m06-エラーハンドリング は何をしますか？
重要: エラーハンドリングに使用します。トリガー: Result、Option、Error、?、unwrap、expect、panic、anyhow、thiserror、panic vs Resultの返却使い分け、カスタムエラー、エラーの伝播。

このスキルは、主にRust言語でのエラーハンドリングに関する包括的な知識とベストプラクティスを提供します。機能としては、Result型やOption型の適切な使い方、panic!マクロをいつ使用すべきか、エラーの伝播（?演算子）、カスタムエラー型の定義、そしてanyhowやthiserrorといった人気クレートの活用方法をカバーします。開発者はこのスキルを使うことで、Rustにおける堅牢なエラーハンドリング戦略を迅速に実装でき、特に「いつpanicを起こすべきか」と「いつResultを返すべきか」の判断が明確になります。対応プラットフォームは特定のAIエージェント（Claude Code、Cursor、Codexなど）に依存せず、汎用的なRust開発者の知識ベースとして機能します。スキル内部では、エラー処理に関する典型的なコードパターンや思考プロセスが構造化されており、AIエージェントがユーザーのコードに対して適切なエラーハンドリングを提案できるようになります。
