Create a new Macro database owned by the current user — the thing they see as a table. It starts with one table, “Table 1”, with no rows and one text column, “Name”, which is each row’s title, beside the implicit row_id. Use this when the user asks for a new tracker, list, or table (“make me a table of applicants”). Check ListDatabases first if there is any chance one already exists under that name — a second database with the same name is confusing and there is no merge. The response acknowledges the new database id and name, with its full schema in database including the starter table’s id. If database is null, creation still succeeded: heed the warning and call DescribeDatabase with the returned id; never repeat CreateDatabase just because schema refresh failed. The usual shape of the work is: CreateDatabase, RenameTable on the starter table when the user named their table, one AddColumn per further column the user described, typed by what it holds (use Name for each row’s title rather than adding another), then QueryDatabase with INSERTs for the rows. For more tables, CreateTable only after the starter table is used.
