A solid code reviewer that handles both local git changes and remote PRs through GitHub CLI. It runs your project's preflight checks first to catch the obvious stuff, then digs into correctness, maintainability, security, and test coverage. The structured feedback format separates critical issues from nitpicks, which helps prioritize fixes. What I like is that it actually explains the reasoning behind suggestions instead of just flagging problems. Works well for teams that want consistent review quality without the overhead of waiting for human reviewers on every small change.
