SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps you turn a vague architecture discussion into clear, audience-appropriate C4 diagrams so stakeholders can quickly understand system scope, containers, components, and deployments.

Core Features & Use Cases

  • Generates C4 diagrams in Mermaid for common architecture visualization needs, including context, container, component, deployment, and dynamic request flows.
  • Selects the right abstraction level (C4 level 1–4) based on audience needs like executives (context) or developers (context + key components).
  • Produces maintainable documentation output by writing diagram content with explanatory context (including suggested output locations and diagram naming conventions).

Use cases: Create a system context diagram for a new product, document a microservice container diagram for onboarding, generate a deployment view for DevOps planning, or illustrate an authentication/payment flow using a dynamic (request) diagram.

Quick Start

Ask for a C4 context and container diagram for your system, specifying the system name and target audience.

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 architecture diagrams in Mermaid from my codebase?▼

To generate C4 architecture diagrams in Mermaid, specify your system name and audience. The Skill selects the appropriate C4 level and outputs system context, container, component, deployment, or dynamic request-flow diagrams in Mermaid syntax.

What is the C4 model and when do I need a system context diagram?▼

The C4 model is a technique for visualizing software architecture at four abstraction levels. You need a system context diagram to show high-level scope for executives, while developers use container and component diagrams for onboarding and reviews.

Can I use this to create deployment diagrams and dynamic request flow illustrations for DevOps planning?▼

Yes, you can create deployment diagrams and dynamic request flow illustrations for DevOps planning. The Skill generates these specific C4 views in Mermaid syntax to help stakeholders understand infrastructure and authentication or payment flows.

What's the best way to document microservices for onboarding using container diagrams?▼

The best way to document microservices for onboarding is generating a C4 container diagram. The Skill enforces C4 modeling rules, adding element names, types, labels, and descriptions to produce well-structured Mermaid output for technical reviews.

Does this approach support selecting different C4 levels for different audiences?▼

Yes, the approach supports selecting different C4 levels for different audiences. It automatically selects the right abstraction level, generating context diagrams for executives and component-level diagrams for developers based on your specified audience.
