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

Add 'use warnings' (or its equivalents) 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.

Error: Language::MinCaml, Language::MinCaml::Code, Language::MinCaml::Evaluator, Language::MinCaml::Lexer, Language::MinCaml::Node, Language::MinCaml::Parser, Language::MinCaml::Token, Language::MinCaml::Type, Language::MinCaml::TypeInferrer, Language::MinCaml::Util

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

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).
