From the source SKILL.md

Static scanner for OWASP A10:2021 — Server-Side Request Forgery (SSRF) vulnerabilities. Finds all URL-fetching sinks in your codebase, traces HTTP input to those sinks, and checks for missing allowlist/blocklist guards. Flags hardcoded cloud metadata endpoint access as CRITICAL. Zero external API calls, zero dependencies beyond Python 3 stdlib.
