What problem does it solve? Choosing the right frontend library is time-consuming and inconsistent across projects. This Skill maps a described UI task to a curated, opinionated library list so you get one deliberate recommendation instead of evaluating dozens of options. ## Core Features & Use Cases - Task-to-library matching: Describe a task (toasts, command menus, OTP inputs, virtualization, drag and drop) and get a single curated recommendation such as Sonner, cmdk, input-otp, Virtuoso, or dnd kit. - Existing dependency awareness: Checks package.json first, reuses already-installed listed libraries, and flags competitors without churning dependencies. - Mismatch detection: Catches common mistakes like hand-built toasts, div-based dropdowns without focus handling, re-rendered number animations, and unvirtualized thousand-row lists. - Use Case: You ask "what should I use for a ⌘K command palette?" and receive cmdk with a one-sentence rationale, plus wiring guidance if requested. ## Quick Start Ask the agent which library to use for a specific frontend task, such as "what should I use for drag and drop in my React app?"
