Creating an Alexa skill might seem daunting, but it’s surprisingly straightforward. This guide provides a comprehensive walkthrough of the process, from initial setup to publishing your skill. Whether you’re aiming for a simple fact skill or a more complex application, this guide will equip you with the foundational knowledge to get started.
Setting Up Your Alexa Skill in the Developer Portal
The first step is creating an account with Amazon Developer, a free and easy process. The developer console is user-friendly, guiding you through creating a new skill with a simple checklist. You’ll need to choose an Invocation Name, the name users will say to activate your skill. Keep it simple and memorable, often aligning with the skill’s name.
Next, you’ll define the Interaction Model using the Skill Builder, a tool similar to Microsoft’s luis.ai. Here, you’ll create Intents, representing actions users can request, and add sample utterances, phrases users might say to trigger those Intents. For example, for a fact skill, an intent might be “GetNewFact” with utterances like “tell me a fact” or “give me some trivia.” After defining your model, save and build it – the build time is usually quite short.

Setting Up a Lambda Function Using Amazon Web Services
The next stage involves setting up a Lambda function in Amazon Web Services (AWS) to handle your skill’s logic. While AWS experience is helpful, it’s not mandatory for basic skills. Choose the Alexa Skills Kit blueprint, set the Alexa Skills Kit as a trigger, and configure a Lambda role. Note that the trigger is set up after creating the function.
Connecting Your Voice User Interface to Your Lambda Function
This step involves linking your AWS Lambda function with the Voice User Interface in the developer console. This simply requires filling out a form to connect the two components. For a basic Fact skill, this connection is straightforward. More complex skills might require additional configuration.

Testing Your Alexa Skill
Thorough testing ensures your skill functions as intended. The Alexa developer console provides a voice simulator and a service simulator for testing. You can also create test events directly within AWS Lambda. For basic skills, testing within the Lambda function portal is sufficient. More comprehensive testing can be performed using tools like Echosim.io or unit testing frameworks.
Customizing Your Alexa Skill
This is where you personalize your skill. For a fact skill, replace the default facts with your own. Aim for at least 25 facts to provide a good user experience. You can customize responses, help messages, and other aspects of the skill’s behavior by modifying the index.js file within the skill’s code. This file contains the core logic for your skill and allows you to tailor it to your specific needs.
Publishing Your Alexa Skill
The final step is publishing your skill to the Alexa Skills Store. This involves providing information about your skill, such as a description, example phrases, icons, and privacy details. Ensure your skill description is clear and concise, highlighting its key features and functionality. Use the sample utterances you defined earlier as example phrases to guide users on how to interact with your skill. After completing the necessary information, submit your skill for certification. The review process typically takes around 7 days.
