Channel settings
Manage channel context, privacy, posting access, members, notifications, agent responses, and lifecycle controls.
Each channel has its own configuration in the channel details pane. Open a channel, then open its details or settings view. These controls do not live in the Settings app.
Who can manage a channel
Only channel owners and workspace admins can change channel settings, including context, privacy, post permission, membership, proactive agent responses, and archive or delete controls.
The product uses channel managers as a collective term for:
- Channel owners
- Workspace admins
When the UI or these docs refer to managers, they mean those two groups. Other members can see read-only context and membership information where applicable, but cannot change it.
Channel-specific sections
Some channel types add a section at the top of their details.
- Task appears only in task channels. It shows instructions, schedule, status, run state, and the Whitelist task tools control. See Tasks.
- Email, Messaging, or Slack appears in external channels. This section shows read-only contact and source details for the remote trigger. See External channels.
Channel Context
The Channel Context card contains Markdown guidance for the agent in this channel. Context can provide the background the agent needs when it reads messages or participates in the conversation.
Channel managers can click the card to edit its content in a composer. Other members see a read-only version. When there is no context, the empty state invites managers to add it.
Agent Responses
By default, Endstack can participate naturally in a channel instead of waiting for an explicit @endstack mention on every message. When proactive responses are enabled, the agent may respond when doing so is appropriate. For example, it may answer a question directed at the team, continue a thread it is already helping with, acknowledge a handoff, or contribute when the channel context and recent messages make a response useful.
The setting is phrased as a disable control:
| Control | Effect |
|---|---|
| Disable Proactive Agent Responses | When on, Endstack replies only when a message explicitly mentions @endstack. When off—the default for channels that allow proactive responses—the agent may send a message on its own when appropriate. |
Only channel owners and workspace admins can change this setting.
Privacy
Managers can choose who can discover and join a non-DM channel:
| Option | Meaning |
|---|---|
| Public | Anyone in the workspace can find and join the channel |
| Private | Only invited members can see the channel |
Managers cannot change privacy on preset-locked channels.
Post Permission
Post permission controls who can send messages after they have access to the channel.
| Option | Meaning |
|---|---|
| Everyone | Anyone with channel access can post |
| Admins | Only channel admins and workspace admins can post |
| Specific | Only members selected in an allowlist can post; owners and admins are always allowed |
With Specific selected, use the channel details pane to search for members and add them to or remove them from the allowlist.
Files / Links
The Files / Links section lets members browse media and links shared in the channel.
Files shared in any channel also appear under Shared with me in the desktop Files app. Members can reopen those files without returning to the channel thread. See Team Drive & sharing.
Members
The members section lists everyone who currently belongs to the channel. Channel owners and workspace admins can use Add and Remove when member changes are permitted. Roles continue to follow the applicable workspace and channel membership rules.
Notifications
Turn on Mute notifications to silence notifications from this channel. Workspace-wide notification scope still applies; see Notifications.
Danger Zone
When lifecycle controls are available, managers can Archive or Delete a channel from the Danger Zone. These actions are not shown for direct messages or preset channels.
