Perform thorough code reviews with security, performance, and maintainability analysis. Use when user asks to review code, check for bugs, or audit a codebase.
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 Skill You now have expertise in conducting comprehensive code reviews. Follow this structured approach: ## Review Checklist ### 1. Security (Critical) Check for: - [ ] **Injection vulnerabilities**: SQL, command, XSS, template injection - [ ] **Authentication issues**: Hardcoded credentials, weak auth - [ ] **Authorization flaws**: Missing access controls, IDOR - [ ] **Data exposure**: Sensitive data in logs, error messages - [ ] **Cryptography**: Weak algorithms, improper key management - [ ] **Dependencies**: Known vulnerabilities (check with `npm audit`, `pip-audit`) ```bash # Quick security scans npm audit # Node.js pip-audit # Python cargo audit # Rust grep -r "password\|secret\|api_key" --include="*.py" --include="*.js" ``` ### 2. Correctness Check for: - [ ] **Logic errors**: Off-by-one, null handling, edge cases - [ ] **Race conditions**: Concurrent access without synchronization - [ ] **Resource leaks**: Unclosed files, connections, memory - [ ] **Error handling**: Swallowed exceptions, missing error paths - [ ] **Type safety**: Implicit conversions, any types ### 3.

How to install
mdr add keyuchen21/agentic-engineering-handbook/code-review@sha256:a64c8c43b4962f26The line at the top of this page pins the label git:20260613.5c7b9b8, 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.
