待辦事項清單
使用 Claude Agent SDK 追蹤和顯示待辦事項，以實現有組織的任務管理
待辦事項追蹤提供了一種結構化的方式來管理任務並向用戶顯示進度。Claude Agent SDK 包含內置的待辦事項功能，可幫助組織複雜的工作流程並讓用戶了解任務進度。
待辦事項生命週期
待辦事項遵循可預測的生命週期：
- 建立為
pending當任務被識別時 - 啟動為
in_progress當工作開始時 - 完成當任務成功完成時
- 移除當群組中的所有任務都完成時
何時使用待辦事項
SDK 會自動為以下情況建立待辦事項：
- 複雜的多步驟任務需要 3 個或更多不同的操作
- 用戶提供的任務清單當提及多個項目時
- 非平凡的操作受益於進度追蹤
- 明確的請求當用戶要求待辦事項組織時
