To generate C4 model architecture diagrams automatically, this Skill analyzes BRIEF.md, DOMAIN-MODEL.md, and ADR files to produce Mermaid syntax diagrams for Level 1 System Context and Level 2 Container views in a SYSTEM-DESIGN.md document.

Creating a System Context diagram from markdown requirements involves parsing textual documents like BRIEF.md and ADR files to map system boundaries and data flows, which this Skill automates using Mermaid syntax.

To document system containers and data flows in Mermaid, the Skill extracts architectural components from your domain model and ADRs, generating Level 2 Container diagrams that visually represent the internal structure and interactions.

Yes, ADR files are required alongside BRIEF.md and DOMAIN-MODEL.md to generate the SYSTEM-DESIGN.md document, as the Skill relies on these inputs to accurately map system boundaries, containers, and data flows for the C4 diagrams.

No, you cannot use this to generate Level 3 Component diagrams. The Skill specifically automates C4 model diagram generation for Level 1 System Context and Level 2 Container views using Mermaid syntax.

Using the C4 model over other architecture diagram formats provides structured hierarchical visualization—System Context and Container levels—that transforms textual requirements into clear visual blueprints, improving communication and architectural consistency.
