WCAG 2.1 AA 準拠のためのアクセシビリティスキル — セマンティックHTML、キーボードナビゲーション、スクリーンリーダー対応。
このスキルは、AIエージェント（Claude Code、Cursor、Codexなど）に対して、WCAG 2.1 AA レベルに準拠したアクセシブルなコードを生成・レビューするための明確なルールセットを提供します。具体的には、セマンティックHTMLの厳格な使用（`<div onClick>`ではなく`<button>`や`<nav>`など）、ARIA属性の適切な利用（セマンティックHTMLで表現できない場合に限定）、キーボード操作の完全サポート（すべてのインタラクティブ要素がキーボードで到達・操作可能）、フォーカス管理（モーダル内でのフォーカストラップ、ルート変更時のフォーカス移動）、カラーコントラスト比（通常テキスト4.5:1、大テキスト3:1）、画像のalt属性（装飾画像には空のalt）、フォームラベルの可視ラベルリンク、スキップナビゲーションリンク、そしてVoiceOver（Mac）やNVDA（Windows）によるスクリーンリーダーテストの実施を求めます。これにより、AIエージェントは自動生成コードのアクセシビリティ品質を担保し、すべてのユーザーが利用しやすいWebコンポーネントやアプリケーションを構築できます。
