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"

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. Blocks that are calls to builtin iteration methods (e.g. `ary.map{...}) also add one, others are ignored.

Wrap expressions with varying precedence with parentheses to avoid ambiguity. Open
attributes && attributes.key?(sym.to_s) || super(sym, *args, &block)
- Read upRead up
- Exclude checks
Looks for expressions containing multiple binary operators
where precedence is ambiguous due to lack of parentheses. For example,
in 1 + 2 * 3
, the multiplication will happen before the addition, but
lexically it appears that the addition will happen first.
The cop does not consider unary operators (ie. !a
or -b
) or comparison
operators (ie. a =~ b
) because those are not ambiguous.
NOTE: Ranges are handled by Lint/AmbiguousRange
.
Example:
# bad
a + b * c
a || b && c
a ** b + c
# good (different precedence)
a + (b * c)
a || (b && c)
(a ** b) + c
# good (same precedence)
a + b + c
a * b / c % d
Call super
to initialize state of the parent class. Open
def initialize(*_args)
end
- Read upRead up
- Exclude checks
Checks for the presence of constructors and lifecycle callbacks
without calls to super
.
This cop does not consider method_missing
(and respond_to_missing?
)
because in some cases it makes sense to overtake what is considered a
missing method. In other cases, the theoretical ideal handling could be
challenging or verbose for no actual gain.
Autocorrection is not supported because the position of super
cannot be
determined automatically.
Object
and BasicObject
are allowed by this cop because of their
stateless nature. However, sometimes you might want to allow other parent
classes from this cop, for example in the case of an abstract class that is
not meant to be called with super
. In those cases, you can use the
AllowedParentClasses
option to specify which classes should be allowed
in addition to Object
and BasicObject
.
Example:
# bad
class Employee < Person
def initialize(name, salary)
@salary = salary
end
end
# good
class Employee < Person
def initialize(name, salary)
super(name)
@salary = salary
end
end
# bad
Employee = Class.new(Person) do
def initialize(name, salary)
@salary = salary
end
end
# good
Employee = Class.new(Person) do
def initialize(name, salary)
super(name)
@salary = salary
end
end
# bad
class Parent
def self.inherited(base)
do_something
end
end
# good
class Parent
def self.inherited(base)
super
do_something
end
end
# good
class ClassWithNoParent
def initialize
do_something

Example: AllowedParentClasses: [MyAbstractClass]
# good
class MyConcreteClass < MyAbstractClass
def initialize

Requires a gemspec to have rubygems_mfa_required
metadata set.
This setting tells RubyGems that MFA (Multi-Factor Authentication) is required for accounts to be able perform privileged operations, such as (see RubyGems' documentation for the full list of privileged operations):
gem push
gem yank
gem owner --add/remove
- adding or removing owners using gem ownership page
This helps make your gem more secure, as users can be more confident that gem updates were pushed by maintainers.
