### Tool changes

- 2026-11-14 `find_yards` changed (description)
  - before: Start here (step 1 of 3). Find Seacoast ME–NH and Casco Bay boatyards, marinas, moorings and storage near a town (public-web listings, not partners). Example: {"region":"seacoast","q":"kittery"}; then pass a returned id to get_yard and price the job with get_seacoast_costs. All arguments are optional; no arguments lists every yard. Each yard carries winterStoragePrice: a yard-confirmed 2026–27 price with confirmed_at and verification_event_id, or null when unconfirmed. Set confirmed=true for confirmed yards only. Human-readable index: /yards. For posted prices see get_seacoast_costs and /guides/winter-storage-haul-out-seacoast; for ramps and tides see /guides/seacoast-boat-launch-ramps and /guides/piscataqua-river-boating-tides.

- 2026-11-11 `get_seacoast_costs` changed (description)
  - before: Seacoast ME–NH winter-job prices: posted storage, winterize, haul and spring commissioning rates from yards' own rate pages (each with source_url and the date read), plus yard-confirmed winter storage prices. Advisory, not quotes. Pass loa_ft to filter by boat length and get per-foot arithmetic. Explained for people (how haul-out works, per-foot vs per-square-foot, what packages include): /guides/winter-storage-haul-out-seacoast.
  - after: Step 3 of 3 (also fine as a first call). Seacoast ME–NH winter-job prices: posted storage, winterize, haul and spring commissioning rates from yards' own rate pages (each with source_url and the date read), plus yard-confirmed winter storage prices. Advisory, not quotes. Example: {"service":"storage","state":"ME","loa_ft":26}.
