The /loop command — set Claude to work in the background automatically
Goal: Most people use Claude Code reactively, ask, wait, review, repeat. Today you learn to set tasks running in the background on a timer so Claude Code works while you do other things entirely.
What to do
Open Claude Code
Start Claude Code in your project folder:
claudeSet up an error monitoring loop
Type:
/loop 5m check my project for any errors or broken references and list anything you find. If nothing is wrong, say "All clear."Open a second session and make three changes
While the loop is running: open a second terminal window, start Claude Code, and make three small changes to your project. Use the 4-part formula. Do not close the first window.
Wait for the loop report
Wait 5 minutes. Watch Session 1 — it will automatically run the check again and report what it finds.
Stop the loop
In Session 1, type:
/loop stopExpected result
You set up an automated error monitoring loop. It ran on a timer without you asking. You can now set monitoring running and work on other things while it watches.
Key takeaway
- /loop [interval] [task] sets Claude Code running on a timer. Set it once, let it run, do other things. Use it to monitor for errors during long builds. Stop it with /loop stop.
