Any python function can be used as a tool by an Agent. We highly recommend creating functions specific to your workflow and adding them to your Agents.For example, here’s how to use a get_top_hackernews_stories function as a tool:

Args: num_stories (int): Number of stories to return. Defaults to 10. Returns: str: JSON string of top stories. """ # Fetch top story IDs response = httpx.get('https://hacker-news.firebaseio.com/v0/topstories.json') story_ids = response.json() # Fetch story details stories = [] for story_id in story_ids[:num_stories]: story_response = httpx.get(f'https://hacker-news.firebaseio.com/v0/item/{story_id}.json') story = story_response.json() if "text" in story: story.pop("text", None) stories.append(story) return json.dumps(stories)agent = Agent(tools=[get_top_hackernews_stories], show_tool_calls=True, markdown=True)agent.print_response("Summarize the top 5 stories on hackernews?", stream=True)
