What is the C4 model used for in this skill?

The C4 model is a lean graphical notation technique for modeling the architecture of software systems using four levels of abstraction: Context, Containers, Components, and Code.

Can I generate diagrams for an existing project?

Yes, the skill can analyze your project structure to identify containers and components, helping you visualize existing legacy systems or new features.

Does this skill require external software to render diagrams?

No, it generates Mermaid syntax which is natively supported by GitHub, GitLab, VS Code, and most modern Markdown editors.

How do I activate the C4 generator?

You can activate it by asking Claude Code for architecture documentation or by mentioning specific terms like 'C4 model', 'system context', or 'container diagram'.

Learning & Documentation

Generates professional C4 model architecture diagrams using Mermaid syntax to document system context, containers, and components.

The C4 Architecture Generator is a specialized skill for Claude Code designed to streamline the creation of technical system documentation. By implementing the C4 model—covering System Context, Container, Component, and Code levels—it allows developers to transform abstract system designs into standardized Mermaid diagrams. This skill is particularly effective for mapping out service boundaries, external dependencies, and internal component relationships, making it an essential tool for maintaining up-to-date Architecture Decision Records (ADRs) and onboarding documentation directly within the development workflow.
