eosphoros-ai/DB-GPT ? reverse-engineered prompt

Build me an open source AI data assistant that can connect to databases, CSV and Excel files, and a knowledge base, then let me ask questions in plain English and have it figure out the SQL or code it needs to answer.

I want it to be able to analyze data step by step, run safe code in a sandbox, generate charts and simple reports, and save reusable skills for common business tasks. It should feel like a workspace where someone can explore data, ask follow up questions, and get clear insights instead of just raw query results.

Also give it a clean web app so I can start a conversation, connect a data source, and see results, summaries, and visuals in one place. If you need current setup or library details, look them up online and use the latest docs.
