What problem does it solve? Turning a product idea into consistent, buildable UX specifications is hard: visual identity, information architecture, states, and accessibility decisions get scattered across conversations and mocks. This Skill facilitates a structured UX discovery process and distills the results into two canonical contract documents — DESIGN.md (visual identity) and EXPERIENCE.md (behavior, IA, flows) — that downstream architecture and development work can consume directly. ## Core Features & Use Cases - Dual specification spines: Generates DESIGN.md following the Google Labs design.md spec (color, typography, spacing, component tokens) and EXPERIENCE.md covering information architecture, state patterns, interaction primitives, accessibility floor, and named-protagonist key flows. - Three operating modes: Create (full discovery to finalized spines), Update (apply changes against prior decisions logged in a memlog), and Validate (multi-lens reviewer gate producing HTML and Markdown validation reports). - Creative tooling and handoffs: Renders HTML color themes, design directions, Excalidraw wireframes, and key-screen mockups on demand, with optional handoff to external producers like Google Stitch, plus headless mode with JSON output schemas for automation. - Use Case: A founder says "help me plan the UX" for a journaling app; the Skill elicits decisions through discovery, renders candidate color themes and wireframes, then finalizes DESIGN.md and EXPERIENCE.md ready for the architecture and story-planning skills. ## Quick Start Ask the AI to create UX design specifications for your product idea and answer its discovery questions about brand, platforms, and key user journeys.
