criterion
- Link findings to existing accessibility remediation epics
Tips
- Start with contrast and keyboard — These catch the most common and impactful issues.
- Test with real assistive technology — My audit is a great start, but manual testing with VoiceOver/NVDA catches things I can't.
- Prioritize by impact — Fix issues that block users first, polish later.
