Claude Code /loop: Session-Scoped Lightweight Recurring Task Scheduler with Cron Syntax

Claude Code Docs·medium signal

The /loop bundled skill schedules a prompt to repeat at a fixed interval while the Claude Code session stays open, using syntax like '/loop 5m check the deploy' or /loop with --cron for five-field cron expressions targeting specific times or weekdays. Tasks are session-scoped with a 3-day auto-expiry, do not fire catch-up runs for missed intervals, and cancel cleanly when the terminal closes — making them appropriate for lightweight monitoring loops, build health checks, and incremental file syncs without external cron infrastructure. For durable scheduling that survives terminal close, pair with /schedule in Claude Cowork or GitHub Actions.
