RobuRishabh/Medical_Coding_AI_Agent ? reverse-engineered prompt

Build me a Streamlit app that acts like a medical coding study assistant.

I want a chat interface where I can ask coding questions and get clear answers with reasoning and source citations, using the study materials I upload plus current web search when needed. I also want a practice test mode where I can upload a PDF test and a PDF answer key, have the app extract the questions, answer them automatically, and then show me the score, detailed explanations, and a downloadable results report.

Please make it work with an OpenAI API key, use the provided medical coding PDFs as the knowledge base, and keep the answers consistent and careful. If you need to look up current docs online while building it, go ahead. I’d also like a simple setup so I can run the PDF processing first, then launch the app and use both chat and test runner from one place.
