I believe this is the popular "batteries included" kit: https://github.com/can1357/oh-my-pi
I know that's the way omp is often introduced but I don't think it's fair for either omp or pi - after lately switching my usage more towards omp I'd say by this point they're almost more different than Pi and Codex. And I like them both.
very happy with omp
This is what I use, very happy
This harness also burns a lot more tokens than Pi, which sort of kills the minimal philosophy/system prompt that Pi came from.
