Frequently Asked Questions about c4-architecture

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate C4 diagrams from an existing codebase?▼

To generate C4 diagrams, this Skill analyzes your source code to identify system components, containers, and relationships, then outputs the architecture documentation using Mermaid syntax.

What is the C4 model used for in software architecture documentation?▼

The C4 model structures software architecture documentation into Context, Container, Component, and Deployment levels, providing audience-appropriate detail to simplify communication across development teams.

Can I use Mermaid syntax to document software architecture automatically?▼

Yes, this Skill automatically generates C4 model diagrams using Mermaid syntax, ensuring your architecture documentation remains portable and compatible across standard rendering tools.

Does this automated documentation tool require access to source code?▼

Yes, it requires direct analysis of your source code to determine system components and relationships, which is necessary to automatically map the architecture into C4 diagrams.

What's the best way to automate system context diagram generation for software projects?▼

Using this Skill, you can automatically generate system context diagrams by processing your codebase to map high-level system boundaries and relationships in Mermaid syntax.

Are there limitations when using Mermaid for C4 architecture diagrams?▼

Mermaid syntax ensures portability and compatibility for rendering C4 diagrams, but accurate diagram generation depends entirely on the structure and clarity of the underlying source code being analyzed.
