SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill bridges the gap between detailed code-level documentation and higher-level architectural views by synthesizing code elements into logical C4 components.

Core Features & Use Cases

  • Component Synthesis: Identifies logical component boundaries from code documentation.
  • Interface Definition: Documents component APIs, protocols, and data contracts.
  • Diagram Generation: Creates C4 Component-level diagrams using Mermaid syntax.
  • Use Case: After documenting individual code files, use this Skill to group them into cohesive components like 'UserService' or 'PaymentProcessor' and visualize their interactions within a container.

Quick Start

Synthesize all c4-code-*.md files into logical components and generate component diagrams.

FAQPage Schema
How do I generate C4 component diagrams from code-level documentation?

To generate C4 component diagrams from code-level documentation, synthesize code elements into logical components by identifying boundaries and defining interfaces. This process groups related code files into cohesive components and visualizes their interactions using Mermaid syntax within a container.

What is the best way to group code files into logical components for software design?

The best way to group code files into logical components for software design is to systematically analyze code-level documentation. This identifies component boundaries and defines APIs, protocols, and data contracts, bridging the gap between detailed code and higher-level architectural views.

How does component synthesis work for defining interfaces in C4 architecture?

Component synthesis for defining interfaces in C4 architecture works by analyzing code-level elements and grouping them into logical components. It documents component APIs, protocols, and data contracts to clearly define how synthesized components interact within a container.

Do I need existing code-level documentation to create C4 component architecture?

Yes, you need existing code-level documentation to create C4 component architecture. The synthesis process requires systematic analysis of these detailed files to identify component boundaries, define interfaces, and generate accurate component-level diagrams.

Can I use Mermaid syntax to visualize component relationships within a container?

Yes, you can use Mermaid syntax to visualize component relationships within a container. The component synthesis process generates C4 Component-level diagrams using Mermaid syntax, mapping out the interactions and interfaces between grouped logical components.

When should I synthesize code into C4 components instead of documenting individual files?

You should synthesize code into C4 components when you need to bridge detailed code-level documentation with higher-level architectural views. This approach groups individual files into cohesive components like UserService, providing a broader understanding of system architecture.
