Next.js Adversarial QA & Edge-Case Injection

偏りのないコードレビューと境界値テストを注入するための独立したサブエージェントを起動するワークフローです。

Next.js Adversarial QA & Edge-Case Injection とは?

このスキルは、Next.jsプロジェクトにおいて、開発者の確認バイアスを排除し、コードの堅牢性を高めるための専門的なワークフローを提供します。主な機能は、独立した「敵対的監査サブエージェント」を起動し、開発者が作成したコンポーネントに対して客観的なコードレビューと敵対的エッジケーステストの注入を自動化することです。これにより、開発者が見落としがちな境界値、プロパティの組み合わせ、ネットワークエラー状態、アクセシビリティ、ライフサイクル問題などを徹底的に検証します。重要な原則として、テストコード自体の変更は禁止されており、テストが失敗した場合はコンポーネントの実装を修正する必要があります。このスキルは主にClaude CodeやCursorなどのAIエージェント環境で利用され、pnpmテストランナーを使用した自動テストと自己修復サイクルを備えています。

Next.js 敵対的QA&エッジケース注入 (nextjs-adversarial-qa)

作成者の確認バイアスを排除するために、コードレビューとエッジケーステストを独立した敵対的監査サブエージェントに委任するための特別なワークフロー。

[!TIP] 参考ドキュメント:


アーキテクチャルールと標準

1. 公平な監査人の原則

  • コンポーネントを作成したプライマリエージェントは、エッジケースを自己認定してはなりません。
  • invoke_subagent を使用して独立したサブエージェントを起動し、コードを監査し、敵対的なアサーションを注入する必要があります。

2. 敵対的エッジケースの範囲 ([ComponentName].edge.test.tsx)

サブエージェントは、開発者が頻繁に見落とすシナリオを対象とした [ComponentName].edge.test.tsx を作成する必要があります。

  • 境界値: 空文字列、null/undefined入力、非常に長い文字列、Unicodeおよびペルシャ語RTLグリフ("سلام دنیا")。
  • プロップの組み合わせ: オプションフラグの未処理の組み合わせ。
  • ネットワーク&エラー状態: 非同期拒否、不正なペイロード、低速ストリーム。
  • 深いアクセシビリティとモーション: キーボードナビゲーション(Enter、Space、Tab、Escape)、aria-expanded、aria-busy、aria-live、フォーカストラップ、prefers-reduced-motion。
  • 負荷とライフサイクル: 高速な再レンダリング、アンマウントクリーンアップ、タイマーの後片付け。

3. 不変の敵対的テストの原則

  • テストの修正または緩和は厳格に禁止: 開発者は [ComponentName].edge.test.tsx 内のアサーションを削除または弱めることを許可されていません。
  • テストを修正するのではなく、コードを修正: 敵対的テストが失敗した場合は、コンポーネント([ComponentName].tsx)またはストーリー([ComponentName].stories.tsx)を修正してエッジケースを適切に処理してください。

ワークフローステップ

  • ステップ1: 敵対的監査サブエージェントを起動

    • invoke_subagent を以下の内容で呼び出します:
      • TypeName: "self"
      • Role: "Adversarial Code & QA Auditor"
      • Model: "inherit"
      • Prompt: 監査人に [ComponentName].tsx、[ComponentName]Skeleton.tsx、[ComponentName].test.tsx、[ComponentName].stories.tsx を検査するよう指示し、コンポーネントディレクトリに [ComponentName].edge.test.tsx を生成させます。
  • ステップ2: 監査人が [ComponentName].edge.test.tsx を注入

    • 監査人がエッジケースアサーションを作成し、レビューを完了します。
  • ステップ3: 敵対的テストの実行と自動修復

    • エッジケーステストスイートを実行:
      pnpm test -- <target_component_dir>/[ComponentName].edge.test.tsx
      
    • いずれかのテストが失敗した場合は、すべてのエッジテストがエラー0で合格するまでコンポーネントの実装を修正します。

Always-active code intelligence, search, and navigation skill utilizing the codebase-memory MCP server. Enforces an index-first protocol (verifying and refreshing the knowledge graph via index_repository or index_status before searching, required because background auto_watch is disabled to eliminate editor stutter and system lag), followed by graph-first exploration (search_graph, trace_path, get_code_snippet, query_graph, get_architecture, detect_changes) instead of naive text grep or full-file reads. Always activate before searching the codebase, inspecting unknown architecture, finding symbols, or tracing callers/callees.
