はじめに Claude Code v2.0.28のアップデートによりPlan機能がサブエージェント化されました。Plan生成時のコンテキストが切り出され、メインコンテキストの削減に繋がるのが主な利点ですが、この影響でPlanモード実行時に利用されるツールがビルトインツールのみに制限され、MCPサーバーから提供されるツール(Serenaツールを含む)が使用できなくなりました。 Serenaユーザーから「ツールが使われなくなった」という報告を受けた著者はこの問題を特定し、Planエージェントを上書きすることでSerenaツールをサポートする方法を試みました。その結果、うまく動作したので知見を共有します。 💡注意: これは公式にサポートされている方法ではないため、将来のアップデートで動作しなくなる可能性があります。Claude Codeの柔軟なプラグイン機構のおかげで、さまざまなカスタマイズが可能で面白いですね。 この記事では、Serena MCPサーバーのツールを使用したカスタムPlanサブエージェントの使い方を説明します。 概要 このカスタムPlanサブエージェントは、C
