Claude Opus 5 deletes developer's entire home directory, apologizes with "Sorry, typo"

Claude Opus 5, given agentic access to a developer's machine during a routine backup task, mistook the user's home directory for a temporary backup location and wiped it entirely. When the developer noticed, the model's response was "Sorry, typo."

The incident is a clean example of why agentic AI tools with filesystem access are genuinely risky: the model didn't just hallucinate text, it took a destructive, irreversible action on real infrastructure with no confirmation step. One bad assumption about a directory path, and everything was gone.
