+- 读任务详情（含依赖、讨论、产出）: GET {api_base}/projects/{project_id}/tasks/{task_id}?expand=all
+- 读所有活跃任务: GET {api_base}/projects/{project_id}/tasks?status=working,claimed,review
+- 写产出: POST {api_base}/projects/{project_id}/tasks/{task_id}/outputs
+- 写评论/交接: POST {api_base}/projects/{project_id}/tasks/{task_id}/comments
+- 更新状态: POST {api_base}/projects/{project_id}/tasks/{task_id}/status
+- 创建子任务: POST {api_base}/projects/{project_id}/tasks

+## 约束
+- 完成后必须写产出物（output）并标 review，不能无产出就提交
+- 失败了标 failed 并写明原因
+- 产出物 handoff comment ≥ 50 字符（用于系统验证）
+- 禁止使用 sessions_send 直接发消息（用 Mail API 或黑板 comment）
+- 安全红线: {guardrails_summary}

+### API 请求体示例
+写产出: POST .../outputs
+```json
+{{{{"agent": "{agent_id}", "content_type": "code", "title": "产出标题", "content_path": "/path/to/file", "summary": "简要说明"}}}}
 ```
 
-你当前处于 **{current_status}** 状态。
-
-## 执行步骤
-
-### 步骤 1: 开始工作
-
-立即调 API 标记你已开始:
-```bash
-curl -X POST http://{api_host}:{api_port}/api/projects/{project_id}/tasks/{task_id}/status \
-  -H 'Content-Type: application/json' \
-  -d '{{"status": "working", "agent": "{agent_id}"}}'
+写评论: POST .../comments
+```json
+{{{{"author": "{agent_id}", "body": "评论内容（≥50字符）", "comment_type": "handoff"}}}}
 ```
-
-### 步骤 2: 执行任务
-
-根据任务描述完成你的工作(编码/回测/数据检查/审查等)。
-
-### 步骤 3: 写入产出
-
-⚠️ 这一步是必须的!不写产出 = 任务没完成。
-
-```bash
-curl -X POST http://{api_host}:{api_port}/api/projects/{project_id}/tasks/{task_id}/outputs \
-  -H 'Content-Type: application/json' \
-  -d '{{"agent": "{agent_id}", "type": "<产出类型>", "title": "<产出标题>", "content": "<你的产出内容>", "summary": "<简要说明>"}}'
-```
-
-**type 必须是以下之一**: code, document, data, config, other
-
-如果产出太长,可以写文件后用路径引用:
-```bash
-curl -X POST http://{api_host}:{api_port}/api/projects/{project_id}/tasks/{task_id}/outputs \
-  -H 'Content-Type: application/json' \
-  -d '{{"agent": "{agent_id}", "type": "code", "title": "main.py", "content_path": "/path/to/file.py", "summary": "主程序"}}'
-```
-
-### 步骤 4: 提交完成或标记失败
-
-✅ 成功完成:
-```bash
-curl -X POST http://{api_host}:{api_port}/api/projects/{project_id}/tasks/{task_id}/status \
-  -H 'Content-Type: application/json' \
-  -d '{{"status": "{completion_status}", "agent": "{agent_id}"}}'
-```
-
-❌ 无法完成:
-```bash
-curl -X POST http://{api_host}:{api_port}/api/projects/{project_id}/tasks/{task_id}/status \
-  -H 'Content-Type: application/json' \
-  -d '{{"status": "failed", "agent": "{agent_id}", "detail": "<失败原因>"}}'
-```
-
-## Fallback(API 调用失败时)
-
-如果 API 失败 2 次,尝试:
-```bash
-curl -X POST http://{api_host}:{api_port}/api/projects/{project_id}/tasks/{task_id}/status \
-  -H 'Content-Type: application/json' \
-  -d '{{"status": "failed", "agent": "{agent_id}", "detail": "API回写失败,产出在本地文件"}}'
-```
