Ladybird (a new web browser), recently migrated part of their code base to a new programming language with the help of Claude Code and Codex (OpenAI’s code model). I thought this idea of human-directed LLM tasks is really great:
I used Claude Code and Codex for the translation. This was human-directed, not autonomous code generation. I decided what to port, in what order, and what the Rust code should look like. It was hundreds of small prompts, steering the agents where things needed to go. After the initial translation, I ran multiple passes of adversarial review, asking different models to analyze the code for mistakes and bad patterns.
