What problem does it solve? Turning early product ideas into a coherent visual design direction is chaotic: mockups scatter across tools, feedback gets lost, and there is no single shareable artifact. This Skill provides a structured four-phase workflow (Context, Explore, Iterate, Refine) that takes UI/UX concepts from open-ended exploration to one polished, shareable design brief. ## Core Features & Use Cases - Four-Phase Wide-to-Narrow Workflow: Define the product in product_overview.md, generate many mockup options, converge on consistent story flows and wireflows, then refine into a final design-brief.html. - AI Image Generation Guidance: Includes provider comparison (Google Imagen 4, OpenAI gpt-image-1.5, fal.ai Flux) and prompt patterns for maintaining visual continuity across sequential story screens using image editing APIs. - Ready-Made HTML Templates: Ships gallery, story-flow, and design-brief templates with dark mode, lightbox viewing, rating/feedback collection via localStorage, and copy-pastable feedback summaries. - Use Case: A product designer exploring a new mobile app generates 3-5 mockup variations per key screen, collects stakeholder ratings in the gallery page, builds sequential story flows with consistent visuals, and delivers a single HTML brief linking personas, color palette, wireflows, and user stories. ## Quick Start Use the brainstorm-to-brief skill to take my app concept from initial exploration through user stories and mockups to a final shareable HTML design brief.
