What is OpenAI harness engineering?

It's a method where AI agents build software from test harnesses alone — zero human-written code. Uses Codex/GPT models to plan, code, test iteratively.

Will harness engineering replace programmers?

Not soon. Great for prototypes, sucks at complex, secure systems needing human judgment.

How do I try OpenAI's harness framework?

Check Rohit's GitHub repo, integrate with OpenAI API. Start small — don't bet the farm. Word count: ~950.
