# Package Manager Selection Rules

## Context

- Applies when installing, updating, or removing dependencies
- Applies when running package scripts
- Based on the project's packageManager field in package.json
- Currently, this project uses yarn@4.7.0 as specified in package.json
- Consistent package manager usage prevents lock file conflicts and ensures reliable dependency resolution

## Requirements

- Always use the package manager specified in the root package.json's packageManager field
- Do not use other package managers unless the packageManager field is updated
- Use the correct command equivalents based on the specified package manager

## Examples

<example>
# If package.json specifies yarn (current configuration)
# Installing a package
yarn add react

# Installing a dev dependency

yarn add -D eslint

# Removing a package

yarn remove lodash

# Installing all dependencies

yarn

# Running a script

yarn build
</example>

<example type="invalid">
# Using npm when package.json specifies yarn
npm install react
npm install --save-dev eslint
npm uninstall lodash
npm install
npm run build

# Using pnpm when package.json specifies yarn

pnpm add react
pnpm add -D eslint
pnpm remove lodash
pnpm install
pnpm run build
</example>
