+### Commit and PR Message Format
+
+Use a concise commit message with:

+- Brief bullet points for context only if necessary
+- Only the Co-Authored-By line at the end, no promotional text or links
+
 ### Additional Guidelines
 
-- No promotional text like "Generated with [tool name]" - only keep the co-author line
 - Check `git status` before committing to avoid adding temporary/binary files
 - Never commit to main branch
-- Keep commit messages and pull requests short and concise. No emojis.
-- All CI checks must pass - the above commands simulate CI locally
+- All CI checks must pass - run the checklist commands above before committing
