 ### Restrict guest channels
 
-By default, Claude is disabled in any channel that includes a Slack guest. The **Allow Claude to work in channels with guests** setting changes that per scope. It's at [`claude.ai/admin-settings/claude-tag`](https://claude.ai/admin-settings/claude-tag), on the **Slack** tab under **Claude Tag's access**, in the scope's collapsed **Advanced** section, and it has three values:
+By default, Claude is disabled in any channel that includes a Slack guest. To allow it there, set **Allow Claude to work in channels with guests** to **Allow** for the scope covering the channel; **Restrict** (the default) keeps it off wherever a guest is present. The setting is at [`claude.ai/admin-settings/claude-tag`](https://claude.ai/admin-settings/claude-tag), on the **Slack** tab under **Claude Tag's access**, in the scope's collapsed **Advanced** section.

-| ---------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
-| **Restrict** (default) | Doesn't reply. When someone mentions it, Claude posts a short notice that it doesn't respond in channels that include guests, with a link to this setting.                                                                                                                                                                                    |
-| **Channel only**       | Replies, but while a guest is present it runs with channel-only access. Bundles, connectors, and instructions from the workspace or from **Default Slack access** don't reach the channel, and neither do repositories, memory, or skills. The channel's own instructions and any access bundle attached directly to the channel still apply. |
-| **Allow**              | Replies with the full access the scope gives it, as in any other channel.                                                                                                                                                                                                                                                                     |
+**Allow** applies to every guest channel the scope covers, and guests in those channels can see Claude's replies and interact with it. To open one channel rather than a whole workspace, set it on the channel's own scope.
 
-A channel without its own value shows **Inherit** and takes the value from its workspace, or from **Default Slack access**. Changing this setting requires an organization owner. The setting applies to every guest channel the scope covers; to open one channel rather than a whole workspace, set it on the channel's own scope.
+**Allow** controls whether Claude replies, not what it can search. Workspace search is unavailable in any channel that includes a guest, even when the setting is **Allow**. Search results could include content from channels the guests can't see, the same reason Claude doesn't search private channels. To run a search that covers the workspace, ask from a channel without guests.
 
-Under every value, guests in the channel can read what Claude posts there. In any channel that includes a guest, even under **Allow**, Claude won't search the workspace, look up people or channels, or read channels other than the one it's in, because the results could include content the guests can't see in Slack. That is the same reason Claude doesn't search private channels. To do any of that, ask from a channel without guests.
+### Externally shared channels
 
-#### How Channel only works
+Claude doesn't operate in Slack Connect channels, the ones shared with another company. It's off in those channels regardless of scope or bundle, and this isn't configurable.
 
-**Channel only** lets a team keep using Claude in a channel shared with contractors, clients, or agency partners without exposing the rest of the organization's setup to that conversation. While a guest is in the channel, Claude keeps what is set on the channel itself and drops what it would inherit:
-
-* No [access bundles](/docs/claude-tag/admins/attach-to-scope) from the workspace or from **Default Slack access**. A bundle attached directly to this channel's scope still applies, with its connections, instructions, and plugins, so attach to a guest channel only what you're comfortable having used in front of guests.
-* No repositories, including any in a bundle attached to the channel, and no connectors set directly on the channel.
-* No instructions set on the workspace or the organization. Instructions set on the channel itself still apply.
-* No memory, including this channel's own, and no skills.
-* No [environment set on the scope](/docs/claude-tag/admins/customize#configure-the-environment-for-a-scope). The session runs on the standard environment, so that environment's setup script, environment variables, and network access level don't apply while a guest is present.
-
-Claude decides this when a conversation starts. When no guest is in the channel, new conversations get its usual full access, as under **Allow**. A guest can talk to Claude by mentioning `@Claude` or by replying in a thread Claude started after a guest was in the channel, and Claude answers them. In a thread Claude began before the first guest joined, Claude stops replying while a guest is present, and a guest who writes there gets the same notice as under **Restrict**; start a new thread instead. While a guest is present, Claude replies only to mentions and to threads it's already part of; it doesn't pick up other channel messages on its own, even where [**Respond automatically**](/docs/claude-tag/users/when-claude-responds#turn-automatic-replies-on-or-off) is on. A guest can't approve a tool or permission request, or restart, mute, fork, or stop the session. If a guest clicks approve, nothing is granted and a workspace member has to ask Claude again.
-
-Treat a channel's instructions, and the instructions in any bundle attached to the channel, as visible to everyone in that channel, including guests. Under **Channel only** they shape replies that guests read and take part in.
-
-**Channel only** takes effect where the **New** version answers. On a scope where **Legacy** answers, a channel that includes a guest is treated as **Restrict**.
-
-<a id="externally-shared-channels" />
-
-### Slack Connect channels
-
-In a Slack Connect channel, one shared with another company, Claude treats everyone from the other company as a guest, and the [guest setting](#restrict-guest-channels), **Allow Claude to work in channels with guests**, decides whether it replies. Under **Restrict**, the default, Claude stays silent and posts no notice, unlike in a channel with a Slack guest. To let Claude answer, set the guest setting to **Channel only** on the channel's scope, or on a scope it inherits from; **Allow** behaves the same there, because in a Slack Connect channel Claude only ever runs with [channel-only access](#how-channel-only-works).
-
-When Claude replies in a Slack Connect channel:
-
-* People from the other company can ask it by mentioning `@Claude` or replying in a thread it's already in. When the [restriction toggle](#restrict-who-can-use-claude) that limits Claude to your organization's members is on, Claude doesn't answer them. Whether or not the toggle is on, they can't approve a tool or permission request.
-* Claude doesn't search your workspace, look up people or channels, read other channels, or use memory. Of the [commands](/docs/claude-tag/users/commands), your organization's members can use only `!help`, `!mute`, and `!unmute`; restarting or forking a session isn't available, and neither are routines.
-* Claude replies only to mentions and to threads it's already in, even where [**Respond automatically**](/docs/claude-tag/users/when-claude-responds#turn-automatic-replies-on-or-off) is on. It reads the rest of the channel as context, including what the other company's people and apps post, but never answers their apps or bots.
-* You can't create a scope for a channel that's already shared; the console refuses it. A scope created before the channel was shared still applies, with its instructions and any bundle attached directly to it, so treat both as visible to the other company.
-* Everyone in the channel reads what Claude posts.
-* Claude stops replying in a thread it was in before the channel was shared, and posts a notice asking for a mention in a new thread.
-
-The guest setting controls only your organization's Claude. If the other company also uses Claude Tag, their settings decide whether their Claude answers in the channel, and you can't turn theirs off from your side. Claude never answers the other company's Claude.
-
-On Enterprise Grid, when Claude is installed at the organization level rather than per workspace, it replies only in Slack Connect channels that one of your own workspaces created. In a channel the other company created, it stays silent and posts no notice.
-
 ### Channels shared across workspaces in your Enterprise Grid
 
 What happens in a channel shared across more than one workspace inside your Enterprise Grid depends on whether every workspace in it is connected to the same Claude organization.
 
-When the workspaces all belong to your one Claude organization, Claude replies in the channel, but only with the access and settings on your organization's [Default Slack access](/docs/claude-tag/admins/attach-to-scope) scope. Bundles, instructions, and memory set on a workspace or on that channel don't reach it. Claude posts a notice in the thread explaining this, about once a month per channel at most rather than on every reply. Where guest access is **Restrict** or **Channel only**, the [guest check](#restrict-guest-channels) still runs first and can refuse the reply.

-**Allow Claude to work in channels with guests** is set to **Restrict** or **Channel only** for this channel's [scope](/docs/claude-tag/concepts/glossary#scope), so Claude checks the channel for guests before replying, and this install predates the `users:read` permission that check needs.

 Either fix works:
 
 * Remove the guests from the channel, or move the conversation to a channel with no guests; this changes no settings, so no other channel is affected.
-* Or change **Allow Claude to work in channels with guests** for the scope covering this channel; changing it needs an organization owner. **Channel only** restores replies while keeping Claude to the channel's own instructions and access. **Allow** gives guests the full access the scope has. The setting is at [`claude.ai/admin-settings/claude-tag`](https://claude.ai/admin-settings/claude-tag), on the **Slack** tab under **Claude Tag's access**, in the scope's collapsed **Advanced** section. Either value applies to every guest channel that scope covers; to limit it to one channel, set it on the channel's own scope. See [restrict guest channels](/docs/claude-tag/admins/restrict-access#restrict-guest-channels) for what each value exposes.

 **What it means**
 
-By default, Claude is off in Slack Connect channels, and it posts no notice there. A Claude organization Owner turns it on with the [guest setting](/docs/claude-tag/admins/restrict-access#restrict-guest-channels), after which Claude replies with [channel-only access](/docs/claude-tag/admins/restrict-access#how-channel-only-works). If the setting is already **Allow** or **Channel only** and Claude still doesn't answer, one of two things is likely:
+Claude doesn't operate in Slack Connect channels, the ones shared with another company. This holds regardless of admin settings. Messages there get no reply. See [externally shared channels](/docs/claude-tag/admins/restrict-access#externally-shared-channels).
 
-* The organization that runs Claude restricts it to its own members, and you're on the other side of the channel.
-* That organization installed Claude at the Enterprise Grid organization level, and the other company's workspace created the channel.
-
-See [Slack Connect channels](/docs/claude-tag/admins/restrict-access#externally-shared-channels).
-
-If the mention gets the notice "This channel is now shared with another organization through Slack Connect, so this thread's earlier session can't continue here," the thread started before the channel was shared. Mention `@Claude` in a new thread.
-
 A channel shared across workspaces inside your Enterprise Grid isn't silent; what happens there depends on how those workspaces connect to Claude. When every workspace in the channel belongs to your one Claude organization, Claude answers, but with only your organization's default access and settings, so a repository or an instruction set up for that channel doesn't apply. A notice in the thread points this out from time to time. When the workspaces are connected to different Claude organizations, you see "This channel is shared among several Claude workspaces, so Claude cannot respond here" instead of an answer.
 
 Where guest access is restricted, you may first see "This channel is shared across multiple workspaces, and Claude can't verify whether it includes guests, so Claude can't respond here." If you ask Claude from another conversation to act in one of these channels, such as posting a message there, you see a reply that ends "Claude isn't available in channels shared across your Enterprise Grid".

 * Remove the guests from the channel. In Slack, open **Channel details** → **Members** and filter by "guests"; guests show a **guest** badge on their Slack profile.
 * Move the conversation to a channel with no guests.
-* Ask an admin of your Claude organization to change the guest setting for this channel, and send them [the guest access setting](/docs/claude-tag/admins/restrict-access#restrict-guest-channels). They can let Claude reply with only the channel's own setup, or with full access. If you don't know who your organization's admins are, ask whoever set Claude up in your workspace.

 The guest access setting restores replies, not workspace search. Claude can't search the workspace from a channel that includes guests, even when it's allowed to respond there. Removing the guests or moving the conversation to a channel with no guests restores search as well.

 * **Channels shared across workspaces connected to different Claude organizations.** Every workspace where Claude runs is connected to a Claude organization, the account a company sets up for Claude.

 A private channel is readable only from inside it. Inviting Claude lets it work in that channel, but Claude can't read the private channel's messages from any other channel or DM. To ask about a private channel, ask in that channel.

 2. Keep the channel private. A bundle on a public channel [grants its access to anyone who joins](/docs/claude-tag/admins/attach-to-scope#attach-to-a-channel).
