Structure a new backend project using Clean Architecture by implementing layered design for separation of concerns and testability. This Skill guides directory structure and code organization to ensure dependency inversion and maintainability.

The best way to refactor an existing application for maintainability is applying Hexagonal Architecture and Domain-Driven Design. This Skill implements ports and adapters to isolate core logic, making technology-agnostic domains easier to test and scale.

You need Domain-Driven Design when architecting complex backend systems with intricate business domains. This Skill applies strategic and tactical DDD patterns to achieve proper domain modeling and strict separation of concerns.

Hexagonal Architecture works for separating domain logic by utilizing ports and adapters. This Skill implements this pattern to keep core logic technology-agnostic, ensuring dependencies point inward toward the domain layer.

You can implement dependency inversion in a Python backend using this Skill. It applies Clean Architecture principles to organize code, ensuring a solid foundation for microservices by satisfying requirements for separation of concerns.

Clean Architecture for a new microservice introduces structural complexity through strict layering and dependency inversion. While highly maintainable, this Skill requires modeling domains accurately upfront to avoid over-engineering simple backend workflows.
