助手¶
助手为开发者提供了一种快速简便的方式来修改和版本化智能体，便于实验。
向图结构提供配置¶
我们的task_maistro图结构已经预设了使用助手功能！
它定义了一个configuration.py配置文件并在图中加载。
我们可以在图节点内部访问可配置字段（user_id、todo_category、task_maistro_role）。
创建助手¶
那么，在我们构建的task_maistro应用中，助手有什么实际用例呢？
对我来说，最实用的就是能为不同类别的任务创建独立的待办事项列表。
例如，我想要一个助手管理个人任务，另一个助手管理工作任务。
通过todo_category和task_maistro_role这两个可配置字段，可以轻松实现这种分类配置。
