Can this skill generate diagrams automatically from my code?

Yes, it inspects your repository's entry points, routing, and README files to identify real system boundaries and generate diagrams that reflect the actual implementation.

Can it create UML or Sequence diagrams?

No, this skill is specialized for C4 architecture modeling. It focuses on high-level system structure rather than low-level class or sequence logic.

How does it decide what is a container versus a component?

It follows a strict rule: containers are independent runtime applications or datastores, while components are modular processing units within those containers.

Does it support the Structurizr DSL format?

Yes, the skill is specifically designed to write and revise Structurizr DSL, allowing you to maintain your architecture diagrams as version-controlled source files.

Does it handle visual styling and exports?

It prioritizes getting the model and DSL correct first. Once the model is stable, it provides guidance on adding styles and exporting to build directories.

学習とドキュメンテーション

Generates and refines code-aligned C4 architecture diagrams and Structurizr DSL based on actual codebase structures.

The C4 Architecture Modeling skill empowers Claude to create high-fidelity software architecture diagrams that reflect the ground truth of your codebase. By following the C4 framework (System, Container, Component), it helps developers visualize software boundaries, runtime behaviors, and internal component relationships without inventing abstract layers. It specializes in generating Structurizr DSL, ensuring that architecture documentation remains consistent with the code and provides clear, actionable insights for technical stakeholders and new team members.
