Hey, we've reviewed adding v1 support and team will be working on this when on better bandwidth. — Here's a v1 snippet which you can use:

from composio_langchain import LangchainProvider
from langchain.agents import create_agent
from langchain_openai import ChatOpenAI

openai_client = ChatOpenAI(model="gpt-5")

composio = Composio(provider=LangchainProvider(), api_key="<api-key>")

# Get All the tools
tools = composio.tools.get(user_id="default", toolkits=["GITHUB"])

# Define task
task = "Star a repo composiohq/composio on GitHub"

# Define agent
agent = create_agent(model=openai_client, tools=tools, system_prompt="intelligent composio agent")
result = agent.invoke({
    "messages": [
        {"role": "user", "content": "Star a repo composiohq/composio on GitHub"}
    ]
})
print(result)

Thanks!
