Great apps need more than a working back end, they need a thoughtful user experience. Instead of jumping straight into vibe coding and chasing individual features, this episode of Build It walks through creating a complete front-end design spec for our smart personal trainer app with zero coding required.
Rather than asking an AI model to generate the entire spec in one shot, you will see how to prompt Gemini in Google Antigravity to build a custom two-agent team: a conversational Planning Companion that acts as a thinking partner and explains front-end concepts in plain English, paired with a dedicated Scribe agent that documents every finalized decision. Follow along as we turn prototype screenshots from Google AI Studio into a clear visual roadmap covering pages, component layouts, user flows, and natural language test cases.
Chapters:
0:00 - Intro: Why front end design specs beat vibe coding
1:19 - Prompting Gemini to build a custom agent team
2:57 - Designing an AI thinking partner and teaching companion
4:47 - Separating the planning companion from the scribe agent
5:43 - Starting a fresh session with the client planning agent
6:49 - Turning AI Studio prototype screenshots into a UI roadmap
7:37 - Learning front end concepts play-by-play (pages and components)
9:00 - Applying your design taste without the mental overhead
9:40 - Reviewing the complete front end design spec
