What triggers me is how insistant Claude Code is on adding "co-authored by Claude" in commits, in spite of my settings and an instruction in CLAUDE.md. I wish all these tech bros were as willing to credit the human shoulders on which their products are built. But they'd be much less successful in our current system if they were that kind of people.
Try changing the system prompt or switch to opencode [0] - they allegedly reverse engineered Claude Code, and so the performance you get with Claude models should be very similar to Claude Code.

there's an option for claude to disable co-authoring, see: https://code.claude.com/docs/en/settings
{ "includeCoAuthoredBy": false }
I've changed the settings and added the instruction to the prompt, hence my frustration :)
