This cop checks that the cyclomatic complexity of methods is not higher than the configured maximum. The cyclomatic complexity is the number of linearly independent paths through a method. The algorithm counts decision points and adds one.
An if statement (or unless or ?:) increases the complexity by one. An else branch does not, since it doesn't add a decision point. The && operator (or keyword and) can be converted to a nested if statement, and ||/or is shorthand for a sequence of ifs, so they also add one. Loops can be said to have an exit condition, so they add one.

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"

Useless private
access modifier. Open
private
- Read upRead up
- Exclude checks
This cop checks for redundant access modifiers, including those with no
code, those which are repeated, and leading public
modifiers in a
class or module body. Conditionally-defined methods are considered as
always being defined, and thus access modifiers guarding such methods
are not redundant.
Example:
class Foo
public # this is redundant (default access is public)
def method
end
private # this is not redundant (a method is defined)
def method2
end
private # this is redundant (no following methods are defined)
end
Example:
class Foo
# The following is not redundant (conditionally defined methods are
# considered as always defining a method)
private
if condition?
def method
end
end
protected # this is not redundant (method is defined)
define_method(:method2) do
end
protected # this is redundant (repeated from previous modifier)
[1,2,3].each do |i|
define_method("foo#{i}") do
end
end
# The following is redundant (methods defined on the class'
# singleton class are not affected by the public modifier)
public
def self.method3
end
end
Example:
# Lint/UselessAccessModifier:
# ContextCreatingMethods:
# - concerning
require 'active_support/concern'
class Foo
concerning :Bar do
def some_public_method
end
private
def some_private_method
end
end
# this is not redundant because `concerning` created its own context
private
def some_other_private_method
end
end
Example:
# Lint/UselessAccessModifier:
# MethodCreatingMethods:
# - delegate
require 'active_support/core_ext/module/delegation'
class Foo
# this is not redundant because `delegate` creates methods
private
delegate :method_a, to: :method_b
