Mu Pet

Animated pixel art desktop pet that roams the screen as an always-on-top Electron overlay. The pet avoids the cursor and active windows, walks along screen edges, climbs walls and ceilings, and responds to agent state changes via a local HTTP API. Use when a user wants a desktop companion, screen buddy, desktop mascot, virtual pet, or visual indicator of agent activity. Supports states like idle, walking, working, thinking, sleeping, and talking (faces user with speech bubble). macOS only.

Install

Desktop Pet

A pixel art desktop pet (default: lobster 🦞) that roams the screen as a transparent Electron overlay.

Quick Start

cd <skill-dir>/assets/app
npm install
npx electron .

The pet starts at the bottom center of the screen and begins roaming.

HTTP API

Local API on port 18891 (127.0.0.1 only):

GET /state - returns {"state":"idle","statusText":""}
POST /state - set state: {"state":"talking","bubble":"hello!"}

States

State	Behavior
`idle`	Gentle bob, occasional claw snap
`walking`	Moves along current surface
`climbing`	Transitions between floor/walls/ceiling
`fleeing`	Running from cursor or active window
`working`	Sits at tiny laptop with sparkle particles
`thinking`	Slow sway, thought dots appear
`sleeping`	Eyes closed, zzz bubbles float up
`talking`	Faces user, shows speech bubble, auto-returns to idle
`snapping`	Claw snap animation

Agent Integration

Hit the API at the start of responses to make the pet face the user:

curl -s -X POST http://127.0.0.1:18891/state \
  -H 'Content-Type: application/json' \
  -d '{"state":"talking","bubble":"working on it..."}'

Set to working during long operations, thinking while reasoning.

The talking state auto-returns to idle after the bubble duration expires.
