Start with a market question. This skill builds a bounded TrustMRR cohort, checks pagination and money units, separates payment-provider-backed observations from marketplace and founder claims, and turns the evidence into a decision memo with a 1-7 day validation test.
It includes a deterministic Python validator for revenue pools, quartiles, medians, concentration, duplicate detection, page-clamp detection, and detail-coverage checks. If the data cannot support a monetary conclusion, the workflow says so instead of guessing.
TrustMRR access is separate. You need your own developer API key and an MCP client that can bind bearer authentication through a secret store or environment variable.
