What problem does it solve? Starting a new project's UI without an established design system leads to inconsistent aesthetics, ad-hoc typography, and scattered color choices. This Skill researches your product and landscape, then produces a complete design system captured in a DESIGN.md file that serves as the project's design source of truth. ## Core Features & Use Cases - Design System Generation: Proposes a full system covering aesthetic direction, typography, color, layout, spacing, and motion. - Preview Pages: Generates font and color preview pages so you can evaluate choices visually before committing. - DESIGN.md Output: Writes a DESIGN.md file as the canonical design reference for the project. - Use Case: When kicking off a new web product with no brand guidelines, invoke this Skill to research the competitive landscape and produce a coherent design system with preview pages, rather than improvising styles component by component. For existing sites, use /plan-design-review to infer the system instead. ## Quick Start Ask the agent to create a design system and DESIGN.md for your new project, and it will research the landscape and propose typography, color, and layout with preview pages.
