lookup-urlscan

95 / 100 · Low risk

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

By Liberty91LTD/cti-skills (GitHub) · security · 38 stars · scanned at commit eef29d0

Use when you need to submit a URL for live scanning via URLScan.io and retrieve results, or search existing scans for a domain. Returns verdict, final URL after redirects, resolved IP, contacted domains/IPs, and screenshot URL. Commonly invoked by /url-investigation and /domain-investigation.

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/'lookup-urlscan' ] || [ -L ~/.agents/skills/'lookup-urlscan' ]; then echo 'A skill folder named lookup-urlscan already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/Liberty91LTD/cti-skills' "$d" && git -C "$d" checkout --quiet 'eef29d09b60b9abb8fb2097a7e53852b0e92e86b' -- 'skills/lookup-urlscan' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/lookup-urlscan' ~/.agents/skills/'lookup-urlscan' && 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/'lookup-urlscan' ~/.claude/skills/'lookup-urlscan' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
