While not on the same level as these guys, I've done some similar stuff using Claude. This is a classic synergy example, where the output of human + LLM is far greater than just the human or just the LLM working on a problem. My experience has been that the LLM lacks fine grained judgement when it comes to allocating resources, or choosing a direction to work in. But once a direction is pointed out, it can do a deep exploration of that possibility space. Left alone, it would probably just go off on a tangent. But with someone holding the leash and pointing out areas to explore, it is a very useful partner.
i've been thinking about why we call them agent harnesses
i know all analogies suck in different ways but here goes:
coding agents are like horses. without a harness and bridle they'll the horse will do as it pleases -- a human can't travel very far and fast by foot but put a bridle and a harness on a horse, give it a bit of coaxing with carrot and stick, add in a bit a pointing the thing in the right direction and bingo you're off to the races!
