# Contributing Conventions ## PR Title Format PR titles **must** follow the [Conventional Commits](https://www.conventionalcommits.org/) spec. This is enforced by the `semantic-pull-request` CI check. ``` <type>[optional scope]: <description> ``` Allowed types: | Type | When to use | |------|-------------| | `feat` | New feature | | `fix` | Bug fix | | `ci` | CI/CD changes | | `docs` | Documentation only | | `refactor` | Code restructuring without behaviour change | | `test` | Adding or fixing tests | | `chore` | Maintenance (deps, configs, tooling) | | `perf` | Performance improvement | | `build` | Build system changes | | `revert` | Reverts a previous commit | **Do:** ``` ci: retry apt-get installs to handle mirror sync failures feat(grpo): add dataclass config defaults infrastructure fix: preserve RAY_EXPERIMENTAL_NOSET_CUDA_VISIBLE_DEVICES ``` **Don't:** ``` [ci] fix: retry apt-get installs ← area tags are not part of this convention Update stuff Fix bug ``` ## Commit Sign-off All commits must be signed off with `-s`: ```bash git commit -s -m "fix: correct reward normalization" ``` ## CI Triggering After pushing, trigger CI with: ``` /ok to test <full-commit-sha> ``` Use `git rev-parse HEAD` (not the short form) to get the full SHA.
