"""
Simple test to verify conversation_id inheritance in agent tools.

This test demonstrates that the fix for session continuity is working:
- Sub-agents inherit the conversation_id from their parent agent
- This enables memory persistence across multiple agent tool calls
- Similar to how OpenAI Agents SDK maintains thread_id for session continuity
