SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

C4 architectural modeling helps teams consistently visualize software architecture from context to code using Mermaid diagrams, improving communication and planning across stakeholders.

Core Features & Use Cases

Four abstraction levels (Context, Container, Component, Code) captured in Mermaid diagrams.
Level-guided workflows and best-practice guidelines to avoid mixing levels.
Templates and syntax references for Mermaid C4 diagrams to support documentation and architecture reviews.

Quick Start

Provide a system overview to generate a Level 1 C4 diagram in Mermaid.

FAQPage Schema

How do I create C4 diagrams using Mermaid syntax?▼

To create C4 diagrams using Mermaid syntax, you provide a system overview to generate visualizations across context, container, component, and code abstraction levels. The Skill automates diagram generation while enforcing level discipline and technology annotations.

What is the best way to document software architecture from context to code?▼

Documenting software architecture from context to code is best done using the C4 model, which breaks down system boundaries into four abstraction levels. This approach improves stakeholder communication and planning by keeping visualizations consistently structured.

Can I use C4 model diagrams for stakeholder communication and architecture planning?▼

Yes, C4 model diagrams are explicitly designed for stakeholder communication and architecture planning. By separating context, container, component, and code boundaries, they provide clear visualizations tailored to different audience needs.

How do I avoid mixing abstraction levels when generating C4 architecture diagrams?▼

To avoid mixing abstraction levels when generating C4 architecture diagrams, apply level-guided workflows and best-practice guidelines. The Skill enforces level discipline, proper labeling, and technology annotations to maintain strict boundaries between context, container, component, and code.

Does Mermaid syntax support all four C4 architecture levels?▼

Yes, Mermaid syntax supports all four C4 architecture levels. The Skill uses templates and syntax references specifically for Mermaid C4 diagrams to capture context, container, component, and code abstractions for documentation and reviews.

What input do I need to generate a Level 1 C4 context diagram?▼

To generate a Level 1 C4 context diagram, you need to provide a system overview. The Skill then processes this input to output a Mermaid diagram visualization that maps the system and its external dependencies.
