- The account rows My Agents, Usage and API Keys in `NavbarUser` have no handler, and `USER` is sample data

## When not to use

- A sidebar-free page layout with a tab track and a count badge header: use [Top Navbar Admin](https://web.dev.reui.io/blocks/application/app-shell/app-shell-30.md) (`get_block("app-shell-30")`)
- A library table filtered by status tabs and a multi-field filter popover: use [Automation Library](https://web.dev.reui.io/blocks/data-grid/filtering/data-grid-filtering-2.md) (`get_block("data-grid-filtering-2")`)

## About Navbar blocks

### When to use

- The top bar of a signed in product, with a breadcrumb or switchers, search, alerts, avatars or a user menu
- An editor toolbar with a back or close button, the page name and its run, publish or submit action
- A marketing site header with mega menu panels of linked pages and a Get Started button

### When not to use

- A whole product layout with a side rail, a header and the content area together: use the [App Shell blocks](https://web.dev.reui.io/blocks/application/app-shell.md)
- A keyboard palette that lists, groups and filters results as you type: use [Command](https://web.dev.reui.io/components/command.md) (`get_component("command")`)
- The account settings page a user menu opens, with team, billing and API key forms: use the [Profile blocks](https://web.dev.reui.io/blocks/application/profile.md)

### Agent notes

- `Navbar` takes no props, so every label, person and option it shows is fixed in the block; lift them into props to reuse it
- No button, link or menu item routes or calls an API; add an `onClick` or a real `href` where each one should go
- Each page.tsx adds only demo padding or dashed placeholder boxes around `Navbar`, none of which belongs in your layout

Every ReUI item has a twin like this one; the index is https://web.dev.reui.io/llms.txt. Agents with the ReUI MCP (https://web.dev.reui.io/docs/mcp) get the same guidance from the getters named above.
