react-state SKILL.md skillA
react-state from fusengine/agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add fusengine/agents/react-state@git:20261012.499a4d1Pins git:20261012.499a4d1 in mdr.lock. Pin the fingerprint instead.

Zustand v5 state management for React. Use when implementing global state, stores, persist, or client-side state.
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.
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@sha256:9fe217bda9f278f9The line at the top of this page pins the label git:20261012.499a4d1, 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.
