What problem does it solve?

It helps you choose and document the right software design patterns and architecture decisions so your system stays maintainable, consistent, and verifiable as it grows.

Core Features & Use Cases

• Design patterns & architecture principles: Covers implementation and selection guidance for common architectural patterns (e.g., Clean Architecture, DDD, CQRS) and foundational pattern families.
• Architecture decision records (ADR/RFC): Provides templates and practical examples for capturing context, decisions, and consequences.
• Documentation-as-code & diagrams: Supports creating system diagrams with C4 model/Structurizr DSL and diagram-as-code formats like Mermaid and D2.
• Architecture verification in CI/CD: Guides using tools and rules to enforce architectural constraints automatically (e.g., layer dependency rules).

Quick Start

Use this skill to generate an ADR and an architecture rule plan for a new service that follows Clean Architecture and documents key decisions with diagram-as-code outputs.
