SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Mermaid-diagrams provide a ready-to-use, self-contained knowledge package that lets agents generate accurate diagrams without hand-constructing prompts or hunting for examples.

Core Features & Use Cases

  • Supports multiple Mermaid diagram types (class, sequence, flowchart, ERD, C4, state, git graph, Gantt, and more) with example-driven guidance.
  • Bundles on-demand references and templates to speed up architecture documentation and design reviews.
  • Frontmatter-driven configuration and theming to keep visuals consistent with brand or project style.

Quick Start

Write a small Mermaid diagram snippet in your documents or activate the skill with a request describing the diagram you need.

Frequently Asked Questions about mermaid-diagrams

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

FAQPage Schema
How do I generate Mermaid flowcharts and sequence diagrams from existing code?▼

To generate Mermaid diagrams from code, describe the software architecture or provide the code structure, and the skill translates it into flowcharts, sequence diagrams, or ERDs with validation for correctness.

What's the best way to visualize software architecture for documentation?▼

Visualizing software architecture is best handled by translating requirements and code structure into Mermaid diagrams, supporting class, C4, state machine, and ERD diagrams with frontmatter-driven theming for consistent documentation.

Can I apply custom themes and configuration to Mermaid diagrams?▼

Yes, you can apply custom themes to Mermaid diagrams using frontmatter-driven configuration, ensuring visuals remain consistent with your brand or project style guidelines across architecture documentation.

Does this approach support generating ERDs and C4 diagrams for real-world projects?▼

Generating ERDs and C4 diagrams is fully supported for real-world projects, applying example-driven guidance and a validation loop to enforce diagram correctness while handling errors gracefully across multiple Mermaid types.

Why do my auto-generated architecture diagrams contain syntax errors?▼

Architecture diagrams contain syntax errors when Mermaid syntax rules are violated, but this skill enforces correctness through a validation loop and handles errors gracefully to prevent invalid diagram outputs.
