+- **Git commits:** Do NOT add `Co-Authored-By` lines. Keep commit messages short and concise (one line, no verbose descriptions). NEVER commit and push directly to `main`—always use a feature branch and PR.
+- **Git branches:** Use the format `<github_username>/<feature_name>` when creating branches for PRs. Determine the username from `gh api user --jq .login`.
+- **GitHub issues:** When a GitHub issue URL is pasted, fetch all requirements and context from the issue first. The end goal is always a PR with all tests passing.
