The instruction itself

as written by the author

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:

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

Process:

  • 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
  • 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
  • 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
  • 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
  • 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
  • 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

How to use it

Copy the folder

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
