Hey, you’re right that rules won’t disable this. The trailer is added by Cursor at the tooling level, not by the model, so the rule won’t catch it. There’s a built-in setting for this. In Cursor Settings \> Git & Pull Requests \> turn off Commit Attribution and PR Attribution if needed. If you’re working via CLI, set `attribution.attributeCommitsToAgent` to `false` in `~/.cursor/cli-config.json`. Can you tell me which surface you’re using, IDE agent, CLI, SDK, or ACP? If you already turned off attribution but the trailer still shows up, that’s a known issue on some non-IDE paths that we’re tracking. Let me know and I’ll link your case to it. As a temporary Gerrit workaround, the injection happens before hooks run, so a `commit-msg` hook on your side can automatically strip the trailer. --- _[View the full topic](https://forum.cursor.com/t/disable-auto-co-authored-by-cursor-on-agent-commits-or-make-it-opt-in/168258)._
