Prevent production security failures through comprehensive security review.
Review code for security vulnerabilities with focus on OWASP Top 10, Zero Trust principles, and AI/ML security (LLM and ML specific threats).
**Analyze what you're reviewing:**
1. **Code type?**
2. **Risk level?**
3. **Business constraints?**
