Scheduled Tasks Implementation ​

Last Updated: Mar 10, 2026

Implemented

The /loop skill is used to schedule recurring tasks on a cron interval. Below is a demo of /loop 1m "tell current time" -- a simple recurring task that fires every minute.

Loop Demo ​

1. Scheduling the Task ​

/loop 1m "tell current time" parses the interval (1m = every 1 minute), creates a cron job, and confirms the schedule.

Key Notes

  • Cron's minimum granularity is 1 minute -- 1m maps to */1 * * * *
  • Recurring tasks auto-expire after 3 days
  • Jobs are session-scoped -- they live in memory only and stop when Claude exits
  • Cancel anytime with cron cancel <job-id>

2. Loop in Action ​

The task fires every minute, running date and reporting the current time. Each iteration triggers async UserPromptSubmit and Stop hooks -- the same hook system used for sound notifications.

How to Use ​

bash
$ claude
> /loop 1m "tell current time"
> /loop 5m /simplify
> /loop 10m "check deploy status"

How to Implement ​

/loop is a built-in Claude Code skill -- no setup required. It uses the cron tools (CronCreate, CronList, CronDelete) under the hood to manage recurring schedules.
