@croaky guard:jasmine is the rake task included in the 'guard-jasmine` gem. According to the README: "Guard::Jasmine provides a Rake task wrapper around the Thor command line utility. " This is explained in the "Guard::Jasmine Outside of Guard" section: https://github.com/netzpirat/guard-jasmine#guardjasmine-outside-of-guard

I haven't actually been using Guard to automatically run specs when the file is changed, it was just the easiest way to run our jasmine specs headlessly without evergreen and I wanted to automatically run the jasmine specs as part of the default rake task.

If that doesn't make sense or sounds off, just let me know!
