# Heartbeat Check List
This file contains tasks for the heartbeat service to check periodically.
## Examples
- Check for unread messages
- Review upcoming calendar events
- Check device status (e.g., MaixCam)
## Instructions
- Execute ALL tasks listed below. Do NOT skip any task.
- For simple tasks (e.g., report current time), respond directly.
- For complex tasks that may take time, use the spawn tool to create a subagent.
- The spawn tool is async - subagent results will be sent to the user automatically.
- After spawning a subagent, CONTINUE to process remaining tasks.
- Only respond with HEARTBEAT_OK when ALL tasks are done AND nothing needs attention.
---
Add your heartbeat tasks below this line:
