What architectural style does this skill promote?

It focuses on the Modular Monolith approach, which organizes code into independent bounded contexts to ensure high cohesion and low coupling.

Does this skill help with data validation?

Yes, it integrates Zod for schema validation at the HTTP layer and enforces domain-level validation within Value Objects and Entities.

Which tech stack is prioritized?

The skill is optimized for TypeScript using the Bun runtime, Hono for the web framework, and Drizzle ORM for PostgreSQL database interactions.

How does it handle communication between contexts?

It advocates for communication through application services and specific interfaces, explicitly forbidding direct domain access between different bounded contexts.

API Development

Architects scalable backend systems using Modular Monolith principles, bounded contexts, and the Hono framework.

This skill transforms Claude into an expert backend architect specialized in building high-performance TypeScript applications using the Bun runtime and Hono framework. It enforces strict domain isolation through bounded contexts and follows Clean Architecture patterns—separating concerns into Infrastructure, Application, and Domain layers. By prioritizing 'Duplication Over Coupling' and a minimal shared kernel, it helps developers build maintainable, enterprise-grade APIs that offer the benefits of microservices isolation with the deployment simplicity of a monolith.
