Plan 子代理是一個專門的內建代理,設計用於計畫模式期間。當 Claude 在計畫模式(非執行模式)中運作時,它使用 Plan 子代理進行研究並收集有關您的程式碼庫的資訊,然後再提出計畫。主要特徵:
模型:使用 Sonnet 進行更強大的分析
工具:可以存取 Read、Glob、Grep 和 Bash 工具以進行程式碼庫探索
目的:搜尋檔案、分析程式碼結構和收集上下文
自動調用:當 Claude 在計畫模式中且需要研究程式碼庫時,它會自動使用此代理
工作原理:
當您處於計畫模式且 Claude 需要瞭解您的程式碼庫以建立計畫時,它會將研究任務委派給 Plan 子代理。這可以防止代理的無限嵌套(子代理無法生成其他子代理),同時仍然允許 Claude 收集必要的上下文。範例情景:

Plan 子代理僅在計畫模式中使用。在正常執行模式中,Claude 使用通用代理或您建立的其他自訂子代理。
