36  Customize Claude Tag

Claude Tag is customized per channel and workspace (a scope), not per user. See what admins set in claude.ai, what anyone can change from the channel, and what stays fixed.

export const BetaNote = () => Claude Tag is in public beta. Features and behavior described here may change before general availability.;

Claude Tag’s behavior is shaped by four layers, each set in a different place:

Layer What it is Who sets it Where
Connections Credentials for the systems Claude can reach (GitHub, Drive, Datadog, your APIs) Owner Access bundles
Plugins and skills Instructions that teach Claude how to use a tool or follow a process. A plugin bundles one or more skills. Owner Bundle Plugins tab or a skills repository
Custom instructions Standing guidance read in every session at a scope (team conventions, output formats). Outranks channel memory. Owner for any scope; channel members for the channel scope, from the Configure page Per-scope instructions
Channel memory Facts Claude saves while working in a channel Anyone in the channel By telling Claude

Connections and plugins decide what Claude can do; instructions and memory shape how it does it.

36.1 Settings admins control

Access and organization-wide behavior are set at claude.ai/admin-settings/claude-tag, per scope (a scope is a channel, a workspace, or your whole organization), so the same agent can work differently in different channels. Most controls below are Owner-only.

Setting What it does More
Custom instructions Standing guidance read in every session on a scope, like team conventions. Outranks channel memory. Add custom instructions
Respond automatically Whether Claude replies to a channel’s messages without an @-mention. Channel members can change it too, from Slack or the channel’s Configure page. Turn automatic replies on or off
Plugins Bundles of skills that teach Claude how to use a specific tool Attach plugins
Connections Which systems it can reach from each channel Add connections
Default model Which Claude model handles sessions in a scope Choose the model for a scope
Auto mode allow rules Actions pre-approved in a scope’s sessions that Claude’s permission checker would otherwise flag or stop Auto mode allow rules
Environment Which cloud environment a scope’s sessions run in. Only organization-shared environments appear in the picker, because Claude runs channel sessions with no user account attached. Channel environment troubleshooting
Claude Tag version Which generation answers (New, Legacy, or Off) in a scope Migrate from the earlier Claude in Slack

36.1.1 Channel connections are separate from personal connectors

An Owner configures Claude’s connections, plugins, and skills, and they apply per scope. They are separate from the connectors, skills, or MCP servers an individual user has set up in their own claude.ai or Claude Desktop account. A user’s personal connectors are not available to Claude in a channel, and the channel’s connections are not listed among that user’s personal connectors in claude.ai.

To give Claude access to a tool that is not in the built-in connection list, including a custom MCP server, see add a custom connection.

36.2 Change behavior from the channel

Everything in the table below is open to channel members, with no admin involved.

To change Say something like More
How Claude formats output “remember for this channel: post reports as a table” Memory
How chatty Claude is “ask before posting anything longer than a screen” Memory
When Claude follows a thread “stay quiet in this thread unless someone tags you” Control when Claude Tag responds
What Claude does on a schedule “every morning at 9, post a digest of open threads” Set up routines
What Claude remembers “what do you remember about this channel?” then correct it Memory

Changes in the table above are saved to channel memory; verify one stuck by asking what it remembers.

Members can also tailor how Claude works in the channel from the Configure link in the footer of any Claude reply. The link opens a claude.ai page where anyone in the channel who is also a member of your Claude organization can edit settings for that channel, unless an admin has restricted editing to admins. The Channel instructions field on that page holds standing guidance that outranks memory. See configure Claude for a channel.

36.3 Choose the model for a scope

Each scope carries a Default model setting in its Advanced section, alongside the environment and guest controls. It sets the model new channel sessions in that scope start on; the options are drawn from the models available to your organization, such as Opus and Sonnet models. A scope without its own setting inherits from its parent, and a channel’s setting overrides its workspace’s. The Inherit option shows which model the scope resolves to.

To keep sessions on a model you chose, set a specific model at the organization scope rather than leaving the setting unset; every scope without an override then follows it.

The setting applies to new sessions; threads already underway keep the model they started with. The footer of each Claude reply in Slack names the model that handled it, so you can confirm what a scope is running.

Channel members can also change the model from Slack, with no admin involved. Asking Claude in a thread switches that thread, and asking it to make a model the channel default changes what new threads in the channel start on. See choose the model Claude Tag uses.

36.3.1 Models your organization allows

Claude Tag’s model lists come from the models your organization makes available for Claude Code, set in the Claude admin console, leaving out any that Claude Tag doesn’t support. A model you see in Claude Code can be absent in Slack for that reason. The allowed list applies in two places.

  • Model lists in Slack. The models Claude offers when someone asks it to switch, and the model selector for direct messages, show only allowed models. Claude declines a request to switch to a model outside the list.
  • Configured defaults. If your organization also enforces the policy on defaults and a workspace or channel’s Default model isn’t allowed by your organization’s Claude Code model policy, Claude declines to start the session and posts a notice in the thread asking the requester to contact an admin. A model excluded by your organization’s plan entitlements works differently. Claude starts the session on a fallback model the plan includes, and declines only when the plan excludes every fallback. The footer of the first reply names the model that served it, so check there to see which model the session started on.

A change to the allowed list applies to new sessions, like a change to the Default model; a thread already underway keeps its model until someone in it asks Claude to switch.

36.4 Auto mode allow rules

Sessions run in auto mode, where Claude’s permission checker reviews each action Claude is about to take and can flag or stop it. When you add an auto mode allow rule to a scope, you pre-approve one action in that scope’s sessions, so Claude runs it there without the checker stopping it. The checker keeps reviewing every other action.

A rule is a plain sentence that describes work you approve in the scope, such as “Deploying to our staging cluster from a session in this channel is a normal, approved workflow.” To add one:

  1. On claude.ai/admin-settings/claude-tag, open the Slack tab under Claude Tag’s access and find the scope you want to change (the organization-wide Slack row, a workspace, or a channel). The Slack row opens as Default Slack access.
  2. Open the scope’s Advanced section and find Auto mode allow rules, below the Default model setting.
  3. Select Add rule and write the rule as one plain sentence.

The rules list has three properties:

  • Limits: a scope holds up to 50 rules, and each rule can be up to 1,024 characters
  • Inheritance: rules you set on a workspace or on Default Slack access (the organization-wide root) carry down to the channels beneath, the way custom instructions stack. A channel’s own rules add to those and never replace them, so put a rule on a single channel’s scope to pre-approve an action there without changing any other channel.
  • Access: you edit the list with the same admin access as the scope’s other Advanced settings

Once you add an allow rule, Claude runs the actions it names in every channel the scope covers without anyone approving them in the moment. Keep each rule narrow: name the tool, the action, and the environment it allows, and put rules that unlock sensitive systems on the narrowest scope that needs them.

36.5 Settings no one can change

  • The Claude app’s name, @-handle, and avatar in Slack are the same in every workspace; there is no rename or rebrand setting.
