troubleshooting-authentication

The skill content is broadly coherent with its stated purpose of authentication troubleshooting for MSAL, JWT, and Entra ID. It presents a reasonable frontend-backend authentication pattern, sensible token audience handling, and a dev/prod credential strategy. There are minor areas to tighten, such as explicit token revocation/refresh handling, stronger guidance on secret rotation for development, and explicit security checks to prevent token leakage in logs. Overall, the footprint is benign and proportionate to its stated debugging-focused purpose.
