There is no global best practice for this. Your wiki can move them into the main namespace if it wishes or it can leave them in the template namespace if that is what is preferred. There are certainly types of templates that essentially copy-past content such as navboxes, hatnotes, etc.; so these skill templates could be considered similar to those. What I would consider main tradeoff between the namespaces is this: having the skill pages available as regular content pages versus being able to use the "regular" transclusion syntax.
