Overview

Checks that a method does not declare too many keyword arguments.

Keyword arguments are self-documenting, but a long list of them is still a sign that the related values want to be modeled as an object. Required (kwarg) and optional (kwoptarg) parameters are counted; **rest is not.

Examples:

Max: 2

# bad
def calculate_volume(width:, length:, height:)
end

# good
def calculate_volume(shape)
end
