Fine to try. Some of what it can do is expected: a research skill usually looks things up on the internet.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'lit-sync' ] || [ -L ~/.agents/skills/'lit-sync' ]; then echo 'A skill folder named lit-sync already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/Aperivue/medsci-skills' "$d" && git -C "$d" checkout --quiet 'e0ea3b0be3bf529aa0b94ee5fd8450e78848932c' -- 'skills/lit-sync' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/lit-sync' ~/.agents/skills/'lit-sync' && 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/'lit-sync' ~/.claude/skills/'lit-sync' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
