What it does

Zustand is an agent skill from pproenca/dot-skills. Zustand state management best practices for React applications. Use when writing, reviewing, or refactoring Zustand stores to ensure optimal performance and maintainability. Triggers on tasks involving state management, stores, selectors, re-renders, and Zustand patterns.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 49 other files, including reference files and assets (for example `assets/templates/_template.md`, `metadata.json` and `references/_sections.md`).

It sits in Frontend & Design, covering State management. It works with Zustand and React. The repository describes itself as: A collection of AI agent skills following the Agent Skills open format. The licence is MIT.

Workflow steps

8 steps, taken from the step headings in SKILL.md.

State Updates (MEDIUM-HIGH)
Middleware Configuration (MEDIUM)
SSR and Hydration (MEDIUM)
TypeScript Patterns (LOW-MEDIUM)

What it can do on your machine

Read from SKILL.md and the folder at commit cf93c57. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Zustand loads about 1.7k tokens when it runs, and up to ~25k if it reads all its reference files. Until then it costs about 70 tokens; SKILL.md has 490 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~70
When it runs · the whole SKILL.md, loaded when a task matches: ~1.7k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~25k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Community Zustand Best Practices

Comprehensive performance and architecture guide for Zustand state management in React applications. Contains 43 rules across 8 categories, prioritized by impact from critical (store architecture, selector optimization) to incremental (advanced patterns).

When to Apply

Reference these guidelines when:

Creating new Zustand stores
Optimizing re-render performance with selectors
Implementing persistence or middleware
Integrating Zustand with SSR/Next.js
Reviewing code for state management patterns

Rule Categories by Priority

Priority	Category	Impact	Prefix
1	Store Architecture	CRITICAL	`store-`
2	Selector Optimization	CRITICAL	`select-`
3	Re-render Prevention	HIGH	`render-`
4	State Updates	MEDIUM-HIGH	`update-`
5	Middleware Configuration	MEDIUM	`mw-`
6	SSR and Hydration	MEDIUM	`ssr-`
7	TypeScript Patterns	LOW-MEDIUM	`ts-`
8	Advanced Patterns	LOW	`adv-`

Quick Reference

1. Store Architecture (CRITICAL)

store-multiple-stores - Use multiple small stores instead of one monolithic store
store-separate-actions - Separate actions from state in dedicated namespace
store-event-naming - Name actions as events not setters
store-colocate-logic - Colocate actions with the state they modify
store-avoid-derived-state - Derive computed values instead of storing them
store-domain-boundaries - Organize stores by feature domain

2. Selector Optimization (CRITICAL)

select-always-use - Always use selectors never subscribe to entire store
select-atomic-picks - Use atomic selectors for single values
select-stable-returns - Ensure selectors return stable references
select-custom-hooks - Export custom hooks not raw store
select-auto-generate - Use auto-generated selectors for large stores
select-memoize-computed - Memoize expensive computed selectors
select-avoid-inline - Define selectors outside components

3. Re-render Prevention (HIGH)

render-use-shallow - Use useShallow for multi-property selections
render-equality-fn - Provide custom equality functions when needed
render-memo-children - Memo children affected by parent store updates
render-subscribe-external - Use subscribe for non-React consumers
render-avoid-object-returns - Avoid returning new objects from selectors
render-split-components - Split components to minimize subscription scope

4. State Updates (MEDIUM-HIGH)

update-functional-set - Use functional form when updating based on previous state
update-immutable - Never mutate state directly
update-shallow-merge - Understand set() shallow merge behavior
update-async-actions - Handle async actions with loading and error states
update-batch-updates - Batch related updates in single set call

5. Middleware Configuration (MEDIUM)

mw-devtools-actions - Name actions for DevTools debugging
mw-persist-partialize - Use partialize for selective persistence
mw-persist-migration - Version and migrate persisted state
mw-immer-nested - Use immer for deeply nested state updates
mw-combine-order - Apply middlewares in correct order
mw-slice-middleware - Apply middleware at combined store level

6. SSR and Hydration (MEDIUM)

ssr-skip-hydration - Use skipHydration in SSR contexts
ssr-manual-rehydrate - Manually rehydrate on client mount
ssr-hydration-hook - Use custom hook to prevent hydration mismatch
ssr-check-window - Guard browser APIs with typeof window check

7. TypeScript Patterns (LOW-MEDIUM)

ts-state-creator - Use StateCreator for slice typing
ts-middleware-inference - Preserve type inference with middleware
ts-separate-types - Separate state and actions interfaces
ts-generic-selectors - Type selectors for reusability
ts-bound-store - Type combined stores correctly

8. Advanced Patterns (LOW)

adv-context-stores - Combine Zustand with React Context for dependency injection
adv-transient-updates - Use subscribe for transient updates
adv-computed-getters - Implement computed state with getters
adv-third-party-integration - Integrate with React Query and SWR

How to Use

Read individual reference files for detailed explanations and code examples:

Section definitions - Category structure and impact levels
Rule template - Template for adding new rules

Can I use Zustand in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add pproenca/dot-skills --skill zustand -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/zustand, .gemini/skills/zustand, .github/skills/zustand and .opencode/skills/zustand in your project.

What does Zustand need to run?

SKILL.md names no scripts, command-line tools or credentials: Zustand is instructions for the agent only.

Does Zustand access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Zustand safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Zustand use?

Zustand is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Zustand use?

About 1.7k tokens (SKILL.md is roughly 6.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 23k tokens, read only when the agent opens those files.
