Mermaid Expert
Creates clear, professional Mermaid diagrams - flowcharts, sequence diagrams, ERDs, state diagrams, Gantt charts, and architecture diagrams - always delivering both a basic and styled version with rendering instructions. Use when a process, data model, timeline, or architecture needs to be visualized as a Mermaid diagram.
What it does
Acts as a Mermaid diagram expert specializing in clear, professional visualizations across flowcharts, sequence diagrams, ERDs, state diagrams, Gantt charts, and architecture/network diagrams.
When to use - and when NOT to
Use this skill when working on Mermaid expert tasks or workflows that need guidance, best practices, or checklists. Do not use it for tasks unrelated to Mermaid diagrams, or when a different domain or tool is actually needed.
Inputs and outputs
Focus areas: flowcharts and decision trees, sequence diagrams for APIs and interactions, Entity Relationship Diagrams (ERD), state diagrams and user journeys, Gantt charts for project timelines, and architecture/network diagrams.
Diagram types covered: graph (flowchart), sequenceDiagram, classDiagram, stateDiagram-v2, erDiagram, gantt, pie, gitGraph, journey, quadrantChart, and timeline.
Approach: choose the diagram type that actually fits the data rather than defaulting to one, keep diagrams readable by avoiding overcrowding, use consistent styling and colors throughout, add meaningful labels and descriptions rather than terse placeholders, and test that the diagram actually renders before delivering it.
Output produced for each request: complete Mermaid diagram code, rendering instructions or a preview, alternative diagram type options where more than one fits the data, styling customizations, accessibility considerations, and export recommendations. Both a basic version and a styled version are always provided together, and comments explain any complex syntax so the diagram code remains maintainable by someone other than its original author.
Integrations
Outputs standard Mermaid syntax, which renders directly in any Mermaid-compatible environment - GitHub/GitLab markdown, documentation sites, Notion, and dedicated Mermaid live editors - without requiring a separate diagramming tool or image export step for basic use.
Who it's for
Anyone who needs to communicate a process, data model, timeline, or system architecture visually via Mermaid - choosing the right diagram type for the data, keeping it readable, and getting both a plain and a styled version ready to render, with comments explaining any syntax that isn't immediately obvious to a future reader.
