check-accessibility

name: check-accessibility description: Review component for accessibility issues disable-model-invocation: true allowed-tools: Read, Grep, Glob, WebSearch, WebFetch

Usage: /check-accessibility COMPONENT_NAME

Examples:

• /check-accessibility button
• /check-accessibility alert
• /check-accessibility v2/lib/src/components/Button.ts

Check accessibility for: $ARGUMENTS

Setup:

1. Read .claude/PROJECT_CONTEXT.md for AgnosticUI structure and accessibility principles

Process:

2. Search for latest standards:

   • Use WebSearch for "WCAG 2.2 [component-type] accessibility"
   • Use WebSearch for "ARIA [specific-pattern] best practices"
   • Fetch W3C WAI-ARIA documentation if needed for specific patterns

3. Locate component files:

   • Core component: v2/lib/src/components/$ARGUMENTS*
   • Framework implementations if relevant: v2/playgrounds/*/src/stories/*$ARGUMENTS*
   • Check PROJECT_CONTEXT for AgnosticUI's accessibility standards location

4. Analyze against current standards:

   • Semantic HTML: Proper element usage for meaning and structure
   • ARIA attributes: Correct, necessary, and following latest specs
   • Keyboard navigation: Tab order, focus management, keyboard shortcuts
   • Focus indicators: Visible focus styles meeting contrast requirements
   • Screen reader support: Meaningful labels, descriptions, live regions
   • Color contrast: WCAG 2.2 AA requirements (4.5:1 text, 3:1 UI)
   • Touch targets: Minimum 44x44px for interactive elements
   • Motion/animation: Respects prefers-reduced-motion

5. Framework-specific considerations:

   • Check if accessibility differs across Lit, React, Vue implementations
   • Verify ARIA is applied correctly in each framework's rendering
   • Test that events work with keyboard in all frameworks

6. Report findings:

   • List issues with severity (Critical/High/Medium/Low)
   • Reference specific WCAG 2.2 success criteria
   • Provide remediation steps with code examples
   • Link to current W3C/MDN documentation
   • Note AgnosticUI-specific patterns to follow

7. If fixes requested:

   • Propose changes that work across all frameworks
   • Ensure fixes align with AgnosticUI's CSS-first approach
   • WAIT FOR USER APPROVAL before implementing

AgnosticUI Accessibility Requirements:

• WCAG 2.1 AA compliance minimum
• Framework-agnostic solutions preferred
• CSS custom properties for focus indicators
• Consistent behavior across Lit, React, Vue
