This has to be intentional. I refuse to believe that someone would do this unintentionally. You are literally making video of a website, the app doesn't have any other feature, yet you don't show us the example!? What causes this? It has to be intentional, but why?
They've probably just asked their agent to create code and a readme. Adding example is too complicated for AI and doing it manually is extra work.
People are too lazy to do actual work now in the age of AI.
