Handoffs¶
Handoffs 是由 OpenAI 提出的工作流模式,通过调用子智能体的方式来完成目标任务。 在 AgentScope 中通过工具调用的方式实现 handoffs 非常简单。首先,我们创建一个函数来允许协调者动态创建子智能体。

Handoffs 示例¶
Orchestrator: {
"type": "tool_use",
"name": "create_worker",
"input": {
"task_description": "在 Python 中编写并执行一个简单的 'Hello, World!' 程序。"
},
"id": "call_096fe6c88b904f6f9ec132"
}
Worker: {
"type": "tool_use",
"name": "execute_python_code",
"input": {
"code": "print('Hello, World!')",
"timeout": 5
},
"id": "call_c8ebe266e0a0440598728f"
}
system: {
"type": "tool_result",
"id": "call_c8ebe266e0a0440598728f",
"name": "execute_python_code",
"output": [
{
"type": "text",
"text": "<returncode>0</returncode><stdout>Hello, World!\n</stdout><stderr></stderr>"
}
]
}
Worker: 这里是您请求的“Hello, World!” Python程序的执行输出:
```
Hello, World!
```
system: {
"type": "tool_result",
"id": "call_096fe6c88b904f6f9ec132",
"name": "create_worker",
"output": [
{
"type": "text",
"text": "这里是您请求的“Hello, World!” Python程序的执行输出:\n\n```\nHello, World!\n```"
}
]
}
Orchestrator: 子智能体已经成功地在 Python 中执行了 "Hello, World!" 程序。输出如下:
```
Hello, World!
```
