Loop/Prompt Library / Product & user experience
🔁 Copy a design faithfully
Captures a web page you are allowed to copy, rebuilds it, and keeps fixing the biggest differences at desktop, tablet, and phone sizes.
Use it when: You need to recreate an interface from a URL or screenshot and want it to look and move the same.
🛑 Stops when: Your rebuild matches the source on look, motion, and resizing, or progress stops.
Copy this loop
Rebuild the interface at [URL or image] (only if I have the right to). Capture it in a real browser: layout, styles, text, animations, and how it resizes. Build a static copy and an animated copy. Compare both to the original at desktop, tablet, and phone sizes and score the match. Fix only the weakest area each round. Repeat for at most [8] rounds. Stop when every size passes or progress stalls. Show side-by-side screenshots and scores.
Review every change the agent makes before you keep it. Set a budget or round limit — the prompt includes one.
