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.
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.
