Auto-enforce TanStack Query best practices with factory key pattern. Activates when creating queries, mutations, managing server state, or implementing data fetching in React applications.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# TanStack Query Patterns
This skill enforces TanStack Query best practices for server state management in React applications.
## Query Key Factory Pattern
The factory pattern provides type-safe, hierarchical query keys:
```typescript
// lib/query-keys.ts
export const queryKeys = {
posts: {
all: () => ['posts'] as const,
lists: () => [...queryKeys.posts.all(), 'list'] as const,
list: (filters: PostFilters) => [...queryKeys.posts.lists(), filters] as const,
details: () => [...queryKeys.posts.all(), 'detail'] as const,
detail: (id: string) => [...queryKeys.posts.details(), id] as const,
comments: (id: string) => [...queryKeys.posts.detail(id), 'comments'] as const,
},
users: {
all: () => ['users'] as const,
detail: (id: string) => [...queryKeys.users.all(), id] as const,
profile: () => [...queryKeys.users.all(), 'profile'] as const,
},
auth: {
session: () => ['auth', 'session'] as const,
},
} as const
```
## Query Options Factory
Define reusable query options for consistency:
```typescript
// features/posts/queries/postQueries.ts
import { queryOptions } from '@tanstack/react-query'

How to install
mdr add smicolon/ai-kit/TanStack Query Patterns@sha256:22667e940703f0faThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
