pick-ui-library

Use dnd kit for drag and drop in React applications. It is the curated recommendation for sortable lists, draggable elements, and drop targets, and it handles the interaction complexity without manual event wiring.

Use Liveline when data points arrive live and the chart scrolls with time, such as streaming dashboards. Use recharts for everything else, including static or interactive general-purpose charts.

Use Sonner for toasts and notifications. It exists specifically for this purpose, so building toasts by hand or adapting a modal library is an anti-pattern the recommendation steers you away from.

Use clsx for ad-hoc conditional className strings. Use cva when a component has real variants like size, intent, or state that deserve a typed API. They compose, since cva accepts clsx-style inputs internally.

No. The recommendation process checks package.json first and uses a listed library if already present. If a competitor is installed, such as react-window instead of Virtuoso, it flags the recommendation without churning the dependency unless asked.

The skill says so explicitly and then recommends from general knowledge, clearly stating it has left the curated list. It does not silently substitute unlisted alternatives for covered tasks.
