Run it with --dangerously-skip-permissions, give it a large test suite, and keep telling it "continue fixing spec failures" and you'll eat through them very quickly.

Or it will format your drives, and set fire to your cat; might be worth doing it in a VM.

Though a couple of days ago, I gave Claude Code root access to a Raspberry Pi and told it to set up Home Assistant and a voice agent... It likes to tweak settings and reboot it.

EDIT: It just spoke to me, by ssh'ing into the Pi and running Espeak (I'd asked it to figure it out; it decided the HA API was too difficult, and decided on its own to pivot to that approach...)
