# Picking The Right Library A lookup skill. When invoked with a task ("I need toasts", "what should I use for drag and drop?"), match the task to the curated list below and recommend the library. These are deliberate, taste-driven picks — don't substitute alternatives outside this list unless the user asks for one or the task genuinely isn't covered. ## How to use this 1. **Identify the task**, not the library the user named. "I need to show a dropdown" is a UI-primitives task (base-ui), even if they asked about something else. 2. **Check what's already installed.** Look at `package.json` first. If the project already uses a listed library, use it. If it uses a competitor (e.g. react-window instead of Virtuoso), flag the recommendation but don't churn the dependency without being asked. 3. **Recommend one library**, state what it's for in one sentence, and install/wire it up if that's part of the request. Don't present a menu of options when the list has a clear answer. 4. If the task isn't covered by the list, say so explicitly and recommend from your own knowledge — but be clear you've left the curated list. ## The list ### UI components & primitives | Task | Library | | --- | --- | | Unstyled, accessible UI components (dialogs, popovers, menus, selects…) | [base-ui](https://base-ui.com) | | Command menus (⌘K palettes) | [cmdk](https://cmdk.paco.me) | | Toasts / notifications | [Sonner](https://sonner.emilkowal.ski) | | One-time password / verification code inputs | [
