SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @mermaid-js/mermaid-cli, and includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

Manual diagram creation is slow, inconsistent, and often out-of-sync with evolving code. Creating comprehensive design documents from scratch is time-consuming and prone to outdated information. This Skill automates the generation of accurate, high-contrast, and semantically rich Mermaid diagrams and complete design documents, ensuring consistency, accessibility, and saving significant time by keeping your documentation synchronized with your codebase.

Core Features & Use Cases

  • Intelligent Diagram Generation: Create activity, deployment, architecture, and sequence diagrams on demand using a hierarchical, token-efficient system. Automatically applies high-contrast styling and Unicode semantic symbols for clarity and accessibility.
  • Code-to-Diagram Conversion: Generate architecture and deployment diagrams directly from source code (e.g., Spring Boot, FastAPI, Node.js) and configuration files, ensuring your visual documentation reflects the current state of your codebase.
  • Comprehensive Design Documents: Automatically generate full API, architecture, feature, database, or system design documents with embedded, consistent diagrams, drastically reducing manual writing effort.
  • Use Case: Need an up-to-date deployment diagram for your Spring Boot microservice running on GCP? Simply provide your application.yml content, and the Skill will generate a detailed, accessible diagram, saving you hours of manual mapping and drawing.

Quick Start

Create an activity diagram for the user login flow with email verification steps.

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

Generate architecture diagrams directly from source code and configuration files by providing your codebase content, and the Skill converts it into Mermaid diagrams that reflect your current system state, eliminating manual mapping and keeping documentation synchronized.

Can I create design documents with embedded diagrams from code?▼

Yes, the Skill automatically generates comprehensive API, architecture, feature, and database design documents with embedded Mermaid diagrams, reducing manual writing effort by extracting information directly from your codebase and configurations.

What diagram types can I generate for my system?▼

You can generate activity, deployment, architecture, and sequence diagrams on demand, each with high-contrast styling and Unicode semantic symbols for accessibility and clarity across different system documentation needs.

Does this work with Spring Boot and YAML configuration files?▼

Yes, the Skill extracts configuration from Spring Boot, YAML, and other sources, converting them into detailed deployment and architecture diagrams that visualize your infrastructure and service dependencies.

How do I ensure my diagrams stay synchronized with code changes?▼

By generating diagrams on demand from your current codebase and configuration files, the Skill automatically reflects code changes without manual updates, keeping your technical documentation always aligned with implementation.

What makes these diagrams more accessible than manually drawn ones?▼

The Skill applies high-contrast styling by default and uses Unicode semantic symbols, ensuring diagrams meet accessibility standards and are readable across different contexts and assistive technologies.
