In a session with permission checks bypassed, Claude wrote a destructive rm -rf as a placeholder in a command and ran it against its own projects folder, then stopped to confess the mistake.

What went wrong

The lesson

Bypassing permission checks removes the last chance to catch a bad command. Keep the prompts on for anything destructive.

What this is. Real projects where people used Claude to build, fix, port, revive or take apart something, from jailbroken Kindles to rebuilt DOS games, plus the times it went badly wrong. Every build links to where it was shared, and every source is listed here.

How far to trust it. We summarise what people reported and say what each build rests on: a full write-up with code, a short post, or a passing comment. We haven't tested them ourselves. Photos are shown from the original sources with credit. Only modify hardware you own, and back up first.

Privacy. No accounts. Analytics cookies (Google Analytics) only if you accept them; no ads or cross-site tracking. Searches are counted anonymously (just the words) to show what's popular, and so are clicks on Ask Claude (just the count).
