Shadcn App Shell 34 Block

For AI Agents

Hand your agent this brief or the ReUI MCP, not a screenshot. Installs with a ReUI Pro or Ultimate license.

Best for: A purchase order queue with 3 linked check markers per order, Review, Ready and Overdue filters and an AI advisor citing AP policies

When to use

The outer layout of a multi page product: the navigation around its content area
Dashboards and admin consoles that switch between workspaces or projects

When not to use

A general project list sidebar with progress rings and a spending limit card: use the Project Tracker Sidebar block
A new invoice to draft, with editable line items and a live tax total: use the Invoice Creator block
One overview page of stats, charts and tables inside your own layout: use the Dashboard blocks
A top bar on its own, above a page layout you already have: use the Navbar blocks

Agent notes

Replace ORDERS, CHECKS and MORE_ITEMS in data.tsx; the count line reads a fixed QUEUE_TOTAL, and no row pick changes the skeleton WorkspaceContent
composeReply matches keywords to canned REPLY_LIBRARY answers and Escalate only appends handoffOpenedText; wire both to your model and case queue
Upload New, New 3WIM and the CheckMenu items only fire a sonner toast; rail Help and Settings and the UserMenu rows besides Theme have no handler
Shells that switch themes call useTheme from next-themes, so the app must mount the next-themes ThemeProvider
