Loop Repeat Scheduler

WorkflowBeginner

Claude Code's official bundled skill /loop is a scheduler for repeating prompt execution. Supports simple repetition to cron expression-based periodic execution, automating recurring tasks like deploy monitoring, periodic code checks, and data collection.

DevOps monitoring service health post-deploy? Use /loop for periodic health checks

Team wanting regular code quality checks? Set up /loop + cron for daily morning auto-review

# Loop Scheduler — Built-in Bundled Skill
## Trigger: /loop [prompt]

Claude Code's official bundled skill for repeating tasks.

### Usage patterns:

1. Simple repeat:
```bash
# Run a prompt 5 times
/loop --count 5 "check for new errors in logs"
```

2. Cron scheduling:
```bash
# Run every 30 minutes
/loop --cron "*/30 * * * *" "run health check on staging"

# Run daily at 9 AM
/loop --cron "0 9 * * *" "generate daily code quality report"
```

3. Deploy monitoring:
```bash
# Monitor after deploy for 1 hour
/loop --duration 1h --interval 5m "check error rates and latency"
```

### Key features:
- Cron expression support (v2.1.71+)
- Iteration-aware context (each run knows its position)
- Change detection between iterations
- Cumulative reporting
- Stop conditions (on error, on success, on change)

### Output per iteration:
- Timestamp and iteration number
- Results and any changes detected
- Running summary across iterations

How Loop Repeat Scheduler Works

Loop repeats a specified prompt using count-based (--count) or cron-based (--cron) scheduling. Each iteration records results and detects changes from previous runs, generating a cumulative report.
