The SDK works on model classes rather than native Alexa JSON requests and responses. These model classes are generated using the Request, Response JSON schemas from the developer docs. The source code for the model classes can be found here.


Hello World

Sample that familiarizes you with the Alexa Skills Kit and AWS Lambda by allowing you to hear a response from Alexa when you trigger the sample.

Template for a parameter-based skill called 'Minecraft Helper'. When the user asks how to craft an item in the game Minecraft, the skill provides instructions.
