SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Converting complex system designs, flows, and data models into clear, versionable, and shareable diagrams can be time-consuming and error-prone when done by hand; this Skill provides concise guidance and patterns to create accurate diagrams from plain-text definitions using Mermaid syntax.

Core Features & Use Cases

  • Supports a broad set of diagram types: class diagrams, sequence diagrams, flowcharts, ERDs, C4 architecture diagrams, state diagrams, git graphs, Gantt charts, and basic charts for metrics.
  • Covers theming, styling, layout options (dagre/ELK), subgraphs, notes, conditional blocks, and export workflows for Markdown, CLI, and live editors.
  • Use Case: Document an API authentication flow for frontend engineers using a sequence diagram, or model database schema changes as ERDs that live alongside your code in version control.

Quick Start

Generate a sequence diagram that shows an authentication flow between User, API, and Database.

Frequently Asked Questions about mermaid-diagrams

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

FAQPage Schema
How do I create software architecture diagrams from plain text for Markdown documentation?

You can generate software architecture diagrams from plain text by writing Mermaid syntax definitions. This approach produces versionable, shareable diagrams suitable for Markdown rendering, live preview, and CLI export.

What types of diagrams can I generate using Mermaid syntax?

Mermaid syntax supports a broad set of diagrams including sequence diagrams, flowcharts, ERDs, class diagrams, C4 architecture models, state diagrams, git graphs, and Gantt charts for documentation and design reviews.

Can I style and theme flowcharts generated from text definitions?

Yes, you can apply theming, styling, and layout options like dagre or ELK to flowcharts generated from text definitions. You can also use subgraphs, notes, and conditional blocks to customize the visualization output.

How do I model an API authentication flow as a sequence diagram?

To model an API authentication flow as a sequence diagram, define the interactions between participants like User, API, and Database using Mermaid sequence diagram syntax to visualize the step-by-step message exchanges.

What is the best way to visualize database schema changes alongside my code?

The best way to visualize database schema changes alongside code is to model them as ERDs using Mermaid syntax. This allows the diagrams to live directly in version control as plain-text definitions.

Why use text-based diagrams instead of manual diagram editors for design reviews?

Text-based diagrams avoid the time-consuming and error-prone nature of manual editing. Using plain-text Mermaid definitions ensures diagrams remain versionable, easily updatable, and shareable across design reviews and onboarding.
