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

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: Catalyst, Catalyst::Action, Catalyst::ActionChain, Catalyst::ActionContainer, Catalyst::AttrContainer, Catalyst::Base, Catalyst::Component, Catalyst::Controller, Catalyst::DispatchType, Catalyst::DispatchType::Chained, Catalyst::DispatchType::Default, Catalyst::DispatchType::Index, Catalyst::DispatchType::Path, Catalyst::DispatchType::Regex, Catalyst::Dispatcher, Catalyst::Engine, Catalyst::Engine::CGI, Catalyst::Engine::FastCGI, Catalyst::Engine::HTTP, Catalyst::Exception, Catalyst::Log, Catalyst::Manual, Catalyst::Model, Catalyst::Request, Catalyst::Request::Upload, Catalyst::Response, Catalyst::Utils, Catalyst::View

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.

Add SECURITY(.pod|md). See Software::Security::Policy.

Add SECURITY(.pod|md) and add a contact address. See Software::Security::Policy.

Add CONTRIBUTING(.pod|md). See https://docs.github.com/en/communities/setting-up-your-project-for-healthy-contributions/setting-guidelines-for-repository-contributors.
