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/vikingbot 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")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" |
| at a specific time | at: ISO datetime string (compute from current time) |
