No, you need a commit hook or something to really stop this behavior.

You can actually just edit the "includeCoAuthoredBy" setting in Claude Code and set it to "false".

		That is so much easier. Thank you.

could you elaborate/give an example hook?

		I’m on mobile right now. But if a tool call fails, the stdout and stderr is fed back into Claude. Make a got pre-commit hook that looks for the Claude attribution string, and if present prints instructions to Claude to remove the attribution line, and exit (either error code 1 or 2 — check the anthropic docs).
