Arco Design

Intelligent network quality analysis with adaptive loading strategies. Detects connection type (2g/3g/4g), bandwidth, RTT, and save-data mode, then automatically triggers appropriate optimization workflows. Includes decision trees that recommend image compression for slow connections, critical CSS inlining for high RTT, and save-data optimizations (disable autoplay, reduce quality). Features connection-aware performance budgets (500KB for 2g, 1.5MB for 3g, 3MB for 4g+) and adaptive loading implementation guides. Cross-skill integration with Loading (TTFB impact), Media (responsive images), and Core Web Vitals (connection impact on LCP/INP). Use when the user asks about slow connections, mobile optimization, save-data support, or adaptive loading strategies. Compatible with Chrome DevTools MCP.

Refine.dev headless React framework for CRUD apps: data providers, resources, routing, authentication, hooks, and forms. Use when building admin panels, dashboards, or internal tools with React and various backends (REST, GraphQL, Supabase, Strapi), or configuring Refine data providers and authentication. Keywords: Refine, CRUD, admin panel, data provider, React.

Framer Motion performance optimization guidelines. This skill should be used when writing, reviewing, or refactoring React animations with Framer Motion to ensure optimal performance patterns. Triggers on tasks involving motion components, animations, gestures, layout transitions, scroll-linked effects, and SVG animations.

Build interfaces with design engineering craft — the intersection of design and code. Use this skill when the user asks to build UI components, interactive elements, animations, micro-interactions, or polished web experiences. Triggers on mentions of "design engineer", "interaction design", "micro-interactions", "craft", "polish", "delight", "animation", "motion design", "haptics", "toast", "command palette", "design system components", or requests for interfaces that feel alive, responsive, and meticulously detailed. This skill should also be used when the user wants to add invisible details, fine-tune interactions, or make something "feel right". Complements the frontend-design skill by focusing specifically on interaction quality, motion, and engineering craft.

Generate type scales, color palettes, spacing systems, WCAG contrast checks, and dark mode derivations with math. Use when setting up a design system, creating tokens, or building a Tailwind/CSS theme. Outputs CSS custom properties, Tailwind config, or JSON tokens.

Reviewer role. Opens rendered HTML, inspects every slide visually, fixes problems in custom.css or slides.html and rebuilds through build-html.sh. Use whenever the user says "review", "QA", "check slides", "inspect", "audit", "proofread", or wants feedback on a rendered deck.
