As a service owner, I would like to be notified every time a user enables one of my skills. There's considerably more nuance, in theory, but the two major areas where this helps us are: -We can take whatever account creation steps necessary in advance of a user's first invocation, so everything is ready to go when they launch a skill. -We can keep much better metrics around usage/engagement vs. install base This would likely constitute a change to the standard alexa request interface, since a request of this type would require no response, isn't the start of a session, an intent, nor the end of a session. To make sure that there are no issues with backwards incompatibility, we propose that one or more of the following mitigation solutions be implemented: 1. Allow this feature to be a toggle, defaulted to false, in the skill definition in the Amazon Developer Portal. 2. Start enabling this only for skills created (or updated) after a certain date. 3. Send the request as an optional built-in intent, just like AMAZON.Repeat, etc In addition to the above change, a similarly implemented notification of a skill being disabled would also be helpful.
