DeskPet

A pixel-art desk pet that reacts to Claude Code's sessions over BLE, running on the M5Stack Cardputer.

Community port of [`anthropics/claude-desktop-buddy`](https://github.com/anthropics/claude-desktop-buddy) from M5StickC Plus to M5 Cardputer — landscape UI, keyboard-first interaction, fresh pixel character.

DeskPet Home screen — Claude Desktop linked, pixel pet idle
Home. Paired with Claude Desktop over BLE. The pixel pet breathes on the left while the right panel streams live session state — running task count, cumulative tokens, last activity message, and battery.

DeskPet Approval screen — Bash rm waiting for Enter/Esc
Approval pending. Claude Code wants to run rm -f /tmp/deskpet-test-nonexistent. The screen flips red, the LED pulses orange at 2 Hz, and a countdown starts. Press Enter on the Cardputer to approve or Esc to deny — the agent continues without you touching the laptop.

What it does

Advertises as Claude-DP-XXXX over BLE Nordic UART, discoverable from Claude Desktop's Hardware Buddy pairing pane
Reacts in real time to Claude Code's session state — idle, busy, approval-pending, celebrating — via seven animated pet states and a WS2812 LED
Approves or denies permission prompts directly from the Cardputer keyboard (Enter / Esc), so you don't have to interrupt flow on the laptop
Stays quiet — pet sleeps when there's no session, gentle cyan breathe when Claude is working, bright orange blink when attention is needed

Hardware
