To refactor legacy code for maintainability, apply DRY to extract duplicated logic into reusable modules and SRP to ensure each service has a single responsibility, reducing defects and churn.

Language-agnostic clean code review checks for DRY, KISS, and YAGNI violations, enforcing structured guidance and corrective recommendations across projects of varying sizes from scripts to services.

Use dependency inversion (DIP) to promote modular design and fail fast to validate inputs at public boundaries, catching errors early before they propagate through the system architecture.

Yes, these language-agnostic clean code principles guide code generation, review, and refactoring tasks effectively across projects of varying sizes, from standalone scripts to complex modular services.

Premature optimization violates the KISS principle by favoring cleverness over readability, and YAGNI by adding unnecessary complexity, which increases defects and code churn over time.

Begin code generation by auditing for DRY, SRP, and proper input validation, using structured guidance and examples to enforce maintainable coding standards from the start.
