Finding Cross-Site Request Forgery (CSRF) vulnerabilities in web applications by mapping state-changing actions, checking browser-automatic credential use, evaluating CSRF tokens, SameSite cookies, Origin/Referer defenses, and building safe browser-based proof-of-concept requests for authorized testing.

From the source SKILL.md

This skill focuses on detecting Cross-Site Request Forgery (CSRF) in authorized web application assessments. CSRF exists when a logged-in user's browser can be induced by another site to send a state-changing request that the user did not intend, and the target server accepts the request because browser-held credentials such as cookies or HTTP authentication are automatically attached.
