Let an agent explain kerbs and their functions and types, describe design and accessibility standards, interpret kerb markings and parking rules, and support road maintenance questions.
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 explain kerbs and their functions and types, describe design and accessibility standards, interpret kerb markings and parking rules, and support road maintenance questions.
The raised edge of a pavement or sidewalk where it meets a road, made of stone, concrete or other materials, separating pedestrians from traffic, guiding drainage and defining road edges, with forms such as dropped kerbs for accessibility, bus-boarding kerbs such as the Kassel kerb, and painted kerbs marking parking rules; kerbs are specified in road design standards and maintained by highway authorities.
What it is for: Edges between pavements and roads.
It can be explain functions and types; describe design standards; interpret markings; support maintenance questions.
