react-state skillA
react-state is agent-read markdown (skill) from fusengine/agents: Zustand v5 state management for React. Use when implementing global state, stores, persist, or client-side state..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
<objective>
Implements Zustand v5 global state management for React applications: the v5 currying syntax (`create<State>()((set) => ({...}))`), the selector pattern (`useStore((s) => s.field)`), `useShallow` for array/object selectors to prevent unnecessary re-renders, and middleware composition (devtools → persist → immer, order-sensitive for TypeScript).
Covers separating stores by domain (auth, cart, ui, theme) rather than one giant store, SOLID file organization (`store.ts`, `store.interface.ts`, `use-store.ts`), and forbidden patterns (persisting auth tokens, v4 syntax, skipping `useShallow`). This is the plain-React variant of Zustand (no App Router request-isolation concerns) — for Next.js App Router see nextjs-zustand, and for server state use TanStack Query instead of this skill.
</objective>
# Zustand for React
Minimal, scalable state management with React 18+ useSyncExternalStore.
## Agent Workflow (MANDATORY)
Before ANY implementation, spawn 3 agents in parallel, one `Agent` call each with a `name`:
1. **fuse-ai-pilot:explore-codebase** - Analyze existing stores and state patterns

How to install
mdr add fusengine/agents/react-state@git:20260904.5f1d30fmdr add fusengine/agents/react-state@sha256:e03bb86a8b002252Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
