Example:

import asyncio
from langchain.agents import create_agent
from langchain_aws.tools import create_browser_toolkit

async def main():
    # Create and setup the browser toolkit
    toolkit, browser_tools = create_browser_toolkit(region="us-west-2")

    # Create a ReAct agent using the browser tools
    agent = create_agent(
        "bedrock_converse:us.anthropic.claude-haiku-4-5-20251001-v1:0",
        tools=browser_tools
    )

    # Create runnable config with thread ID
    config = {
        "configurable": {
            "thread_id": "session123"
        }
    }

    # Invoke the agent with a specific task using thread ID
    result = await agent.ainvoke(
        "Navigate to https://www.example.com and tell me the main heading "
        "on the page.",
        config=config
    )

    # Clean up browser resources when done
    await toolkit.cleanup()

    return result

# Run the example
asyncio.run(main())
