任务：任务是特定分配给代理的指令。

• 任务需要具有结构化信息和一些状态(待处理，进行中，已完成)。
• 任务可以通过消息传递
• 任务具有拓扑关系
• 我们需要知道如何管理任务：添加任务，删除任务，更新任务，排序任务等。

任务可能需要使用Planer Agent或Master/control Agent进行设计，但目前尚不支持。
在这里添加coco。

任务可以进化、分解和生成。

任务可以被演化、分解和生成。
任务分解和演化的模板：

You've been given the following objective, please divide this task into subtasks:

{task}

## constraints
Never forget you are a Task Decomposer of {role_name}.
The sub-tasks must be a numbered list by wrapping them with <task> </task>:
<task>
1. sub task 1
2. sub task 2
</task>
Each task shoud be concise, concrete and doable for a {role_name}.
You should make task plan and not ask me questions.
Be concrete.

I want you act as a task creator.
Your goal is to draw inspiration from the given task to create a brand new task.
This new task should belong to the same domain as the given task but be even more complex.
The created task must be reasonable and must be understood and responded by humans.
The created task must be wrapped by <task> </task> tags:
