Use when setting up, troubleshooting, managing, removing, or checking the health of an Auth0 custom authentication domain (e.g. login.example.com), OR when diagnosing an error (400/403/404/409/429) from the /custom-domains Management API — especially Free-tier 403s (credit card on file, not a plan upgrade), self-managed cert 403s, PATCH-type 400s, `operation_not_supported` on `relying_party_identifier`, and 409 domain-already-exists. Handles CNAME creation in the user's DNS provider (Cloudflare, AWS Route 53, Azure DNS automated; other registrars guided), verification polling, Multiple Custom Domains (MCD), default-domain selection, TLS policy, client-IP header, per-domain passkey relying party identifier, and domain metadata.

Generates complete, branded Auth0 Advanced Custom Universal Login (ACUL) screen implementations using the React or Vanilla JS SDK. Use when a developer asks to create, add, or modify ACUL login screens with custom branding, social login, theming, or specific authentication flows. Triggers on requests like "generate a custom login screen", "add a signup screen to my ACUL project", "customize my Auth0 Universal Login with our brand colors", "apply our theme to all ACUL screens", or any task involving Auth0 Universal Login customization with @auth0/auth0-acul-react or @auth0/auth0-acul-js.

Use when upgrading an Android app's Auth0 SDK (com.auth0.android:auth0) to the next major version. Detects the current version, checks prerequisites, and applies only the breaking changes that affect the project's real call sites. Use even if the user just says "update my Auth0 Android SDK" or "migrate to Auth0 Android v4".
Use when customizing the look of Auth0 Universal Login to match a brand — changing colors, logo, fonts, page layout, or login text. Also use when resetting branding to defaults or checking if branding is wired up end-to-end. Does not cover full custom UI screens — use acul-screen-generator for that.
