    Thread Conversations

    Threads let you branch off from a message in the main chat for a focused side conversation. They keep the main channel clean while letting you dig deeper into a specific topic. Any message in a channel can become the starting point for a thread.

    Start a Thread

    Hover over any message in the main chat. A small action bar appears in the top-right of the message with quick options. Click the Reply in thread icon (a curved arrow) to open the thread panel on the right side of the screen, with the parent message preview at the top.

    You do not need to create a thread explicitly. The first reply you send creates the thread automatically. Type your reply in the input field at the bottom and press Enter or click the send button.

    Reply to a Thread

    The reply input supports the same features as the main message input: text, @-mentions, file attachments, and drag and drop. Replies appear in the thread panel and stay out of the main channel.

    Choose Who Sees Your Reply

    Threads have the same audience toggle as the main composer. Click the Everyone pill below the reply input to switch to Humans Only mode for that thread.

    In Everyone mode, both people and specialists can see and respond to your replies. In Humans Only mode, specialists are paused — handy for a quick side conversation with teammates without an AI chiming in.

    The toggle is per-thread, so you can run quiet threads alongside specialist-led ones in the same channel.

    See Replies Back in the Channel

    Once a thread has at least one reply, an indicator appears under the original message in the main chat showing how many replies the thread has and who has participated. Click the indicator to open the thread panel and see all replies.

    The indicator shows:

    • Participant avatars. Up to three stacked profile pictures of people who have replied.
    • Reply count. The total number of replies, like "2 replies".
    • Last reply time. When the most recent reply was posted.
    • Status dot. A colored dot showing the execution state of any specialist activity in the thread. Green means done, yellow means in progress, red means an error, gray means idle.
    • Unread badge. A count of new replies you have not read yet.

    Resize the Thread Panel

    The thread panel opens as a resizable side panel alongside the main chat. Drag the divider between the main chat and the thread panel to adjust the width of each side. Each side has a minimum width of about a quarter of the screen.

    Specialist Reasoning and Tool Calls

    When a specialist replies in a thread, you may see two extra sections inside its message:

    • Reasoning. A collapsible block showing the specialist's chain of thought. Click to expand and read how the specialist worked through the problem.
    • Tool calls. A collapsible block listing every tool the specialist used while preparing the response — searching code, reading files, running commands, looking up tasks. Each tool call shows its inputs and outputs so you can verify the work.

    These sections appear automatically when a specialist's response involves reasoning or tool use. They are collapsed by default to keep the reply readable.

    Empty Threads

    When you open a thread that has no replies yet, you will see an empty state with a message icon and the text "No replies yet. Be the first to reply to this message." along with the reply input field at the bottom.

    Read-Only Threads

    If you are not a member of the channel, you can still view threads but cannot reply. The input area is replaced with a notice that reads "Read-only thread. Join this channel to reply."
