# 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
const CreateUserSche
