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

By openai/codex-security (GitHub) · security · 11,339 stars · scanned at commit 884b7b6

Review agent skills before installation or use. Use when a user or security team wants to check a skill file, bundle, or collection for unsafe instructions, scripts, permissions, or external dependencies.

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/'check-skills' ] || [ -L ~/.agents/skills/'check-skills' ]; then echo 'A skill folder named check-skills already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/openai/codex-security' "$d" && git -C "$d" checkout --quiet '884b7b657a1d8738c50d1967d309cab37c9380a7' -- 'plugins/codex-security/skills/check-skills' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/codex-security/skills/check-skills' ~/.agents/skills/'check-skills' && 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/'check-skills' ~/.claude/skills/'check-skills' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
