+files as the root. The root's ``agent_create(name, responsibility)``
+tool creates and starts it with the root's model, effort, and working
+directory, and a separate random ID. A name describes the area, such as
+``House`` or ``Calendar``. It is one word of 2 to 32 ASCII letters,
+starts with a capital letter, and cannot name the root, an existing
+child, or a subagent. The daemon opens all children at startup. A
+missing or invalid child config stops startup. Only one level of
+children is supported. Remove a child by hand while the daemon is
+stopped. The root's turn state lists each child and its responsibility.
+The root passes area messages from mixed chats with sender, date, and
+words, and asks the user before it sends a child's draft to WhatsApp.
