SYSTEM DOCUMENTATION & REQUIREMENTS

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

What problem does it solve?

This Skill converts text descriptions into high-quality Mermaid diagrams, streamlining the creation of diagrams for technical documentation and presentations.

Core Features & Use Cases

  • Mermaid Diagram Generation: Converts user text into flowcharts, sequence diagrams, class diagrams, ER diagrams, Gantt charts, and more.
  • Syntax Verification: Ensures the correctness of the generated diagrams through Mermaid CLI verification.
  • File Output: Saves .mmd and .md files with the diagram code and embedded Markdown preview to the 'figures/' directory.
  • Use Case: A software developer wants to create a flowchart of the software architecture. They use this Skill to describe the flowchart and generate the diagram, which is then saved for inclusion in documentation.

Quick Start

Generate a flowchart describing the software architecture by providing the description of the flowchart to the mermaid-diagram skill.

Frequently Asked Questions about mermaid-diagram

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

FAQPage Schema
How do I generate Mermaid diagrams from text descriptions for technical documentation?▼

To generate Mermaid diagrams from text, provide a text description of your flowchart or sequence diagram. The system converts the input into Mermaid syntax, verifies it, and outputs .mmd and .md files to the 'figures/' directory.

What types of diagrams can I create using text-based diagramming for software architecture?▼

Text-based diagramming supports flowcharts, sequence diagrams, class diagrams, ER diagrams, and Gantt charts. This covers standard software architecture and technical documentation needs without requiring manual drawing tools.

Do I need the Mermaid CLI installed to render text into flowcharts and sequence diagrams?▼

Yes, the Mermaid CLI is required. This dependency performs syntax verification on the generated diagram code to ensure the output flowcharts and sequence diagrams render correctly before saving the files.

How does syntax verification work when converting text to Mermaid diagrams?▼

Syntax verification uses the Mermaid CLI to validate the generated diagram code during conversion. This ensures the text-to-diagram output is syntactically correct, preventing rendering errors in your technical documentation.

What is the best way to include generated diagrams into Markdown documentation?▼

The best way to include generated diagrams is through the automatic Markdown output. The system saves an .md file with an embedded preview alongside the .mmd source code, ready for immediate inclusion in your documentation.

What file formats are output when creating ER diagrams and Gantt charts from text?▼

When creating ER diagrams and Gantt charts, the output consists of .mmd files containing the raw Mermaid code and .md files with an embedded Markdown preview. Both are saved directly to a 'figures/' directory.
