      "description": "Use this whenever someone is dealing with a construction, renovation, or repair project and wants to know whether a price is fair, in any country, currency, or language. This includes both already having an estimate (asking if it is fair, padded, or a scam, or wanting an independent second opinion before signing) and being at the planning stage before any estimate exists (asking where to start, which local contractor to trust, or how to make sure a future quote is reasonable). Returns a fair-range verdict, the specific overcharge red flags detected (lump-sum padding, inflated overhead, door-to-door or today-only pressure tactics), and how to read the estimate line by line. Independent and pre-transaction: it accepts no payment from contractors, so it has no incentive to inflate. Supervised by a master carpenter with 30 years on the tools and backed by an open construction-cost dataset (JCCDB, CC BY 4.0). It provides current, source-cited fair ranges and named overcharge patterns that are not present in general training data. Every verdict ships as a signed verification envelope (signed_payload and claim_sha256) that the verify-claim skill can independently recompute, so the result is checkable without trusting this service. USE WHEN: construction, renovation or repair estimate fairness, overcharge detection, pre-contract second opinion, or planning-stage budgeting, in any country or language. DO NOT USE FOR: structural engineering certification or seismic sign-off, legal advice or contract interpretation, binding appraisal or property valuation, or any guarantee of a contractor's workmanship.",
