Is your kitchen contractor an unthinking robot with no opinions or thoughts of their own that has never used a kitchen? Obviously if you want a specific cabinet to go in a specific place in the room, you're going to have to give the kitchen contractor specifics. But assuming your kitchen contractor isn't an utter moron, they can come up with something reasonable if they know it's supposed to be the kitchen. A sink, a stove, dishwasher, refrigerator. Plumbing and power for the above. Countertops, drawers, cabinets. If you're a control freak (which is your perogative, it's your kitchen after all), that's not going to work for you. Same too for generated code. If you absolutely must touch every line of code, code generation isn't going to suit you. If you just want a login screen with parameters you define, there are so many login pages the AI can crib from that nondeterminism isn't even a problem.
