1313Whether Claude replies to a message without an @-mention depends on where you send it.
1414
15| Where you write | Replies without an @-mention? |
16| :---------------------------- | :-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
17| A DM with Claude | Always. Every message is addressed to Claude already |
18| A thread Claude is already in | Yes, unless you've [quieted the thread](#quiet-one-conversation). Once Claude has joined, every reply there reaches it without another mention |
19| A channel, top-level | Sometimes. [What Claude does with a channel message](#what-claude-does-with-a-channel-message) describes how it decides. Include `@Claude` to guarantee a reply, or [turn unprompted replies off](#quiet-the-whole-channel) |

20| A message another app or bot posted | No guaranteed reply. Claude reads it as context. `@Claude` in a bot's message doesn't wake a quiet channel; in an active channel Claude may pick it up. See [Messages from other apps and bots](#messages-from-other-apps-and-bots) |

2122When you @-mention Claude in a channel, it reacts to your message with an emoji within a few seconds to show that it picked the message up. It then answers in a thread under your message, or starts a [working session](/docs/claude-tag/concepts/how-it-works) in that thread when the request needs investigation, tools, or a longer exchange. Once a working session starts, Claude shows an "is thinking…" line under your message. A reaction with no line under it means Claude picked your message up and is either still deciding or answering directly in the thread, not that it missed you.

3637## Turn automatic replies on or off

38The **Respond automatically** setting controls whether Claude replies to a channel's messages without an @-mention. Each channel has its own. When it's on, Claude may reply to a message it judges warrants one, as [What Claude does with a channel message](#what-claude-does-with-a-channel-message) describes. When it's off, Claude replies in that channel only when someone @-mentions it.

41The setting is on by default, so a channel Claude was just added to replies without @-mentions from the start.
42
43Each channel has its own copy of the setting, and there is no workspace- or organization-wide version. To make Claude mention-only across many channels, turn it off in each one.
44
4045All three places below change the same setting, so a change you make in one appears in the others.

4449| In Slack | Ask Claude in the channel, for example "@Claude only respond in this channel when someone @-mentions you" or "@Claude respond to messages here even when nobody mentions you." Claude confirms the change. |
45| The channel's Configure page | Open the **Configure** link in the footer of any Claude reply and switch the **Respond automatically** toggle. See [Configure Claude for a channel](/docs/claude-tag/users/good-habits#configure-claude-for-a-channel). |
50| The channel's Configure page | Open the **Configure** link in the footer of any Claude reply in the channel and switch the **Respond automatically** toggle. See [Configure Claude for a channel](/docs/claude-tag/users/good-habits#configure-claude-for-a-channel). |
4651| The Claude Tag admin page (admins only) | At [`claude.ai/admin-settings/claude-tag`](https://claude.ai/admin-settings/claude-tag), on the **Slack** tab under **Claude Tag's access**, open the channel's scope and switch **Respond automatically** in its **Advanced** settings. |

4853The setting covers the channel's messages, not DMs. To quiet a single thread instead of the whole channel, [ask Claude in that thread](#quiet-one-conversation).
54
55Until Claude has joined a channel, you see "@-mention Claude in this channel to activate" in place of the toggle on the Configure page and the admin page. You see the same line in a channel shared across workspaces that all belong to your Claude organization, because Claude runs there with your organization's default settings only. [Messages that never get a reply](#messages-that-never-get-a-reply) covers shared channels in more detail.

57## Messages from other apps and bots
58
59Claude reads a message that another Slack app or bot posted as channel context, but a bot's message never gets the guaranteed reply that a person's @-mention gets. If the channel's [Respond automatically](#turn-automatic-replies-on-or-off) setting is off, or Claude has [stopped reading the channel](#when-claude-stops-reading-a-channel), a bot's `@Claude` doesn't wake it. In a channel where Claude is active, a bot's `@Claude` reaches Claude as a hand-off it may pick up or leave, and it may answer in a thread. Claude treats alerts an integration posts, messages a Slack workflow posts, and messages from any other bot the same way.
60
61Because Claude reads those messages, when a person asks about an alert a bot posted, Claude can answer from it. To have Claude act on what an integration posts, mention it in the channel or in the message's thread. For example, reply to a bot-posted alert with `@Claude triage this`. To have Claude check the channel on a schedule and post what needs attention, set up a [routine](/docs/claude-tag/users/proactivity).
