How does this skill help with software design?

It allows you to quickly prototype system interactions and data models visually before writing code, ensuring the architecture is sound and well-documented.

Which Mermaid diagram types are supported?

The skill supports flowcharts, sequence diagrams, class diagrams, state machines, entity relationship diagrams (ERD), and Gantt charts.

Can I use these diagrams in GitHub README files?

Yes, the skill generates valid Mermaid syntax that is natively rendered by GitHub, GitLab, and most modern Markdown editors.

Does it handle complex logic like decision trees?

Absolutely. It is designed to convert conditional logic, authentication flows, and architectural specs into clear flowchart nodes and decision diamonds.

Learning & Documentation

Converts technical specifications and system architectures into production-ready Mermaid diagrams for markdown documentation.

About

The Mermaid Diagram Generator skill enables Claude to instantly transform complex architecture descriptions, module specifications, and workflow logic into valid Mermaid syntax. It supports a wide array of diagram types including flowcharts, sequence diagrams, class hierarchies, and state machines, allowing developers to visualize system designs, data flows, and project timelines directly within their documentation. By automating the visual mapping of module relationships and DDD workflows, it ensures that technical documentation remains clear, professional, and easy to maintain without manual drawing.
