Letting Claude Code Run on Its Own (Carefully)

Claude Code can finish multi-step coding tasks unattended — but only if you fence in what it can touch.

The big idea

Claude Code (Anthropic's terminal agent) can keep working while you go grab a snack. It'll edit files, run tests, fix errors, and try again. Cool — also dangerous if it deletes your project. The trick is fences: only let it touch one folder, only let it run safe commands, and use git so you can undo anything.

Some examples

You start Claude Code in a fresh folder, give it one task, and walk away. It finishes in 4 minutes.
You set the allowed-commands list so it can run `npm test` but not `rm -rf`.
You commit before running it — if it goes wild, `git reset --hard` undoes everything.
You let it loop on 'fix all eslint errors' and come back to a clean lint report.

Try it!

Install Claude Code on a throwaway project. Commit. Give it one bounded task ('fix all type errors'). Walk away for 5 minutes.
