描述
Produce thoughtful, high-fidelity design artifacts in HTML — landing pages, slide decks, interactive prototypes, animated videos, posters, wireframes, and visual explorations. Use whenever the user asks to design, mock up, prototype, visualize, storyboard, or explore UI options — including phrases like "make a deck", "design a landing page", "prototype this flow", "animate this concept", "turn this into a clickable mockup", "show me options for X", "build a pitch deck", "create a poster", "visualize this idea", "I don't know what style I want", or "design something for <brand>". Enforces fact verification (WebSearch before assuming a product exists or its version), the Core Asset Protocol for branded work (logo and product shots and UI screenshots are first-class, not just colors and fonts), a Design Direction Advisor fallback that offers 3 differentiated directions from 10 design philosophies when the brief is too vague, commits to a visual system up front, presents multiple variations, and avoids AI-design tropes (aggressive gradients, emoji bullets, rounded-card-with-left-border, CSS-silhouettes-as-product-shots).
