@akshatnitd @fragm3 Please check if this is the right way we are suppose to display the console services. This is still WIP. We should display all skills present in conf/os_skills/system/en Right?

[akshatnitd]

Each skill object should have meta data similar to other normal skills, so that we can represent it on the UI

I'm unsure if we should do this #1368 (comment)
