What problem does it solve? Product teams often commit build capacity to bets based on enthusiasm rather than a defensible case. This Skill forces every opportunity through Marty Cagan's 10-question assessment, where each answer must rest on one statable assumption a skeptic can attack, turning go/no-go decisions into checkable claims instead of hand-waving. ## Core Features & Use Cases - Structured 10-Question Gate: Walks problem, target market, market size, competition, differentiation, timing, go-to-market, metrics, success factors, and recommendation as ten checkable claims. - Single-Challengeable-Assumption Discipline: Requires each answer to compress into one sentence a skeptic could disagree with, exposing the weakest link to test first. - Copy-Paste Artifact: Produces a ready-to-use assessment table with a weakest-link callout and a reasoned pursue/defer/reject recommendation. - Use Case: Before committing a quarter to a CSV export feature, run the assessment to discover the market size is undefended, route that question to market-sizing, and defer the bet with documented reasoning. ## Quick Start Ask the AI to run an opportunity assessment on your proposed initiative and produce the ten-question table with the weakest-link assumption identified.
