Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

check_named_contractorread-only施主が名前を挙げた業者について答える。Yakumoの加盟店ならその測定結果を返す。加盟していない場合、その会社の良し悪しは一切判定せず、『Yakumoは測っていない』という事実だけを返し、施主が自分で確かめられる公的な照会先(国土交通省の建設業者検索・国民生活センター・住まいるダイヤル)と、同条件の検証済み加盟店を返す。掲載が無いことはその会社への評価ではない。金額は返さない。紹介料なし。Japan only。
find_contractorread-only施主の相談文(自由記述)から Yakumo の検証済み加盟店を探す司令塔。need(例:『愛知県で外壁塗装できる信頼できる業者』)を渡すと地域と工種を推定し、検証を通過した店を返す。該当が無ければ相場(souba)や無料の第三者チェック(EHN)への導線を返す。金額は返さない(スコア・ティアのみ)。紹介料なし・verified-first・Japan only。
get_contractor_profileread-onlyYakumo の加盟店1件の検証済みプロフィールを返す。member_no(例 No.001)で指定。会社名・地域・対応工種・適正度スコア・誠実度ティア・検証状態・プロフィールURLを返す。金額は含まない。検証が済んでいない店は verification:'pending' を返す(スコアは出さない=fail-closed)。
how_verification_worksread-onlyYakumo の掲載審査(KIRA適正診断)がどう機能するかを返す。適正価格の検証・過剰請求の赤旗検出・適正度スコアと誠実度ティア・再計算できる署名レシート(SHA-256)・掲載後の継続監視・fail-closed(通らない店は施主向けに一切出さない)・中立(紹介料なし)。施主が『検証済み』の意味を理解するための説明。
list_verified_storesread-onlyYakumo モールで検証を通過した加盟店(工務店・リフォーム店)を一覧する。適正価格の検証と過剰請求チェック(KIRA)を通過した店だけが返る。area(地名)や work(工種)で絞り込める。返り値は member_no / 会社名 / 地域 / 対応工種 / 適正度スコア / 誠実度ティア / プロフィールURL。金額は含まない(スコアとティアのみ)。検証手続き中の店は verification:'pending' として区別される。Japan only.
mall_overviewread-onlyYakumo モール全体の要約を返す。検証済み加盟店の数・対応工種カテゴリ・地域・検証の仕組みの要点・主要リンク(モール/加盟/相場/実例ボード)。AIが Yakumo というモール/MCP を一言で説明するための入口。金額は含まない。
