A former Meta research engineer has built a system allowing his 9-pound cavapoo Momo to vibe code games using Claude Code. The setup routes Momo's keyboard input through a Raspberry Pi 5 to filter out special keys, then feeds the results to Claude Code, which interprets the random keystrokes as cryptic game design instructions.

Momo's owner created an elaborate prompt telling Claude to treat any input as meaningful game design from an eccentric video game designer. The system dispenses treats via a Zigbee-connected pet feeder when Claude successfully processes input, creating an automated feedback loop. Games are built in Godot 4.6 using C# for game logic, with each project taking 1-2 hours from start to playable build.

The project emerged after the creator was laid off from Meta in January. He experimented with Rust/Bevy and Unity before settling on Godot, citing better training data compatibility and Godot's text-based scene format that allows Claude to read and edit `.tscn` files directly. The keyboard setup uses a Logitech Pebble Keys 2 mounted with VHB tape to prevent chewing, while special keys are filtered out by a custom Rust application to keep Momo within the coding environment.
