update_fn

Update a function’s name and optionally set its docstring. Can be used either as a decorator with keyword arguments or as a direct function. Args: func: The function to update (optional). If provided, updates are applied directly. If not provided, returns a decorator. name: The new name for the function (optional). If provided, must not be empty. description: Optional docstring for the function Example:

​
As a function:

def my_fn(x): return x updated_fn = update_fn(my_fn, name=‘hello_there’)

​
As a decorator with name:

@update_fn(name=‘hello_there’) def my_fn(x): return x

​
As a decorator with name and description:

@update_fn(name=‘hello_there’, description=‘Says hello’) def my_fn(x): return x

​
As a decorator with no arguments:

@update_fn() def my_fn(x): return x

​
Works with async functions too:

@update_fn(name=‘async_hello’) async def my_async_fn(x): return x

wrap_tool_errors

Pydantic AI doesn’t catch errors except for ModelRetry, so we need to make sure we catch them ourselves and raise a ModelRetry instead.
