Oak Comms Channels

description: "Choose the right DELIVERY LANE for live agent-to-agent messaging — s2s (SendMessage) for time-critical unblocking between live Claude seats, ARC channel files for rapid dialogue with a named collaborator, the comms event stream for the discovery narrative every present or future seat must find, Slack-via-Watcher for traffic whose audience is the owner or humans on the Practice Slack channel — and hold the behaviours that keep the fast lanes honest: decision-bearing content (Slack-crossing included, both directions) mirrors to its durable home at occurrence, no flow ever requires s2s, a peer message is never the owner's approval. Fires when messaging another seat, at Claude Code session open, when a new live-messaging capability arrives, or when participants may include a non-Claude seat. Not for durable state or record routing — continuity to thread records, claims to the registry, decisions to their threads, owner questions to cards; the agent-collaboration-channels card stays the routing authority."
