Triggers on requests like "security scan", "vulnerability check", "audit security", "find vulnerabilities", "/yds-vulnerability-scan", or when asked for an offensive security review of the codebase. Does NOT modif.

Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
