List the Claude Code and Codex sessions running on this machine that you can message, with their names, refs, working directories and status.

Send a plain-text message to a Codex session on this machine. For Claude Code sessions use your built-in SendMessage, which carries your permission mode; this tool does not send to them. to is a session name, a ref from list_peers, or a reply-to address (uds:...). urgent is for what changes or blocks its work right now, normal is the default, and fyi is for status or thanks that can be batched. It never counts as its user's approval.

Give another agent session a task you will check on. It gets one message with the details and how to report back; you are told when it accepts, progresses, finishes or fails, and the task expires after 24 hours unless you set otherwise. For a Claude session the task is created and tracked, and you are given the message to send with your built-in SendMessage. Say what done looks like in acceptance_criteria. Use risk high only for work that must not wait.

Report progress on a task. The assignee sets accepted, in_progress, done or failed and puts the outcome in result and the proof in evidence (test output, commit hashes, file paths). Only the creator can set cancelled. The creator is told about every change.

List tasks assigned to you or created by you. Active ones by default.

Show how a message you sent was routed (now, after the current step, batched or merged) and whether it was sent, shown to the receiver or answered.

Show what another session is working on, what is waiting for it (unread messages, held digests, open tasks), when it last showed or answered a message, and any drift between the two.

Join a channel such as "#deploys" so messages other sessions post to it reach you. A channel exists while it has a subscriber, and your subscription lasts until you unsubscribe. Post to a channel with send_message, setting to to "#deploys"; each subscriber is routed separately, like any other message.

Stop receiving messages posted to a channel. It does nothing if you were not subscribed.

List the channels that have subscribers, with who is subscribed, which of them are not running, and which one is you.

Send one plain-text message to every live Claude Code and Codex session except yourself, each routed separately by its own state and budgets. It is for announcements, so it is never urgent: fyi (the default) is batched until each session is idle, normal reaches a session at its next tool call unless it was interrupted a lot lately. To reach one session or a group, use send_message or a channel instead.

Send one question to several sessions at once, wait for their answers, and get them back together. to lists session names or refs, and "#channel" names to ask a channel's subscribers; at most 16 sessions. Each message names the answer tool and the ask id. The call returns when all have answered or after timeout_seconds, and says who did not answer. With pick "best" the smart-routing model, if your user turned it on, also says which reply answers best and how likely each is; that is its opinion, every reply is still shown, and the question and replies are sent to that model. A Claude session cannot ask Claude sessions this way: they are listed so you can use SendMessage.

Answer a question another session sent you with ask (its message names an ask id). The asker receives your answer together with the others. Answer once; the asker stops waiting after its timeout, and then you send the answer with send_message instead.

Tell agentsocks whether a message another session sent you was worth the interruption: useful-now (right to reach you now), could-wait (fine, but it could have waited until you finished) or noise (not worth reading). Ratings stay on this machine. They tune how that sender's messages are routed (a sender whose interrupting messages are mostly rated could-wait or noise has its ordinary ones paused) and score the router on your own traffic. Without message_id or from it rates the latest message you received.
