Code smells like long methods, large classes, and tight coupling indicate where to refactor. Analyze messy code sections to detect these issues, then select appropriate refactoring patterns to reduce complexity and improve maintainability.

The best way to refactor a long method with duplicated logic is applying the Extract Method pattern. This involves identifying distinct functional blocks within the messy method, extracting them into separate well-named methods, and replacing the original code with calls to these new methods.

To apply refactoring patterns after adding features, analyze the hard-to-modify sections to surface actionable refactor steps. Use patterns like Replace Conditional with Polymorphism or Extract Class, following concrete steps and code examples to systematically lower maintenance costs.

Yes, you can get contextual refactoring guidance. The analysis provides concrete steps, rationale, and example snippets tailored to your specific programming language and architecture, ensuring the refactoring patterns are correctly applied across different projects.

You need to use the Extract Class pattern when a single class has grown too large and taken on multiple responsibilities. This refactoring separates distinct responsibilities into new classes to reduce tight coupling and adhere to Clean Code principles.

Automated refactoring suggestions require readable input code to detect smells and propose patterns like Rename or Extract Method. Limitations include handling deeply tightly coupled legacy architectures where isolated pattern application is insufficient without broader architectural changes.
