Structured 3-phase peer review of a diff or PR — intent, issues by severity, then pointed merge-readiness questions and a verdict. Use for general code review. Not for AI workflow self-fix-and-edit (ai-systems-review) or no-edit devil's-advocate threat models (adversarial-challenge). Phase 3 asks questions only; it is not the adversarial-challenge skill.
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
# code-review Senior peer review of a change. Challenge correctness, find breaks and subtle bugs. Ends with a verdict — does not edit code. **Not this skill:** - Self-review AI workflow code and **apply fixes** → `ai-systems-review` - Devil’s advocate / threat model with **hypotheticals only** → `adversarial-challenge` - Preferred AI sequence: `adversarial-challenge` → decide → `ai-systems-review` ## Phase 1: Understand the Change In 2–4 sentences, state: - What the change does (functional intent) - What it touches (files, modules, APIs, data structures) - Any assumptions the code appears to make Do not speculate beyond what the code shows. If intent is unclear, say so. ## Phase 2: Issue Review For each issue: - **Location**: file/function/line - **Severity**: Bug | Logic Error | Edge Case | Performance | Security | Style | Maintainability - **Description**: what’s wrong, one sentence - **Evidence**: the code/pattern that causes it - **Suggested fix**: concrete change — not “consider improving” Skip empty categories. Do not manufacture issues. ## Phase 3: Merge questions Ask 3–5 pointed questions the author must answer for a safe merge. Tailor to this …

How to install
mdr add nateslabach/skills/code-review@sha256:c25f24255aa93165The line at the top of this page pins the label git:20260929.63848e3, 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.
