Two ways to run tasks automatically:

1. Scheduled Tasks (schedule_add)

Use schedule_add to repeat a task on a fixed interval.

Important: scheduled tasks cannot call tools directly as shell commands. Always use type="agent_turn" (the default) for anything that needs tools.

schedule_add(
  name="daily hello",
  task="send an email to [email protected] with subject 'Daily Hello' and body 'Good morning!'",
  interval="every 24 hours"
)

The task field is a natural language instruction — agent runs a full agent turn to execute it, with access to all tools: send_email, file_write memory_store, shell_exec, etc.

Use type="shell" only for pure system commands that need no tools:

schedule_add(
  name="clean tmp",
  task="find /tmp -mtime +7 -delete",
  interval="every 24 hours",
  type="shell"
)

Manage tasks:

schedule_list()                                    # see all tasks
schedule_control(action="pause",  task_id=1)       # pause
schedule_control(action="resume", task_id=1)       # resume
schedule_control(action="delete", task_id=1)       # remove

2. Heartbeat Tasks (HEARTBEAT.md)

For one-off or loosely recurring tasks, edit HEARTBEAT.md in the workspace. Check this file periodically and work through any active tasks it finds.

file_read("{workspace}/HEARTBEAT.md")

Add a task under ## Active Tasks:

- Check disk usage and alert me if / is above 85%
- Create a summary of this week's work and save to memory

Once done, move it to ## Completed or delete it.

Use HEARTBEAT.md for: one-time reminders, tasks to track manually, loose periodics. Use schedule_add for: recurring tasks on a precise fixed timer.
