Resource Schema Information and Validation

You can use the Alexa Skills Kit Command Line Interface (ASK CLI) or the Alexa Skill Management API (SMAPI) to manage your Alexa skill. Your Alexa skill is represented by a skill manifest which conforms to a schema. When you call a CLI or SMAPI command that requires a skill manifest as an argument, errors can occur if your schema is incorrect.

You can also manage your skill by using the ASK SDKs and Toolkits. When you work with your skill locally, it is represented as a skill package which conforms to a directory structure. When you try to work with a skill package, errors can occur if your directory structure is incorrect.

Schema information is specific to your skill. For example, if you participate in a beta program, the manifest for your skill might require data specific to the beta program, while the manifest for a similar skill does not. Before you call a CLI or SMAPI command, or work with a skill package locally, you can get information about the schema or directory structure that your skill requires. You can use this information to validate your schema or directory structure before errors occur.

This document describes the resourceSchema API. You can also get schema and skill package information by using the get-resource-schema CLI command.
