Paul Allen's AI group built a voice search for Alexa skills, but Amazon rejected it

Amazon's digital brain Alexa is very skillful, now at more than 12,000 third-party capabilities, but it can sometimes be difficult to wade through them all and discover new skills, and the platform lacks a central voice search to help users find the right skill for a particular task. Paul Allen's Allen Institute for Artificial Intelligence wanted to fill that void, and it built a voice-activated search for Alexa skills. But one problem: Amazon said no. Here is the answer the Allen Institute team got: "Thank you for the recent submission of your skill, 'Skill Search'. Unfortunately, your skill has not been published on Amazon Alexa. We don't allow skills that recommend skills to customers at this time. We will contact you if this feature becomes available."
