BACKGROUND

A “skill” is a device capability. Amazon's ALEXA, a so-called intelligent personal assistant capable of voice interaction, provides examples in which a user can enable and disable skills, using the ALEXA application (app) or a web browser, as one would install and remove apps on a mobile device. Skills can be called up using manual user-interface (UI) devices, such as a keyboard or mouse, or can be called up using voice commands. People and institutions are rapidly developing skills for accomplishing myriad tasks. There nevertheless remains a demand for skill development.
