What problem does it solve? Designing high-fidelity UI artifacts in CLI/API environments often produces generic, templated-looking output. This Skill provides a structured design process—surface-first composition, context gathering, variation exploration, and a slop diagnostic—that produces deliberate, verified HTML design artifacts instead of default-looking mockups. ## Core Features & Use Cases - Surface-First Composition: Commits to one of seven surface archetypes (Monitor, Operate, Compare, Configure, Decide/Learn, Explore, Command/Inspect) before choosing any visual tokens, eliminating the most common cause of generic layouts. - Self-Contained HTML Artifacts: Produces single-file HTML deliverables with embedded CSS/JS for landing pages, interactive prototypes, 1920x1080 slide decks, component labs, and motion studies, with versioned revisions and optional in-page Tweaks panels. - Slop Diagnostic Audit: Scores artifacts against ten known AI design tells (tech gradients, feature-tile grids, unearned blur, wrong surface) and repairs composition, color, or decoration based on the diagnosis. - Use Case: Ask for a dashboard concept and receive a density-focused Monitor-surface HTML prototype with three layout variants, verified in a browser, rather than a centered hero with three feature cards. ## Quick Start Ask the agent to design a landing page or interactive prototype as a self-contained HTML file and save it to a local path.
