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 menarche in general terms, relay health information and guidance from paediatric and public health sources, describe cultural practices with attribution, and route personal or clinical questions to clinicians and appropriate support.

The first menstrual period, marking a milestone of puberty in girls and typically occurring between about 10 and 16 years of age, with an average near 12 to 13 in many populations; its timing is influenced by genetics, nutrition and health, and it is treated in many cultures with rites and in health systems with education and care.

It can be explain what menarche is and its typical timing; relay health education and guidance; describe cultural practices with attribution; route personal questions to clinicians.
