What is COLA architecture?

COLA (Clean Object-oriented Layered Architecture) is an architectural framework designed to facilitate clean code and DDD by organizing applications into Adapter, Application, Domain, and Infrastructure layers.

Is this skill specific to Java?

While COLA is highly popular in the Java ecosystem (originated by Alibaba), this skill provides architectural patterns applicable to most object-oriented backend environments.

Can I use this for existing projects?

Yes, the skill can analyze your current structure and provide recommendations or refactoring steps to align your project with COLA standards.

How does this skill assist with DDD?

It provides specific guidance on where to place business logic, how to define domain entities, and how to use domain services to prevent logic leakage into other layers.

About

The DDD COLA skill provides Claude with specialized knowledge to implement the COLA (Clean Object-oriented Layered Architecture) framework effectively. It guides developers through structuring projects into distinct layers—Adapter, Application, Domain, and Infrastructure—to ensure a clean separation of concerns and maintainable codebases. This skill is essential for building scalable backend services where complex business logic needs to be decoupled from external frameworks and infrastructure, following industry-standard Domain-Driven Design (DDD) patterns.
