Ask HN: Best way to nudge AI to see UI elements in a screenshot?

Hi - I am trying to create a tool for product designers to learn and review their design. What I am looking to do is to allow designers to create a design, and pass it on to a tool to get feedback. Currently OpenAI and Anthropic models aren't that great at looking at UI elements and understanding their relationship and hierarchy (like font weights, shadows, symmetry, etc..). Any suggestions on how such a problem can be solved?
