描述
High-fidelity HTML design and prototype creation. Use this skill whenever the user asks to design, prototype, mock up, or build visual artifacts in HTML — including slide decks, interactive prototypes, landing pages, UI mockups, animations, or any visual design work. Also use when the user mentions Figma, design systems, UI kits, wireframes, presentations, or wants to explore visual design directions. Even if they just say "make it look good" or "design a screen for X", this skill applies.
