[matt-cook]

Can be checked (and possibly partially fixed) with Coder module: https://www.drupal.org/project/coder

Online tool: http://pareview.sh/

Overall module development details here: https://www.drupal.org/module-development

Possibly https://www.drupal.org/project/profiler_builder could be helpful.

@matt-schuh you should create an account on https://www.drupal.org/ (if you don't have one) and I'll add you as a maintainer for the public project: https://www.drupal.org/sandbox/zebradog/2463261 .As we get updates polished we can push into that project.
