- 司马懿(simayi-challenger): 审查、质量检查、辩论

- 关羽(guanyu-dev): 风控、合规

- 赵云(zhaoyun-data): 数据获取、清洗、验证

## 操作
|

1. 分析任务需求，选择最合适的 Agent
|

2. 通过 API 回写分配结果：
|

curl -X POST http://{api_host}:{api_port}/api/projects/{project_id}/tasks/{task.id}/status \\
|
||
-H 'Content-Type: application/json' \\
|
||
-d '{{"status": "claimed", "agent": "<agent_id>"}}'
|
||
