cmux-workspace

# cmux Workspace Scope work to the cmux workspace that invoked the agent. - **Window**: a macOS cmux window. - **Workspace**: a sidebar entry. The UI calls it a tab; CLI/socket APIs call it a workspace. - **Pane**: a split region inside a workspace. - **Surface**: a tab inside a pane, terminal or browser. - **Panel**: internal content type inside a surface. Prefer CLI surface commands over panel internals. ## Default rule Scope actions to the current caller workspace unless the user explicitly asks for another workspace, another window, or global state. Do not assume the visually focused workspace is the right target: an agent can run in one workspace while the user looks at another. ```bash printf 'workspace=%s\nsurface=%s\nsocket=%s\n' \ "${CMUX_WORKSPACE_ID:-}" "${CMUX_SURFACE_ID:-}" "${CMUX_SOCKET_PATH:-}" cmux identify --json ``` `CMUX_WORKSPACE_ID` is the default workspace anchor and `CMUX_SURFACE_ID` the default caller terminal anchor. If they are missing, fall back to `cmux identify --json` and say explicitly that you are using the currently focused context. ## Non-disruptive automation Treat layout and focus as separate concerns. `select-workspace`, `focus-pane`, `focus-panel`, and focus-changing `tab-action` verbs are user-affecting actions, like clicks. Never call them speculatively, even inside the caller's own workspace, since the user may be looking elsewhere. Build layout additively in one shot, using commands that create a pane already populated wit...
