xcp4/Project-Airi ? reverse-engineered prompt

Build me a desktop AI companion app that feels like a visual novel character, not just a chat box.

I want a cute animated companion on screen that can talk with me in real time, remember what we discussed, react with emotions, and change expressions and idle behavior based on the conversation. It should support voice output too, and have a polished, lively feel with smooth animations and lip sync if possible.

Please include a simple way for the assistant to use useful tools like web search, browser actions, clipboard, notifications, calculator, and file related actions, with a clear system for adding more later. It should be powered by Gemini, work in a desktop app style, and have a basic server setup so the frontend can talk to the brain logic cleanly.

If anything needs current docs or setup details, look them up online first and make it work with the latest versions.
