USE WHEN: a homeowner has a specific quoted price for a named construction or renovation work item in Japan and wants to know whether that price is reasonable. DO NOT USE WHEN: there is no price yet (call ask), the caller wants the known overcharge tactics rather than a verdict on their own quote (call scan_tactics), or the caller wants publishable text (call draft_broadcast). Returns a verdict and a free third-party check path. It does not draft or post.

      What this check looks for
    Description, as the server wrote it
    Check whether a construction or renovation quote in JAPAN is fairly priced, against the open JCCDB (526,128 records: line items and observations) and Bitcoin-anchored verification records. Single entry point: pass one sentence. USE WHEN: the user has a quote or a price for building/renovation work in Japan and wants to know if it is reasonable; or wants to check a HORIZON SHIELD receipt or a jidec: citation; or asks about overcharging tactics used by contractors; or is looking for a verified contractor. DO NOT USE WHEN: the work is outside Japan; the question is not about construction or renovation; the user has already signed or paid and needs consumer-protection help; or there is an active emergency (gas smell, collapse, water not stopping). In those cases this tool does not answer - it returns the appropriate outside destination instead, and says so. Every reply carries verify (a URL that checks the answer) and limits (what the answer does NOT prove). Routing is a deterministic keyword table, not an LLM, so the same input always routes the same way. Examples: "is 800,000 yen high for exterior wall painting?" / "is jidec:entry:9 genuine?" / "how do I refuse a door-to-door sales pitch?" 日本の建設・リフォーム見積もりが適正かを確認する単一入口。日本語の一文で渡してよい。適正診断・台帳(JIDEC)の記録検証・過剰請求の手口・検証済み加盟店の4方向へ決定的に振り分ける。日本国外/建設以外/契約後の紛争/緊急時は**答えずに適切な外部の窓口を返す。**返り値には必ず verify(検証URL)と limits(証明していないこと)が入る。

Verifiable first-party prices only. Drafts only, no auto-posting. USE WHEN: the caller wants all three steps (audit, tactics, broadcast draft) for one named work item in a single call and will act on the combined result. DO NOT USE WHEN: only one step is needed. Call intake_estimate for a verdict on a specific quote, scan_tactics for the documented overcharge tactics, or draft_broadcast for publishable text. If the request is still a free-form question with no work item, call ask first. This tool never posts anything.
