nextjs-zustand SKILL.md skillA
nextjs-zustand 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/nextjs-zustand@git:20261012.499a4d1Pins git:20261012.499a4d1 in mdr.lock. Pin the fingerprint instead.

Use when implementing global state, stores, persist, or hydration in Next.js 16 App Router Client Components with Zustand v5.
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 client-side state management in Next.js 16 App Router: the v5 currying syntax (`create<State>()((set) => ({...}))`), Context-based stores built with `createStore` from `zustand/vanilla` + `useRef` (required in App Router to avoid state leaking between requests — never a global store), and middleware composition (devtools → persist → immer, order-sensitive for TypeScript).
Covers `skipHydration` with the persist middleware plus manual rehydration in `useEffect` to avoid SSR mismatches, `useShallow` for array/object selectors, and SOLID file organization (`store.ts`, `store-provider.tsx`, `use-store.ts`). States explicitly that Zustand is Client-Components-only — never used in Server Components (fetch data directly there instead) and never used to persist auth tokens (use httpOnly cookies). Does not cover server state caching (see nextjs-tanstack-query for that).
</objective>
# Zustand for Next.js 16
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`:

How to install
mdr add fusengine/agents/nextjs-zustand@sha256:bd06e103b606fc27The 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.
