What problem does it solve? Applications that work correctly but look merely decent often lack the visual refinement and interaction quality of premium products. This Skill provides a structured, repeatable prompt and iteration protocol to elevate an existing UI toward Stripe-level polish without a full redesign. ## Core Features & Use Cases - Battle-tested polish prompt: A ready-to-use prompt engineered with agreement framing, desktop/mobile separation, and high quality anchors, tuned for Claude Opus, GPT, and Gemini models. - Iteration protocol: Guidance for running 10+ incremental passes so small improvements compound into dramatic results, including multi-agent coordination across desktop, mobile, and animation focus areas. - Comprehensive checklists: Reference checklists covering spacing, typography, color contrast, interaction states, accessibility (WCAG), and performance for both desktop and mobile. - Use Case: Your web app functions well but feels generic. Run the polish prompt repeatedly, alternating desktop and mobile focus, tracking each pass until reviewers find no further improvements. ## Quick Start Ask the agent to polish your working app's UI/UX to Stripe-level quality, considering desktop and mobile separately, and repeat the pass multiple times.
