+# 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:
