+## AI-Generated Changes

+When changes were primarily generated by a coding agent (like Claude Code), include the Co-Authored-By attribution in the commit footer:
+
+```
+Co-Authored-By: Claude <noreply@anthropic.com>
+```
+
+This is the only indicator of AI involvement that should appear in commits. Do not add phrases like "Generated by AI", "Written with Claude", or similar markers in the subject, body, or anywhere else in the commit message.
