hunt-xxe skillA

hunt-xxe is agent-read markdown (skill) from galact-byte/galact-skills: 在授权渗透测试中挖掘 XML 外部实体注入（XXE）。当目标解析用户可控的 XML——SOAP、SAML、SVG、RSS/Atom、DOCX/XLSX、WSDL/XSL、含 XML 的反序列化——且可能启用了外部实体时使用。典型场景：外部实体读本地文件、SSRF 打内网、OOB 带外/报错型外带数据、XXE→反序列化链。适用目标类型 Web / REST API / SOAP。触发场景包括用户说"测下 XXE""这个 XML/SVG 接口能不能读文件""XXE 打内网/带外""SAML 里能注实体吗"。输出：XXE 触发点 + 读到的文件/带外证据的 finding（含 killed 记录）。.

The deterministic audit below grades the latest version, and the same file always earns the same grade.
