Purpose Guide product managers through calculating Total Addressable Market (TAM), Serviceable Available Market (SAM), and Serviceable Obtainable Market (SOM) for a product idea by asking adaptive, contextually relevant questions. Use this to build defensible market size estimates backed by real-world citations, economic projections, and population data—essential for pitching to investors, securing budget, or validating product-market fit. This is not a back-of-napkin guess—it's a structured, citation-backed analysis that withstands scrutiny. Input Works best with: The product or idea being sized, and any market constraints you already know (geography, vertical, customer type). Also useful: Pricing assumptions, comparable companies, and the audience for the numbers (investors, execs, business case). Anything supplied with the invocation itself — text after the skill name, a pasted context dump, or an appended ARGUMENTS: line — counts as answers already given.
