Fine to try.

Create, inspect, and edit Microsoft Excel workbooks and XLSX files with reliable formulas, dates, types, formatting, recalculation, and template preservation. Use when (1) the task is about Excel, `.xlsx`, `.xlsm`, `.xls`, `.csv`, or `.tsv`; (2) formulas, formatting, workbook structure, or compatibility matter; (3) the file must stay reliable after edits.

Works with any agent that supports SKILL.md skills.

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-xlsx' ] || [ -L ~/.agents/skills/'excel-xlsx' ]; then echo 'A skill folder named excel-xlsx already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/HKU-MMLab/UniClawBench' "$d" && git -C "$d" checkout --quiet 'a8ac4df6c554178c339f42696e3afe688a61f4b7' -- 'injection/101_skill_usage/task_101_02_sales_csv_xlsx/skills/excel-xlsx' && mkdir -p ~/.agents/skills && cp -R "$d"/'injection/101_skill_usage/task_101_02_sales_csv_xlsx/skills/excel-xlsx' ~/.agents/skills/'excel-xlsx' && 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-xlsx' ~/.claude/skills/'excel-xlsx' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
