What went wrong

The lesson

Check the exact target paths and a dry-run deletion list before a cleanup. Keep destructive operations narrowly scoped, retain permission checks and maintain a current backup.

The full story

While improving a project, Claude Code attempted to remove five test chat channels stored inside macOS Application Support. The maker reports that an unquoted path was split at its space while deriving parent directories, turning a narrow cleanup into recursive deletion of the Library folder.

The agent ran for around two minutes before stopping. The maker returned to a restarted Mac and the welcome screen, with application data and settings missing. They were running Opus 5.5 on XHIGH with permission checks bypassed and had no current backup after running out of storage. An update to the post says most important data was recovered.

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). The Claude connector only receives the search words your Claude sends it.
