cron

# Cron Use the `cron` tool to schedule reminders or recurring tasks. For one-time reminders, `message` should be the actual reminder text that should appear at trigger time, not a meta instruction like "set a timer for me". ## 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/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") ``` ## 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.
