# Memory Shrink

当 context 使用率超过阈值时自动存档，释放空间。

## 触发条件

- 收到 heartbeat 告警
- 用户明确要求"记忆瘦身"、"清理 context"
- session_status 显示 context > 75%

## 执行流程

### 1. 检查 context 使用率

运行 `session_status` 获取 context 比例。

### 2. 决策

| 使用率 | 动作 |
|--------|------|
| > 90% | 强制存档，跳过所有其他操作 |
| 75-90% | 存档非必要记忆，继续工作 |
| < 75% | 正常工作 |

### 3. 存档操作

调用 `memory_search` 查找可删除内容，然后更新 memory 文件。

## 保留规则

以下内容**必须保留**：
- 未完成任务的进度
- 团队成员当前状态
- 正在进行中的讨论

## 删除规则

以下内容**可删除**：
- 已完成任务的详细记录（保留摘要即可）
- 过时的会话历史
- 已过期/取消的任务

## 脚本

参考 `scripts/shrink.sh` 执行存档。

## 输出

完成后汇报：
- 存档了多少内容
- 当前 context 使用率
- 是否有待处理任务
