# ---------------------------------------------------------------------------
# Create Agents
# ---------------------------------------------------------------------------

# Example 1: Read and write files (default)
agent = Agent(
    model=OpenAIResponses(id="gpt-5.5"),
    tools=[LocalFileSystemTools(target_directory="tmp/local_file_system")],
    markdown=True,
)

# Example 2: Write-only mode (disable read_file)
write_only_agent = Agent(
    model=OpenAIResponses(id="gpt-5.5"),
    tools=[
        LocalFileSystemTools(
            target_directory="tmp/local_file_system", enable_read_file=False
        )
    ],
    markdown=True,
)

# ---------------------------------------------------------------------------
# Run Agent
# ---------------------------------------------------------------------------
if __name__ == "__main__":
    # Write a file and then read it back
    agent.print_response(
        "Write a short poem about programming to a file named poem.txt, then read it back to me.",
        stream=True,
    )

    # Write-only agent: generate code and save it to disk
    # write_only_agent.print_response(
    #     "Write a Python function that calculates fibonacci numbers and save it to tmp/local_file_system/fib.py",
    #     stream=True,
    # )

Run the Example

1. Set up your virtual environment

   Mac

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

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

   uv pip install -U agno openai
   
3. Export your OpenAI API key

   Mac/Linux

   export OPENAI_API_KEY="your_openai_api_key_here"
   

   $Env:OPENAI_API_KEY="your_openai_api_key_here"
   
4. Run the example

   Save the code above as local_file_system_tools.py, then run:

   python local_file_system_tools.py
