You can disable AI attribution in Claude Code commits

By default, Claude Code adds a Co-Authored-By: Claude trailer to every commit. If you want clean commit history without AI attribution, add this to .claude/settings.local.json:

{
  "attribution": {
    "commit": "",
    "pr": ""
  }
}

commit: removes the co-author trailer, pr: removes the Generated with Claude Code footer from PRs. You can also customize the text instead of removing it entirely.
