Fine to try. Some of what it can do is expected: a security skill usually runs scanners and checks websites.

By dreadnode/capabilities (GitHub) · security · 22 stars · scanned at commit 3ceeb34

Escalate blind SSRF to proven impact via internal service canaries, port fingerprinting, chained exploitation targeting Redis, Docker API, Jenkins, and cloud metadata, and attacker-controlled infrastructure for dangling resource claims and redirect servers. Use when blind SSRF is confirmed but you need to demonstrate CIA impact beyond 'I can reach internal hosts.'

Works with any agent that supports SKILL.md skills.

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'blind-ssrf-chains' ~/.claude/skills/'blind-ssrf-chains' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
