What is the primary purpose of this skill?

It helps Claude understand, navigate, and maintain the specific folder structure and architectural patterns of a DDD-based NestJS project.

Does it work with any project structure?

While optimized for the Sardius DDD template, its principles can be used to guide Claude in any project requiring strict architectural and naming conventions.

How does it improve code generation?

It ensures Claude places new files in the correct directories (e.g., application vs. infra) and follows the project's specific naming suffixes like .vo.ts or .use-case.ts.

Can it help identify architectural violations?

Yes, by understanding the defined dependency rules, it can flag when a layer is incorrectly importing from a layer it shouldn't access directly.

API Development

Analyzes and enforces Domain-Driven Design (DDD) patterns and folder structures for production-ready NestJS projects.

The Structure Understander skill provides Claude with a comprehensive mental map of complex folder hierarchies and architectural patterns based on the Sardius DDD template. It ensures that code generation and refactoring tasks adhere to strict dependency rules, naming conventions, and layer boundaries (Domain, Infrastructure, and HTTP). By leveraging recursive scanning scripts, this skill prevents architectural drift and ensures that new features are integrated seamlessly into the correct bounded contexts and use cases.
