SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill eliminates the manual effort of drawing architecture diagrams by automatically analyzing your project's structure and generating visual representations, ensuring your documentation stays in sync with your code.

Core Features & Use Cases

  • Automated C4 Generation: Creates System Context, Container, and Component diagrams directly from your source code.
  • Flexible Output: Supports both Mermaid code for documentation and direct integration with IcePanel for professional modeling.
  • Use Case: When onboarding a new developer to a complex monorepo, use this Skill to generate a clear C4Container diagram of the services, helping them visualize the system boundaries and data flow in seconds.

Quick Start

Use the diagramming-architecture skill to generate a full system diagram for the current project directory.

Frequently Asked Questions about diagramming-architecture

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automatically generate C4 architecture diagrams from my codebase?▼

You can generate C4 architecture diagrams by analyzing your project directory structure to produce System Context, Container, and Component diagrams directly from your source code. This eliminates manual drawing and keeps documentation synced with your code.

Can I output Mermaid syntax for documentation or do I need IcePanel?▼

You can output Mermaid syntax for documentation or integrate directly with the IcePanel REST API for professional modeling. Mermaid requires Node.js for rendering, while IcePanel requires its MCP server connectivity.

Do I need Python and Node.js to generate architecture diagrams from source code?▼

Python 3.10+ is required for codebase analysis. Node.js is optional and only needed if you want to render Mermaid diagrams or connect to the IcePanel MCP server.

How do I scope architecture diagrams for specific subdirectories in a monorepo?▼

You can scope architecture generation for monorepo subdirectories by analyzing specific project paths. This allows topic-focused business process tracing across multiple modules to visualize system boundaries and data flow.

What is the best way to visualize system boundaries for new developer onboarding?▼

Generating a C4 Container diagram from your project directory helps new developers visualize system boundaries and data flow in seconds. It automatically analyzes services to create clear visual representations without manual effort.

What are the limitations of automated codebase architecture diagram generation?▼

Automated architecture diagram generation relies on analyzing project directory structures rather than runtime behavior. It requires Python 3.10+ and cannot capture dynamic data flow or undocumented external dependencies not reflected in the codebase.
