# Confirm Button (Notchset): prompt.md (v1.0.0)

- id: `confirm-button` · version 1.0.0 · component · pro (Pro)
- category: Actions
- build: Base UI (one set of files; its dependencies follow the build)
- install (this build): `npx shadcn@latest add @beautiful-ui-pro/confirm-button`
- npm dependencies: none
- registry dependencies: utils, https://beautiful-ui.dev/r/notchset-foundation.json
- docs: https://beautiful-ui.dev/components/confirm-button
- The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand.

Hold to delete: the key sinks onto its plate, a signal tint sweeps across it, the bin lid lifts and a 12-node meter lights a node per tenth. Release early and nothing happens; finish and it confirms, then offers Undo for five seconds.

## Build it
- Stack: React 19 (`ref` is a plain prop), TypeScript, Tailwind CSS v4 utilities, a shadcn-initialised project with the `@/*` alias.
- Packages: none beyond React.
- Files: `components/ui/notchset/confirm-button.tsx`; shared code: `lib/beautiful-ui/notchset/instrument.tsx`, `lib/beautiful-ui/notchset/root.ts`.
- Registry dependencies, installed with it automatically: shadcn `utils` (cn), `notchset-foundation`.
- Builds: one set of files for both, but its dependencies come in Base UI and Radix builds. 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: `ConfirmButton`, and every exported type.
- CSS: the install adds the notchset foundation (tokens, keyframes, motion levels) to your global stylesheet 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 `--notchset-*` custom properties (`--notchset-check`, `--notchset-control-edge`, `--notchset-draw-from`, `--notchset-ease-bloom`, `--notchset-ease-travel`, `--notchset-fade`, `--notchset-focus-color`, `--notchset-focus-inset`, `--notchset-life-from`, `--notchset-life-ms`, `--notchset-node-blink`, `--notchset-node-bloom`, `--notchset-node-delay`, `--notchset-plate-color`, `--notchset-rise-from`, `--notchset-rule`, `--notchset-scroll`, `--notchset-signal`, `--notchset-sweep-to`). Never add Tailwind colour classes inside the component.

```tsx
import { ConfirmButton } from "@/components/ui/notchset/confirm-button";
```

## Parts

| Part | data-slot | What it is for |
|---|---|---|
| `ConfirmButton` | `confirm-button` | The legend and meter, the key on its plate, and the help or Undo row. |
| `Key` | `confirm-button-key` | The button you hold. |
| `Undo` | `confirm-button-undo` | The Undo key and its draining nodes. |

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 `SoundProvider` once (install: `npx shadcn@latest add https://beautiful-ui.dev/r/notchset-sound.json`, import from `@/components/ui/notchset/sound-provider`); `useSound()` gives `muted` and `setMuted` for a mute control. Without a provider the audio engine never loads.

## Match the original
- Read `components/ui/notchset/confirm-button.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
- hold to delete, hold to confirm, destructive action, delete agent, confirm delete, undo, Notchset
- Deleting something that matters, without a confirmation dialog
- Destructive actions that should still be undoable for a moment

### Not when
- Everyday actions: holding is slow on purpose
- Actions you can't undo and must explain: use an Alert Dialog

## Mistakes
- Do the real deletion in onExpire (or keep it reversible until then)
- Keep it for destructive actions; it is signal on purpose

## Usage

```tsx
"use client";

import { ConfirmButton } from "@/components/ui/notchset/confirm-button";

/** Soft delete with an undo window; delete for good when it expires. */
export function DeleteAgent({ agentId, markDeleted, restore, deleteForever }: { agentId: string; markDeleted: (id: string) => void; restore: (id: string) => void; deleteForever: (id: string) => void }) {
  return (
    <ConfirmButton
      target="PLANNER-V13"
      labels={{ hold: "DELETE AGENT" }}
      onConfirm={() => markDeleted(agentId)}
      onUndo={() => restore(agentId)}
      onExpire={() => deleteForever(agentId)}
    />
  );
}
```

## Props

| Prop | Type | Default | What it does |
|---|---|---|---|
| `holdMs` | `number` |  | How long to hold (ms). Default 1200. |
| `undoMs` | `number` |  | How long Undo stays (ms). Default 5000; 0 for none. |
| `target` | `string` |  | What is deleted, for the help line and its announcement. |
| `onConfirm` | `() => void` |  | Called when the hold completes. |
| `onUndo` | `() => void` |  | Called when Undo is pressed. |
| `onExpire` | `() => void` |  | The undo window ran out: the deletion is final. |
| `labels` | `Partial<ConfirmButtonLabels>` |  | Every word, for other languages. |

## Customising
- Colours: the component reads your shadcn tokens (`--background`, `--foreground`, `--border` …), refined by the `--notchset-*` tokens. The signal colour is `--notchset-signal` (it falls back to `--destructive`). Set tokens on `:root`, or on any container to retheme one area.
- 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 |
|---|---|
| Space / Enter (hold) | Hold to delete |
| Esc | Cancel the hold |
| Tab | Reach Undo after confirming |

## Performance

- The hold runs one requestAnimationFrame loop only while held or draining, writing one CSS variable a frame.
- Idle keys do no JavaScript work.

## Responsive

- Fixed 40px key; the target label truncates rather than wrap.
- 44px on touch screens.

## Motion inventory

| Interaction | What moves |
|---|---|
| Hold | The key sinks 2px onto its plate (40ms); the tint sweeps linearly over the hold; the lid lifts and tilts to −18°; the meter lights one node per tenth with a bloom |
| Release early | The tint returns over 260ms; nothing happens |
| Confirm | The meter flashes three times; the label flips to DELETED; Undo's five nodes drain one per second |

## Accessibility contract (preserve when editing)
- The accessible name says what is deleted and how long to hold
- Space or Enter held down holds it; Esc or releasing cancels
- The result and the restore are announced politely
- Never fires before the full hold; any release cancels

## Install

```bash
npx shadcn@latest add @beautiful-ui-pro/confirm-button
```

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.

The notchset 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/notchset-foundation.json.
