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

Use the prompt() method from ExtUtils::MakeMaker/Module::Build.

Define the license if you are using in Build.PL. If you are using MakeMaker (Makefile.PL) you should upgrade to ExtUtils::MakeMaker version 6.31.

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: Tangram, Tangram::AbstractStorage, Tangram::Array, Tangram::Coll, Tangram::Cursor, Tangram::Expr, Tangram::Hash, Tangram::Ref, Tangram::Scalar, Tangram::Schema, Tangram::Schema, Tangram::Set, Tangram::Type

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

List all modules used in the Makefile.PL/Build.PL in META.yml configure_requires

Error:
