|

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.
