Editor's note

Claude Desktop Buddy is a reference implementation and C++ firmware project that exposes a Bluetooth Low Energy API letting makers connect physical hardware devices to Claude Cowork and Claude Desktop (including Claude Code). The core protocol, documented in REFERENCE.md, uses Nordic UART Service UUIDs and JSON schemas to relay permission prompts, session state, and transcripts from the desktop app to a microcontroller over BLE. The included example targets an M5StickC Plus (ESP32) and runs a desk companion that cycles through seven animated states tied to Claude activity: sleeping when disconnected, visibly agitated when an approval is pending, and celebrating every 50,000 tokens consumed. Physical buttons on the device let users approve or deny permission prompts without touching the computer. Custom GIF character packs up to 1.8MB can be pushed to the device live over BLE via a drag-and-drop target in the Hardware Buddy window. The project is aimed at hardware hobbyists and developers who want to build tangible, reactive accessories for Claude workflows.
