1ExcalidrawExcalidraw is an agent skill that wraps the `excalidraw` CLI so Claude Code, Cursor, Codex, and similar agents can operate a running Excalidraw canvas programmatically. Solo and indie builders use it when they want diagrams that stay in sync with conversation—system maps, onboarding flows, API sketches, and whiteboard layouts—without switching context to a separate drawing app for every edit. The skill covers element CRUD, batch JSON layouts, canvas describe and screenshot, file exchange, snapshot restore, layout helpers, Mermaid conversion, and shareable excalidraw.com links. It explicitly routes richer visual work through companion skills for workflow planning and design rules. You need a healthy canvas server before drawing; trivial one-shot commands can skip companions, while mindmaps and quality-sensitive visuals should load both workflow and design guides. It fits builders who document as they build and want verified, incremental diagram updates rather than static screenshots from chat.1installs
