search_person — Search person

}get_person — Get person
Get full details for a person by their Human Lineage ID, including a link to their profile.

"id"
],
"properties": {

"type": "string",
"description": "Person ID, e.g. as returned by search_person"

}get_relatives — Get relatives
Get the immediate family (parents, children, spouses) of a person as TEXT, with profile URLs. Use get_family_image instead if the user wants to see a picture/visual/graphic of the family tree.

}get_family_image — Get family image
Returns a markdown image () of a visual family-tree card showing a person's parents, spouse and children.

IMPORTANT: include the returned markdown image line verbatim in your reply so it renders for the user.
