OpenAI Agents SDK for Python guardrails
This example project demonstrates how to implement different types of guardrails using the OpenAI Agent SDK for Python with Trigger.dev.
Overview
This demo is a practical guide that demonstrates:
- Three types of AI guardrails: Input validation, output checking, and real-time streaming monitoring
- Integration of the OpenAI Agent SDK for Python with Trigger.dev for production AI workflows
- Triggering Python scripts from tasks using our Python build extension
- Educational examples of implementing guardrails for AI safety and control mechanisms
- Real-world scenarios like math tutoring agents with content validation and complexity monitoring
Guardrails are safety mechanisms that run alongside AI agents to validate input, check output, monitor streaming content in real-time, and prevent unwanted or harmful behavior.

Relevant code
Trigger.dev Tasks
- inputGuardrails.ts - Passes user prompts to Python script and handles
InputGuardrailTripwireTriggered
exceptions - outputGuardrails.ts - Runs agent generation and catches
OutputGuardrailTripwireTriggered
exceptions with detailed error info - streamingGuardrails.ts - Executes streaming Python script and parses JSON output containing guardrail metrics
Python Implementations
- input-guardrails.py - Agent with
@input_guardrail
decorator that validates user input before processing (example: math tutor that only responds to math questions) - output-guardrails.py - Agent with
@output_guardrail
decorator that validates generated responses using a separate guardrail agent - streaming-guardrails.py - Processes
ResponseTextDeltaEvent
streams with async guardrail checks at configurable intervals (example: stops streaming if language is too complex for a 10-year-old)
Configuration
- trigger.config.ts - Uses the Trigger.dev Python extension
