manansethi1205/youtube-rag-pro ? reverse-engineered prompt

Build me a Chrome extension and backend that lets people open a YouTube video with captions and ask questions about it right on the page.

I want it to work with multiple caption languages, keep the video timeline and transcript language intact, and answer with grounded citations that jump to the exact timestamp in the video when clicked. It should also handle follow up questions, remember the conversation for the same video, and give useful answers for summaries, factual questions, and topic explanations.

Please make it feel production ready, with a clean simple UI, reliable error handling, and support for running locally or in Docker. If you need current docs for any service or library, look them up online first.

Also include the full retrieval flow behind the scenes, transcript cleaning, smart chunking, hybrid search, reranking, and basic safety checks, plus a small evaluation setup so I can test whether the answers stay accurate and cited correctly.
