What problem does it solve? Product teams often know their product's weaknesses but never translate them into clear market boundaries, so marketing and sales keep chasing segments that will never buy. This Skill walks each classified weakness, identifies the circumstances where it disqualifies the product outright, names the anti-market segments behind them, and sharpens existing keystone customer segments with the qualifiers those deal-breakers force. ## Core Features & Use Cases - Deal-breaker mapping: Walks weaknesses (W1, W2, ...) one at a time, gating each candidate on whether it truly disqualifies rather than merely annoys, and records results in DEALBREAKERS.md with stable D-numbers. - Keystone honing: Edits KEYSTONES.md segment lines under frozen K-numbers, appending concrete qualifiers (e.g., "processing at least $5,000/mo") with a dated change log. - Friction vs. deal-breaker distinction: Records weaknesses that cost points but disqualify no one as backlog input instead of market boundaries. - Use Case: After completing a strengths/weaknesses chart and a keystones file for a hosting product, run this step to discover that "expensive" disqualifies sub-$5k/mo stores, then hone the e-commerce keystone segment accordingly. ## Quick Start Run the deal-breakers step on my STRENGTHS-WEAKNESSES.md and KEYSTONES.md files to map who will never buy and hone my keystone segments.
