AbdelazizBs/deep-dive-research-agent — reverse-engineered prompt

Build me a Python web app for a deep dive research assistant. I want a simple page where someone can type a research question, submit it, and immediately see an assistant response card appear while the research job runs in the background.

The app should show live progress updates in that same card, then save everything so I can review it later. Add an admin area where I can see all research tasks, open one task, and inspect the events, fake or real model calls, usage estimates, costs, status, errors, and final report data.

Make it easy to run locally with a free demo AI mode that doesn’t need API keys, but structure it so OpenAI, Anthropic, or OpenRouter can be plugged in through environment variables. If a provider rate limits or fails, show a clear friendly message instead of crashing.

Use a clean FastAPI style app with simple server rendered pages, SQLite storage, and a health endpoint. Look up current docs online if you need to.
