🧰 The Tool Class

Tools are actions or capabilities that an agent can perform.

from nalona import Tool

def get_weather(city: str):
    """Fetches the current weather for a given city."""
    # Implementation...
    return weather_data

weather_tool = Tool(
    func=get_weather,
    description="Gets the current weather for a specified city.",
    params={'city': {'description': 'The city to check weather for', 'type': 'str', 'default': 'unknown'}}
)

Key Attributes

Attribute	Description
