ember-css-modules-stylelint 

This ember-css-modules plugin incorporates Stylelint into the CSS Modules build pipeline. You can configure it using standard .stylelintrc.js files in your repo.

Note: you'll generally want to use this plugin in concert with another, like ember-css-modules-reporter, in order to have the warnings that Stylelint produces actually go somewhere. Together, they can provide a developer experience similar to that of e.g. ember-cli-eslint, providing warnings on rebuild and generating lint tests to flag failures.
