- 2026-10-08 `find_land` changed (description, outputSchema)
  - before: Use when someone wants to find land or lots in Austin or Nashville that fit a need, for example lots where three homes are allowed, commercial land where apartments are allowed without a rezoning, dry industrial land of 5+ acres, zoning where whole-home short-term rentals are permitted, or Specific Plans whose ordinance bans rentals. Pick a ready-made view or describe the need in plain English. Returns how many zoning areas and acres match, the largest ones with a point to pass to land_at, and a map link. Austin views: home3, sb840, co, interim, mfdry, ind5, hist, bsz. Nashville views: strok, spstr, ns, unbuilt, mfusd, ind5, hist, dadu.

- 2026-10-08 `land_at` changed (description, outputSchema)
  - before: Use when someone asks what they can do with a specific property or address in Austin, TX or Nashville, TN: what it is zoned and what that means, how many homes the lot can take (Austin HOME rules, Texas SB 840 apartments on commercial land), what the zoning ordinance or Nashville Specific Plan says, whether a short-term rental (Airbnb) is allowed, the property tax and flood risk. Give an address or a latitude and longitude. Returns the answer, the sources, a map link and a printable brief link. For a Nashville or Austin lot, when the paid Lot File is on sale in that city and covers the lot, it also returns lot_file: what the cited file adds (documents read, rules computed for the lot, pending cases) and the link to buy it.
