Code Quality Review

Perform comprehensive code quality review: $ARGUMENTS

Current State

• Git status: !git status --porcelain
• Recent changes: !git diff --stat HEAD~5
• Repository info: !git log --oneline -5
• Build status: !npm run build --dry-run 2>/dev/null || echo "No build script"

Task

Follow these steps to conduct a thorough code review:

1. Repository Analysis

   • Examine the repository structure and identify the primary language/framework
   • Check for configuration files (package.json, requirements.txt, Cargo.toml, etc.)
   • Review README and documentation for context

2. Code Quality Assessment

   • Scan for code smells, anti-patterns, and potential bugs
   • Check for consistent coding style and naming conventions
   • Identify unused imports, variables, or dead code
   • Review error handling and logging practices

3. Security Review

   • Look for common security vulnerabilities (SQL injection, XSS, etc.)
   • Check for hardcoded secrets, API keys, or passwords
   • Review authentication and authorization logic
   • Examine input validation and sanitization

4. Performance Analysis

   • Identify potential performance bottlenecks
   • Check for inefficient algorithms or database queries
   • Review memory usage patterns and potential leaks
   • Analyze bundle size and optimization opportunities

5. Architecture & Design

   • Evaluate code organization and separation of concerns
   • Check for proper abstraction and modularity
   • Review dependency management and coupling
   • Assess scalability and maintainability

6. Testing Coverage

   • Check existing test coverage and quality
   • Identify areas lacking proper testing
   • Review test structure and organization
   • Suggest additional test scenarios

7. Documentation Review

   • Evaluate code comments and inline documentation
   • Check API documentation completeness
   • Review README and setup instructions
   • Identify areas needing better documentation

8. Recommendations

   • Prioritize issues by severity (critical, high, medium, low)
   • Provide specific, actionable recommendations
   • Suggest tools and practices for improvement
   • Create a summary report with next steps

Remember to be constructive and provide specific examples with file paths and line numbers where applicable.
