# @add-ideas/toolbox-shell-react ```tsx import { AppShell } from "@add-ideas/toolbox-shell-react"; import "@add-ideas/toolbox-shell-react/styles.css"; setHelpOpen(true) }}> ; ``` `AppShell` discovers `?toolbox=...` or ``, but continues in standalone mode if context is absent, unavailable, cross-origin, or invalid. Its app switcher is exposed as the accessible navigation landmark `Toolbox applications` and all destinations use ordinary document navigation. The shared top bar also exposes Help, Gitea source, light/dark/system personalization, and Apps controls. `ToolboxHeader` is exported separately for custom shells.
