The session area

The session area, right of the sidebar, shows the selected session: the top bar, its terminal and your last message to it. The diff and preview panes open beside the terminal.

The top bar

The top bar of a waiting session

On the right, the git change counts open the diff, and toggles such as Auto start apply to draft, bug and refine sessions. Then its actions, shown only when they apply:

• Add agent (⌥AltZ) starts another agent in the same working copy, with a prompt you type, so it picks up the work in progress. It is offered while the session is still working.
• VS Code (⌥AltX) opens the session’s working copy in VS Code.
• Restart ends the agent and resumes its conversation in a fresh process, after asking. Retry reruns a run session, or an assist command that couldn’t be restored.
• Star pins the session to the top of the sidebar. For a backlog run, the star belongs to the item, so it carries over to the item’s next session.
• Done (⌥AltC), on a backlog item’s session, marks the item done and ends the session after asking. Hold ⇧Shift as you click it or press Enter to skip asking.
• × closes the session, as on its card.

Pull request, review and server buttons appear for sessions that have them.

Commands an agent runs to act on its own card, such as /close and /rename, are on Session commands.

The terminal

The terminal is the agent itself, such as Claude Code, running live. You give it prompts, answer its questions and approve its permission requests here, as you would in Claude Code in your own terminal. For a run session, it shows the command’s output.

• ⌘CtrlC copies the selected text. With nothing selected, it reaches the session as an interrupt.
• ⌘CtrlV pastes.

Your last message

Your last prompt to the session sits over the top-left of the terminal, cut to one line. Hover to read all of it, or click to pin it open until you press Esc or click elsewhere. Scrolling over it steps back through your earlier prompts, with a counter showing which one you’re on.

Transcripts

Clicking an entry on the sidebar’s History tab shows its transcript here in place of the terminal.
