# Alert Dialog (Lumen Halo): prompt.md (v1.0.0)

- id: `lumen-alert-dialog` · version 1.0.0 · component · pro (All-Access)
- category: Overlays
- build: Base UI (this item also ships a Radix build)
- install (this build): `npx shadcn@latest add @beautiful-ui-pro/lumen-alert-dialog`
- npm dependencies: @base-ui/react@^1
- registry dependencies: utils, @beautiful-ui/lumen-button, https://beautiful-ui.dev/r/lumen-foundation.json
- docs: https://beautiful-ui.dev/components/lumen-alert-dialog
- The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand.

A decision in smoked glass that won't close by accident. The action is a Lumen Button, so a destructive one keeps its hold-to-confirm. shadcn's Alert Dialog, cut from Lumen glass.

## Build it
- Stack: React 19 (`ref` is a plain prop), TypeScript, Tailwind CSS v4 utilities, a shadcn-initialised project with the `@/*` alias.
- Packages: `@base-ui/react@^1` (Base UI build); `radix-ui@^1` (Radix build).
- Files: `components/ui/lumen/alert-dialog.tsx`; shared code: `lib/beautiful-ui/lumen/portal.ts`, `lib/beautiful-ui/lumen/sound.ts`.
- Registry dependencies, installed with it automatically: shadcn `utils` (cn), `lumen-button`, `lumen-foundation`.
- Builds: separate Base UI and Radix files. Install the one that matches the project (see Install): a free item's bare URL installs the Base UI build of it and its dependencies.
- Exports to keep: `AlertDialog`, `AlertDialogContent`, `AlertDialogHeader / AlertDialogTitle / AlertDialogDescription / AlertDialogMedia`, `AlertDialogFooter / AlertDialogAction / AlertDialogCancel`, and every exported type.
- CSS: the install merges this item's rules (the registry `css` field) into your global stylesheet, in `@layer components`, and adds the lumen foundation (tokens, keyframes, motion levels) once. Nothing to import by hand.
- Re-running `add` (or `--overwrite`) re-applies those rules: put overrides in your own CSS, never in the installed rules.
- Tokens: retheme with the `--lumen-*` custom properties (`--lumen-accent`, `--lumen-accent-text`, `--lumen-bad`, `--lumen-bad-text`, `--lumen-focus`, `--lumen-good`, `--lumen-good-text`, `--lumen-hairline`, `--lumen-ink`, `--lumen-muted-ink`, `--lumen-series-1`, `--lumen-series-2`, `--lumen-series-3`, `--lumen-series-4`, `--lumen-series-5`, `--lumen-series-6`, `--lumen-warn`, `--lumen-warn-text`); this item's CSS also reads `--lumen-font-sans`, `--lumen-radius-k`. Never add Tailwind colour classes inside the component.

```tsx
import { AlertDialog, AlertDialogAction, AlertDialogCancel, AlertDialogContent, AlertDialogDescription, AlertDialogFooter, AlertDialogHeader, AlertDialogTitle, AlertDialogTrigger } from "@/components/ui/lumen/alert-dialog";
```

## Parts

| Part | data-slot | What it is for |
|---|---|---|
| `AlertDialog` | `alert-dialog` | Root. |
| `AlertDialogContent` | `alert-dialog-content` | The glass panel. |
| `AlertDialogHeader / AlertDialogTitle / AlertDialogDescription / AlertDialogMedia` | `alert-dialog-header` | The question. |
| `AlertDialogFooter / AlertDialogAction / AlertDialogCancel` | `alert-dialog-footer` | The choice. |

Style a part with `[data-slot="<slot>"]` selectors or its `className`; keep the attributes when editing.

## Sound
- Keep every `data-slot` and `data-sound` attribute: the sound layer reads them.
- Installing this item adds no audio. Nothing plays until the app mounts `GlassSoundProvider` once (install: `npx shadcn@latest add https://beautiful-ui.dev/r/glass-sound.json`, import from `@/components/beautiful-ui/glass-sound`); `GlassSoundToggle` is its mute control. Without a provider the audio engine never loads.

## Match the original
- Read `components/ui/lumen/alert-dialog.tsx` as the reference implementation before changing or recreating anything, and match it: sizes, colours per theme, motion timings, copy and behaviour.
- If you deviate (a prop you can't honour, a style you changed, a dependency you swapped), say so in your reply, part by part.
- Keep the accessibility contract, the keyboard map and the motion levels listed below.

## Use it when
- alert dialog, confirm, destructive confirm, are you sure, shadcn alert dialog, Lumen
- Confirming something that can't be undone: delete, revoke, overwrite
- A drop-in for shadcn's Alert Dialog: same parts, sizes and media

### Not when
- Anything the user can undo: act, then offer undo
- Forms: use Dialog

## Mistakes
- Say what will happen in the title, not "Are you sure?"

## Usage

```tsx
import { AlertDialog, AlertDialogAction, AlertDialogCancel, AlertDialogContent, AlertDialogDescription, AlertDialogFooter, AlertDialogHeader, AlertDialogTitle, AlertDialogTrigger } from "@/components/ui/lumen/alert-dialog";

<AlertDialog>
  <AlertDialogTrigger>Delete workspace</AlertDialogTrigger>
  <AlertDialogContent>
    <AlertDialogHeader>
      <AlertDialogTitle>Delete this workspace?</AlertDialogTitle>
      <AlertDialogDescription>Dashboards and history go with it.</AlertDialogDescription>
    </AlertDialogHeader>
    <AlertDialogFooter>
      <AlertDialogCancel>Keep it</AlertDialogCancel>
      <AlertDialogAction variant="destructive">Delete</AlertDialogAction>
    </AlertDialogFooter>
  </AlertDialogContent>
</AlertDialog>
```

## Props

| Prop | Type | Default | What it does |
|---|---|---|---|
| `AlertDialogContent size` | `"default" \| "sm"` | `"default"` | sm stacks two equal actions. |
| `AlertDialogAction variant` | `Button variant` |  | destructive keeps Lumen's hold-to-confirm. |
| `AlertDialogMedia` | `ReactNode` |  | An icon tile beside the title. |

## Customising
- Colours: set the `--lumen-*` tokens on `:root`, or on a container with the `lumen-scope` class to retheme one area. Add the `lumen-inherit` class to follow your shadcn palette instead (`--chart-N`, `--destructive`).
- Dark mode follows the `.dark` class on an ancestor (the shadcn and next-themes convention).
- Update later by re-running the install with `--overwrite` (review the diff if you edited it). Changelog: https://beautiful-ui.dev/r/changelog.json

## Keyboard

| Keys | Action |
|---|---|
| Escape | Cancel |
| Tab | Move between actions |

## Motion inventory

| Interaction | What moves |
|---|---|
| Open | The dialog's rise and dim |
| Destructive action | Hold to confirm, as Lumen Button |

## Accessibility contract (preserve when editing)
- role=alertdialog; focus starts on the least destructive action
- The backdrop doesn't close it: the user must choose

## Install

```bash
npx shadcn@latest add @beautiful-ui-pro/lumen-alert-dialog
```

Pro item: needs the `@beautiful-ui-pro` registry in `components.json` and `BEAUTIFUL_UI_TOKEN` in `.env.local` (https://beautiful-ui.dev/account). Setup: https://beautiful-ui.dev/docs/pro. Your components.json `style` picks the build: radix-*, new-york and default get Radix, base-* gets Base UI.

## Credits
- Built on shadcn/ui (https://ui.shadcn.com)

The lumen foundation (the tokens listed above, keyframes and motion levels) installs once with the first component; its CSS is public at https://beautiful-ui.dev/r/lumen-foundation.json.
