exposure

80 / 100 · Low risk

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

Grade a domain's external exposure A-F with OpenOSINT (email authentication, TLS, domain registration, security headers). Use when the user asks for an exposure check, security posture, email-spoofing or DMARC/SPF check, or "how exposed is this domain". No API key needed.

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/'exposure' ] || [ -L ~/.agents/skills/'exposure' ]; then echo 'A skill folder named exposure already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/OpenOSINT/OpenOSINT' "$d" && git -C "$d" checkout --quiet '7ee03c48cf1e92525242529a7aab4530f0f0b767' -- 'skills/exposure' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/exposure' ~/.agents/skills/'exposure' && 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/'exposure' ~/.claude/skills/'exposure' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
