    Multiplies two integers and returns the result.

    This function takes two integers `a` and `b`, multiplies them, and returns
    the product. It is designed to be used as a LangChain tool that can be
    called by agents or workflows in the LangChain ecosystem.

    Parameters:
    ----------
    a : int
        The first integer to be multiplied.
    b : int
        The second integer to be multiplied.

    Returns:
    -------
    int
        The product of `a` and `b`.

    Example:
    -------
    >>> multiply_numbers(3, 4)
