cron
Schedule and manage recurring or one-time jobs for main/project agents.
Best use case
cron is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Schedule and manage recurring or one-time jobs for main/project agents.
Teams using cron should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Cron Use the `cron` tool to create, list, remove, enable/disable, and run scheduled jobs. ## Actions - `add`: create a job - `list`: show jobs - `remove`: delete a job by id - `enable`: enable or disable by id - `run`: run a job now ## Add Examples Daily at 8:00: ``` cron(action="add", message="Report yesterday's progress", cron_expr="0 8 * * *") ``` Every 30 minutes: ``` cron(action="add", message="Check project status", every_seconds=1800) ``` Target a student/project agent: ``` cron(action="add", target="proj:project-id", message="Summarize blockers", cron_expr="0 9 * * 1-5") ``` One-time reminder: ``` cron(action="add", message="Prepare meeting notes", at="2026-03-10T14:00:00") ``` ## Notes - If `target` is omitted, default is `main`. - For `add`, provide exactly one of: `every_seconds`, `cron_expr`, `at`. - `tz` can be used only with `cron_expr`.
