The CORS Policy Validator skill provides automated assistance for implementing and auditing Cross-Origin Resource Sharing (CORS) policies within the Security Fundamentals domain. It helps developers prevent unauthorized cross-domain access and data leaks by offering step-by-step guidance, generating production-ready configurations, and validating outputs against common security standards. This skill is essential for developers building secure APIs and frontend applications that interact with multiple origins, ensuring that authentication and resource sharing are handled without exposing the application to common vulnerabilities.
