 # 定时任务 SOP
 
-目录：`../sche_tasks/{pending,running,done}/`
-文件名：`YYYY-MM-DD_HHMM_描述.md`，内容含prompt和schedule
+目录：`../sche_tasks/` 放任务定义JSON，`../sche_tasks/done/` 放执行报告
 
-## 流程
-1. [AUTO]唤醒 → `datetime.now()`取当前时间，`ls ../sche_tasks/pending/`，文件名时间≤当前→到期，选择一个
-2. **立即rename到running/**（先占再读，防多进程重复领）
-3. 读文件执行
-4. 完成→移到done/，**在文件内追加执行报告**供用户查阅
-5. schedule非once→算下次时间，新建文件到pending/
+## 任务JSON格式（*.json）
+```json
+{"schedule":"08:00", "repeat":"daily", "enabled":true, "prompt":"..."}
+```
+repeat可选：daily | weekly | monthly | once | every_Nh（每N小时）| every_Nd（每N天）
 
-注意sche_tasks目录在../，即你的code root下
+## 触发流程
+1. scheduler.py（reflect/）每60秒轮询 sche_tasks/*.json
+2. 条件全满足才触发：enabled=true + 当前时间≥schedule + 冷却时间已过（基于done/最新报告时间戳）
+3. 触发时拼prompt，含报告路径 `../sche_tasks/done/YYYY-MM-DD_任务名.md`
+4. **收到任务后第一件事**：用 update_working_checkpoint 记录报告目标文件路径，防止长任务执行中遗忘
+5. 执行完毕后将报告写入上述路径（scheduler靠此文件判断今天已执行）
+
+## 注意
+- once类型：执行一次后冷却100年（实际效果为永久跳过）
+- 任务文件只管"干什么"，报告路径由scheduler自动生成注入prompt
+- sche_tasks目录在../，即code root下
