Feature request: support class in tool registration #3816
Description
Google ADK's tool calling mechanism is extremely restrictive and suffers from poor usability.
For example, let's say I implement 6 custom functions using pandas to manipulate DataFrames, intended to be used identically across multiple agents. In this scenario, since ADK only accepts individual functions or agents, I am forced to repetitively register func1 through func6 for every single agent. This design is highly inefficient and user-unfriendly.
Agno addresses this by providing a Toolkit class to bundle related tools. Do you have any plans to adopt a similar approach?
