Accessibility Audit

When NOT to use

• For general design system compliance review → use /ss-review
• For Nielsen UX heuristics → use /ss-audit
• For non-StyleSeed code (no data-slot, no semantic tokens) — assumes StyleSeed conventions
• For runtime testing — this is a static code audit, not a screen-reader simulation

Target: $ARGUMENTS

Audit Criteria

WCAG 2.2 AA Compliance

1. Perceivable

• Color contrast: Text must meet 4.5:1 (normal) or 3:1 (large/bold text)
• Check text-muted-foreground (#717182) on bg-background (#FFFFFF) = 4.6:1 (passes)
• Check text-brand on white (verify contrast with your skin's brand color)
• Flag any custom colors that don't meet ratio
• Non-text contrast: UI controls/graphics must meet 3:1
• Text alternatives: All <img> need alt, icons need aria-label when meaningful
• Color independence: Don't convey info by color alone (add icons/text)

2. Operable

• Touch targets: Minimum 44x44px (min-h-11 min-w-11)
• Common violation: h-9 (36px) buttons — should be h-11
• Icon buttons need explicit size: w-11 h-11
• Keyboard navigation: All interactive elements must be keyboard-accessible
• Tab order should be logical
• focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2
• Motion: Animations must respect prefers-reduced-motion

``css @media (prefers-reduced-motion: reduce) { , ::before, *::after { animation-duration: 0.01ms !important; transition-duration: 0.01ms !important; } } ``

3. Understandable

• Labels: Form inputs must have visible labels or aria-label
• Error messages: Form errors must be programmatically associated (aria-describedby)
• Language: <html lang="en"> (or appropriate language code for your project)

4. Robust

• Semantic HTML: Use appropriate elements (<button>, <nav>, <main>, <header>)
• ARIA: Use Radix UI components (they handle ARIA automatically)
• Roles: Custom interactive elements need proper role attributes

Design System Token Reference

| Token | Minimum Contrast | Note | |-------|-----------------|------| | --foreground | 7:1+ | Body text — verify with your skin | | --muted-foreground | 4.5:1+ | Secondary text — verify with your skin | | --brand | 4.5:1+ | Accent — verify with your skin's brand color | | --destructive | 4.5:1+ | Error — verify with your skin | | --success | 3:1+ | Large text/icons only — verify with your skin | | --warning | 4.5:1+ | Warning text — some skins need a darker variant |

Output

1. Issues found: List with severity (Critical/Major/Minor)
2. Auto-fixes: Apply fixes directly where possible
3. Manual review needed: Flag items that need human judgment
