# Security Review Skill

This skill ensures all code follows security best practices and identifies potential vulnerabilities.

## When to Activate

- Implementing authentication or authorization
- Handling user input or file uploads
- Creating new API endpoints
- Working with secrets or credentials
- Implementing payment features
- Storing or transmitting sensitive data
- Integrating third-party APIs

## Security Checklist

### 1. Secrets Management

#### FAIL: NEVER Do This
```typescript
const apiKey = "sk-proj-xxxxx"  // Hardcoded secret
const dbPassword = "password123" // In source code
```

#### PASS: ALWAYS Do This
```typescript
const apiKey = process.env.OPENAI_API_KEY
const dbUrl = process.env.DATABASE_URL

// Verify secrets exist
if (!apiKey) {
  throw new Error('OPENAI_API_KEY not configured')
}
```

#### Verification Steps
- [ ] No hardcoded API keys, tokens, or passwords
- [ ] All secrets in environment variables
- [ ] `.env.local` in .gitignore
- [ ] No secrets in git history
- [ ] Production secrets in hosting platform (Vercel, Railway)

### 2. Input Validation

#### Always Validate User Input
```typescript
import { z } from 'zod'

// Define validation schema
…
