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

Claude Security: scan the codebase (the whole repository or a scoped part of it), scan changes (this branch's or a pull request's diff, or one commit), or suggest patches (findings turned into targeted patch files, each verified by a panel of agents, that you apply when you choose). Use when the user asks to scan, audit or check code with Claude Security, to scan their changes with Claude Security, or to fix or patch Claude Security findings.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'claude-security' ] || [ -L ~/.agents/skills/'claude-security' ]; then echo 'A skill folder named claude-security already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/anthropics/claude-plugins-official' "$d" && git -C "$d" checkout --quiet 'dceb15d50832e6adf380bedc26dde03d251324b9' -- 'plugins/claude-security/skills/claude-security' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/claude-security/skills/claude-security' ~/.agents/skills/'claude-security' && rm -rf "$d"; fi

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/'claude-security' ~/.claude/skills/'claude-security' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
