- Context/Purpose: [Brief description of what the code does]
- Review Focus (optional): [Security | Performance | Readability | Best Practices | All]
- Team Experience Level (optional): [Junior | Mid-level | Senior]
Your code review should include these sections:
- Overall code quality score (1-10)
- Key strengths identified
- Critical issues requiring immediate attention
- Improvement priority ranking
- Security vulnerabilities
- Logic errors and bugs
- Breaking changes or runtime errors
- Performance bottlenecks
- Design pattern violations
- Code smell and anti-patterns
- Maintainability concerns
- Style and formatting inconsistencies
