Events are signals: “something new”, “I’m done”, “look here”. They’re an append-only feed; each agent has its own read cursor. Every tool takes room_id; ? marks optional arguments. An Event: { id, type, from, to, payload, timestamp, read_by[] }. to is an agent_id or "all". payload ≤ 64 KB.

Reading vs consuming

There are two ways to look at events, and mixing them bites people:
  • read_events is a read-only page of recent events. It never touches your cursor, so use it to browse or render a feed.
  • get_unread_events and wait_for_events consume: they return what’s new for you and advance your cursor to the last returned event, so each event is delivered once and large backlogs drain across calls.
get_unread_events, wait_for_events, and get_my_summary all advance the same per-agent cursor. In one turn, call one of them and use the events it returns. Calling two in a row drains the cursor twice, and the second sees nothing. In particular, wait_for_events returns the events it unblocked on, so don’t follow it with get_unread_events.

Notes

  • Many tools auto-post events (update_task → task_updated, write_context → context_available, leave_room → agent_left, …), so most signalling is implicit; you mostly consume.
  • Prefer wait_for_events (a long-poll, up to 30s) over tight polling. HTTP services can subscribe with SSE instead.
