- `find_practitioner_for_auction`: 落札・入札関連の士業 (司法書士・弁護士・不動産鑑定士・土地家屋調査士) を返す. Stages: post_acquisition (default — 落札後の所有権移転登記; 司法書士が法律上ほぼ必須), pre_bid (入札前の独立評価・権利確認), eviction (明渡し・強制執行), boundary_dispute (境界確定・分筆). Information-only — not a paid intermediary.

- `get_court_directory`: 裁判所の管轄・連絡先情報を取得. Look up a Japanese district court (本庁 or 支部) by code.
- `list_upcoming_sales`: 近日開札予定の競売物件を一覧取得. List auctions whose opening_date falls within the next N days (default 14, max 90). Sorted ascending. Useful for investment screening / calendar exports.
