Type-safe, file-based router for React with first-class search params, data loading, and code splitting.

Casper Studios internal design system for generating consistent, production-grade SaaS UI. Use this skill whenever generating UI code for internal tools, client apps, dashboards, POCs, prototypes, or any visual interface — even quick mockups or artifacts. Apply it any time the output is a React component, page, or layout. If the user mentions "our design system", "Casper style", "match our look", or asks you to build any kind of app or interface, use this skill. Also trigger when restyling or theming existing UI to match Casper's visual language. This skill takes priority over generic frontend-design guidance.

Use when asked to "add custom card", "install HACS card", "create gauge/graph", "ApexCharts dashboard", "mushroom cards", or "bubble separator".

Use this skill whenever the user asks to animate components, add transitions, create scroll-triggered effects, implement page transitions, layout animations, gesture interactions, or any kind of motion/animation in a React or Next.js project. Also trigger when code imports 'framer-motion', 'motion/react', or 'motion/react-client', or when the user mentions: animation, transition, fade-in, slide, parallax, scroll animation, exit animation, AnimatePresence, motion.div, spring, gesture, drag, hover animation, stagger, whileInView, or layout animation.

Use this skill when you are asked to adapt an existing web app to work as a World App mini app, or to share code between a web app and a mini app. This skill covers the technical steps of migration, common issues, and debugging tips. There will be some changes required to contracts and frontend code, but the overall architecture and user experience can remain largely unchanged.
