Can I use this skill before converting DTOs?

No, this skill is the last step in a cycle. It requires that the request/response DTOs, persistence layer, and service layer have already been migrated.

What files does this skill specifically generate?

It generates LegacyQueryV1Controller.java and LegacyV1ApiMapper.java files tailored to the specific domain and controller method provided.

What is the purpose of the legacy-controller skill?

It automates the final phase of migrating a legacy endpoint by generating the Controller and ApiMapper components based on previous migration steps.

Does it support different types of APIs?

Yes, it handles both Admin API and Web API structures, placing files in the appropriate 'adapter-in' directory paths.

How does it help with code consistency?

By using a generator, it ensures that every migrated controller follows the exact same pattern, directory structure, and naming conventions across the project.

API Development

Automates the final stage of backend migration by generating REST controllers and API mappers for legacy system modernization.

The legacy-controller skill is a specialized tool designed to perform the final step in a multi-stage legacy system migration workflow. It bridges the gap between the application layer and external consumers by automatically generating Java REST controllers and ApiMapper components. It follows strict architectural patterns for both Admin and Web API contexts, ensuring that external requests are correctly mapped to internal use cases and that response data is consistently formatted. This skill ensures that once the DTOs, persistence, and services are migrated, the entire end-to-end endpoint flow is completed with standardized naming and directory structures.
