the-momentum/python-ai-kit ? reverse-engineered prompt

Build me a production ready Python starter for an AI agent app that can also work as a small API service or MCP server.

I want the project to feel ready for real work, with a clean structure, good testing, logging, tracing, and a simple way to keep conversation state between sessions. It should include a basic agent workflow, a place for prompts, and a clear service layer so I can add tools and business logic without everything turning into one giant file.

Please set it up so I can use it as a template for future projects, with modern Python tooling, FastAPI for the API side, database backed storage, and a small Streamlit style interface if that fits. Add sensible defaults for security, error handling, and configuration, and make sure it is easy to extend into either an AI agent, a microservice, a monolith, or an MCP server.

If you need to check current docs for any libraries or best practices, go ahead and look them up online.
