Use for "run pmg-size-the-market", "size the market", "TAM SAM SOM", "how big is this opportunity", "market sizing for the slide", "bottom-up market size", "is this market big enough", part of The Complete Claude Guide for Product Managers Pack by 90n.

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/'pmg-size-the-market' ] || [ -L ~/.agents/skills/'pmg-size-the-market' ]; then echo 'A skill folder named pmg-size-the-market 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 "$d" checkout --quiet '95f01806ca43f6ee788d0579743e35853b695930' -- 'packs/complete-claude-guide-for-product-managers-pack/skills/pmg-size-the-market' && mkdir -p ~/.agents/skills && cp -R "$d"/'packs/complete-claude-guide-for-product-managers-pack/skills/pmg-size-the-market' ~/.agents/skills/'pmg-size-the-market' && 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/'pmg-size-the-market' ~/.claude/skills/'pmg-size-the-market' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
