How to install the code-to-diagram skill

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 code-to-diagram 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 the code-to-diagram skill with a single command:

openclaw skills add code-to-diagram

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

How to use the code-to-diagram skill

Once installed, the code-to-diagram skill 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

code-to-diagram 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 skill .zip button above to grab code-to-diagram-3.0.0.zip directly from our S3 mirror.
2. Unzip into ~/.openclaw/skills/code-to-diagram/ (create the directory if it does not exist).
3. Restart OpenClaw Easy (or the OpenClaw CLI gateway) so the new skill is discovered.
