What the code does

We read the source, 1 d ago · tools taken from the live server · rules 995398eba69f

Evidence

Things with no honest explanation: a promise that contradicts the code, code that runs at install time while hiding what it does, data leaving the machine.

Claims read-only, but the code runs commands data/jccdb-obs-v2/tools/parsers/check_mlit_gijutsusha_series.py:52, data/jccdb-obs-v2/tools/parsers/check_mlit_roumu_series.py:61, data/jccdb-obs-v2/tools/parsers/mlit_grid.py:22 и ещё 52

    t8 = N(subprocess.run(["pdftotext", "-layout", os.path.join(OBS2, "raw", "mlit-gijutsusha-r8.pdf"), "-"], capture_output=True).stdout.decode())

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Builds a file path from a variable paint-monitor/feed_emitter.py:45, data/jccdb-obs-v2/tools/migrate_v1.py:16, data/jccdb-obs-v2/tools/parsers/dbra_stage_to_raw.py:31 и ещё 42

We found things in this code

Code changes quietly between releases, and nobody reads the diff of a dependency. We do, on every release — watch HORIZON SHIELD: Construction Estimate Auditor for Japan (KIRA) and you get told the day something new turns up.

Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

draft

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.

full

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.

intake

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.

route

route_request

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。

scan

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.
