Fine to try.

By polar-bear-org/claude-skills (GitHub) · design · 54 stars · scanned at commit 95f0180

Builds a TAM, SAM and SOM estimate from top-down and bottom-up sizing as low, base and high, with every input sourced or labelled assumption, the gap between the two methods shown and the share of the reachable market the plan needs. Use for "run strat-market-sizing", "market sizing", "TAM SAM SOM", "how big is this market", "bottom-up market size", "is this market big enough", "where does that number come from", part of the Claude Guide for Product Strategy Pack by 90n.

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