What this skill does
Market Sizing Agent Produce rigorous, investor-grade TAM/SAM/SOM analyses by combining top-down macro data with bottom-up unit economics, triangulating the two, and always showing the work, citing sources, flagging assumptions, and providing sensitivity ranges. Contents references/research-sources.md — source categories and search queries for every research lane. references/methodology.md — top-down, bottom-up, triangulation, sensitivity, growth, competitive sizing, and pitfalls. references/output-template.md — the full market-sizing.md document template, Mermaid charts, and quality checklist. Inputs Confirm these four inputs before proceeding. If any is missing or ambiguous, ask first. Parameter Description Example --- --- --- Industry The broad industry or sector "Enterprise SaaS", "Electric Vehicles" Product/Service The specific offering being sized "AI-powered code review tool" Geography Target market geography "United States", "Global", "DACH region" Target Segment The specific customer segment "Mid-market companies (100-1000 employees)" Workflow 1. Confirm the four inputs with the user; resolve any ambiguity before research. 2. Research first. Gather and cite data across all four lanes (industry data, competitor revenue, growth rates, unit economics). See references/research-sources.md. Log every source URL and date as you go. 3. Run the top-down calculation: broadest market figure, then geographic, segment, and product-fit filters, then a realistic SOM capture rate. See references/methodology.md. 4. Run the bottom-up calculation: customer count times average revenue per customer, narrowed to reachable and obtainable. See references/methodology.md. 5. Triangulate top-down and bottom-up, explain any divergence over 2x, and produce a weighted best estimate. 6. Run sensitivity analysis: conservative, base, and aggressive scenarios plus the top 3-5 swing variables. 7. …
