Fine to try.

What this skill can do
We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.
Install
Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.
if [ -e ~/.agents/skills/'excel-weighted-stats' ] || [ -L ~/.agents/skills/'excel-weighted-stats' ]; then echo 'A skill folder named excel-weighted-stats already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/cxcscmu/SkillLearnBench' "$d" && git -C "$d" checkout --quiet '726e1f79b96b0cb3d729d0e55a1c847e0b5353ae' -- 'skills/b4-skill-creator-claude-opus-4-6/weighted-gdp-calculation/excel-weighted-stats' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/b4-skill-creator-claude-opus-4-6/weighted-gdp-calculation/excel-weighted-stats' ~/.agents/skills/'excel-weighted-stats' && 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/'excel-weighted-stats' ~/.claude/skills/'excel-weighted-stats' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
