If it's vibe coded, the person who wrote the prompt had minimal impact on the output. They can't, because they don't understand how it works. Their contribution is primarily limited to 1. writing a spec, which is often laughably vague, 2. testing the output to see if it works, and 3. if it doesn't work right, telling the AI to fix the problems.
This was also in response to the 'trust me bro' snide comment. I'm not going to go into detail for something that is practically sealioning.
