What problem does it solve? Starting a new product design from zero often produces a single screen with no design system underneath, or an over-built system with every component generated regardless of need. This Skill sequences the full build — color, typography, spacing, components, screens, and flows — so each decision is made once and reused consistently. ## Core Features & Use Cases - Context Profiling: Establishes whether a design system exists, what platform is targeted, and what brand constraints apply before any artifact is generated. - Scope Ladder Composition: Walks foundations → components → screens → flows, gating each rung as core, offer, or skip so only needed skills are composed. - Validation Handoff: Passes the finished artifacts to the ux-design-review skill for audit before declaring the build done. - Use Case: A founder asks an AI assistant to design a new mobile budgeting app. The Skill sets up the color palette, type scale, and spacing system, builds only the components the dashboard and onboarding screens need, sequences the onboarding flow, then hands everything to design review. ## Quick Start Ask your assistant to help you design a new app from scratch, including the design system, key screens, and onboarding flow.
