Tanstack Query

Reach for this when you're working with TanStack Query v5 and need to remember the breaking changes from v4, or when you're implementing infinite scroll, optimistic updates, or offline-first patterns. The skill enforces object syntax for all hooks, covers the gcTime/cacheTime rename that trips everyone up, and shows you how to use useMutationState for tracking mutations across components without prop drilling. It's essentially a migration guide and best practices reference rolled into one. Particularly handy for catching the 16+ common errors the maintainer documented, like trying to use removed query callbacks or forgetting that initialPageParam is now required for infinite queries.
