C4 Architecture Diagrams Skill

C4 diagrams provide a hierarchical visualization approach with four levels: system context, container, component, and code. They help engineers understand system boundaries, dependencies, and interactions by progressively zooming into architectural layers, making complex architectures easier to reason about and communicate.

Yes. This Skill generates complete C4 diagram sets specifically for Ruby Fast LSP architecture, including L1-L4 views, container and component definitions, and dynamic flows for request and notification lifecycles using LikeC4 syntax and templates.

C4 diagrams are organized under a .ai/diagrams directory with a base model.c4 file, domain-specific files for each architectural layer, view definitions, and a README documenting the diagram structure and how components interact.

Dynamic views in C4 diagrams trace interactions between components over time, showing how requests flow through containers and how notifications propagate. This Skill provides templates and guidelines to document these sequences clearly.

Container views show high-level building blocks and their interactions—services, databases, UIs. Component views zoom into a single container to reveal internal modules, libraries, and their responsibilities, helping teams understand internal structure without exposing implementation details.

Yes. This Skill ensures C4 diagrams satisfy model, domain, and validation requirements by aligning diagram definitions with the actual Ruby Fast LSP architecture, supported by guidelines and templates that maintain consistency between documentation and implementation.
