| description | Schedule reminders and recurring tasks. |
Use the cron tool to schedule reminders or recurring tasks that should report back to the originating chat/session when they run.
Do not use cron for periodic background checks that should stay quiet when there is nothing useful to report. For those, update HEARTBEAT.md; the protected heartbeat job runs those checks and only delivers results that pass the notification gate.
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>")
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")
| 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) |
Use tz with cron_expr to schedule in a specific IANA timezone. Without tz, the server's local timezone is used.
