DevilsBreath/Tax_RAG ? reverse-engineered prompt

Build me a fully local Indian tax question answering app that works offline and keeps everything private.

I want to drop in a set of government tax PDFs like the Income Tax Act, GST laws, and ITR instructions, then have the app ingest them, search them intelligently, and answer user questions with clear source citations and page numbers for every answer. It should feel trustworthy and practical for tax compliance, not like a generic chatbot.

Please make a simple web app with a polished chat interface, plus a backend that serves the chat requests and a way to load and update the documents. If you can, also include a basic command line chat option and a simple evaluation script so I can check how well the answers match a small golden set of tax questions.

Use only local models and local search, no API keys or external services. If anything is unclear, look up the current docs online and fill in the gaps as needed.
