Code Reviewer Agent Skill

Code Reviewer

Complete toolkit for code reviewer with modern tools and best practices.

Routing Boundary

Use code-reviewer when the user asks for a fresh review of code or a PR:

• correctness and likely bugs
• maintainability and readability
• regression risk
• test coverage gaps from a reviewer's point of view

Do not let this skill own narrower problems:

• security-reviewer owns OWASP, secret leak, auth bypass, injection, and dedicated security audit prompts.
• receiving-code-review owns existing CodeRabbit/GitHub/human review comments.
• verification-before-completion owns final evidence before claiming work is done.
• deslop owns cleanup of AI-generated comments, redundant guards, and boilerplate.
• tdd-guide owns test-first or RED -> GREEN -> REFACTOR development.

Migrated Legacy Assets

The legacy review wrapper has been absorbed into this direct route owner.

• references/python-style-guide.md contains the retained Python naming, import, documentation, error-handling, and secret-handling guidance.
• scripts/check_style.py is a lightweight stdin/string style checker for quick local review support.

Use these assets as supporting material inside code-reviewer; do not route to the deleted wrapper skill.

Quick Start

Main Capabilities

This skill provides three core capabilities through automated scripts:

# Script 1: Pr Analyzer
python scripts/pr_analyzer.py [options]

Development Workflow

1. Setup and Configuration

# Install dependencies
npm install
# or
pip install -r requirements.txt

# Configure environment
cp .env.example .env

2. Run Quality Checks

# Use the analyzer script
python scripts/code_quality_checker.py .

# Review recommendations
# Apply fixes

3. Implement Best Practices

Follow the patterns and practices documented in:

• references/code_review_checklist.md
• references/coding_standards.md
• references/common_antipatterns.md

Best Practices Summary

Code Quality

• Follow established patterns
• Write comprehensive tests
• Document decisions
• Review regularly

Performance

• Measure before optimizing
• Use appropriate caching
• Optimize critical paths
• Monitor in production

Security

• Flag obvious security risks during a general review.
• Route dedicated OWASP, auth, secret, injection, or threat-model requests to security-reviewer.

Maintainability

• Write clear code
• Use consistent naming
• Add helpful comments
• Keep it simple

Common Commands

# Development
npm run dev
npm run build
npm run test
npm run lint

# Analysis
python scripts/code_quality_checker.py .
python scripts/review_report_generator.py --analyze

# Deployment
docker build -t app:latest .
docker-compose up -d
kubectl apply -f k8s/
