Overview

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

Positional arguments are unnamed and order-dependent, which makes a long list of them especially prone to primitive obsession. Required (arg) and optional (optarg) parameters are counted; *rest and &block are not.

Examples:

Max: 2

# bad
def move(x, y, z)
end

# good
def move(point)
end
