I've gotten the `git reset --hard` with Claude Code as well, just not immediately after (1)) explicitly pushing back against the idea or (2) it talking a bunch of shit about another agent's totally reasonable analysis.

I exclusively used sonnet when I used Claud Code and never ran into this, so maybe it's an Opus thing, or I just got lucky? Definitely has happened to me a few times with Codex (which is what I'm currently using).
