Draw.io Professional Diagrams

What this skill does

Generate professional draw.io diagrams (ERD/database tables, class diagrams, sequence diagrams, flowcharts, architecture diagrams) and export them as PNG.

Draw.io Professional Diagrams is part of the Data & APIs category — data and API skills that fetch, query, and work with external data sources. You can install it on its own or alongside other data & apis skills from the OpenClaw catalog.

How to install Draw.io Professional Diagrams

The easiest path is via the OpenClaw Easy desktop app — one click, no terminal required:

1. Download OpenClaw Easy for macOS or Windows (free, one-click installer, ~30 seconds).
2. Open the in-app Skills panel.
3. Search for drawio and click Install.
4. The skill activates automatically when an incoming message matches its description.

Install from the command line

If you already run the OpenClaw CLI, add Draw.io Professional Diagrams with a single command:

openclaw skills add drawio

This pulls drawio from ClawHub and installs it into ~/.openclaw/skills/drawio/. Restart the OpenClaw gateway afterwards so the new skill is discovered.

How to use Draw.io Professional Diagrams

Once installed, Draw.io Professional Diagrams 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

Draw.io Professional Diagrams 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.

Manual install (advanced)

If you prefer manual installation:

1. Click the Download .zip button above to grab drawio-1.0.0.zip directly from our S3 mirror.
2. Unzip into ~/.openclaw/skills/drawio/ (create the directory if it does not exist).
3. Restart OpenClaw Easy (or the OpenClaw CLI gateway) so the new skill is discovered.
