# Sprint Board (Notchset): prompt.md (v1.0.0)

- id: `sprint-board` · version 1.0.0 · block · pro (Pro)
- category: Application UI
- build: Base UI (one set of files; its dependencies follow the build)
- install (this build): `npx shadcn@latest add @beautiful-ui-pro/sprint-board`
- npm dependencies: class-variance-authority@^0.7
- registry dependencies: utils, @beautiful-ui/segmented-control, https://beautiful-ui.dev/r/notchset-foundation.json
- docs: https://beautiful-ui.dev/components/sprint-board
- The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand.

A sprint board: progress as a ruler of done tasks, four columns with rolling counts, a work-in-progress limit that refuses a card with a shake, cards that open to their description and move with arrows, entering from the side they came from, a strikethrough drawn across done titles, ALL / MY WORK and an inline add-task field.

## Build it
- Stack: React 19 (`ref` is a plain prop), TypeScript, Tailwind CSS v4 utilities, a shadcn-initialised project with the `@/*` alias.
- Packages: `class-variance-authority@^0.7`.
- Files: `components/ui/notchset/blocks/sprint-board.tsx`; shared code: `lib/beautiful-ui/notchset/instrument.tsx`, `lib/beautiful-ui/notchset/root.ts`, `lib/beautiful-ui/notchset/button-variants.ts`, `lib/beautiful-ui/notchset/field-classes.ts`.
- Registry dependencies, installed with it automatically: shadcn `utils` (cn), `segmented-control`, `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: `SprintBoard`, 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-glide`, `--notchset-ease-key-down`, `--notchset-ease-key-up`, `--notchset-ease-travel`, `--notchset-fade`, `--notchset-focus-color`, `--notchset-focus-inset`, `--notchset-grow-to`, `--notchset-key-down`, `--notchset-key-up`, `--notchset-life-from`, `--notchset-life-ms`, `--notchset-node-blink`, `--notchset-node-bloom`, `--notchset-node-delay`, `--notchset-plate-color`, `--notchset-rise-from`, `--notchset-rule`, `--notchset-scan-to`, `--notchset-scroll`, `--notchset-signal`, `--notchset-sweep-to`, `--notchset-travel`). Never add Tailwind colour classes inside the component.

```tsx
import { SprintBoard, type SprintTask } from "@/components/ui/notchset/blocks/sprint-board";
```

## Parts

| Part | data-slot | What it is for |
|---|---|---|
| `SprintBoard` | `sprint-board` | Header, progress, the four columns and the status line. |

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/blocks/sprint-board.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
- kanban, sprint board, task board, scrum board, wip limit, project board, todo board, Notchset
- A team's sprint or project board
- Boards where a work-in-progress limit should be enforced

### Not when
- Hundreds of cards: use a table with filters
- Free-form drag and drop across many lanes: use a dedicated board library

## Mistakes
- Enforce the WIP limit on the server too
- Keep areas short; they truncate before the due date does

## Usage

```tsx
import { SprintBoard, type SprintTask } from "@/components/ui/notchset/blocks/sprint-board";

export function Board({ tasks }: { tasks: SprintTask[] }) {
  return (
    <SprintBoard
      label="SPRINT 41"
      title="Ship v15"
      tasks={tasks}
      people={{ MK: { name: "Maya Kerr", me: true } }}
      onMove={(task, to) => fetch(`/api/tasks/${task.id}`, { method: "PATCH", body: JSON.stringify({ column: to }) })}
    />
  );
}
```

## Props

| Prop | Type | Default | What it does |
|---|---|---|---|
| `tasks` | `{ id, area, title, due, assignee, comments, column, description }[]` |  | column is "planned", "progress", "review" or "done"; due "TODAY" shows in signal. |
| `people` | `Record<initials, { name, me? }>` |  | The team; `me` adds ALL / MY WORK. |
| `label / title / daysLeft` | `string` |  | The header and the time left. |
| `wipLimit` | `number` |  | Cards allowed in IN PROGRESS (default 3). |
| `onMove / onAdd` | `(task, to) => void / (title) => Promise<task>` |  | Persist moves; create tasks on your server (defaults to a local task). |

## 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 |
|---|---|
| Tab then Enter | Open a card, move it back or forward |
| Enter / Esc | Add or cancel in the add-task field |
| ← → | ALL / MY WORK |

## Performance

- Plain cards and CSS transitions; nothing runs while idle.

## Responsive

- Under 760px (container width) the columns scroll sideways with snap, one and a bit in view.

## Motion inventory

| Interaction | What moves |
|---|---|
| Move | A card enters its new column from the side it came from (460ms settle) |
| Done | A strikethrough draws across each line of the title (420ms) |
| WIP limit | The full column shakes and outlines in signal |
| Progress | Ruler cells fill 40ms apart |

## Accessibility contract (preserve when editing)
- Columns are labelled groups with their counts; the WIP limit is an image labelled with how full it is
- Card titles are buttons with aria-expanded; move buttons are named with the task and aria-disabled at the ends
- Every move, refusal and addition is announced in the status line

## Install

```bash
npx shadcn@latest add @beautiful-ui-pro/sprint-board
```

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.

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

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.
