Cron

A straightforward scheduling tool that handles both static reminders and dynamic tasks where Claude actually executes something each time the cron fires. The three-mode setup is smart: fixed reminders for things like break notifications, recurring tasks where the agent checks GitHub stars or pulls fresh data, and one-time scheduled events that clean themselves up. It supports both simple interval timers (every_seconds) and proper cron expressions for "weekdays at 5pm" scenarios. The dynamic task mode is the interesting bit here, since most cron tools just send you a message, but this one lets Claude run a task description and report back with current results each time.
