About This Skill
What it does
The c4-architecture skill enables AI agents to analyze and model software architecture using the C4 model, which includes Context, Containers, Components, and Code levels. It helps users visualize system structures, identify dependencies, and generate architectural diagrams or documentation based on input requirements.
When to use it
- When designing a new software system and needing to document its structure at multiple abstraction levels.
- When reviewing an existing architecture for clarity or scalability improvements.
- During team collaboration sessions to align stakeholders on the technical vision of a project.
- When preparing architectural documentation for audits, presentations, or handovers.
Key capabilities
- Generates C4 model diagrams (Context, Containers, Components, Code).
- Parses natural language descriptions into structured architecture models.
- Supports export of architecture models in common formats like UML or JSON.
- Integrates with codebases to extract component-level details automatically.
Example prompts
- "Create a C4 architecture diagram for a microservices-based e-commerce platform."
- "Generate the Context and Containers level of the system described in this document."
- "Export the Component model of our current application as a JSON file."
Tips & gotchas
- Ensure input descriptions are clear and detailed to get accurate architectural outputs.
- This skill works best with systems that have well-defined boundaries and modular components.
