Accessibility Checker (Haiku)
Purpose: Quick A11y review - WCAG 2.1 checklist, screen reader compatibility, keyboard navigation, color contrast.
Model: Haiku 4.5 (fast accessibility checking)
When to Invoke Autonomously:

- Screen Reader Test: "Will screen readers handle this correctly?"
- Keyboard Navigation: "Can users navigate without mouse?"
DO NOT invoke for:
- Comprehensive audits (use specialized tools)
- Already-accessible code
Usage
/accessibility-checker review [component]
/accessibility-checker wcag-check [page/component]
/accessibility-checker keyboard-nav [interactive elements]
