Cookstyle 6.7 released with 2 new Chef cops!

Hey folks,

Another week another Cookstyle release. This release includes an important new cop for migrating to Chef Infra 16 as well as a new RuboCop engine full of bug fixes.

Two New Cops


The ChefDeprecations/ResourceUsesOnlyResourceName cop detects custom resources / LWRPs that define a resource_name without also using provides. Starting with Chef Infra Client 16, using resource_name without also using provides will result in resource failures. Use provides to change the name of the resource instead and omit resource_name entirely if it matches the name Chef Infra Client automatically assigns based on COOKBOOKNAME_FILENAME.

Enabled by default: True

Autocorrects: Yes


The Lint/DeprecatedOpenSSLConstant cop detects an upcoming deprecation in Ruby 3.0 that impacts the usage of OpenSSL constants. This deprecation is incredibly uncommon in Chef Infra cookbooks, but we wanted to make sure that any occurrences were corrected before Ruby 3.0 ships next year.

Enabled by default: True

Autocorrects: Yes

RuboCop 0.85

The RuboCop engine that powers Cookstyle has been upgraded from 0.83 to 0.85. This new release resolves several issues that impacted detection and correction of code in cookbooks.

Other Improvements

  • The Naming/AccessorMethodName cop has been disabled. This cop did not significantly improve cookbook code and could not be autocorrected.
  • The ChefModernize/IncludingMixinShelloutInResources cop now detects and corrects occurences in legacy HWRP resources.
