Does this skill support specific frontend frameworks?

While the principles are universal, it includes specific patterns for Feature-Sliced Design (FSD) which is highly effective for modern React, Vue, and Next.js applications.

Can this skill help with complex architectural decisions?

Yes, it provides a structured framework for Clean Architecture and DDD to ensure a clear separation of concerns between your business logic and external infrastructure.

What is the 't-wada' style mentioned in this skill?

It refers to a specific TDD workflow emphasizing a strict Red-Green-Refactor-Commit cycle to ensure continuous progress, high test coverage, and frequent commits.

How does this skill help with refactoring?

It provides standardized techniques such as method extraction, simplifying conditionals, and moving logic to domain entities while maintaining test integrity.
