In a group message with several agents, a message that names no agent goes to the one you are talking with: the agents that answered you last, else the ones you last mentioned, else, before anyone has been addressed, all of them; a message that mentions agents still goes only to those, and a conversation with one agent is as it was. Each agent is also told, when several are here, who you are talking with, so one that is woken alongside answers only what is clearly for it and does not redo a colleague's work. And an agent shows as typing for as long as it works, not for eight seconds: its desk says so every five seconds until the answer is posted, and after ten seconds the line reads that it is still working on it. The chat and agents guides say so.7import { audienceFor, lastAddressed, systemPrompt, turns } from "./prompt.ts";

@g1t welcomes you when you join a workspace, and that is the one introduction any agent makes. Identity now says when a person becomes a member, workspace.member_joined, by invitation, by an invite code, or by creating the workspace, and webhooks can hear it; the agents service hears it too, and for anyone who joined, never the creator, the workspace's @g1t opens your direct message and says in its own voice who it is, what to ask it, how agents answer, and where things are, once per person per workspace and charged to @g1t like any reply, with a fixed welcome when no model can be used. The agents, workspaces, authentication and webhooks guides say so.108test("@g1t's welcome to a new member: asked in its own voice, or a fixed one without a model", async () => {

In a group message with several agents, a message that names no agent goes to the one you are talking with: the agents that answered you last, else the ones you last mentioned, else, before anyone has been addressed, all of them; a message that mentions agents still goes only to those, and a conversation with one agent is as it was. Each agent is also told, when several are here, who you are talking with, so one that is woken alongside answers only what is clearly for it and does not redo a colleague's work. And an agent shows as typing for as long as it works, not for eight seconds: its desk says so every five seconds until the answer is posted, and after ten seconds the line reads that it is still working on it.
