# 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`:

```bash
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:
```
MEDIA:/tmp/qr_c9e87fb7.png
```

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:
