# Redux Toolkit (RTK) & RTK Query API Caching

Implements Redux Toolkit: creating slices with createSlice and Immer mutations, defining API services with createApi and fetchBaseQuery, automatic tag invalidation (providesTags, invalidatesTags), and typed hooks.

## When to Invoke
Invoke this skill whenever you need to:
- create rtk query api
- configure redux toolkit store
- invalidate tags rtk query

## Execution SOP & Rules
1. Define API with createApi: baseQuery: fetchBaseQuery({ baseUrl: '/api' }), tagTypes: ['Post'].
2. Declare queries: getPosts: builder.query({ query: () => '/posts', providesTags: ['Post'] }).
3. Declare mutations: addPost: builder.mutation({ query: body => ({ url: '/posts', method: 'POST', body }), invalidatesTags: ['Post'] }).
4. Attach API middleware to store configuration: middleware: getDefault => getDefault().concat(api.middleware).

## Verification Checklist
- Run local linting, syntax validation, and type-checks before reporting completion.
- Ensure all created or modified files adhere to workspace boundaries and avoid uncommitted secrets.
- Verify tests or build commands exit cleanly with return code 0.
