Creates scoped key-value stores, reads and writes state entries, lists keys, and performs partial updates across functions. Use when persisting data between invocations, managing user sessions, caching computed values, storing feature flags, sharing state between workers, or building a KV data layer as an alternative to Redis or DynamoDB.
Choose and implement React state management solutions including Context, Zustand, Redux Toolkit, TanStack Query, and Jotai. Use when selecting state management, implementing global state, or managing server state in React applications.
Manage client and server state with Zustand stores and React Query patterns.
Production-tested setup for Zustand state management in React applications with TypeScript. This skill provides comprehensive patterns for building scalable, type-safe global state. Use when: setting up global state in React, migrating from Redux or Context API, implementing state persistence with localStorage, configuring TypeScript with Zustand, using slices pattern for modular stores, adding devtools middleware for debugging, handling Next.js SSR hydration, or encountering hydration errors, TypeScript inference issues, or persist middleware problems. Prevents 5 documented issues: Next.js hydration mismatches, TypeScript double parentheses syntax errors, persist middleware export errors, infinite render loops, and slices pattern type inference failures. Keywords: zustand, state management, React state, TypeScript state, persist middleware, devtools, slices pattern, global state, React hooks, create store, useBoundStore, StateCreator, hydration error, text content mismatch, infinite render, localStorage, sessionStorage, immer middleware, shallow equality, selector pattern, zustand v5
Understand and use state management in Umbraco backoffice (foundational concept)
Jotai state management patterns — atoms, globalAtom, contextAtom, and persistence.
Refactor and review state management in React and TypeScript applications. Use when: refactoring component state, reviewing useState usage, choosing between local and global state, preventing unnecessary re-renders, selecting state management libraries (Zustand, Jotai, Redux), applying discriminated unions, deriving state, managing refs vs state, or eliminating prop drilling.
Simplified state file management with consolidated FLOW.md (project) and ITEM-XXX.md (per-item) files
Apply when deciding, designing, or implementing client-side state with FastStore SDK hooks like useCart, useSession, or useSearch. Covers cart manipulation, session handling, faceted search, and analytics event tracking from @faststore/sdk. Use for any interactive ecommerce feature that relies on FastStore's built-in state management.
Teaches Vue state management with stores, Pinia, and the Composition API. Use when you need to share and synchronize state across multiple components beyond what props and events can handle.
Design state schemas, implement reducers, configure persistence, and debug state issues for LangGraph applications. Use when users want to (1) design or define state schemas for LangGraph graphs, (2) implement reducer functions for state accumulation, (3) configure persistence with checkpointers (InMemorySaver/MemorySaver, SqliteSaver, PostgresSaver), (4) debug state update issues or unexpected state behavior, (5) migrate state schemas between versions, (6) validate state schema structure, (7) choose between TypedDict and MessagesState patterns, (8) implement custom reducers for lists, dicts, or sets, (9) use the Overwrite type to bypass reducers, (10) set up thread-based persistence for multi-turn conversations, or (11) inspect checkpoints for debugging.
. Use when managing application state.
