# QR Code Generator

Turn links, text, contact details or WiFi credentials into a QR code image.
Generated offline — nothing is sent anywhere.

## What it does

- **Link / text codes**: any content to a PNG
- **WiFi codes**: scan to join, no typing the password
- **Terminal preview**: render the code as ASCII art in the conversation

## How to run it

Use the Bash tool with Python's `qrcode` library — small and fully local.

```bash
python -c "import qrcode" 2>/dev/null || pip install -q "qrcode[pil]"

# Link or text -> PNG
python - <<'PY'
import qrcode
qrcode.make("https://u-claw.org").save("qrcode.png")
print("saved -> qrcode.png")
PY

# WiFi code (scan to connect)
python - <<'PY'
import qrcode
ssid, pwd, enc = "MyWiFi", "password123", "WPA"   # enc: WPA / WEP / nopass
data = f"WIFI:T:{enc};S:{ssid};P:{pwd};;"
qrcode.make(data).save("wifi-qr.png")
print("saved WiFi code -> wifi-qr.png")
PY

# ASCII preview, no file written
python - <<'PY'
import qrcode
q = qrcode.QRCode(); q.add_data("https://u-claw.org"); q.make()
q.print_ascii(invert=True)
PY
```

## Working notes

- Confirm what the user wants encoded, and whether they want a file saved
- After generating, use the Read tool to show the PNG back to the user
- Long content produces a dense, hard-to-scan code — suggest a short link instead
- WiFi passwords are credentials: write them to the local PNG only, never echo
  them into a message or a filename
