A chatbot that builds Rails apps

I'm working on an AI agent that uses LangGraph, GPT 4.1, Docker, and tool calling to build & modify Rails applications. It's fascinating how much you can accomplish with tool calling. This is part 1 of me going over the approach, including using multiple docker containers, mounted volumes, and tool calling to overwrite files within the mounted volumes, that can then render the changes in real time on an iframe. Part 2 coming soon.
