LazyAGI/LazyLLM ? reverse-engineered prompt

Build me a simple low code Python app with LazyLLM that shows how to make a multi agent assistant.

I want a web based chatbot that can answer general questions, do retrieval over my own documents, and route special requests like speech, image questions, text to speech, and maybe drawing or music prompts to the right agent. Keep it easy to run locally, but let it use either an online model or a local model if I set one up.

Please include a clean demo workflow, basic document upload or folder loading for RAG, and a simple UI so I can try it right away. If there are current setup details or best practices in the docs, look them up online if you need to. Also make it easy to start from one command and leave the code organized so I can extend it later.
