Kwalitee Issues


Add a Changelog (best named 'Changes') to the distribution. It should list at least major changes implemented in newer versions.


Add tests!


Run a proper command ("make manifest" or "./Build manifest", maybe with a force option), or use a distribution builder to generate the MANIFEST. Or update MANIFEST manually.


  • MANIFEST (26) does not match dist (25):
  • Missing in Dist: AI-ExpertSystem-Advanced-0.02.tar.gz


List all used modules in META.yml requires


  • Term::UI


Add 'use strict' (or its equivalents) to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules are strictly written.

Error: AI::ExpertSystem::Advanced::Dictionary, AI::ExpertSystem::Advanced::Viewer::Base


Split the distribution, or fix the version numbers to make them consistent (use the highest version number to avoid version downgrade).

Error: 0.01,0.02,0.03


Add a META.json to the distribution. Your buildtool should be able to autogenerate it.


Add tests or move to the t/ directory!


If you are using Build.PL define the {requires}{perl} = VERSION field. If you are using MakeMaker (Makefile.PL) you should upgrade ExtUtils::MakeMaker to 6.48 and use MIN_PERL_VERSION parameter. Perl::MinimumVersion can help you determine which version of Perl your module needs.


Add 'use warnings' (or its equivalents) to all modules (this will require perl > 5.6), or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.

Error: AI::ExpertSystem::Advanced::Dictionary, AI::ExpertSystem::Advanced::Viewer::Base


This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.


Add all modules contained in this distribution to the META.yml field 'provides'. Module::Build or Dist::Zilla::Plugin::MetaProvides do this automatically for you.
