This cop checks that the ABC size of methods is not higher than the
configured maximum. The ABC size is based on assignments, branches
(method calls), and conditions. See http://c2.com/cgi/wiki?AbcMetric

Cognitive Complexity
Cognitive Complexity is a measure of how difficult a unit of code is to intuitively understand. Unlike Cyclomatic Complexity, which determines how difficult your code will be to test, Cognitive Complexity tells you how difficult your code will be to read and comprehend.
A method's cognitive complexity is based on a few simple rules:
Code is not considered more complex when it uses shorthand that the language provides for collapsing multiple statements into one
Code is considered more complex for each "break in the linear flow of the code"
Code is considered more complex when "flow breaking structures are nested"

This cop checks for operators, variables and literals used
in void context.
Example:
# bad
def some_method
some_num * 10
do_something
end
Example:
# bad
def some_method(some_var)
some_var
do_something
end
Example:
# good
def some_method
do_something
some_num * 10
end
Example:
# good
def some_method(some_var)
do_something
some_var
end
This cop checks for unused block arguments.
Example:
# bad
do_something do |used, unused|
puts used
end
do_something do |bar|
puts :foo
end
define_method(:foo) do |bar|
puts :baz
end
Example:
#good
do_something do |used, _unused|
puts used
end
do_something do
puts :foo
end
define_method(:foo) do |_bar|
puts :baz
end
This cop checks for every useless assignment to local variable in every
scope.
The basic idea for this cop was from the warning of ruby -cw:
assigned but unused variable - foo
Currently this cop has advanced logic that detects unreferenced
reassignments and properly handles varied cases such as branch, loop,
rescue, ensure, etc.
