cron

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 Suge8/bao 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>")

Timezone-aware cron:

cron(action="add", message="Morning standup", cron_expr="0 9 * * 1-5", tz="America/Vancouver")

List/remove:

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

Time Expressions

User says	Parameters
every 20 minutes	every_seconds: 1200
every hour	every_seconds: 3600
every day at 8am	cron_expr: "0 8 * * *"
weekdays at 5pm	cron_expr: "0 17 * * 1-5"
9am Vancouver time daily	cron_expr: "0 9 * * *", tz: "America/Vancouver"
at a specific time	at: ISO datetime string (compute from current time)

Timezone

Use tz with cron_expr to schedule in a specific IANA timezone. Without tz, the server's local timezone is used.
