The designer's role can stretch further than handoff. I shipped Flair without knowing how to code or how to ship an app. AI got me surprisingly far, but the biggest lesson was where it stopped helping. AI answers the questions you know to ask. It can't tell you what you don't know exists. When I hit a wall on trying to make iterations or saving my work, going back and forth with AI was slower than asking my developer friends, who introduced me to concepts I didn't have words for yet, like repositories and how a project is set up. One conversation with them saved me days of guessing.
Knowing which tool or person fits the problem is a design skill. I used AI for speed, people for context, and my own taste to decide what was worth building at all. That judgment, not the ability to write code, is what got Flair out the door.
