excalidraw-render

@isala404

Generate clean, production-quality Excalidraw architecture diagrams from any input — ASCII sketches, vague descriptions, component lists, screenshots, or rough mockups. Use this skill whenever the user asks for an architecture diagram, system diagram, data flow, sequence diagram, call chain, or any visual diagram, even when they just say "draw me X" or paste rough ASCII art. The skill writes a .excalidraw JSON file, renders it locally to PNG via @swiftlysingh/excalidraw-cli, and iterates by viewing the rendered image until layout, alignment, spacing, and labels are correct. Heavy use of Haiku sub-agents for all JSON authoring and edits keeps token costs low — the main agent only critiques rendered images, never reads or edits the raw JSON.
