C4 Diagram

Category: Content  ·  Sub-category: content-misc  ·  Last updated:
Use whenever the user wants to draw, sketch, model, or document a C4 architecture diagram (system context, container, component, system landscape, dynamic, deployment), produce Structurizr DSL (.dsl), model microservices and queues at the right C4 level of abstraction, or visualize software architecture in the C4 tradition (Simon Brown). Output is Structurizr DSL ready to render with the user's preferred Structurizr tooling (online editor, local install, IDE plugin). Default focus is system context and container levels; component, dynamic, and deployment views only on explicit request or when complexity demands. Links ADRs via the !adrs directive when the project has them. Composes with sequence-diagram skill (sequence diagrams are not C4 abstractions) and the design-doc skill (which has a C4 section that delegates here). Do NOT use for sequence diagrams, ER diagrams, flowcharts, class/UML diagrams, or non-architectural visualizations.
