User Flow Diagram Skill

Purpose

Generate user flow diagrams, flowcharts, and navigation maps to visualize user journeys and application flows.

Capabilities

• Create Mermaid.js flow diagrams
• Generate flowcharts from user journeys
• Export to SVG, PNG, and other formats
• Validate flow completeness
• Identify dead ends and loops
• Generate sitemap visualizations

Target Processes

• wireframing.js
• user-journey-mapping.js
• information-architecture.js

Integration Points

• Mermaid.js for diagram generation
• diagrams.net API for export
• PlantUML for alternative syntax
