## Summary AI coding tools (Claude Code, GitHub Copilot, etc.) automatically append `Co-authored-by` trailers to commit messages by default: ``` Co-authored-by: Claude Opus 4.8 (1M context) <[email protected]> ``` When PRs are squash-merged on GitHub, these trailers propagate into the merge commit. This makes `git log` look like AI merged the code, which makes it harder for developers to identify who actually authored and reviewed the change. This PR adds a "Commit messages" section to `CLAUDE.md` that instructs AI tools not to include these trailers. ## Changes - Added `## Commit messages` section to `CLAUDE.md` between "Coding conventions" and "Pre-commit checks" - Documents the problem (trailers in squash-merge history) and the fix (omit the line) Fixes #18688 -- This is an automated message from the Apache Git Service.
