Disabling Claude Code Co-Author Attribution

Properties2

Type	Practice
Note created	May 31, 2026

By default, Claude Code appends a Co-Authored-By: Claude … trailer to git commits and a similar line to PR bodies. To suppress it, set both attribution fields to empty strings in ~/.claude/settings.json (or any .claude/settings.json scope — project or local override):

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

The older includeCoAuthoredBy: false boolean still works but is deprecated in favor of attribution.
