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 hunt in the organisation's own Microsoft Sentinel workspace: sweep logs for IOC hits (IP, domain, hash, URL, account), hunt ATT&CK techniques, run KQL on live data, or check which tables are ingested. Discovers tables first and only writes KQL for ones that exist. Chained by the /*-investigation skills to answer "were we exposed?". Read-only. Reads $SENTINEL_TENANT_ID, $SENTINEL_CLIENT_ID, $SENTINEL_CLIENT_SECRET and $SENTINEL_WORKSPACE_ID.

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