material
Let an agent explain materials and their properties, help select materials for applications, address safety and sustainability, and separate the information sense of material.
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 materials and their properties, help select materials for applications, address safety and sustainability, and separate the information sense of material.
A substance or mixture of substances that constitutes an object or is used to make things, such as metals, polymers, ceramics, composites, wood, textiles and construction materials, characterised by properties such as strength, conductivity and durability and studied in materials science; the word also denotes information or content relevant to a purpose, a separate sense.
What it is for: Making things and engineering.
It can be classify materials and explain properties; help select materials for a purpose; explain safety, recycling and sustainability; separate other senses of material.
