Indo-European
Let an agent explain the Indo-European language family, its branches, reconstruction methods and origins debates, and support comparing and learning its languages with attributed scholarship.
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 the Indo-European language family, its branches, reconstruction methods and origins debates, and support comparing and learning its languages with attributed scholarship.
A large family of related languages descended from a reconstructed common ancestor, Proto-Indo-European, including the Germanic, Romance, Slavic, Celtic, Baltic, Hellenic, Armenian, Albanian, Indo-Iranian and extinct Anatolian and Tocharian branches, spoken as first languages by nearly half the world population.
What it is for: Historical linguistics and understanding language relationships.
It can be explain the branches and their languages; explain the comparative method and reconstruction; summarise origin hypotheses with attribution; trace cognates across languages.
