Singapore Land Lots & Master Plan Zoning

The four tools map to distinct intents: search for lots, get a lot's details, get a map image, and get Master Plan zoning at a point/zone id. The only real overlap is that SG_land_use_get accepts a coordinate while SG_lot_get also returns zoning (zona) for a lot, which could occasionally make an agent hesitate between them, but the descriptions clearly separate point-level zoning from lot-level lookup.

All tools share the SG_<resource>_<action> pattern (SG_lot_search, SG_lot_get, SG_lot_image, SG_land_use_get), which is predictable and readable. The minor deviation is that 'image' is a noun rather than a verb like get/search, and land_use nests a multi-word resource, but neither harms comprehension.

Four tools is lean but each covers a genuinely different need (discovery, detail, visualization, zoning), so nothing feels redundant. It sits at the low end of the comfortable range, but for a narrow geospatial lookup domain that is reasonable rather than deficient.

The surface covers the core lifecycle: find lots by key/number/coordinates, inspect a lot with zoning and optional geometry, visualize surrounding lots, and query zoning at any point in Singapore. Gaps are minor and largely delegated (address/postal-code geocoding must be done externally, and there is no search by land-use class or bulk enumeration), which agents can work around.
