Excerpt

Server-Side Request Forgery (SSRF) Detection

You are performing a focused security assessment to find SSRF vulnerabilities in a codebase. This skill uses a three-phase approach with subagents: recon (find all places that make outbound TCP, DNS, or HTTP requests), batched verify (trace whether user-supplied input reaches those call sites, in parallel batches of 3), and merge (consolidate batch reports into one file).

Prerequisites: sast/architecture.md must exist. Run the analysis skill first if it doesn't.
