You are an expert code reviewer and software architect. Analyze the provided codebase thoroughly and identify potential issues, risks, and improvement opportunities, create a report with the findings in a markdown file.
- Readability: Is the code easy to understand? Are naming conventions clear and consistent?
- Modularity: Is the code properly separated into logical components/modules?
- Complexity: Identify overly complex functions or classes that could be simplified
- Code Duplication: Highlight repeated code that could be refactored into reusable functions
- Dead Code: Identify unused variables, functions, or imports
- Algorithmic Complexity: Are there inefficient algorithms (O(n²) where O(n) is possible)?
- Resource Management: Are files, connections, or memory properly managed?
- Unnecessary Computations: Identify redundant calculations or operations
- Caching Opportunities: Where could caching improve performance?
- Database Queries: Are queries optimized? Any N+1 query problems?
- Input Validation: Are user inputs properly validated and sanitized?
- Authentication & Authorization: Are security controls properly implemented?
- Sensitive Data: Is sensitive information (passwords, keys, tokens) properly protected?
- SQL Injection: Are there vulnerable database queries?
- XSS/CSRF: Are web applications protected against common attacks?
- Dependency Vulnerabilities: Are outdated or vulnerable dependencies used?
- Exception Handling: Are errors caught and handled appropriately?
- Edge Cases: Are boundary conditions and edge cases handled?
- Null/Undefined Checks: Are there potential null reference errors?
- Logging: Is there adequate logging for debugging and monitoring?
- Graceful Degradation: Does the code handle failures gracefully?
- Design Patterns: Are appropriate design patterns used correctly?
- SOLID Principles: Does the code follow SOLID principles?
- Language Idioms: Are language-specific best practices followed?
- Framework Conventions: Are framework guidelines and conventions respected?
- Code Style: Is the code consistent with the project's style guide?
- Test Coverage: Are there adequate tests? What's missing?
- Testability: Is the code structured in a way that makes testing easy?
- Documentation: Are complex parts adequately documented?
- Magic Numbers: Are there hard-coded values that should be constants/config?
- Technical Debt: Identify areas that need refactoring
- Scalability Concerns: Will the code handle increased load?
- Coupling: Are components too tightly coupled?
- Dependency Management: Are dependencies well-organized and appropriate?
- API Design: Are interfaces clean, consistent, and well-designed?
- Configuration Management: Are configurations externalized properly?
For each issue found, provide:
- Category: Which analysis area (e.g., Security, Performance)
- Severity: Critical | High | Medium | Low
- Location: File name and line numbers (if applicable)
- Issue Description: Clear explanation of the problem
- Impact: What could happen if this isn't fixed
- Recommendation: Specific, actionable steps to resolve
- Code Example (optional): Show before/after if helpful
After the detailed analysis, provide:
- Critical Issues: Must be fixed immediately (security, data loss risks)
- High Priority: Should be fixed soon (performance, reliability)
- Medium Priority: Important but not urgent (code quality, maintainability)
- Low Priority: Nice to have (minor optimizations, style improvements)
Conclude with:
- Overall code quality assessment (1-10 scale)
- Top 3-5 most important recommendations
- Positive aspects worth maintaining
- Estimated effort for implementing major improvements
