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

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.

Ask the owner of the distribution (the one who released it first, or the one who is designated in x_authority) to give you a (co-)maintainer's permission.

Error:

• HTML::Element
• HTML::Entities
• Mail::Cap

Fix the version numbers so that version::is_lax($version) returns true.

Error:

• lib/Font/AFM.pm: HASH(0x5609d421abc0)

Split the distribution, or fix the version numbers to make them consistent (use the highest version number to avoid version downgrade).

Error: 0.05,1.01,1.03,1.04,1.10,1.11,1.15,1.18,3.05

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