Use for "run deck-numbers-check", "check the numbers in this deck", "trace every figure", "do these numbers match", "is anything made up", "numbers before the board", "which chart for this figure", part of the Claude Slides for Product Manager…

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/'deck-numbers-check' ] || [ -L ~/.agents/skills/'deck-numbers-check' ]; then echo 'A skill folder named deck-numbers-check already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/polar-bear-org/claude-skills' "$d" && git -C "$d" checkout --quiet '95f01806ca43f6ee788d0579743e35853b695930' -- 'packs/slides-for-product-managers-pack/skills/deck-numbers-check' && mkdir -p ~/.agents/skills && cp -R "$d"/'packs/slides-for-product-managers-pack/skills/deck-numbers-check' ~/.agents/skills/'deck-numbers-check' && 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/'deck-numbers-check' ~/.claude/skills/'deck-numbers-check' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
