from langchain.agents import create_agent
from langchain_deepkeep import DeepKeepMiddleware

agent = create_agent(
    model="gpt-5.5",
    tools=[],
    middleware=[
        DeepKeepMiddleware(
            api_key=os.environ["DEEPKEEP_API_KEY"],
            base_url=os.environ["DEEPKEEP_BASE_URL"],
            pre_model="input-firewall-id",
            post_model="output-firewall-id",

    ],
)

pre_model and post_model are DeepKeep firewall IDs. Each value is sent to the matching moderation endpoint as the model field.
