What problem does it solve? Product teams often have a list of strengths but no clear picture of who actually needs them badly enough to buy. This Skill turns a strengths chart into a keystone chart — the specific customer circumstances that require an extreme version of each strength — revealing which market segments the product is genuinely compelling to. ## Core Features & Use Cases - Strength-by-strength walkthrough: Walks each classified strength (S1, S2, …) one at a time, generating keystone candidates with the user and testing each against a requires-not-prefers bar. - Segment gate enforcement: Cuts any candidate that cannot name a real, significant market segment that typifies it, recording rejected strengths as table stakes with reasoning. - Structured KEYSTONES.md output: Records surviving keystones (K1, K2, …) with [S-number] references, example segments, a table-stakes section, and an honest verdict when one or zero keystones survive. - Use Case: After classifying your product's strengths and weaknesses, run this Skill to discover that "fast website" only becomes a keystone for e-commerce stores where speed measurably moves revenue — sharpening your target market definition. ## Quick Start Read my STRENGTHS-WEAKNESSES.md file and walk me through turning each strength into keystones with real market segments.
