Pranav322/deepdoc ? reverse-engineered prompt

Build me a Python tool called DeepDoc that I can run from the command line on an existing codebase and have it automatically generate clean engineering docs from the source.

I want it to scan the repo, figure out the main parts of the app, and create a documentation site with helpful Markdown pages, diagrams, and search. It should handle supported backend projects well, like FastAPI, Django, Go, and similar service apps, and it should be smart enough to make docs that feel organized instead of dumping one page per file. I also want an init, generate, update, serve, and deploy style workflow, so I can set it up, generate the docs, preview them locally, and export a static site.

If it can also include a chatbot mode that answers questions using the generated docs and code references, that would be great. Please make it work with common LLM providers and keep the generated site local first and easy to deploy.
