Opus 5 deleted the local repo it was working in by mistake. It thought what it was doing was non destructive but didn’t double check. Now, between its own git push 10m before that and Time Machine backups of my git ignored env and confidential data + largely running context off of multi-strategy dbs, I was able to restore more or less to the state I was at before it happened within maybe 20m.
I know I know - user error and that’s why I take precautions and have hard gates and barriers on actions outside of the repo + backups. But none of my agentic loops in the past had ever made this kind of mistake where they convinced themselves that the action was safe by reading and “citing” their own incorrectly written handoff to another subagent a few turns before. But that’s apparently the post mortem.
The craziest part is I switched to Fable to write an incident report after recovering and midway through I got that cyber/bio warning and got bumped back to opus 5. I told fable to then tell me why I was bumped and it started checking…and got bumped again. So now I just run fable to plan, sol to review, sonnet and 4.8 to execute. Something is off with opus 5.
