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.

This code sample will allow you to hear a response from Alexa when you trigger it. It is a minimal sample to get you familiarized with the Alexa Skills Kit and AWS Lambda.

This is a step-up in functionality from Hello World. It allows you to capture input from your user and demonstrates the use of Slots.

This sample will walk first-time Alexa skill developers through all the required steps involved in creating a parameter-based skill using a template called ‘Minecraft Helper’. Ask how to craft an item in the game Minecraft, and this skill will give you instructions. The skill showcases:

• Custom slot type: demonstrates using custom slot types to handle a finite set of known values
• Dialog and Session state: Handles two models, both a one-shot ask and tell model, and a multi-turn dialog model.
• Usage of ResourceBundle to handle internalization

Template for a local recommendations skill. Alexa uses the data that you provide to offer recommendations according to the user stated preferences. This Skill showcases:

• Custom slot type: demonstrates using custom slot types to handle a finite set of known values
• Dialog and Session state: Handles two models, both a one-shot ask and tell model, and a multi-turn dialog model.
• Usage of ResourceBundle to handle internalization
• Calling external APIs from the skill.

This tutorial will guide you in building a fully-featured skill. The skill features Built-In and Custom slots, as well as state management. The skill you build with this tutorial can be customized to build your own game.

This tutorial will demonstrate how to write skills for Echo Show and Echo Spot in Java using the Alexa Skills Kit (ASK) SDK v2.

This tutorial demonstrates 3 features of APL: the Pager Component, SpeakItem Command, and accessing device characteristics in the skill code.
