clean-code

Code review for clean code violations identifies naming issues, overly long functions, mixed abstraction levels, duplication, and error-handling problems. It evaluates SOLID principles to recommend practical changes when responsibilities are muddled or coupling becomes painful.

Refactoring long functions improves structure by breaking them down and making extracted pieces independently readable and testable. It provides concrete refactor suggestions like the extract method to improve clarity and maintainability.

TDD support walks through defining behavior with failing tests and then implementing minimal passing code. The red-green-refactor cycle ensures code changes are guided by test-first development practices to maintain correctness.

Improving error handling shifts from return-code and null patterns toward exception-based approaches. This keeps control flow clean by separating normal logic from error processing logic effectively.

Clean code practices apply universally to improve code readability and maintainability across languages. The guidance focuses on language-agnostic principles like SOLID design, naming conventions, and error handling.
