Creating your own tools

Write custom tool functions and use the `@tool` decorator to modify tool behavior.

In most production cases, you will need to write your own tools.

The rule is simple:

  • Any Python function can be used as a tool by an Agent.
  • Use the @tool decorator to modify what happens before and after this tool is called.

There are two main ways to create tools in Agno:

  1. Create a Python function (optionally using the @tool decorator)
  2. Create a Toolkit
