System Documentation

What problem does it solve?

This Skill removes the complexity of launching and repairing custom domains for web apps by coordinating DNS, hosting platform routing, authentication provider settings, and browser security policies.

Core Features & Use Cases

  • End-to-End Setup: Add a new custom domain, map it to the correct hosting target, and align SSL provisioning.
  • Domain Health Checks: Diagnose whether DNS, certificates, frontend routing, backend CORS, and auth allowlists are configured correctly.
  • Targeted Fixes: Resolve common production issues such as login loops, CORS failures, SSL mismatches, and domain verification problems.
  • Use Case: A team ships a new branded domain and needs the app, backend, and auth provider updated so users can sign in reliably without browser or API errors.

Quick Start

Ask the assistant to check, set up, or fix your custom domain by providing the domain name and the desired command: setup, check, or fix.
