AI Agent Successfully Ports Python Codebase to Rust

Ombredanne pulled off something that sounds impossible at first. They got an AI agent to port an entire codebase from Python to Rust. Not just translate it line by line, but actually convert it to idiomatic Rust that works. So how did they actually make this happen?

Here's the thing: it wasn't magic. They had a solid test suite that caught problems immediately. The documentation was clear enough that the AI knew what each function was supposed to do. The datasets they fed the model were curated carefully. Without those three things, the agent would've produced garbage code. With them, it handled the heavy lifting.
