Add a META.json to the distribution. Your buildtool should be able to autogenerate it.

If you use Mac OS X, set COPYFILE_DISABLE (for OS 10.5 and better) or COPY_EXTENDED_ATTRIBUTES_DISABLE (for OS 10.4) environmental variable to true to exclude dot underscore files from a distribution.

Add 'use warnings' (or its equivalents) to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.

Error: PadWalker

Add all modules contained in this distribution to the META.yml field 'provides'. Module::Build or Dist::Zilla::Plugin::MetaProvides do this automatically for you.

Add a 'repository' resource to the META.yml via 'meta_add' accessor (for Module::Build) or META_ADD parameter (for ExtUtils::MakeMaker).

This is not a critical issue. Currently mainly informative for the CPANTS authors. It might be removed later.
