ROUTING SKILL — delegates to specialized diagram skills. USE FOR: any diagram request when the caller does not know which tool to use. Routes to drawio, python-diagrams, or mermaid based on diagram type.
Mermaid diagram generation for inline markdown documentation: flowcharts, sequence diagrams, Gantt charts, class diagrams, state diagrams, ER diagrams, and architecture visualizations. USE FOR: inline markdown diagrams, flowcharts, sequence diagrams, Gantt charts, state diagrams, ER diagrams, Azure resource visualization. DO NOT USE FOR: architecture diagrams with Azure icons (use drawio), WAF/cost charts (use python-diagrams), Draw.io diagrams (use drawio).
Python diagram generation: WAF/cost/compliance charts (matplotlib), architecture diagrams (diagrams library), ERDs, swimlanes, timelines, wireframes (graphviz). USE FOR: WAF bar charts, cost donut/projection charts, compliance gap charts, Python architecture diagrams, ERD diagrams, business process flows, timeline/Gantt charts, UI wireframes. DO NOT USE FOR: Draw.io architecture diagrams (use drawio), inline Mermaid (use mermaid), Excalidraw whiteboarding (use excalidraw).
Generate or edit images using Google Nano Banana (Gemini image generation API). Trigger this skill whenever the user asks to generate an image, draw something, create artwork, edit a photo, or mentions "nano banana", "nanobanana", or any AI image generation/editing need — even if they don't explicitly mention Nano Banana. Proactively use this skill for any image creation or transformation request.
