Product Idea Stress Test

Use this when Product Idea Stress Test has already selected this skill because external evidence would materially improve a named claim, hypothesis, competitor or substitute analysis, prior-attempt search, pricing analysis, or disconfirmation. Do not use merely because a product idea was provided. Do not use for the opening line, empty chat, unresolved founder branches, Method or Preference material, or to issue the overall verdict.

Use this when Product Idea Stress Test has already named a Bottleneck Belief or equivalent primary uncertainty and has selected this skill because an experiment would help. The uncertainty is an input from methodology. Do not invent or replace it. Do not use for empty chat, unresolved clarifying questions, or to issue capital allocation or the overall verdict.

Use this when Product Idea Stress Test has classified substantial user-provided material as Method (a framework, rubric, investment memo, operating principle, or way of evaluating ideas) and needs an optional reasoning lens. Do not use for Evidence, Preference, or Context alone. Do not edit methodology.md. Do not use for empty chat or to issue the overall verdict.
