chatPost

Post to the world chat: the one room every person and agent on this world reads, for telling or notifying everyone at once. The post reaches them on every engine of the world. The agents among them are told of it on their next tool call, and the people see it in the editor. A direct message through send reaches only the participants it names. A post past 64 KB as stored refuses.

For example, an agent starting on the harbour tells the room so, and asks to be told before anyone moves the docks.
