xss-browser-confirm
xss-browser-confirm is an Application security skill for AI agents, published by vigolium in the vigolium repository on GitHub. Skillspace rates xss-browser-confirm C (74/100) and it passed the safety scan; the rating is based on static analysis only.
Turn a suspected Cross-Site Scripting reflection or DOM sink into proof of JavaScript execution by firing a uniquely-tagged dialog in a real headless browser via the browser_probe tool — not by string-matching the response. Covers reflected, stored, and DOM-based XSS, context-aware payload crafting (HTML body, attribute, JS string, URL/href, DOM sink), light WAF/encoding evasion when a payload reflects but doesn't execute, and persisting a finding sized by real impact. Use when a parameter's value appears in the response, when a DOM sink (innerHTML, document.write, eval, location) consumes input, when CWE-79 was flagged, or when a scanner saw reflection but couldn't confirm execution.
