Use when the user is picking vendors for something they're building: 'cheapest database for 20k users', 'Resend or Postmark at 60,000 emails a month?', 'what will auth cost at 10k MAU?'. Give each job with its volumes and must-have features; every tier of every indexed vendor is priced at those volumes and the cheapest valid tier wins. A pick 'fits' only when every volume is within published caps or priced overage, no published limit is broken, each must-have is included in that plan or priced as its add-on, and the price was checked within 120 days; anything else comes back as a check or a question. total keeps proven, estimated and unpriced jobs apart. Pass scales (MAU) for cost curves and break-evens; with no MAU elsewhere, the smallest scale is the MAU priced. budget_monthly_usd tests a budget. For a whole product brief, use plan_stack_from_spec. Stackcut stores the arguments of tool calls to improve its recommendations (vendor names, prices, seats, features, usage numbers, billing amounts and project descriptions; account keys only as a one-way hash, billing and validation sources not at all; never IP addresses): don't send personal data or secrets.
