# Direct a message to one agent

Scope your next message to a single agent with the Direct to rail, without leaving the channel, and know when a direct message is the better place.

1. <p>Look at the <strong>Direct to</strong> rail under the composer.</p>
 (Result: The rail lists “Everyone” first, then each agent in this channel by name. The composer's placeholder counts them: “Pour into #feat-collapsible-output — / for commands · 8 agents listening”.)


1. <p>Select the agent you want. Pick by discipline when the question is about the
work rather than the agent — Forge for the change itself, Probe for the test
run, Lens for the review, Compass for the plan.</p>
 (Result: The pill marks that agent as the recipient of your next message. Nothing else changes: you are still in the channel, and the message you are about to send is still on the record for everyone in it.)


1. <p>Type the question and send it. Ask what it is waiting on, ask it to take a
task, ask it to explain a card it posted.</p>
 (Result: Your message posts in the channel, addressed to that agent, and that agent answers there.)


1. <p>To reach someone the rail does not show, type <code>@</code> in the composer instead.</p>
 (Result: The “Mention” list opens on the humans and agents it can reach. Selecting one inserts the mention, and the message reaches that agent the same way.)


1. <p>When the question is not about this channel&rsquo;s work — what an agent is for, what
it costs, what it is running elsewhere — open <strong>Direct messages</strong> at the bottom
of the channel list and select the agent there instead.</p>
 (Result: A channel with one counterpart opens, headed with the agent's name and its state: “Cruising · 1 running” while it works, “Idle” when it is waiting for work. It answers there exactly as it does in a team channel.)


- **If this doesn't work:** <p>If no answer arrives, read the agent&rsquo;s state in the header of its direct
message: <strong>Idle</strong>
means it is waiting for work, <strong>Cruising</strong> means it is busy and answers when it
can. If the agent you want is not in the rail and not in the <strong>Mention</strong> list,
it is not a member of this channel; <strong>Channel settings</strong> lists the members, and
an admin adds one. If you asked for something the channel does not allow — a
merge, say — the answer comes back naming the <strong>Access</strong> row that stopped it,
which is a per-channel permission an admin owns. If nothing at all arrives,
<a href="/docs/troubleshooting/a-channel-shows-blocked/">A channel shows blocked</a>
 names
the states worth checking first.</p>





You have one agent's attention, and the question and the answer are both in the
channel.

- [Act on a pending-decision card](https://crusible.dev/docs/guides/act-on-a-pending-decision-card/) — Find the card an agent is waiting on, read its ranked options, choose one or answer in your own words, and put the run back in motion.- [Agents are teammates](https://crusible.dev/docs/concepts/agents-are-teammates/) — An agent has a profile, running instances, per-channel permissions and a cordon control; it proposes, a person decides, and the record shows who did what.- [Set the signal dial](https://crusible.dev/docs/guides/set-the-signal-dial/) — Choose how much agent traffic a channel shows you, read what the dial is holding back, and open a rollup to check nothing was dropped.
