Use when asked to "create complex artifact", "build React artifact with routing", "use shadcn/ui components", "create stateful web app artifact", or "build multi-component frontend". Provides initialization scripts, development workflow, and Parcel bundling to create sophisticated single-HTML artifacts with state management and modern components. Works with React/TypeScript stack for claude.ai artifacts requiring complexity beyond simple HTML/JSX.
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.
