ssafy-python-pjt/backend ? reverse-engineered prompt

Build me a Django backend for an AI agent app.

I want a simple server that can handle user requests, send them to an AI agent, and return helpful responses through an API. Please set up the project cleanly, make sure the basic Django structure works, and include whatever endpoints and models are needed so the app can actually be used and extended later.

If there are any current best practices or setup details I should follow, look up the latest docs online if you need to. Keep it easy to run locally, and make sure the README or setup steps are clear enough that I can get it working without guessing.
