95 / 100 · Low risk

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

Use to query an OpenCTI instance (is this IOC known, which entities, reports or campaigns exist for an actor) or push intel into it (indicators, observables, labels, TLP markings, relationships, STIX 2.1 import). Two-way. Invoked by /ip-investigation and friends to check the knowledge base, and by analytical skills publishing findings. Reads $OPENCTI_URL and $OPENCTI_TOKEN.

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-opencti' ] || [ -L ~/.agents/skills/'lookup-opencti' ]; then echo 'A skill folder named lookup-opencti 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 "$d" checkout --quiet 'eef29d09b60b9abb8fb2097a7e53852b0e92e86b' -- 'skills/lookup-opencti' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/lookup-opencti' ~/.agents/skills/'lookup-opencti' && 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-opencti' ~/.claude/skills/'lookup-opencti' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
