# Mermaid and Excalidraw rendering Use inline Mermaid when it serves the conversation. For exported assets, preserve the input format and requested visual style. Resolve actual CLI/browser capabilities; do not assume Claude/BYOB tools or DOM evaluation are available. ## Excalidraw input and hand-drawn exports For an existing `.excalidraw` file, inspect its JSON and confirm it has scene elements. Use the installed `excalidraw-export` CLI after checking `--help`. Its PNG workflow is: ```sh excalidraw-export input.excalidraw -o output.png --scale 2 ``` If absent, check the documented `@moona3k/excalidraw-export` package or use the available Excalidraw UI export. Do not silently substitute a conventional Mermaid render when the user wants the hand-drawn style. For Mermaid-to-hand-drawn output, use Excalidraw's Mermaid import through the available browser surface. Start a fresh scene so unrelated canvas content is preserved. Read the `.mmd`, import its source, inspect the inserted scene, and export PNG/SVG or save the editable `.excalidraw` scene through the observed UI. A supported scene-export API is also suitable. Do not depend on undocumented localStorage access or assume browser tools permit reading it. If no export path works, retain the source and report the missing capability instead of claiming a finished asset. ## Conventional Mermaid output For ordinary Mermaid SVG/PNG, resolve an installed renderer such as `mmdc`, inspect its help, and render the `.mmd` at suit
