  "description": "An independent, pre-transaction auditor for construction and renovation estimates. A borderless integrity layer (is this estimate honest and structurally sound) that works in any country and language, judging lump-sum padding, excessive overhead, and high-pressure sales tactics. Built on 30 years of field experience by a Japanese master carpenter. Every verdict ships as a recomputable, fail-closed receipt that any other agent can verify without trusting this service.",

      "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.",

IMPORTANT: this skill only receives and routes the consultation. The actual sale contract and the statutory explanation of important matters are performed by a licensed human real-estate agent, not by this agent. No binding price quote or property recommendation is asserted by the agent.",
