---

Open-source Claude Code skill (MIT) that turns dense market material — industry reports, transcripts, research — into a cold-email-ready offer: it identifies the real problem and its cost, then produces an Offer Sheet with market analysis, value proposition, elevator pitch and a targeting matrix for list building. Deliberately stops before copywriting.

## Provenance

- MIT independently WebFetch-verified 2026-09-12 (3★, 5 commits; skill files). Surfaced via the 2026-09-12 viral-posts brief (author's own launch post, strong bookmark rate at tiny follower count).
- Curated from the GTM Stacker signal registry (2026-09-12 pass: daily pull + viral-posts brief); license independently WebFetch-verified 2026-09-12.

## Why it matters for a GTM stack

Skills are becoming the distribution format for GTM method, not just code (this registry has cataloged the pattern since cold-outbound-skills in September). This one attacks the correct first bottleneck of outbound — the offer, not the email — and its two-phase method (understand the market, then anchor the offer to the gap) is worth reading even if you never run it.
