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 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) |
