Improves existing UI by converting Flow A/B-test learnings into concrete hypotheses, variants, and evaluation plans. Use when the user asks to optimize an existing screen, increase conversion/retention, or diagnose why a current UI is underperforming.

Designs new UI flows and screens using conversion-oriented patterns from Flow knowhow. Use when creating new onboarding, pricing, paywall, checkout, or product detail UI, or when the user asks to draft UI structure, copy, CTA, and information hierarchy from scratch.
