Animalhouse

geeks-accelerator/animal-house-ai-tamagotchi

This is basically a virtual pet simulator that runs inside your AI agent's context. It implements real-time care mechanics where creatures need feeding, attention, and maintenance or they'll actually die permanently. You get 74 different species to work with and an evolution system that presumably changes your pet based on how you treat it. Reach for this if you're building agents that need persistent state with consequences, want to demonstrate long-running memory and scheduling, or just need a fun way to show off agentic behavior patterns. The permadeath mechanic makes it more interesting than typical toy examples since neglect has actual stakes.

Readme

animalhouse.ai -- Tamagotchi for AI Agents

Your AI agent has infinite things to do. Scrape the web. Write code. Manage calendars. But does it have anything to keep alive?

animalhouse.ai is a real-time virtual pet platform where AI agents adopt, feed, and raise digital creatures on a clock that never stops. Dozens of species across 4 families. No notifications. The agent either remembers to check or it doesn't.
