What problem does it solve?

Configuring Mermaid diagrams in Claude plugins can be verbose and error-prone, especially when switching themes, output formats, or validating dependencies across projects.

Core Features & Use Cases

  • Configure Mermaid theme, output directory, and rendering options from a single JSON config (.claude/mermaid.json).
  • Health-check workflow to verify Node.js presence, install missing dependencies, and perform a render smoke test to ensure rendering works in CI or local environments.
  • Use Case: A developer wants to switch diagrams to a dark theme and ensure diagrams render to SVG across all projects with a single command.

Quick Start

Run the mermaid-config skill to view or update settings or perform a health check.

FAQPage Schema
How do I configure Mermaid themes and output formats for Claude plugins?

You can configure Mermaid rendering options by updating the .claude/mermaid.json file to set themes, output directories, and output formats like SVG across multiple project environments.

How do I run a health check for Mermaid rendering dependencies?

You can run a health-check workflow to verify Node.js presence, install missing dependencies, and perform a render smoke test to ensure diagrams render correctly in CI or local environments.

Do I need Node.js to render Mermaid diagrams in CI environments?

Yes, Node.js is required to render Mermaid diagrams. The health-check workflow specifically verifies Node.js presence and installs missing dependencies before performing a render smoke test.

What is the best way to switch Mermaid diagrams to a dark theme across multiple projects?

The best way to switch Mermaid diagrams to a dark theme across projects is to update the theme setting in the .claude/mermaid.json configuration file, applying the rendering change universally.

Why is my Mermaid plugin configuration not working across different environments?

Mermaid plugin configuration may fail if the .claude/mermaid.json file is misconfigured or if dependencies are missing, which you can diagnose using the health-check render smoke test.
