# graceful-restart skill

## 触发条件

当用户要求重启 Gateway 时,自动触发此 skill。

## 问题背景

Gateway 重启后,会丢失上一轮会话的任务上下文,导致:
- 主会话被中断,无法自动恢复
- 需要用户手动发送消息才能继续

## 功能

自动执行"重启后自唤醒"流程:
1. 设置一次性 cron 任务(默认 10 秒后触发)
2. 执行 Gateway 重启
3. 重启后自动发送消息到主会话

## English Description

**Problem:** After Gateway restarts, OpenClaw loses the previous session context - the main session is interrupted and cannot resume automatically.

**Solution:** Auto-restart Gateway with self-wakeup. Sets a one-time cron task (default 10s) before restart, then sends a message to main session after Gateway recovers to resume tasks.

**⚠️ Important: Must use this skill, NOT exec:**
```bash
# ✅ Correct
node ~/.openclaw/workspace/skills/graceful-restart/graceful-restart.js --task "config changed"

# ❌ Wrong
exec openclaw gateway restart  # Don't do this!
```

**Trigger:** "重启", "restart Gateway"

## 使用方式

用户说"重启"时,自动执行:
```
[自动触发 graceful-restart skill]
```

或者用户可以指定任务:
```
重启 Gateway,继续之前的任务:安装 Python 包
```

## 命令行调用

```bash
node ~/.openclaw/workspace/skills/graceful-restart/graceful-restart.js
node ~/.openclaw/workspace/skills/graceful-restart/graceful-restart.js --task "继续安装 Python 包"
node ~/.openclaw/workspace/skills/graceful-restart/graceful-restart.js --task "继续安装 Python 包" --delay 60
```

## 实现原理

使用 `--session main` + `--system-event`:
- Cron 在主会话里注入一个 system event
- Gateway 重启后,heartbeat 轮询到并交付给主会话
- 主会话收到消息后回复用户

## 注意事项

- Cron 任务时间可调整(默认 10 秒)
- 使用 `--delete-after-run` 确保一次性任务自动清理

## 📝 更新 SOUL.md

使用此 skill 后,建议在 `SOUL.md` 中添加自动触发规则(见上方)。

## ⚠️ 重要:禁止使用 exec

Gateway 重启**必须使用此 skill**,禁止直接用 exec 执行:

✅ **正确:**
```bash
node ~/.openclaw/workspace/skills/graceful-restart/graceful-restart.js --task "配置已修改,需要重启后生效"
```

❌ **错误:**
```bash
exec openclaw gateway restart  # 禁止!
```
