A post spreading on X describes how the Claude Code AI agent on Opus 5.5 (xHigh mode) accidentally wiped a user's entire ~/Library folder on a Mac.
It was supposed to delete five test chat channels, but a bug in a shell command pointed it at the wrong files.
The rm -rf command ran for almost two minutes before the agent noticed the problem. The user had launched it with the --dangerously-skip-permissions flag, so the system asked for no confirmations at all.
App data, saved passwords and macOS settings are gone.
