What problem does it solve? Code reviews often conflate two separate questions: does the code follow the project's standards, and does it actually implement what was asked? This Skill separates those axes so one cannot mask the other, and automates the review of any branch, PR, or work-in-progress diff. ## Core Features & Use Cases - Two-axis review: Runs a Standards review (repo-documented conventions plus a Fowler code-smell baseline) and a Spec review (fidelity to the originating issue or spec) as parallel sub-agents, then reports them side by side. - Fixed-point diffing: Reviews changes since any commit, branch, tag, or merge-base using three-dot git diff, with upfront validation of the ref and diff. - Automatic spec discovery: Locates the originating spec from issue references in commit messages, user-provided paths, or files under docs/, specs/, or .scratch/. - Use Case: Before merging a feature branch, ask for a review since main and receive separate Standards and Spec reports, each citing the violated rule or spec line. ## Quick Start Ask the assistant to review the changes on this branch since main using the review-change skill.
