What diagram types does this skill support?

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

Can I use the output directly in my documentation?

Yes, the skill generates standard Mermaid syntax that can be embedded directly into markdown files supported by GitHub, GitLab, Obsidian, and Notion.

Do I need to provide code to generate a diagram?

No, you can provide plain text descriptions, module specifications, or high-level workflow summaries, and the skill will extract the logic to build the visual.

How does it handle complex system architectures?

It follows a structured extraction process to identify key nodes and relationships, ensuring the resulting diagram is organized, readable, and follows visual conventions.

Is this skill specific to a certain programming language?

No, it is language-agnostic and works for any system design, database schema, or project management timeline regardless of the technology stack.

Learning & Documentation

Converts complex system architectures, module specifications, and workflows into production-ready Mermaid diagrams for markdown documentation.

About

This skill empowers developers and architects to bridge the gap between technical text and visual communication by automatically generating valid Mermaid syntax. By analyzing architectural descriptions, module contracts, or agentic workflows, it produces structured visualizations including flowcharts, sequence diagrams, and entity-relationship models. It is particularly effective for documenting module relationships, mapping state machine transitions, and visualizing multi-agent interactions within Claude Code environments, ensuring that documentation remains visual, accurate, and easily embeddable in standard markdown files.
