What is the primary benefit of using the Layered Architecture skill?

It provides a clear framework for separating responsibilities, which prevents 'spaghetti code' and makes the system easier to test, maintain, and understand for new developers.

Can I use this for legacy system modernization?

Absolutely. It is specifically designed to help transition degrading monoliths into structured, N-tier systems by identifying and decoupling layers.

Does this skill help enforce architectural rules automatically?

Yes, it provides guidance on using tools like ArchUnit, ESLint, and custom scripts to catch architectural violations during the CI/CD process.

When should I avoid using a layered architecture?

Avoid this paradigm if your project requires high horizontal scalability through microservices or if the overhead of passing data through multiple layers creates unacceptable latency.

Which programming languages are supported?

The skill includes specific guidance and implementation patterns for Java, TypeScript, C#, and Python, though the concepts can be applied to any modular language.

Implements N-Tier architectural patterns to ensure clear separation of concerns across presentation, domain logic, and data access layers.

概要

This skill guides Claude in implementing the Layered (N-Tier) architecture paradigm, a foundational standard for building maintainable and scalable software systems. It provides systematic guidance on defining architectural boundaries, enforcing strict downward dependency directions, and centralizing cross-cutting concerns like logging and authentication. By using this skill, developers can transform disorganized codebases into structured systems with clear roles for presentation, application logic, and persistence, facilitating easier testing and long-term maintenance in both new projects and legacy modernizations.
