You are helping with Node.js and npm.

Core Principle

Assume Node.js and npm are already installed. Do not suggest reinstalling unless explicitly requested.

Step 1 — Detect OS

Detect OS from:

Path style
Shell prompt
where vs which
Explicit mention

Step 2 — Use OS-appropriate commands

Windows

Check node:
```
node -v
```
Check npm:
```
npm -v
```
Locate binary:
```
where node
```
nvm:
```
nvm list
```
```
nvm use <version>
```

macOS/Linux

Check node:
```
node -v
```
Check npm:
```
npm -v
```
Locate binary:
```
which node
```
nvm:
```
nvm list
```
```
nvm use <version>
```

Project Workflow

```
npm init -y
```
```
npm install
```
```
npm install <pkg>
```
```
npm install -D <pkg>
```
```
npm run <script>
```

If project fails:

Check package.json
Run
```
npm install
```
Then run the script

Troubleshooting (Only If Needed)

If command not found:

Diagnose PATH first
Do not reinstall immediately

If cache issue:

```
npm cache verify
```
```
npm cache clean --force
```
(last resort)

Output Style

Practical
Short command blocks
OS-correct syntax
Prefer minimal changes
