This distribution does not have a license defined in the documentation or in a file called LICENSE

Add a section called "LICENSE" to the documentation, or add a file named LICENSE to the distribution.

Does not have license information in any of its source files

Add =head1 LICENSE and the text of the license to the main module in your code.

This distribution does not 'use strict;' (or its equivalents) in all of its modules. Note that this is not about the actual strictness of the modules. It's bad if nobody can tell whether the modules are strictly written or not, without reading the source code of your favorite clever module that actually enforces strictness. In other words, it's bad if someone feels the need to add 'use strict' to your modules.

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.

This distribution uses a module or a dist that's not listed as a prerequisite.

List all used modules in META.yml requires

This distribution does not declare the minimum perl version in META.yml.

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.

This distribution does not have a license defined in META.yml.

Define the license if you are using in Build.PL. If you are using MakeMaker (Makefile.PL) you should upgrade to ExtUtils::MakeMaker version 6.31.

Does not have license information in any of its source files, or the information is not recognized by Software::License

Add =head1 LICENSE and/or the proper text of the well-known license to the main module in your code.

This distribution does not 'use warnings;' (or its equivalents) in all of its modules. Note that this is not about that your modules actually warn when something bad happens. It's bad if nobody can tell if a module warns or not, without reading the source code of your favorite module that actually enforces warnings. In other words, it's bad if someone feels the need to add 'use warnings' to your modules.

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.

This distribution is not required by another distribution by another author.

Convince / force / bribe another CPAN author to use this distribution.

This distribution does not have a list of provided modules defined in META.yml.

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.

This distribution does not have a link to a repository in META.yml.

Add a 'repository' resource to the META.yml via 'meta_add' accessor (for Module::Build) or META_ADD parameter (for ExtUtils::MakeMaker).

This distribution does not have a LICENSE or LICENCE file in its root directory.

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