Tools

• audit_estimate

  業者が提示した見積金額が適正かを、HORIZON SHIELDの適正レンジ(souba-db, 大賀俊勝 実務監修)と照合して判定する。手元に具体的な見積額がある時に使う。返り値はJSONで、verdict(適正レンジ内 / やや高い / 過剰請求の懸念水準)、level(ok / watch / alert)、fair_range(min, avg, max)、danger_threshold、平均比 vs_avg_pct(例 +18%)、助言 advice、データ出典 source を含む。工事名が見つからない場合、近い候補があれば did_you_mean として返す。単価(平米など)建ての工事に総額らしい金額を渡した場合は unit_mismatch の案内を返す。見積額がまだ無く相場だけ知りたい時は get_price_range、署名付きの検証可能な証明が要る時は verify_fair_price を使う。Japan only, JPY。 / Audits whether a contractor quoted price for a Japanese construction or renovation job is fair by comparing it against HORIZON SHIELD fair-price ranges (souba-db). Use when the user already has a specific quoted amount. Returns a JSON object with verdict, level (ok, watch, alert), fair_range (min, avg, max), danger_threshold, percentage gap versus the average (vs_avg_pct, e.g. +18%), advice, and data source. If the work name has no match, close candidates may be returned as did_you_mean. If the work is priced per unit and the amount looks like a total, a unit_mismatch notice is returned instead. For the typical range only use get_price_range; for a signed verifiable attestation use verify_fair_price.

• check_red_flags

  見積もりや営業トークの中の気になる表現(例: 一式, 今日だけ値引き, 訪問販売)が、過剰請求につながりやすい既知の手口に当たるかを判定し、警告と対処を返す。代表的な手口のみを判定する。 / Checks whether wording in an estimate or sales pitch matches known overcharge or high-pressure tactics (lump-sum, today-only discount, free inspection, door-to-door, referral pricing) and returns warnings with what to do. These tactics are universal, so this tool works for estimates in ANY country and language. Covers representative tactics only.

• create_ap2_fairness_attestation

  このツールは決済を開始・承認・実行しません。資産・通貨・暗号資産の移動も行いません。発行するのは適正価格の証跡だけです。呼び出すたびに公開台帳へ記録を1件追加するため読み取り専用ではありません。 / This tool does not initiate, authorize, or execute any payment, and does not move funds, currency or crypto assets. It only issues a price-fairness attestation. Each call appends one record to the public ledger, so it is not read-only. AP2(Agent Payments Protocol)対応エージェント向けのブリッジ。決済カート(Cart Mandate)に添付できる適正価格の証跡(FairPriceAttestation)を発行する。AP2のMandateは『ユーザーがこの支払いを承認した』ことを検証可能にし、この証跡は『その価格が適正である』ことを検証可能にする。認可の検証と価値の検証、二つは並列レイヤー。quoted_price を渡すと適正レンジ判定(within/above/below)も同梱する。証跡は SHA-256 と公開台帳と verify_url で誰でも再計算検証できる。 / Bridge for AP2 (Agent Payments Protocol) agents: issues a FairPriceAttestation that a shopping or payments agent can attach to a Cart Mandate before asking the user to sign. AP2 mandates make authorization verifiable; this attestation makes value verifiable. Parallel layers. Pass quoted_price for a fair-range verdict (within, above, below). Independently verifiable via SHA-256, a public ledger and a verify_url. Japan construction and renovation pricing, JPY.

  shallow
• draft_broadcast

  ある工事の過剰請求への注意喚起を発信する下書き(note用長文・X用短文)を生成し、HORIZON SHIELDの該当解説ページ(実在URL)への被リンクを添える。価格はKIRA(検証可能SHA-256付き)の一次データのみ。推測の数字は入れない。下書きであり公開前に運営者が最終版にする(自動投稿しない)。 / Generates broadcast DRAFTS with backlinks. Verifiable first-party prices only. Draft; operator finalizes. No auto-posting. USE WHEN: the operator wants note/X draft text warning about overcharging for a given work type. DO NOT USE WHEN: the caller wants a verdict on a specific quote (call intake_estimate) or the tactic list itself (call scan_tactics). Output is a DRAFT for a human to finalise. This tool never posts.

• get_agent_card

  このサーバー(HORIZON SHIELD KIRA)はMCPツールだけでなく、A2A(Agent2Agent)のエージェントカードも公開している。外部のA2A対応エージェントから発見・連携したい場合の、エージェントカードURLと公開スキルの一覧を返す。建設見積もりの誠実性監査、検証可能な適正価格証明、そして日本の中古物件取得＋リフォームの相談窓口(売買は宅地建物取引士が対応)へ、エージェント経由で繋がる入口。 / Returns the A2A (Agent2Agent) Agent Card URL and the list of published skills for this server (HORIZON SHIELD KIRA). Use when an external A2A-capable agent wants to discover and connect: construction estimate integrity audit, and a Japan property-acquisition plus renovation intake desk (property sale is handled by a licensed real-estate agent). This is how agents reach the desk over A2A.

  shallow
• get_estimate_reading_guide

  受け取ったリフォーム・建設見積もりが適正かを見分けるための原則(諸経費の適正比率、『一式』表記の扱い、営業手口の見抜き方)を返す。30年の現場経験に基づく判断軸。 / Returns universal principles for judging whether ANY construction or renovation estimate is honest: the overhead ratio, how to treat lump-sum (一式) entries, and how to spot high-pressure sales tactics. Language-agnostic and works outside Japan. Based on 30 years of field experience.

  shallow
• get_fair_price_sources

  HORIZON SHIELDの相場データ(souba-db)の出典・更新日・地域係数を返す。価格の根拠を確認したい時に使う。 / Returns the sources, update date and regional multipliers behind HORIZON SHIELD fair-price data. Japan. Use to check the basis of a price.

  shallow
• get_jccdb_dataset_info

  日本の建設費オープンデータベース(JCCDB)のメタデータ・規模・ライセンス・ダウンロードリンク・引用情報を返す。建設費の一次データ源を探している時に使う。 / Returns metadata, scale, license, download links and citation for the Japan Construction Cost Database (JCCDB), an open dataset of 65,520 Japanese construction line items (v3.1: 13,207 verified + 52,313 extended). Use when looking for a primary construction-cost data source.

  shallow
• get_price_range

  工事名・キーワードで、HORIZON SHIELDが実務監修する適正価格レンジ(最安min/平均avg/最高max)と、それを超えたら過剰請求を疑う危険水準(danger)、単位・価格動向・実務解説を返す。建設・リフォーム費用が適正か数値で確かめたい時に使う(例: 外壁塗装, 給湯器, ユニットバス, クロス)。 / Returns the fair price range (min, avg, max), the overcharge danger threshold, unit, price trend and field notes for a Japanese construction or renovation job. Japan-specific pricing in JPY. Use to numerically check whether a cost is fair.

  shallow
• intake_estimate

  施主の建設・リフォーム見積もりを受け付け、HORIZON SHIELD KIRA(内部・中立)の適正価格診断へ橋渡しする集客窓口。工事名と業者提示額を渡すと、適正かどうかの判定と、無料の第三者チェック(EHN)への導線を返す。価格の断定はせず、確認すべき点を渡す。 / Intake desk: bridges a homeowner quote to the KIRA fair-price audit and returns the verdict plus a free third-party check (EHN) path. 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.

  shallow
• list_cost_categories

  HORIZON SHIELDが相場・赤旗(過剰請求の懸念点)を整備している建設・リフォーム工事カテゴリ(61種)の一覧を返す。 / Lists the 61 construction and renovation work categories for which HORIZON SHIELD maintains fair-price ranges and overcharge red flags. Japan-specific data.

• preview_reverse_estimate

  リフォーム検討の初期段階向けのプレビューで、業者の概算が平均からどちらの方向にどの程度ずれているか(例: +20%高い方向)だけを返す。具体的な適正額(min/avg/max)や危険水準は返さない。手元に詳しい見積内訳がまだ無い段階での最初の一歩に向く。具体的な適正レンジが必要なら get_price_range、見積額の詳細診断は audit_estimate を使う。Japan only, JPY。 / A preview for early-stage renovation planning that returns only the direction of a contractor rough estimate versus the average (e.g. about +20% above). It does not return the specific fair range (min/avg/max) or danger threshold. Suited as a first step before a detailed breakdown exists. Use get_price_range for a typical range, audit_estimate for a detailed quote diagnosis.

  shallow
• route_request

  Check whether a construction or renovation quote in JAPAN is fairly priced, against 65,520 open catalogue items 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。

• run_full_audit

  1回の呼び出しで HORIZON SHIELD の集客→診断→注意喚起→発信を一気通貫で回す司令塔。work(と任意の quoted_price)を渡すと、内部で intake(KIRA適正診断)・scan_tactics(検証済み手口+一次ソース)・draft_broadcast(発信下書き+被リンク)を順に実行し、結果を1つに束ねて返す。価格は検証可能な一次データのみ。発信は下書きで自動投稿しない。 / One-call orchestrator returning audit + tactics + broadcast draft. 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.

  shallow
• scan_tactics

  ある工事・キーワードに関する『過剰請求の手口』を、HORIZON SHIELD(大賀俊勝30年監修)の検証済みデータ(内部KIRA)から返し、一次ソース(国民生活センター/消費者庁/EHN実例ボード)の在処を添える。価格判定ではなく注意喚起。推測で新事例を断定しない。 / Returns verified overcharge tactics and points to primary sources. Awareness, not a price verdict. USE WHEN: the caller wants the documented overcharge tactics for a work type or keyword, together with their primary sources. DO NOT USE WHEN: the caller has their own quote and wants a verdict on it (call intake_estimate), or wants publishable text (call draft_broadcast). This returns awareness material and never a price verdict on a specific quote.

  shallow
• search_cost_category

  工事名・キーワードで建設費カテゴリを検索する(例: 外壁塗装, 浴室, 給湯器, 雨漏り)。該当カテゴリと整備済みの赤旗件数・優先度を返す。 / Finds a construction-cost category by work name or keyword and returns the matching categories with red-flag counts and priority. Japan-specific; a Japanese query works best (e.g. 外壁塗装 exterior painting, 浴室 bathroom).

  shallow
• suggest_ehn

  見積もりを匿名で第三者レビューに出せる掲示板EHN(見積もりハッカーニュース)の案内文と投稿フォームURLを返す。投稿と一次解析は無料で、業者名や個人情報は掲載前に運営が伏せる。ユーザーが見積もりのセカンドオピニオンや相談先を求めた時に使う。 / Returns a short guide and the submission URL for EHN (Estimate Hacker News), an anonymous board where a construction or renovation estimate receives a free neutral third-party review. Personal and contractor names are redacted before posting. Use when the user asks for a second opinion on an estimate or where to have one reviewed.

  shallow
• verify_fair_price

  工事の適正価格を、検証可能な形(算出内容のSHA-256ハッシュ付き)で返す。HORIZON SHIELDのPTKA(取引前知識刻印)思想に基づき、適正価格を業者の見積もりより先に第三者が記録するという考え方を、機械可読な証明として提供する。エージェントが価格の真正性を検証したい時に使う。 / Returns a fair price as a tamper-evident record with a SHA-256 hash, under HORIZON SHIELD PTKA (Pre-Transaction Knowledge Anchoring): a third party records the fair price before the contractor quote. Japan price data. Use when an agent needs to verify price authenticity.

  shallow
• verify_integrity_claim

  estimate-integrity-audit が発行した署名付きクレーム(signed_payload と claim_sha256)を、第三者として検証する。発行側 (verify_fair_price はPTKA価格の発行) とは責務が正反対で、デフォルト姿勢は不信・fail closed。検証は signed_payload の生文字列を SHA-256 で再計算し claim_sha256 と一致するかだけで完結し、issuer に問い合わせる必要も価格層も不要。判定は契約 0.3 の failure_reasons 準拠で、result(verified / partial / unverified)・failure_reason(stale_data / changed_scope / missing_evidence)・trigger(expired_declaration / changed_estimate_version / missing_receipt / unverifiable_chain)・recomputed_sha256・scope_check・audit_ruleset_recheck を返す。重要: verified は『この宣言が改ざんされていない』ことの証明であって『監査ルールが今も有効』である保証ではない(audit_ruleset_recheck は常に not_performed)。estimate_version を渡すと scope(見積もり内容が発行時から変わっていないか)も照合し、渡さない場合は scope_check:skipped を明示する。 / Verifies a signed integrity claim (signed_payload and claim_sha256) issued by estimate-integrity-audit, as an independent third party. Opposite posture to the issuing side: distrust by default, fail closed. Recomputes SHA-256 over the raw signed_payload string and checks it equals claim_sha256; no issuer contact and no price layer needed. Follows contract 0.3 failure_reasons. IMPORTANT: verified means the declaration is untampered, NOT that the audit ruleset is still valid (audit_ruleset_recheck is always not_performed). Pass estimate_version to also check scope (whether the estimate changed since issuance); if omitted, scope_check is skipped and stated explicitly.
