Use clear, concise commit messages. -6. Open a pull request targeting main using `gh pr create`: - - The PR title must start with an uppercase letter. Conventional commits prefixes are not required. - - The PR body must be directly usable as a concise commit message: no artificial linebreaks, no markdown formatting, no bullet lists. Write it as plain flowing text that describes what changed and why. -7. After opening the PR, determine who should review it: - - Run `git log --format="%an" -- <affected files> | sort | uniq -c | sort -rn | head -5` to find the most frequent contributors to the affected files. - - Filter out bot accounts (e.g., names containing "bot", "ci", "automation"). - - Assign the top 1-2 human contributors as reviewers using `gh pr edit <number> --add-assignee <username>`. If git log names don't map cleanly to GitHub usernames, use `gh api repos/{owner}/{repo}/commits?path=<file>&per_page=5 --jq '.[].author.login'` to extract GitHub usernames from recent commits to that file. You can get `{owner}` and `{repo}` from `gh repo view --json owner,name`. - - The goal is to notify the people most familiar with the code, not to assign everyone. -8.
