Agent with Tools

Give your agent tools to interact with external services.

Give an agent tools to interact with external services. The agent uses HackerNewsTools to fetch trending stories and user details.

1. Create a Python file

   tools.py

   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)
   
2. Set up your virtual environment

   Mac

   uv venv --python 3.12
   source .venv/bin/activate
   

   uv venv --python 3.12
   .venv\Scripts\activate
   
3. Install dependencies

   uv pip install -U agno anthropic
   
4. Export your Anthropic API key

   Mac/Linux

   export ANTHROPIC_API_KEY="your_anthropic_api_key_here"
   

   $Env:ANTHROPIC_API_KEY="your_anthropic_api_key_here"
   
5. Run Agent

   python tools.py
