Here is a technique I use (in a recent livestream) to help your ai agent give better UI layouts for your apps.
Prompt:
Here’s my phone, an iPhone Pro Max. My thumb only reaches the bottom comfortably, left or right hand. Put every control the user taps in that bottom thumb zone. Use the top 65 percent as a passive zone with no controls, just the info that builds trust, like the detected input and the transcript. Make every interaction take about a second and a half, and make it so a baby could figure it out. And take out anything that isn’t pulling its weight.
