# zustand-patterns

A reference for Zustand 5.x state management: slices, middleware, Immer, useShallow, persistence and devtools. Useful when you want to drop Redux without the boilerplate.

## What it does

The skill activates on files matching `**/store/**`, `*.store.*` or `*.zustand.*`. It documents seven core patterns with TypeScript examples plus the anti-patterns: destructuring the whole store, keeping server state in Zustand, mutating state directly. It does not restate Zustand's own docs — it carries only the OrchestKit delta in `references/ork-delta.md` and the `rules/` files.

Decisions sit in tables. Slices inside a single store beat multiple stores, because cross-slice access stays simple. Immer is recommended once nesting goes three levels deep; `useShallow` covers 2–5 related values. Middleware order is fixed: immer, then subscribeWithSelector, devtools, persist. Server state belongs to TanStack Query, so Zustand keeps client-only state.

Zustand 5.0.0 or newer is required, and the skill targets Claude 2.1.277+. It runs on haiku with `Read`, `Write`, `Grep` and `Glob`, and `user-invocable: false` means you cannot call it by hand. If your project still runs Zustand 4.x, these patterns will not match your API — update the library first.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add yonatangross/orchestkit --skill zustand-patterns -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/zustand-patterns/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/zustand-patterns/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add yonatangross/orchestkit --skill zustand-patterns -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/zustand-patterns/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add yonatangross/orchestkit --skill zustand-patterns -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/zustand-patterns/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install yonatangross/orchestkit zustand-patterns
```

2. **Manually: put the files in place**
- File: `.github/skills/zustand-patterns/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add yonatangross/orchestkit --skill zustand-patterns -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/yonatangross/orchestkit --path src/skills/zustand-patterns
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/zustand-patterns/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add yonatangross/orchestkit --skill zustand-patterns -a opencode
```

### Claude.ai

**Claude.ai**

## When to use it
- split a large store into typed slices
- stack middleware in the right order
- cut re-renders with `useShallow`
- persist state with schema migrations between versions
- keep server state out of the client store

## Example prompts
- Create a typed Zustand store with two slices: cart and user
- Check my store against Zustand anti-patterns and list what to rewrite
- Set up persist with partialize and a migration from version 1 to 2

# Zustand Patterns

Modern state management with Zustand 5.x - lightweight, TypeScript-first, no boilerplate.

## Overview

- Global state without Redux complexity
- Shared state across components without prop drilling
- Persisted state with localStorage/sessionStorage
- Computed/derived state with selectors
- State that needs middleware (logging, devtools, persistence)

## Upstream coverage (do not restate)

Zustand's own docs are the source for the mechanics. This skill carries only the OrchestKit delta
on top of them, in `references/ork-delta.md`, the `rules/` files, and the checklist.
