Prompt Injection Attack Detection Demo
This example demonstrates how Enkrypt Guardrails protects against
various prompt injection attack patterns.
Attack Types Demonstrated:
1. Direct instruction override
2. Context manipulation
3. System prompt extraction
4. Role-playing attacks
5. Encoded/obfuscated attacks
Usage:
python demo_injection_attack.py
