Hey!
I got this running on my host, but I needed to add a php_binary config option and rework the artisan calls to use this php_binary path if it was present instead of 'php artisan' because on my shared host the cron environment doesn't seem to include paths (they recommend in their docs to use whichever explicit php bin you want via path, etc.)
If someone tried to run this locally where they have more control over the path variables in different environments they might get frustrated if their shared host doesn't have their cron environment set up that way.
Other than that, using it to update Mixpost horizon on shared A2 - works a treat.
