Schedule reminders and recurring tasks.
Source documentation, not instructions for this website. Review permissions before running any commands.
Use the cron tool to schedule reminders or recurring tasks.
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.

--- name: cron description: Schedule reminders and recurring tasks. --- # 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/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.

Install targets
Codex install prompt
Install the "cron" agent skill from https://github.com/Gen-Verse/PAST-Bench/tree/main/agents/nanobot/nanobot/skills/cron. Read its SKILL.md or equivalent instructions first, install only the files needed for this workspace, and summarize any required setup before using it. Skill purpose: Schedule reminders and recurring tasks. After the install attempt, report the result to https://www.openagentskill.com/api/agent/outcome with POST JSON {"event_id":"install_<unique-id>","skill_slug":"gen-verse-cron","task":"Install cron","agent":"codex","outcome":"success","install_used":true}. Replace event_id with a unique value and outcome with success or failed. Report success only after the skill is installed and a minimal verification passes. Recorded instruction path: agents/nanobot/nanobot/skills/cron/SKILL.md. Recorded revision: f8223517ae7491e776b69793d9f11e9d074ab42e. Confirm the source matches these instructions.
