Avnish1447/CodeSage ? reverse-engineered prompt

Build me a simple web app called CodeSage that acts like an AI mentor for a code repository.

I want to be able to drop in a repo or point it at one, then ask questions like how the project works, where a feature lives, what a file does, and how to make changes safely. The app should answer in plain English and use the repo itself as the source of truth, so it feels like a smart guide that knows the codebase well.

Make the UI clean and easy to use, with a chat style experience and a place to see helpful repo context when needed. If you need to look up current docs online for any setup details, do that. Keep it polished, responsive, and focused on helping someone understand and navigate a project fast.
