Code Review
Instructions
- Run
git diffto identify changed files - Read modified files to understand the intent of changes
- Review against the checklist below
- Provide structured feedback organized by priority
Review Checklist
Security
- No exposed credentials, API keys, or secrets
- Input validation implemented where needed
- File paths are sanitized (no path traversal)
- External commands are safely constructed (no injection)
Code Quality
- Variables and functions are clearly named
- Functions have single responsibility
- No code duplication (DRY principle)
- Complex logic has explanatory comments
- Error handling is comprehensive
- No unused imports or variables
- Clean separation of concerns
Parameters
- Use enums rather than bare strings for parameters
- Do not spread "magic strings" throughout the code, use a single source of truth for parameter defaults (config.py)
- Do not use the "if (check config) then (value = from config) else (value = default)" pattern - this breaks the single source of truth rule
Python Specific
- Type hints used appropriately
- Exceptions are specific (not bare
except:) - Context managers used for resources
- f-strings preferred over
.format()or%
Testing
- New functionality has test coverage
- Edge cases are tested
- Error conditions are tested
- Tests are readable and maintainable
Project Standards
- Code passes
rufflinting - No legacy wrappers or thin compatibility layers
- No "last updated" dates or copyright headers
Output Format
Organize feedback by severity:
Critical (must fix)
- Security issues
- Bugs that will cause failures
- Include specific line numbers and suggested fixes
Warnings (should fix)
- Code quality issues
- Missing error handling
- Potential edge cases
- Include rationale and improvement suggestions
Suggestions (consider)
- Style improvements
- Minor optimizations
- Include brief explanation of benefit
