What problem does it solve? Reviewing a branch or PR requires checking two separate things — whether the code follows the repo's documented standards and whether it actually implements what the issue or PRD asked for — and mixing both in one pass causes one axis to mask the other. ## Core Features & Use Cases - Two-axis review: Runs a Standards review (documented repo standards plus a fixed Fowler code-smell baseline) and a Spec review (requirements coverage, scope creep, wrong implementations) as parallel sub-agents, then reports them side by side. - Fixed-point diffing: Reviews the diff between HEAD and any commit, branch, tag, or merge-base the user supplies, with upfront validation that the ref resolves and the diff is non-empty. - Spec discovery: Locates the originating spec from issue references in commit messages, user-provided paths, or PRD 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 code-review skill.
