What Review Code does

Review code changes against repo coding standards and spec requirements in two isolated axes (Standards and Spec). Use when reviewing branches, WIP, or requesting a diff review from a specific point.

Review Code is cataloged under Quality on DirSkills. Review Code comes from a repository tagged agent-skills and go.

Documentation

README

Excerpt

Two-axis review of the diff between HEAD and a fixed point the user supplies:

Standards — does the code conform to this repo's documented coding standards?
Spec — does the code faithfully implement the originating spec / PRD?

The two axes are reviewed in isolation so they don't pollute each other, then aggregated side by side.

Process

1. Pin the fixed point

Whatever the user said is the fixed point — a commit SHA, branch name, tag, main, HEAD~5, etc. If they didn't specify one, ask for it.

Capture the diff command once: git diff <fixed-point>...HEAD (three-dot, so the comparison is against the merge-base). Also note the list of commits via git log <fixed-point>..HEAD --oneline.

This is the opening of the README. Read the full README on GitHub.
