Hands-On with Agents SDK: Safeguarding Input and Output with Guardrails

A practical exploration of implementing input and output guardrails for multi-agent systems is provided using the OpenAI Agents SDK. Guardrails are presented as essential safeguards to ensure safety, maintain focus, and prevent misuse or resource waste in AI applications. The tutorial demonstrates how to build both an LLM-powered input guardrail for off-topic detection and a simple rule-based guardrail for identifying prompt injection attempts. It includes Python code examples that utilize Pydantic models and specific decorators from the SDK to create these protective layers for an agentic application.
