To apply clean code guidelines during refactoring, analyze your codebase for function size violations and code smells, then implement proper naming conventions and error handling practices to improve code quality.

Clean architecture is a layered design approach that enforces dependency rules to separate business logic from external interfaces. It improves software maintainability by ensuring architectural boundaries are respected, making code easier to modify and test.

Identify code smells by reviewing your code against common anti-patterns and structural violations. Resolve them by applying design patterns, refactoring large functions, and adhering to SOLID principles to achieve maintainable code.

Yes, this approach works for assessing architectural boundaries in existing projects. It evaluates your codebase against clean architecture dependency rules, identifying violations and offering solutions to realign layer interactions for better maintainability.

You should not use clean architecture when a project's scale does not justify strict layered boundaries and dependency rules, as the overhead of separating concerns may outweigh maintainability benefits for small or simple scripts.
