Review the changes since a fixed point (commit, branch, tag, or merge-base) along two axes: Standards (does the code follow this repo's documented coding standards?) and Spec (does the code match what the originating issue/spec asked for?). Runs both reviews in parallel sub-agents and reports them side by side. Use when the user wants to review a branch, a PR, work-in-progress changes, or asks to "review since X".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
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 issue / spec? Both axes run as **parallel sub-agents** so they don't pollute each other's context, then this skill aggregates their findings. The issue tracker should have been provided to you. If not, tell the user to run `/setup-matt-pocock-skills`. ## 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`. Before going further, confirm the fixed point resolves (`git rev-parse <fixed-point>`) and the diff is non-empty. A bad ref or empty diff should fail here, not inside two parallel sub-agents. ### 2. Identify the spec source Look for the originating spec, in this order: …

How to install
mdr add tiagocolombo/hallmark/code-review@sha256:09eb147f793e4647The line at the top of this page pins the label git:20261012.e09dd11, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
