What problem does it solve? AI-generated frontend work often looks generic and templated, lacking product thinking, real typography hierarchy, designed interaction states, and restrained visual language. This Skill defines a consistent quality bar so every screen ships with Shipd/Linear/Vercel-level polish instead of generic AI slop. ## Core Features & Use Cases - Design Standards Enforcement: Applies rules for typography, spacing tokens, restrained color, motion timing (200ms in / 150ms out, spring curves), and complete component states (hover, loading, empty, error, dark, mobile). - Product-First Workflow: Guides work from problem and user journey through information architecture and design specification before any code is written. - Reverse-Engineering Method: Provides a structured practice for studying premium products (Linear, Vercel, Stripe, Raycast) and rebuilding their experiences with a taste database. - Use Case: When asked to build a developer competition platform, the Skill first produces a design specification covering direction, UX principles, motion, and states, then drives implementation, a senior-designer analysis pass, P0/P1 fixes, and a visual QA pass. ## Quick Start Ask the agent to build or redesign a frontend screen following the frontend-craftsmanship standards, starting with a design specification before writing any code.
