This sounds nice and great and all, but I wonder what the output is like and if there is a measurable difference between doing the factory and trying to two shot the whole thing with claude 4 sonnet.

> When something goes wrong, I don’t hand-patch the generated code. I don’t argue with claude. Instead, I adjust the plan, the prompts, or the agent mix so the next run is correct by construction.

I don't think "correct by construction" means what OP thinks it means.

"Here’s the secret sauce: iterate the inputs":

No it isn't. There are no short cuts to ... anything. You expend a lot of input for a lot of output and I'm not too sure you understand why.

"Example: an agent once wrote code ..." - not exactly world beating.

If you believe this will take over the world, then go full on startup. YC is your oyster.

I've run my own firm for 25 years. Nothing exciting and certainly not YC excitable.

You wont with this.
