Superset Pane Layout

Script the tabs and split panes of a workspace with superset panes. Commands go to the host, then to the desktop app, which applies them to the live layout the user is looking at. Every change is visible immediately, so build layouts the user asked for and clean up what you open.

Establish the control surface

  1. Run superset schema 2>/dev/null | jq -re '.commands[] | select(.path==["panes"]) | .commands[].path[1]' || superset panes --help and require list, split, new-tab, resize, equalize, move, swap, focus, and close. panes is new in CLI 1.38.0. If it is missing, run superset update and recheck. The app-bundled CLI (~/.superset/bin/superset) updates only with the desktop app, so if it still lacks panes, updating the app is the fix.
  2. Resolve the workspace. Inside a workspace, use $SUPERSET_WORKSPACE_ID; otherwise superset workspaces list --local --json and pick the target.
  3. Panes live in the desktop app. A host with no desktop attached (a standalone superset start) has no panes, and an older desktop app answers "This host is too old for superset panes". Surface either rather than retrying.

Read the layout

superset panes list --workspace "$WS" --json

The result has activeTabId and tabs[]. Each tab has layout, a split tree of { type: "split", direction, ratio, first, second } and { type: "pane", paneId } nodes, plus a flat panes[] with each pane's kind (terminal, chat-v3, browser, …), terminalId, active, and the agent running in it with its state. row splits sit side by side and column splits stack; ratio is the first child's share.

Inside a workspace, the pane you are running in is the one whose terminalId equals $SUPERSET_TERMINAL_ID:

ME=$(superset panes list --workspace "$WS" --json \
  | jq -r --arg t "$SUPERSET_TERMINAL_ID" '.tabs[].panes[] | select(.terminalId==$t) | .id')

Change the layout

Every mutating command returns the new pane or tab ID plus the full updated layout, so chain commands from its output instead of listing again. Read IDs with --json | jq -r .paneId (or .tabId, .terminalId); --quiet does not reduce these results to an ID.

Goal Command
Split a pane, new terminal in the new half panes split --workspace $WS --pane P --direction right|left|down|up [--command CMD]
Open a tab with a terminal panes new-tab --workspace $WS [--command CMD]
Show an existing terminal instead add --terminal <terminal-id> to split or new-tab (not with --command)
Set a pane's share of its split panes resize --workspace $WS --pane P --ratio 0.05–0.95
Even out every split panes equalize --workspace $WS [--tab T]
Exchange two panes, even across tabs panes swap --workspace $WS --pane A --with B
Move a pane beside another panes move --workspace $WS --pane P --to Q --direction right|left|down|up
Move a pane into a tab of its own panes move --workspace $WS --pane P --new-tab
Bring a pane and its tab to the front panes focus --workspace $WS --pane P
Close a pane panes close --workspace $WS --pane P [--keep-terminal]

Behavior to rely on:

  • Only focus moves focus. split and new-tab add panes without taking the user away from what they are looking at; follow with focus only when the user should see the new pane now.
  • --command types the command into the new terminal's shell. When it exits, its output stays on screen above a prompt, so one-shot commands need no wrapping. A display that should keep refreshing needs its own loop (while true; do clear; …; sleep 2; done).
  • close ends the pane's terminal, as the close button in the app does. Pass --keep-terminal to keep a long-running process alive in the background and reattach it later with --terminal.
  • move closes a tab it leaves empty.
  • A split always halves the pane it splits. Splitting one pane repeatedly gives 50/25/12.5 shares; build the tree, then equalize once.
  • If the desktop app does not confirm a split or new-tab in time, the CLI keeps the terminal it created and says so. Check panes list before retrying, or the retry opens a second pane.

Read what a pane shows

superset terminals read --local --workspace $WS --terminal <terminal-id> --json returns the screen text of a terminal pane, which confirms a command started and shows its output. Pass --local (or --host <id>); without it the CLI looks for a cloud workspace.

Layout recipes

Side by side with the user's pane, tests on the right, a watcher below them:

WS=$SUPERSET_WORKSPACE_ID
R=$(superset panes split --workspace $WS --pane "$ME" --direction right --command 'npm test -- --watch' --json)
TESTS=$(jq -r .paneId <<<"$R")
superset panes split --workspace $WS --pane "$TESTS" --direction down --command 'npm run dev' --json >/dev/null
superset panes resize --workspace $WS --pane "$ME" --ratio 0.6 --json >/dev/null

A grid of N panes in a new tab: open the tab, split the first pane right for each column, split each column down for each row, then equalize --tab.

Clean up

Panes you open stay open, and their terminals keep running. When the work is done, or before rebuilding a layout, close what you created: track the pane IDs you made and panes close each one. Do not close panes you did not create unless the user asks, and never close the pane you are running in.
