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

</p>

`/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

</p>

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 throughout this repo for sound notifications.

```bash
$ claude

> /loop 5m /simplify
> /loop 10m "check deploy status"
```

## ![How to Implement](../!/tags/how-to-implement.svg)

`/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.
