This distribution doesn't extract well due to several reasons such as unsupported archive type (CPANTS only supports tar.gz, tgz and zip archives), file permissions, broken links, invalid filenames, and so on. Most of other kwalitee metrics should be ignored.
Pack the distribution with a proper command such as "make dist" and "./Build dist", or use a distribution builder such as Dist::Zilla, Dist::Milla, Minilla. You might also need to set some options or environmental variables to ensure your archiver work portably.
|manifest matches dist||
MANIFEST does not match the contents of this distribution.
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.
|metayml 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.
|metayml has provides||
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 does this automatically for you.
|has separate license file||
