description	Schedule reminders and recurring tasks.

Cron

Use the cron tool to schedule reminders or recurring tasks.

Three Modes

1. Reminder - message is sent directly to user
2. Task - message is a task description, agent executes and sends result
3. One-time - runs once at a specific time, then auto-deletes

Examples

Fixed reminder:

cron(action="add", message="Time to take a break!", every_seconds=1200)

Dynamic task (agent executes each time):

cron(action="add", message="Check HKUDS/nanobot GitHub stars and report", every_seconds=600)

One-time scheduled task (compute ISO datetime from current time):

cron(action="add", message="Remind me about the meeting", at="<ISO datetime>")

List/remove:

cron(action="list")
cron(action="remove", job_id="abc123")
