Code Review Router is an Agent Skill that automatically routes code reviews to the optimal AI tool—either Gemini CLI or Codex CLI—based on code characteristics, complexity scoring, and change patterns. It uses a deterministic decision tree to analyze diffs, detect programming languages, identify security-sensitive code, and calculate complexity scores from 0-10. The skill handles multi-tool orchestration without black-box reasoning, includes automatic fallback handling, and integrates with Git repositories to examine uncommitted changes. Engineering teams benefit from reduced review bottlenecks, consistent routing decisions, and optimized tool selection for different code change types.

1. **Integrate with your VCS:** Connect the router to GitHub/GitLab/Bitbucket using the provided API keys (e.g., GitHub Actions or a custom webhook). Ensure it has read access to PRs, commits, and team member data. 2. **Define team parameters:** Configure expertise criteria (e.g., file paths, language experience) and availability (e.g., GitHub status, calendar sync). Use past review history to refine matches. 3. **Set routing rules:** Customize rules like 'prioritize reviewers with no open PRs' or 'exclude reviewers on vacation.' 4. **Test with a sample PR:** Run a dry test on a non-critical PR to validate the router’s suggestions before full deployment. 5. **Monitor and iterate:** Track review times and conflicts. Adjust criteria based on team feedback (e.g., if certain reviewers are consistently overloaded). **Tip:** Use the router’s output to pre-populate review requests in your VCS (e.g., GitHub’s 'Assignees' field) to save time.
