A pixel cat that lives on your desktop — follows your cursor, reacts to typing, and gets visibly stressed out when Claude Code is grinding through a long tool call. The README undersells how much is actually going on under the hood, so here's the fuller picture.

NekoDrift is an Electron app, not a browser toy, which matters: it needs to track your cursor and keystrokes outside its own window to react in real time. That's done with uiohook-napi for global mouse/keyboard hooking from the main process, feeding a set of small, focused modules rather than one monolithic background script:

• mouse-tracker.ts / keyboard-tracker.ts — cursor-follow with smooth lag and eye tracking, plus WPM-driven "heat level" from typing speed
• idle-detector.ts — drives the mood system (happy / content / tired / lonely) based on how long you've actually been at the keyboard
• pomodoro-timer.ts / stretch-timer.ts / message-reminder.ts — the productivity side: Pomodoro sessions, stretch reminders, and scheduled daily nudges
• sprite-manager.ts — drives the pixel coat editor (a 16×16 grid, 10 colors) and the animation states
• tray.ts / window-manager.ts / ipc-handlers.ts — the usual Electron plumbing to keep a transparent, always-on-top window behaving

The Claude Code integration is its own small HTTP server (http-server.ts) running in the main process — Claude Code's hooks call into it on every tool invocation, and the cat's mood/animation state reacts accordingly. On the renderer side, the cat itself, its sprite states, onboarding flow, and settings panel are split into their own component folders rather than crammed into one view.

No files, no sound assets shipped — the sound engine (purr, meow, chime) is synthesized live via the Web Audio API. Nightly builds are published automatically from CI on every push, alongside the stable Releases.
