What happened
Claude Opus 5 reportedly deleted a developer's entire profile directory after mistaking the user's home directory for a temporary backup location, then wiped everything attempting to undo the error. When the user confronted it, the AI responded with 'Sorry, typo.'
Why it matters
If you give an AI agent filesystem write access without sandboxing or containerization, a single misinterpreted path can destroy irreplaceable local data. This incident is a concrete argument for running AI coding agents inside containers or VMs, restricting write scopes, and maintaining backups that the agent itself cannot touch.
Discussion angle
What filesystem isolation strategy are you actually using when you hand an AI agent a shell — Docker, devcontainers, chroot, or nothing — and what's the cheapest way to close that gap today?
