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.
This distribution doesn't contain either a file called 'test.pl' or a directory called 't'. This indicates that it doesn't contain even the most basic test-suite. This is really BAD!
|buildtool not executable||
The build tool (Build.PL/Makefile.PL) is executable. This is bad because you should specify which perl you want to use while installing.
Change the permissions of Build.PL/Makefile.PL to not-executable.
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.
|has tests in t dir||
This distribution contains either a file called 'test.pl' (the old test file) or is missing a directory called 't'. This indicates that it uses the old test mechanism or it has no test-suite.
Add tests or move tests.pl to the t/ directory!
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.
