At OpenAI's DevDay 2025 there was a talk called "Shipping With Codex", where Aaron Friel was introduced as tbe world's top user of Codex. He explained his method and said he would open source it soon. He hasn't yet AFAIK, so I have.

I find the technique mind-blowing efficient and efficacious. It has transformed my productivity completely. YMMV but take a look!

Excited to hear how you guys are getting your coding agents to do bigger and bigger tasks autonomously.
