How does this handle user registration validation?

It includes templates for 'OnAttributeCollectionSubmit' which allow you to validate user input, show errors, or block registration based on custom criteria.

Can I use this skill to add data to a user's JWT token?

Yes, it provides patterns for the 'OnTokenIssuanceStart' event, allowing you to fetch external data and inject it as custom claims into the issued token.

What is the primary purpose of this Entra ID skill?

The skill helps developers implement custom logic for Microsoft Entra ID authentication flows, specifically using the .NET Azure Functions extension for authentication events.

Does this skill support custom MFA delivery?

Yes, it supports the 'OnOtpSend' event, enabling you to route one-time passwords through your own SMS, email, or push notification providers instead of the default Entra ID service.

Implements custom Microsoft Entra ID authentication extensions using Azure Functions and .NET for advanced identity workflows.

This skill provides specialized implementation patterns for the Microsoft Entra ID Authentication Events SDK, enabling developers to extend standard identity flows with custom logic. It facilitates the creation of Azure Functions that can inject custom claims into tokens (token enrichment), customize the user attribute collection experience, validate or modify user-submitted data during registration, and implement bespoke OTP delivery mechanisms. By grounding Claude in the specific triggers and response types of the WebJobs AuthenticationEvents extension, it ensures the generation of production-grade code for complex identity requirements.
