"""
Runnable demo: OpenAI Agents SDK multi-agent + SourceryKit — customer support specialists.

Three specialist agents each query a different mock support table:
- Order Status Specialist: queries the orders table
- Return Policy Specialist: queries the policies table
- Account Balance Specialist: queries the accounts table

Each specialist agent is converted to an Orchestrator tool via `agent.as_tool()` with a
`custom_output_extractor` to automatically generate `HandoffPayloads` upon execution.

Run:
    python agent_run.py
    python agent_run.py --tamper   # Order status value tampered → CAUGHT
