Analyzes code changes for security vulnerabilities, performance issues, and maintainability concerns. Provides structured feedback with SOLID principle checks and anti-pattern detection. Triggers on: "review this code", "code review", "check my PR", "review my changes".
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 Assistant ## Instructions ### Step 1: Gather Context Before reviewing, determine: 1. What language and framework is the code written in? 2. Is this a PR diff, a single file, or a full module? 3. What is the review scope? (Security | Performance | Maintainability | All) If reviewing a PR, ask for the diff or file list. If a single file, ask for the surrounding context (what calls it, what it calls). ### Step 2: Security Analysis Check for these categories in order of severity: **Critical:** - SQL injection (string concatenation in queries) - Command injection (unsanitized shell commands) - Path traversal (user input in file paths without validation) - Hardcoded secrets (API keys, passwords, tokens) **High:** - Missing authentication/authorization checks - Insecure deserialization - SSRF vulnerabilities (user-controlled URLs) - Missing input validation on public endpoints **Medium:** - Missing rate limiting on public APIs - Verbose error messages leaking internals - Missing CSRF protection - Insecure random number generation for security contexts ### Step 3: Performance Review Look for: 1. **N+1 queries** - database calls inside loops …

How to install
mdr add timwukp/agent-skills-best-practice/code-review-assistant@sha256:02f2f224bbeb03b5The 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.
