diagram-generator
Generate a diagram and route to the right engine — draw.io XML (precise, editable, C4, swimlanes) or Excalidraw JSON (hand-drawn, sketch, wireframes). One entry for flowcharts, architecture, ER, sequence, mind maps. Don't use for Mermaid or slides.

What this skill does
Diagram Generator Single entry point for "make me a diagram". This umbrella picks the right engine and hands off to it — both produce the same diagram taxonomy (flowchart, architecture, C4, ER, sequence, mind map) through the same four phases (Understand → Propose → Generate → Validate); they differ only in output format and aesthetic. Which engine? Pick When the user wants... Output Nested skill --- --- --- --- draw.io Precise, professional diagrams to edit later in draw.io / diagrams.net / Confluence; official C4 styling; swimlanes; multi-page .drawio XML drawio-generator Excalidraw A hand-drawn, sketchy, whiteboard feel; wireframes; quick collaborative sketches .excalidraw JSON excalidraw-generator Routing rules: The user names a format or tool ("draw.io", "diagrams.net", "Excalidraw", "whiteboard sketch") → use that engine. The user names an editing target ("I'll tweak it in draw.io", "import to Confluence") → draw.io. The user wants a hand-drawn / sketch / wireframe look → Excalidraw. No format signal → ask one question: "Precise and editable (draw.io) or hand-drawn sketch (Excalidraw)?" Keep routing blocked until the user answers. Only after explicit delegation such as "just pick", "choose for me", or "use the default", choose draw.io for architecture/C4/technical diagrams and Excalidraw for wireframes/brainstorms. The user asks for Mermaid, a slide deck, or brand/marketing graphics → out of scope; say so (Mermaid is native markdown; use a presentation or design tool for the others). How to use Once the engine is chosen, invoke the nested skill by name — the runtime resolves names regardless of filesystem path: /drawio-generator — generate draw.io XML /excalidraw-generator — generate Excalidraw JSON Each engine owns its full workflow, references/, agents/, and validation checks. This umbrella stays short to protect the agent's context budget; it only routes. Prerequisites 1. Confirm at least one nested engine is installed and callable. 2. …
