- **Commits:** use the `/commit` skill. Conventional commit format with
  topic-based scope: `type(scope): description`.
- **Pull requests:** use the `/pr` skill.
- **No Claude attribution** — no `Co-Authored-By: Claude`, no "Generated
  with Claude Code" footer.
- **Style:** run `make format` on changed C/C++ before committing; CI
  enforces `make check_format`.
