CSRF Protection Validator

About

The CSRF Protection Validator is a specialized security skill that empowers Claude to audit web applications for Cross-Site Request Forgery risks. It systematically analyzes application endpoints, assesses the effectiveness of existing protection mechanisms like synchronizer tokens and SameSite cookie attributes, and identifies gaps in origin validation. By providing detailed reports and actionable remediation advice, this skill helps developers harden their applications against unauthorized state-changing requests and ensures comprehensive security coverage for all sensitive operations.
