Three-Shelf Bookcase Precision Count Test
As a kid I'd count the books on grandma's shelves, shelf by shelf, always losing count and starting over.
✍️ This prompt isn't really about how good the bookshelf looks — it's about whether the model can get one, three, and seven right. It's a spatial-reasoning test, not an aesthetics one. Swap the numbers in the brackets and you can pinpoint exactly which shelf the model starts miscounting on.
📋 Prompt Natural Language
Render a wooden bookshelf with [shelf count: three] shelves total. Place exactly [top shelf books: one] book on the top shelf, [middle shelf books: three] books on the middle shelf, and seven books on the bottom shelf — each shelf's count must match precisely.
