SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Document software architecture by generating Mermaid-based C4 diagrams (Context, Container, Component, Deployment, and Dynamic) from project details.

Core Features & Use Cases

  • Generate C4 diagrams in Mermaid syntax at multiple abstraction levels (Context, Container, Component, Deployment, Dynamic).
  • Provide audience-appropriate diagrams and best-practice guidance for executives, architects, and developers.
  • Link outputs to architecture documentation workflows, ADRs, and references to standard patterns.

Quick Start

Create a system context diagram for a project using the Mermaid C4 syntax.

FAQPage Schema
How do I generate C4 architecture diagrams using Mermaid syntax?

To generate C4 architecture diagrams, provide your project details and the tool outputs Mermaid-based visuals for Context, Container, Component, Deployment, and Dynamic levels. It applies C4 conventions automatically to ensure consistent architecture documentation.

What is the best way to document software architecture for different audiences?

Documenting software architecture for different audiences is best handled by generating audience-appropriate Mermaid C4 diagrams. The tool provides guidance and best practices for tailoring visuals to executives, developers, and DevOps with appropriate abstraction levels.

Can I link C4 diagrams to Architecture Decision Records (ADRs)?

Yes, you can link C4 diagrams to ADRs and standard pattern references. The tool enforces C4 conventions and outputs documentation under docs/architecture, integrating architecture visuals directly into your existing documentation workflows.

How do I create a system context diagram in Mermaid for my project?

Creating a system context diagram in Mermaid requires supplying your project details. The tool then generates a Context level C4 diagram that defines the system scope and its interactions with external users and systems.

What Mermaid C4 diagram levels should I use for deployment and dynamic views?

For deployment and dynamic views, use the Deployment and Dynamic C4 diagram levels. The Deployment level shows infrastructure mapping, while the Dynamic level illustrates runtime interactions between components, both generated as Mermaid syntax from your project details.

Does generating C4 diagrams require any external dependencies?

Generating C4 diagrams requires no external dependencies. You only need to provide your project details, and the tool processes them to output Mermaid-based C4 documentation under the docs/architecture directory.
