pumpkin
Let an agent identify pumpkins and their cultivars, explain cultivation, nutrition and uses, relay food and agricultural information from reliable sources, and separate pumpkins from other squashes and gourds by usage rather than a strict botanical line.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent identify pumpkins and their cultivars, explain cultivation, nutrition and uses, relay food and agricultural information from reliable sources, and separate pumpkins from other squashes and gourds by usage rather than a strict botanical line.
The large round fruit of certain cultivars of squash, mainly Cucurbita pepo, Cucurbita maxima and Cucurbita moschata, with a hard rind, usually orange, and seeds in a central cavity; grown for food, seeds and oil, for decoration and carving at Halloween, and for giant specimen competitions, with names and cultivars varying by region.
What it is for: Food, seeds, oil, decoration and competition.
It can be identify cultivars and species; explain cultivation and storage; relay nutrition and culinary uses; distinguish pumpkins from other squashes.

How it is recognised
Round hard-rinded squash fruit, usually orange
