    ```python tools.py theme={null}
    from agno.agent import Agent
    from agno.models.anthropic import Claude
    from agno.tools.hackernews import HackerNewsTools

    agent = Agent(
        model=Claude(id="claude-sonnet-4-5"),
        tools=[HackerNewsTools()],
        instructions="Write a report on the topic.",
        markdown=True,
    )

    agent.print_response("Trending AI startups on Hacker News", stream=True)
    ```
