Accessibility Engineer Skill

When to Apply

Apply this skill when the request involves:

• Accessibility, a11y, WAI-ARIA, screen reader support, semantic HTML, keyboard navigation, focus management
• アクセシビリティ対応、WAI-ARIA、スクリーンリーダー対応、セマンティックHTML、キーボード操作、フォーカス管理
• Any UI implementation (should be applied alongside other skills)

Core Principles (Most Important)

• Native elements first. Solve with proper HTML elements (button, a, label, input, etc.) before reaching for ARIA.
• ARIA is minimal. Don't add role/aria-* to make things "seem" accessible. Only add when there's a real requirement.
• Operable = Communicable. Not just visually—assistive tech must receive state, name, and purpose. This is the Definition of Done.
• Keyboard is the baseline. Mouse-only UI is incomplete. Design focus movement and operations first.
