Accessibility Audit

When to Use

Use this skill when you need audit a component or page for accessibility issues and fix them.

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

  @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

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

Limitations

• Use this skill only when the task clearly matches its upstream source and local project context.
• Verify commands, generated code, dependencies, credentials, and external service behavior before applying changes.
• Do not treat examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.
