规划和执行代理节点#

¥Plan and Execute Agent node

“计划和执行代理”类似于 ReAct 代理，但侧重于计划。它首先创建一个解决给定任务的高级计划，然后逐步执行该计划。此代理最适用于需要结构化方法和周密计划的任务。

¥The Plan and Execute Agent is like the ReAct agent but with a focus on planning. It first creates a high-level plan to solve the given task and then executes the plan step by step. This agent is most useful for tasks that require a structured approach and careful planning.
