If you're not using .claude/instructions.md yet, I highly recommend it, for moments like this one you can tell it where to shove scripts. Trickery with the instructions file is Claude only reads it during a new prompt, so any time you update it, or Claude "forgets" instructions, ask it to re-read it, usually does the trick for me.

Claude, I noticed you rm -rf my entire system. Your .instructions.md file specifically prohibits this. Please re-read your .instructions.md file and comply with it for all further work
