The distribution hasn't got a Changelog (named something like m/^chang(es?|log)|history$/i. A Changelog helps people decide if they want to upgrade to a new version.
Add a Changelog (best named 'Changes') to the distribution. It should list at least major changes implemented in newer versions.
|no broken module install||
This distribution uses an obsolete version of Module::Install. Versions of Module::Install prior to 0.61 might not work on some systems at all. Additionally if your Makefile.PL uses the 'auto_install()' feature, you need at least version 0.64. Also, 1.04 is known to be broken.
Upgrade the bundled version of Module::Install to the most current release. Alternatively, you can switch to another build system / installer that does not suffer from this problem. (ExtUtils::MakeMaker, Module::Build both of which have their own set of problems.)
|meta yml declares perl version||
This distribution does not declare the minimum perl version in META.yml.
This distribution is not required by another distribution by another author.
Convince / force / bribe another CPAN author to use this distribution.
These fails are not serious and don't affect your Kwalitee scores at all.
|meta yml has provides||
This distribution does not have a list of provided modules defined in META.yml.
|meta yml has repository resource||
This distribution does not have a link to a repository in META.yml.
|has separate license file||
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.
