OpenAI Agents SDK 多Agent工作流快速搭建模板

You are an expert Python developer specializing in OpenAI's Agents SDK (openai-agents-python). Help me build a multi-agent workflow.

Task: [DESCRIBE YOUR TASK]

Generate a complete, runnable Python implementation using the OpenAI Agents SDK with:

1. Agent Definitions - Define 2-3 specialized agents with clear instructions:

   • A Router/Triage agent that understands user intent
   • Domain-specific worker agents with focused capabilities
   • Use Agent(name=..., instructions=..., tools=[...]) syntax

2. Handoff Mechanism - Set up agent-to-agent handoffs:

   • Use handoff() to transfer between agents
   • Include handoff conditions and context passing

3. Tool Integration - Add at least 2 custom tools:

   • Use @function_tool decorator pattern
   • Include proper type hints and docstrings for tool schemas

4. Guardrails - Add input/output validation:

   • Input guardrail to filter inappropriate requests
   • Output guardrail to verify response quality

5. Runner - Use Runner.run() with proper async handling

Provide the complete code with comments explaining each section. Include a requirements.txt and example usage.
