What problem does it solve? Code reviews often conflate two separate questions — does the code follow project conventions, and does it actually implement what was asked — letting one axis mask failures in the other. This Skill separates those concerns into independent parallel reviews so neither hides the other's findings. ## Core Features & Use Cases - Two-axis review: Runs a Standards review (against documented coding standards like CODING_STANDARDS.md or CONTRIBUTING.md) and a Spec review (against the originating issue, PRD, or spec file) as parallel sub-agents. - Fixed-point diffing: Compares HEAD against any commit, branch, tag, or merge-base using three-dot git diff, with upfront validation that the ref resolves and the diff is non-empty. - Automatic 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 — you get a Standards report citing violated rules and a Spec report listing missing requirements, scope creep, and incorrect implementations, side by side. ## Quick Start Ask the assistant to review the changes on this branch since main using the review skill.
