What problem does it solve? Turning vague product ideas into consistent, buildable UX specifications is hard: visual identity and behavioral rules end up scattered across chats, mocks, and memory. This Skill facilitates a structured elicitation process and distills the results into two canonical contract documents. ## Core Features & Use Cases - Dual specification spines: Produces DESIGN.md (visual identity tokens per the Google Labs design.md spec) and EXPERIENCE.md (information architecture, states, interactions, accessibility, key flows) that cross-reference each other. - Three modes: Create (facilitated discovery with creative tools like HTML color themes, design directions, and Excalidraw wireframes), Update (revise existing spines with conflict surfacing), and Validate (multi-lens reviewer gate with a consolidated HTML/Markdown report). - Decision audit trail: Every decision is logged to a memlog, working artifacts are promoted to mockups/ or wireframes/ at finalize, and headless mode supports automation with JSON output schemas. - Use Case: A product team starting a new app runs the skill to walk through brand, IA, and key flows, ending with finalized DESIGN.md and EXPERIENCE.md files that architecture and story-development steps consume directly. ## Quick Start Ask the assistant to create UX design specifications for your product and answer its discovery questions about brand, platforms, and key user journeys.
