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.
|no mymeta files||
This distribution contains MYMETA.* files which should be used only locally. This metric should be integrated into 'no_generated_files' eventually, but as MYMETA.* files are recent inventions, you might need to take special care if MANIFEST.SKIP exists in your distribution. Hence this metric.
Update MANIFEST.SKIP to exclude MYMETA files. If you are lazy, add "#!install_default" in your MANIFEST.SKIP and update your ExtUtils::Manifest if necessary, then some of the most common files will be excluded.
|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.
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.
|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.
|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.
