Control an open or active Microsoft Excel workbook through the ChatGPT add-in or connected session. Use when the user tags the Microsoft Excel app in Codex or follows up on an established live Excel task. Do not use for standalone spreadsheet files or Google Sheets.

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-live-control' ] || [ -L ~/.agents/skills/'excel-live-control' ]; then echo 'A skill folder named excel-live-control already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/asgeirtj/system_prompts_leaks' "$d" && git -C "$d" checkout --quiet '2209631d6d3da737c22159ed03c5127734b187f3' -- 'OpenAI/Codex/plugins/spreadsheets/skills/excel-live-control' && mkdir -p ~/.agents/skills && cp -R "$d"/'OpenAI/Codex/plugins/spreadsheets/skills/excel-live-control' ~/.agents/skills/'excel-live-control' && 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-live-control' ~/.claude/skills/'excel-live-control' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
