This distribution doesn't create a directory and extracts its content into this directory. Instead, it creates more than one directories (some of which are probably system-specific hidden files/directories), or it spews its content into the current directory, making it really hard/annoying to remove the unpacked package.
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.
|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.
|package version matches dist version||
None of the package versions in this distribution matches the distribution version.
Fix the version(s).
|metayml declares perl version||
This distribution does not declare the minimum perl version in META.yml.
This distribution does not 'use warnings;' 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' 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.
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||
This distribution does not have a LICENSE or LICENCE file in its root directory.
