PydanticAI Target¶

"""Red team a Pydantic AI agent (routed through the Orq AI Router).

Wrap any ``pydantic_ai.Agent`` as an ``AgentTarget`` with ``PydanticAITarget``.
The target threads Pydantic AI's typed message history internally across turns, so
multi-turn attacks build real context. Tool calls (``@agent.tool_plain``) are
surfaced to the judge.

The agent's model runs on the Orq router via an ``OpenAIProvider`` keyed with
``ORQ_API_KEY`` — no OpenAI key needed. The attacker + judge auto-route too.

Prerequisites:
    - uv add "evaluatorq[redteam,pydantic-ai]"
    - ORQ_API_KEY set (the agent's model, the attacker LLM, and the judge)

Usage:
    ORQ_API_KEY=orq-... python examples/redteam/19_pydantic_ai_target.py
