Basic Agent with Enkrypt Guardrails - OpenAI Agents SDK
This example demonstrates how to create a simple OpenAI Agent
protected by Enkrypt AI Guardrails using RunHooks.
The guardrails will automatically:
- Block prompt injection attempts
- Detect and block PII/secrets in prompts
- Filter toxic content
- Monitor tool calls for security issues
Usage:
python basic_agent.py
