Summary

Wraps your HTML artifacts with a live control panel that lets users adjust accent color, type scale, density, light/dark mode, and motion without re-prompting Claude. Changes rewrite CSS custom properties in real time and persist to localStorage across refreshes. Use it when someone likes your design 80% of the way but wants to dial in the last 20% themselves, or when you're demoing a brand system and want viewers to feel the variants live. Integrates with the Open Design viewer toolbar via postMessage or class-based protocols. The five-knob pattern is opinionated: curated color swatches instead of free pickers, ±15% scale limits to prevent layout breakage, and motion that respects prefers-reduced-motion.

oil-oil/citycraft

Create a bold, visually striking landing page — unconventional layouts, GSAP scroll animations, SVG elements, clip-path dividers, real depth and layering. Use this skill whenever the user wants a landing page, homepage, product page, marketing page, campaign page, event page, or any single-page site that needs to impress. Trigger on: 帮我做一个落地页, 做个首页, 产品展示页, 活动页, 营销页, 官网首页, landing page, product page, promo page, make me a homepage, build a product showcase, create a campaign page. Workflow: asks one question about the product, then opens a live browser preview of 57 city-inspired visual styles to click-select, lets the user pick typography/nav/color tone/hero variant/features variant/page sections interactively, then outputs a complete multi-file site (index.html + style.css + main.js + SVG sprite) with real product copy.
