Task Types
- One-time: Runs once at a specific time, auto-cleans up after execution
- Recurring: Repeats on a schedule until stopped
Detection rule: Unless "every", "daily", "weekly" or similar keywords are present, the task is treated as one-time.
Examples
/cron-scheduler add "every weekday at 9am" "review yesterday's code commits"
/cron-scheduler add "every 4 hours" "check API health"
