リソースのライフサイクルを設計する際に使用します。RAII、Drop、リソースライフサイクル、コネクションプール、遅延初期化、リソースクリーンアップパターン、スコープガードなどのキーワードをカバーします。
このスキルは、ソフトウェア開発におけるリソースライフサイクル管理に特化したAIエージェント向けガイドです。RustのRAIIパターンやDropトレイトをはじめ、コネクションプールの設計、遅延初期化（OnceCell, Lazy, OnceLock）、トランザクションやセッション管理、エラー時のクリーンアップ、ガードパターン、スコープガードなど、リソースの安全な確保と解放に関する幅広いトピックを網羅しています。開発者はこのスキルを使うことで、リソースリークを防ぎ、クリーンで予測可能なリソース管理パターンを適用できるようになります。主にRust、Python、C++などの言語を対象とし、Claude CodeやCursor、CodexなどのAIコーディングエージェントで活用できます。また、日本語と英語のキーワード両方で検索可能なため、日本語話者にも使いやすい設計です。

ElevenLabs text-to-speech with mac-style say UX.
Oracle CLI second-model review/debug/refactor/design with selected files, dry-run token checks, API or browser engine.
Capture and automate macOS UI with the Peekaboo CLI.
Generate multiple radically different interface designs for a module using parallel sub-agents. Use when user wants to design an API, explore interface options, compare module shapes, or mentions "design it twice".
Build a throwaway prototype to flesh out a design — a runnable terminal app for state/business-logic questions, or several radically different UI variations toggleable from one route.
Interview the user relentlessly about a plan or design until reaching shared understanding, resolving each branch of the decision tree. Use when user wants to stress-test a plan, get grilled on their design, or mentions "grill me".
