Mermaid Diagram Library

About

The Mermaid Diagram Library is an enterprise-grade toolkit for Claude Code designed to streamline the creation of visual technical documentation. It supports a comprehensive suite of 21 diagram types, including flowcharts, sequence diagrams, C4 architecture models, and Gantt charts. By integrating with the Playwright MCP server, it enables seamless rendering of diagrams into SVG or PNG formats directly within the development workflow. This skill is ideal for architects and developers who need to visualize complex system flows, manage state machines, or document data structures with precision and consistency.
