What problem does it solve?
Converting complex system designs, flows, and data models into clear, versionable, and shareable diagrams can be time-consuming and error-prone when done by hand; this Skill provides concise guidance and patterns to create accurate diagrams from plain-text definitions using Mermaid syntax.
Core Features & Use Cases
- Supports a broad set of diagram types: class diagrams, sequence diagrams, flowcharts, ERDs, C4 architecture diagrams, state diagrams, git graphs, Gantt charts, and basic charts for metrics.
- Covers theming, styling, layout options (dagre/ELK), subgraphs, notes, conditional blocks, and export workflows for Markdown, CLI, and live editors.
- Use Case: Document an API authentication flow for frontend engineers using a sequence diagram, or model database schema changes as ERDs that live alongside your code in version control.
Quick Start
Generate a sequence diagram that shows an authentication flow between User, API, and Database.
