QR Code Generator 📱

Creates high-redundancy, branded QR codes with the Haumdaucher logo centered on a clean white background.

When to Use

• Whenever you share a link (https://...), website, recipe, document, Wi-Fi configuration, or arbitrary text and want to offer a scannable QR code.
• Whenever the user accepts an ask_user prompt to generate a QR code for a hosted artifact.
• Whenever the user explicitly asks for a QR code ("Erstelle einen QR-Code für ...").

Execution

Run the bundled Python script via uv run:

uv run /home/node/mop-skills/mop-skills/skills/qr-code/scripts/generate_qr.py "<URL-or-Text>"

Script Arguments:

• <text>: The URL or string to encode (mandatory).
• --output <path>: Optional target file path (defaults to /tmp/qr_<hash>.png).
• --logo <path>: Optional custom logo PNG (defaults to bundled Haumdaucher logo).

Output & Telegram Delivery

The script outputs:

When returning your reply to the user, include the MEDIA:<path> line at the very beginning or end of your message. OpenClaw's Telegram integration will automatically upload the image directly into the chat:
