Implements and structures backend applications using the Clean Object-oriented Layered Architecture (COLA) and Domain-Driven Design principles.

This skill provides comprehensive guidance for implementing the COLA V5 architecture, specifically tailored for Java and Spring Boot environments. It helps developers enforce strict layer boundaries between the Adapter, Application, Domain, and Infrastructure layers, ensuring business logic remains pure and decoupled from technical infrastructure. By automating the creation of standard package structures and enforcing dependency rules, it allows teams to build scalable, maintainable microservices that follow industry-standard DDD patterns.
