woofy

A tiny 3D Shiba Inu that lives in the corner of your screen and keeps you company while you use Claude Code. Barks when Claude finishes a turn or needs input, does little idle animations while Claude is working, gets bored if ignored, and has stats you can feed/pet/play with.

240×240 transparent window, bottom-right, always-on-top. Designed to be a notification you can see, hear, and care about.

Install

npm install -g claude-woofy   # installs the woofy CLI globally
woofy install                 # explicit, opt-in: merges 5 hooks into ~/.claude/settings.json

(Or clone the repo and run npm install && node bin/cli.js install if you'd rather run from source.)

The npm package is claude-woofy but the binary it installs is just woofy. Hook install is opt-in — installing the package will not modify your Claude Code settings on its own. When you run woofy install, it merges 5 hooks into ~/.claude/settings.json, all tagged __woofy__ so woofy uninstall can strip them cleanly later:

Hook	Fires when	Puppy reacts with
SessionStart	Claude Code starts a session	auto-launches woofy if not running, greets you
UserPromptSubmit	you submit a prompt	a random idle animation
PreToolUse	Claude is about to call a tool	a head-tilt / sniff
Stop	Claude finishes a turn	bark sound + bark animation + "done!" bubble
Notification	Claude needs your input or permission	sharper double-yip bark + "heads up!" bubble

Note on size: the bundled Shiba model + PBR texture set is ~45 MB on disk, and Electron itself is ~120 MB once npm install has run. Expect ~165 MB after a full install.

First run

woofy

First time you run it in a terminal, you'll get a prompt to name your puppy:

     ╱|、
    (˙ ∆ ˙)   Welcome to woofy!
    /づ づ     A new puppy has arrived.

  What will you call them?  Biscuit

After that, the window appears in the bottom-right corner and starts idling.

CLI

woofy                 # launch in foreground (logs to stdout)
woofy start           # launch detached in the background

woofy pet             # give scritches (+happiness, +bond)
woofy feed            # fill their bowl (-hunger, +happiness)
woofy play            # play fetch (+happiness, -energy, +bond)
woofy rest            # tell them to rest (+energy)

woofy stats           # print current stats from ~/.woofy/state.json
woofy name <name>     # rename
woofy wander          # force a bottom-strip wander

woofy bark            # send a test "done" bark
woofy alert "hey"     # send a test alert bark with an optional message

woofy anims           # list all 83 animation clip names
woofy anims sit       # filter by substring
woofy anim digging    # play a specific clip

woofy install         # re-install the Claude Code hooks
woofy uninstall       # remove the __woofy__-tagged hooks

Interaction

• Left-click the dog → pet
• Press-and-drag the dog → moves the window anywhere on the screen
• Right-click the dog → radial menu:
  • ❤️ pet
  • 🦴 feed
  • 🎾 play
  • 💤 rest
  • 🚶 walk-to — click anywhere on the screen and the dog walks there
  • 👋 bye — friendly bark + clean shutdown (state is persisted)
• Hover the window → HUD fades in showing mood, name, happiness, fullness, energy, bond

Companion state

State lives at ~/.woofy/state.json and persists across restarts. Hunger, energy, happiness, and bond drift over time (about 2 hours from fed to starving). The puppy gets bored after 3 minutes of no activity (curls up) and dormant after 10 (lies down to sleep). A sudden burst of tool calls from Claude triggers an "overwhelmed" double-bark reaction.

Mood is derived from the stats: hungry, tired, wary, lonely, playful, or content — and it actually changes how the puppy behaves:

• Bubbles are colored by mood (a hungry puppy says "kibble?" instead of "watching", a playful one says "let's goo!"; the mood emoji occasionally prepends the line)
• Idle fidgets are mood-biased (playful → in-place jumps; tired → slow idles; hungry → ground-sniffing / drinking; wary → defensive crouch)
• Wandering happens more when playful, rarely when tired/hungry, and is skipped entirely when wary
• Bark pitch and pacing scale with energy — low-energy woofs are slower and lower; high-energy yips snap and pitch up

Uninstall

woofy uninstall              # strips the 5 __woofy__-tagged hooks, leaves everything else alone
npm uninstall -g claude-woofy   # (or remove the local clone)

woofy uninstall only touches hook entries it added itself (anything tagged __woofy__). The rest of your ~/.claude/settings.json is left untouched.

What woofy is / isn't

• Is: a persistent desktop companion — stateful, animated, interactive, and a notification channel for Claude Code
• Isn't: a productivity tool, a dashboard, or a mic-listener. It reacts only to hook events from Claude Code
