Channels are the public conversation spaces of a workspace: project threads, team coordination, decisions in progress, and handoffs. Direct messages cover the same ground when a conversation should stay between two participants, such as a private question to Orca.
Create And Organize Channels
Create a channel from the Channels + action in the sidebar. Keep names short and searchable, using lowercase letters, numbers, hyphens, and underscores. Add a purpose when the channel has a clear scope; people and agents both read it as context.
Channel settings live in the row menu. From settings, members can refine the name and purpose, join or leave non-default channels, and add or remove people and agents from the member panel. Adding a new server-managed agent to the workspace is admin-only, but an existing agent can be added to a channel from these settings.
Except for #general, ordinary channels can be deleted. Deleting a channel removes its message history, so preserve durable decisions in the Wiki first.
Write Messages With Links
Channel messages use the same Markdown body as wiki pages and DMs, documented in full under Syntax:
**bold**,*italic*, headings, lists, task lists, code, and quotes.- Wiki page links such as
[[Launch Plan]]or[[Launch Plan|launch plan]]. - Workspace file links such as
[[/briefs/q2.pdf]]. The leading slash is required. - Channel links such as
#general. - External URLs, which can expand into link previews when metadata is available.
Autocomplete, Dragging, And Editing
In the composer, type @ for people and agents, [[ for wiki pages, [[/ for workspace files, and # for channels. Dragging a wiki or file item from the sidebar into the composer inserts the matching link; dragging in local operating-system files uploads them as workspace files and inserts links to them.
Editing your own message uses the same composer and autocomplete. Plain Enter saves the edit, Shift+Enter or another modified Enter inserts a newline, and Escape cancels after dismissing any open autocomplete suggestions. Editing the text does not replace or remove existing attachments.
Reactions And Message Links
Hovering or focusing a message reveals actions such as emoji reactions, copy message link, and selection-based actions. Message links cite a prior decision from a wiki page or another channel.
Reactions are visible to the conversation participants. A person can add multiple different emoji reactions to a message, but pressing the same emoji again removes that person's reaction.
Calling Agents In Channels
Mention an agent with @Agent Name when you want a channel answer; the agent must be a member of that channel. If Orca does not answer, check whether the message actually mentioned @Orca, whether Orca is in the channel, and whether the message was directed to a person instead. See Agents for mentions, jobs, and token limits, and Orca Capabilities for what Orca can read and produce.
Steering Or Interrupting A Running Agent
If an agent is working and you want to change direction, send another message in the same conversation. The running response is interrupted and the new message becomes the next instruction. To stop explicitly, use the interrupt control on the agent progress row.
