omrajnexus31173/NEXUS-AI-Powered-Student-Chatbot ? reverse-engineered prompt

Build me a student chatbot for GSFC University called GSFC Campus AI.

It should keep the current chat interface from phase 1, but connect it to a real AI backend so students can ask questions about campus life, internships, and documents. I want the app to run locally with a private server for the AI calls, and the browser should talk to it through relative API routes. Please make it safe by keeping the API key on the server only, with basic validation, rate limiting, and sensible error messages when the AI is unavailable.

The chat should support conversation history, retries, regeneration, deleting chats, and saving past conversations in the browser. Keep attachments local only, do not send files to the AI, and make sure the app never invents university facts if it does not know something. If needed, look up the current Gemini docs online and wire it up cleanly. I also want it to build and test cleanly.
