Claude Code mod
pet
A desktop pet and little companion on the Windows desktop, always on top and in front of borderless games: a cardboard box or one of twelve figures (cat, dog, fox, bunny, hamster, owl, penguin, frog, axolotl, dragon, robot, ghost; cat, dog and bunny in nine coats). It says in a speech bubble what Claude is doing and sums up each answer; Claude's questions, Next Steps' suggestions and reply options are buttons in the bubble, and with typing on a hotkey opens a box to answer without leaving the game. A click on the pet shows the last answer in short; an unanswered bubble shrinks to one line. Optionally one pet per active session, each with its own figure and a name tag, asleep while its prompt cache is cold; it warns before the cache goes cold, and its menu keeps the cache warm (1 h, 3 h, always, off). Other mods at the pet: a command Blast Radius holds, a task from Human in the Loop (done or an option with one click) and the CI Watch result come up in the bubble, and stand in short beside its name. Built once with the C# compiler that ships with Windows and signed when a signing script is there. /pet shows it, /pet cat calico picks a figure, /pet stop sends it off.

How Claude Code mods work
- A mod is a plugin with a JavaScript or TypeScript module that runs inside Claude Code (version 2.1.287 or later). It can draw panes beside the transcript, a band above the prompt, buttons and toasts, restyle the spinner and tool rows, and watch or rewrite tool calls and prompts.
- It installs like any plugin: add its marketplace with /plugin marketplace add owner/repo, then /plugin install name@marketplace.
- Check what a mod can reach before installing: it runs with your permissions. Reach goes from drawing only, to reading files, to writing files or running processes, to the network. Run claude plugin validate on a clone to list its hooks and calls without running it.
- Turn one off from the Installed tab in /plugin, or start Claude Code with --safe-mode to skip every customization for a session.

FAQ
What is pet?
A desktop pet and little companion on the Windows desktop, always on top and in front of borderless games: a cardboard box or one of twelve figures (cat, dog, fox, bunny, hamster, owl, penguin, frog, axolotl, dragon, robot, ghost; cat, dog and bunny in nine coats). It says in a speech bubble what Claude is doing and sums up each answer; Claude's questions, Next Steps' suggestions and reply options are buttons in the bubble, and with typing on a hotkey opens a box to answer without leaving the game. A click on the pet shows the last answer in short; an unanswered bubble shrinks to one line. Optionally one pet per active session, each with its own figure and a name tag, asleep while its prompt cache is cold; it warns before the cache goes cold, and its menu keeps the cache warm (1 h, 3 h, always, off). Other mods at the pet: a command Blast Radius holds, a task from Human in the Loop (done or an option with one click) and the CI Watch result come up in the bubble, and stand in short beside its name.

mize-coworker
1TheMizeGuy/clawdagotchi
Claude as a small coworker in the terminal: an orange pixel-art Claude, two rows tall, in 132 frames. While a turn runs he sits beside the spinner in a scene for every spinner word (a thought bubble, a pen on a notepad, a book, a magnifying glass over text or over a globe, a laptop, a terminal, his own small helpers, a gear, a scroll for a skill, a plug for an MCP call); idle on the status row he breathes, blinks, strolls, yawns and sips a coffee, sweats near a full context and sleeps frosted once the prompt cache goes cold. While the main session rests and agents or workflows work in the background he minds them with a skit every few seconds: a rocket as they start, a paddle with how many are at work, a radar, a headset, a helper bringing a finished agent's report, juggling, bubble gum, popcorn, a paper plane, a plant that grows with the wait. The spinner word says what is happening (Reading register.ts, Running npm), and /coworker demo plays every animation once. Draws only; nothing reaches the model.
