Deactivate intents directive depending on context
Depending on the state of the user discussion, It could be useful to be able to deactivate on the fly some intents, by sending an appropriate directive, to restrict the intents matching possibilities and make the intent selection more efficient.
For instance, if I have a skill with the following intents:
If my game have two states: ChooseGame and Playing.
It could be useful, to deactivate the ProvideGameAnswer intent when being in ChooseGame state, and to disable the two others when being in Playing state. This way, Alexa will never retrieve by accident an intent that is not possible in a given time.
