SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

Mermaid diagram creation often requires manual iteration and formatting; this skill automates generating Mermaid .mmd files, validating syntax, and exporting to PNG/SVG/PDF.

Core Features & Use Cases

  • Generate Mermaid diagrams from natural language prompts.
  • Validate syntax before export to catch errors early.
  • Export to PNG/SVG/PDF using local mmdc or Kroki API.
  • Support 11+ diagram types including flowchart, sequence, class, ER, state, Gantt, Git Graph, C4, and mind map.
  • Use cases: architecture diagrams, API flows, data model visualizations, CI/CD pipelines.

Quick Start

Describe a diagram you want in Claude Code and it will generate the .mmd file, validate it, and export the diagram.

Frequently Asked Questions about creating-mermaid-diagrams

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

FAQPage Schema
How do I generate Mermaid diagrams from plain text and export them as images?▼

To generate Mermaid diagrams from plain text, you provide a natural language prompt and the tool outputs a .mmd file, validates the syntax, and exports it as PNG, SVG, or PDF.

What diagram types are supported for architecture and data model visualization?▼

Supported diagram types include 11+ formats such as flowchart, sequence, class, ER, state, Gantt, Git Graph, C4, and mind map for architecture and data model visualization.

Do I need a local mmdc installation or Kroki API to export Mermaid files?▼

You need either a local mmdc installation or the Kroki API to export Mermaid files, as the tool requires one of these environments to render and export diagrams to PNG, SVG, or PDF.

How does syntax validation work before exporting a Mermaid diagram?▼

Syntax validation works by enforcing a validation-first workflow that checks the generated .mmd file for errors before attempting to export the diagram, ensuring reliable outputs without rendering failures.

Can I automate creating CI/CD pipeline and API sequence flow diagrams in Mermaid?▼

You can automate creating CI/CD pipeline and API sequence flow diagrams in Mermaid by providing natural language prompts, which the tool converts into validated .mmd files and exports automatically.

Why does my Mermaid diagram export fail when using natural language generation?▼

Mermaid diagram exports fail when syntax errors exist in the generated .mmd file; enforcing a validation-first workflow before exporting catches these errors early to prevent rendering failures.
