ModalityDance Cron
Use the cron tool to schedule reminders or recurring tasks.
Three Modes
- Reminder - message is sent directly to user.
- Task - message is a task description, agent executes and sends result.
- 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:
cron(action="add", message="Check project status and report", every_seconds=600)
One-time task:
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")
Inspect, update, and remove:
cron(action="list")
cron(action="get", job_id="abc123")
cron(action="update", job_id="abc123", every_seconds=1800)
cron(action="remove", job_id="abc123")
Use list to find a job and get to inspect its full schedule, payload, delivery target, and last execution state. update changes only supplied fields. A schedule change replaces the schedule as one unit, so provide exactly one of every_seconds, cron_expr (with optional tz), or at. Use an explicit JSON null to clear channel, to, or session_id.
Remove a job only when the user asks to cancel that scheduled work. Use enable_job when the user wants to pause or resume it without deleting the definition.
