What problem does it solve? Choosing the right frontend library is time-consuming and error-prone; this Skill maps a described task to a curated, opinionated library list so you get one deliberate recommendation instead of a menu of options. ## Core Features & Use Cases - Task-to-library matching: Covers UI primitives (base-ui, cmdk, Sonner, input-otp), motion (motion, NumberFlow, Cobe, shiki), charts (Liveline, recharts), drag and drop (dnd kit), virtualization (Virtuoso), state (zustand), and styling (clsx, cva, next-themes). - Existing-dependency awareness: Checks package.json first and flags conflicts with already-installed competitor libraries without churning dependencies. - Mismatch detection: Catches common anti-patterns like hand-built toasts, div-based dropdowns, re-rendered number animations, and unvirtualized thousand-row lists. - Use Case: You ask "what should I use for drag and drop?" and receive dnd kit as the single recommendation, with wiring guidance if requested. ## Quick Start Ask the skill which library to use for a specific frontend task such as toasts, charts, or drag and drop.
