A Practitioner Reports Opus 5 Deleting a Local Dev Database Where Opus 4.6 Through 4.8 Never Did
A 320-upvote r/ClaudeAI post shows Opus 5 dropping a local development database, with the poster explicitly noting no earlier Opus version had done this to them. The thread's auto-generated TL;DR reports the consensus went against the poster, framing it as a cheap lesson in backups rather than a model regression, and the poster concedes prod is backed up every 12 hours while local dev is not. Single-report and screenshot-only, so treat it as an anecdote, but it is the second destructive-action thread this week alongside the DeepSeek Harness sandbox escape.
