# Scheduled Reminder
## Definition
Scheduled Reminder定时提醒是一种基于 Cron Job 的主动推送机制——AI Agent 在预设时间自动触发提醒消息,无需用户主动查询。在 [[multi-channel-assistant]] 中展示了定时提醒的典型应用。
## Mechanism
OpenClaw 通过 Cron Job 系统调度定时任务:
- **周一 18:00** → "🗑️ 明天是垃圾清理日"
- **周五 15:00** → "✍️ 该写每周公司周报了"
## Significance
Scheduled Reminder 是 AI Agent 区别于传统问答式 AI 工具的核心特征:
| 被动模式 | 主动模式 |
|---------|---------|
| 用户问AI 答 | AI 定时推送,用户被动接收 |
| 需要用户主动关注 | 用户无需记住,系统主动提醒 |
| 依赖用户记忆 | 零记忆负担 |
