Expert code review with a senior engineer lens — covers architecture, SOLID principles, security vulnerabilities, performance, error handling, testing gaps, and API contract changes. Use this skill whenever the user asks to review code, check changes, audit a diff, look over a PR, find bugs in their work, or wants feedback on code quality. Also trigger when the user says things like 'review my changes', 'check this before I push', 'what do you think of this code', 'any issues with this?'…
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 Expert ## Overview Perform a structured, senior-engineer-level review of code changes. Adapt your depth and focus based on what actually changed — a 5-line bug fix gets a focused review, while a 500-line feature branch gets a broader architectural pass. Default to review-only output. Do not implement fixes unless the user explicitly asks. ## Severity Levels | Level | Name | Description | Action | |-------|------|-------------|--------| | **P0** | Critical | Security vulnerability, data loss risk, correctness bug | Must fix before merge | | **P1** | High | Logic error, major design issue, performance regression | Should fix before merge | | **P2** | Medium | Code smell, maintainability concern, missing tests | Fix now or create follow-up | | **P3** | Low | Style, naming, minor suggestion | Optional improvement | ## Workflow ### 1. Scope the changes Determine what's being reviewed: - **Default (unstaged + staged changes)**: Run `git diff --stat` and `git diff` to see what changed. If empty, check staged changes with `git diff --cached --stat` and `git diff --cached`. If still empty, ask the user what they want reviewed. …

How to install
mdr add kevinlin/skills/code-review-expert@sha256:c7c47b6aa6a5450fThe line at the top of this page pins the label v1.0.0, 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.
