How to use the React State Management agent skill

What the skill makes the agent do

Once installed, the agent gets a structured reference for managing data in React apps. It can explain which state tool fits a project: local component state, a global store such as Zustand or Redux Toolkit, or server-data caching with React Query. It can also write starter code, such as a Zustand store, and help migrate legacy Redux code to Redux Toolkit.

The skill works from written guidance and examples. It does not run anything on its own, and the source does not say it checks library versions, so confirm details against the current docs for the libraries you use.

• Compares state categories: local, global, server, URL and form state
• Suggests a library based on app size and how much server interaction you have
• Writes a Zustand store with devtools and persist middleware
• Shows how to convert legacy Redux reducers and action creators to a Redux Toolkit slice

Install the react-state-management skill

Download the skill ZIP from this page. You can install it in one of two ways.

For Claude Code, unzip the file into ~/.claude/skills/ to make it available in all your projects, or into a project's .claude/skills/ folder to limit it to that project. For the Claude apps, upload the ZIP under Settings → Capabilities → Skills.

• Personal install: unzip into ~/.claude/skills/
• Project install: unzip into your project's .claude/skills/
• Claude apps: Settings → Capabilities → Skills, then upload the ZIP

Check the skill folder structure

After unzipping, the skill folder should contain SKILL.md and a references folder with details.md. SKILL.md holds the main guidance and quick-start code. references/details.md holds longer pattern documentation, which the agent reads when the main guidance is not enough.

• SKILL.md: overview, selection criteria, Zustand quick start, best practices, Redux migration guide
• references/details.md: Redux Toolkit with TypeScript pattern and worked examples

Trigger the skill with natural requests

You do not need a special command. Describe what you are doing in plain language that touches on state. The skill's description covers setting up global state, managing server state, and choosing between state management solutions, so requests on those topics are the most likely to load it.

Name the library when you know it. Mentioning Zustand, Redux Toolkit, Jotai or React Query makes the match more direct.

• "Which should I use for global state in my React app, Zustand or Redux Toolkit?"
• "Write a Zustand store for user and theme with persistence."
• "Help me migrate this legacy Redux reducer to Redux Toolkit."
• "Should server data from my API live in React Query or in a global store?"

What you need before you start

The skill assumes a React project, and its examples use TypeScript. You install the libraries yourself in your own project, such as zustand, @reduxjs/toolkit, jotai or @tanstack/react-query. The skill does not install them for you.

The skill does not run scripts and does not use the network, according to its listing. Review any code it writes before you add it to your project.

• A React project, ideally with TypeScript
• The libraries you choose, installed by you in the project
• Your own review of generated code before use

Safety notes on scripts and network access

The listing states that this skill runs no scripts and uses no network access. Its contents are Markdown guidance and code examples. That means the risk is mainly in the code you copy, not in the skill executing actions on your machine.

Treat generated store code like any other code: read it, run your tests, and check it against current library documentation.

• Runs scripts: no
• Uses network: no
• Generated code is a suggestion, not verified against current library releases

Tips for getting better results

Give the agent your app's context: how big it is, whether it already uses a store, and what kind of data it handles. The skill's own advice is to keep state close to where it is used, separate server state from client state, and pick one primary solution per category.

Ask for one decision at a time. A good first request is which tool fits your app, then a follow-up asking for starter code for that tool.

• State the app size and existing libraries in your request
• Keep server data in React Query rather than copying it into a global store
• Avoid storing derived data; compute it instead
• Ask for a narrow change, such as one store or one slice, rather than a full rewrite
