How to install Excalidraw Diagram Generator

- Download OpenClaw Easy for macOS or Windows (free, one-click installer, ~30 seconds).
- Open the in-app Skills panel.
- Search for
excalidrawand click Install. - The skill activates automatically when an incoming message matches its description.
Install from the command line
If you already run the OpenClaw CLI, add Excalidraw Diagram Generator with a single command:
openclaw skills add excalidraw
This pulls excalidraw from ClawHub and installs it into ~/.openclaw/skills/excalidraw/. Restart the OpenClaw gateway afterwards so the new skill is discovered.
How to use Excalidraw Diagram Generator
Once installed, Excalidraw Diagram Generator activates on its own: when an incoming message on WhatsApp, Telegram, Slack, Discord, Feishu or Line matches the skill's description, your OpenClaw agent loads it and runs the workflow. You can also trigger it explicitly by describing the task in chat. No extra configuration is required after install.
Turning images into video
Excalidraw Diagram Generator works with images. Getting from there to something postable is a separate job: ViralMint — an open-source video pipeline — turns stills into motion — pans and transitions, synced captions, and a vertical export for short-form feeds.
It runs as an MCP server, so an OpenClaw agent can drive it from the same chat you already use: ask for a short, and the render comes back finished. See how to connect a video pipeline to your agent.
