// Generate QR codes locally without third-party services or dependencies. Uses a self-contained pure Python script (stdlib only). Data never leaves the machine. Supports PNG file output.
Add device sensor data to a Meta Display Glasses webapp — IMU (accelerometer, gyroscope, orientation) via DeviceMotionEvent/DeviceOrientationEvent, and GPS location via navigator.geolocation. Use when the user wants motion tracking, compass, level tool, step counter, shake detection, head tracking, or location.
Add client-side data persistence to a Meta Display Glasses webapp using the W3C Web Storage API (localStorage and sessionStorage). Use when the user wants to save settings, cache data, persist state, or store user preferences.
Add UI components to a Meta Display Glasses webapp — screens, buttons, lists, cards, forms, toggles, counters, or nav bars. Works with vanilla JS and React apps. Use when the user wants to add any interactive UI element or new screen.
Connect a Meta Display Glasses webapp to REST APIs or WebSockets. Use when the user wants to fetch data from an API, add real-time updates, show loading/error states, or cache API responses.
Create a new webapp for Meta Display Glasses with D-pad navigation and 600x600 dark-theme display. Use when the user wants to build a new glasses app, start a project, or scaffold a webapp for smart glasses.
Add a 3-digit combination lock passcode screen to a Meta Display Glasses webapp to gate public access during testing. Offered as an opt-in step within /test-on-device since Vercel deployment protection is disabled for glasses browser compatibility.

Generate QR codes locally using a pure Python script with zero external dependencies. All data stays on the local machine — nothing is sent to any third-party service.
The QR generator script is at:
.claude/skills/qr-code/scripts/qr_generator.py
Run it with python3 (macOS/Linux) or python (Windows).
Save the QR code as a PNG image file:
python3 .claude/skills/qr-code/scripts/qr_generator.py --png /tmp/qr_output.png "https://example.com"
| Flag | Description | Default |
|---|---|---|
--png FILE | Save as PNG to FILE | (required) |
--scale N | PNG pixels per QR module | 10 |
--open | Open the PNG in the OS default image viewer after saving | off |
--png <path> --open to save as PNG and open it for scanningGenerate QR for a URL:
python3 .claude/skills/qr-code/scripts/qr_generator.py --png /tmp/link_qr.png --open "https://meta.com"
Generate QR for plain text:
python3 .claude/skills/qr-code/scripts/qr_generator.py --png /tmp/message_qr.png --open "Thank god it's Friday!"
