Use with OpenAI Agents

Install:

shell

pip install "nullrun[agents]" openai-agents

Wrap the Runner.run_sync call (or any sync / async runner) with @protect:

openai_agents_protect.py

from agents import Agent, Runner

from nullrun import init, protect

init(api_key="nr_live_...")


@protect
def ask(prompt: str) -> str:
    agent = Agent(
        name="assistant",
        instructions="Answer in one sentence.",
    )
    result = Runner.run_sync(agent, prompt)
    return result.final_output


print(ask("What is the capital of France?"))

@protect tracks every tool call the agent makes and halts the run if the workflow exceeds budget, hits a sensitive tool, or is rate-limited by the policy. Loop detection is not part of the shipped gate surface — it lives in aggregate_policies() as an enum arm but is not wired into a dedicated detection path.
