OpenTool provides a common potocol for AI agent tools, use them with your favorite agent framework or model.

Installation

pip install opentool-ai

Usage

Let's define a simple weather logger tool

from opentool import Tool, action, observation
from selenium import webdriver


class WeatherLogger(Tool):
  """A simple weather logger."""

    @action
    def log(self, message: str) -> None:
        """Logs a message to the log file."""

        with open("weather.txt", "a") as file:
            file.write("***\n" + message + "\n")

    @observation
    def weather(self, location: str) -> str:
        """Checks the current weather from the internet using wttr.in."""

        weather_api_url = f"http://wttr.in/{location}?format=%l:+%C+%t"
        response = requests.get(weather_api_url)
        response.raise_for_status()
        return response.text

We mark the functions to be made available to the agent as

• @action if they mutate the environment
• @observation if they are read only.

Function Calling

Use a tool with OpenAI function calling

from openai import OpenAI

client = OpenAI()

weatherlogger = WeatherLogger()
schemas = weatherlogger.json_schema()

messages = []
messages.append({"role": "system", "content": "Don't make assumptions about what values to plug into functions. Ask for clarification if a user request is ambiguous."})
messages.append({"role": "user", "content": "What is the weather in Paris?"})

headers = {
    "Content-Type": "application/json",
    "Authorization": "Bearer " + openai.api_key,
}
json_data = {"model": model, "messages": messages, "tools": schemas}
response = requests.post(
    "https://api.openai.com/v1/chat/completions",
    headers=headers,
    json=json_data,
)

assistant_message = response.json()["choices"][0]["message"]
messages.append(assistant_message)
assistant_message

{
  "role": "assistant",
  "tool_calls": [
    {
      "id": "call_RYXaDjxpUCfWmpXU7BZEYVqS",
      "type": "function",
      "function": {
        "name": "weather",
        "arguments": "{\n  \"location\": \"Paris\"}"
      }
    }
  ]
}

Then to use this action

for tool in assistant_message["tool_calls"]:
    action = weatherlogger.find_action(tool["function"]["name"])
    args = json.loads(tool["function"]["arguments"])
    resp = weatherlogger.use(action, **args)
