Cmux Workspace

This skill teaches Claude to work inside the cmux workspace that called it, without hijacking your focus or spawning surprise splits in the wrong window. It enforces a "caller context first" rule using `CMUX_WORKSPACE_ID` and `CMUX_SURFACE_ID`, so automation stays scoped even when you're looking at a different tab. The big win is the non-disruptive policy: no speculative `select-workspace` or `focus-pane` calls, additive layout commands that create panes with content in one shot, and a right-side helper pane pattern that reuses space instead of cluttering your workspace. If you run agents in the background or multi-task across cmux workspaces, this keeps the automation polite and the layout predictable.
