Recommended reviewers are automatically + assigned to the PR via the GitHub API. +- **PR risk assessment** -- `/risk` slash command posts a detailed risk + breakdown (size, sensitive paths, test coverage, contributor history, revert + detection, dependency changes, breaking changes, and matched Watchflow rule + severity).
