 **用途**：N个独立同构子任务分发，独立上下文避免交叉污染
 **约束**：文件系统共享(优点)；键鼠不可共享；浏览器避免同tab
 **流程**：准备独立输入文件→每个启动subagent(--func优先)→收集输出汇总

-## subagent内部plan_mode使用
-**原则**：subagent本身是完整agent，接收多步骤任务时应在内部创建plan管理执行
-**触发条件**:任务包含3个以上子步骤、子步骤之间有依赖关系、需要checkpoint来恢复执行
-**实现方式**：
-1. **主agent创建subagent时**：在input.txt中说明任务包含多个步骤，建议使用plan_mode
-2. **subagent内部执行**：检测到多步骤任务后，创建 `./subagent_plan.md` 并使用plan_mode执行
-3. **主agent监控**：只关注最终结果（output*.txt），不需要关心subagent内部如何执行
-4. **文件传递机制**：主agent创建subagent时在task_dir中生成 `context.json`，包含所有文件的**绝对路径**
-   **⚠ subagent启动后第一步必须读取context.json**
-   **⚠ 所有文件操作必须使用context.json中的绝对路径**
-**格式示例**：
-```json
-{
-  "task": "任务描述",
-  "work_dir": "/absolute/path/to/plan_dir/",
-  "input_files": {
-    "paper_info": "/absolute/path/to/paper_info.txt"
