# Task card (Notchset): prompt.md (v2.1.0)

- id: `task-card` · version 2.1.0 · block · pro (Pro)
- category: Application UI
- build: one set of files for every shadcn style
- install: `npx shadcn@latest add @notchset-pro/task-card`
- npm dependencies: none
- registry dependencies: utils, https://notchset.dev/r/notchset-foundation.json
- docs: https://notchset.dev/blocks/task-card
- The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand.

A task on a board answering three things at a glance: what it is (the title and labels), whether something is wrong (one flag line in words) and who and when (its key, priority, marks, due date and assignee). A lens dims the cards that don't match. It carries the board's card id, so the Board drags and moves it..

## Build it
- Stack: React 18.3 or 19, TypeScript, Tailwind CSS v4 utility classes on the foundation's roles, a components.json (imports use its aliases).
- Packages: none beyond React.
- Files: `components/ui/notchset/blocks/task-card.tsx`.
- Registry dependencies, installed with it automatically: shadcn `utils` (cn), `notchset-foundation`.
- Builds: one set of files, the same for every shadcn style.
- Exports to keep: `TaskCard`, and every exported type.
- CSS: the install adds the notchset foundation (its roles, keyframes and motion switch, reading your shadcn tokens for colour) 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.
- Colours: every part reads the foundation's roles (`--ns-canvas`, `--ns-ink`, `--ns-line`, `--ns-signal` …), which read your shadcn tokens (`--background`, `--foreground`, `--border`, `--destructive` …), plus the optional `--success` and `--warning`. Retheme on `:root` or any container; never add Tailwind colour classes inside the component.
- This item reads `--ns-bad-ink`, `--ns-bezel`, `--ns-font-mono`, `--ns-ink`, `--ns-ink-2`, `--ns-ink-3`, `--ns-line`, `--ns-line-soft`, `--ns-radius-sm`, `--ns-raised`, `--ns-text-body`, `--ns-text-meta`, `--ns-time-color`, `--ns-warn`, `--ns-weight-medium`.
- Retune it (on any ancestor) with the foundation's roles and hooks: `--ns-bad`, `--ns-bad-ink`, `--ns-band`, `--ns-band-edge`, `--ns-band-grade`, `--ns-band-optimal`, `--ns-beat`, `--ns-bezel`, `--ns-canvas`, `--ns-cat-1`, `--ns-cat-2`, `--ns-cat-3`, `--ns-cat-4`, `--ns-cat-5`, `--ns-cat-6`, `--ns-check`, `--ns-chip`, `--ns-control`, `--ns-control-pad`, `--ns-control-sm`, `--ns-deep`, `--ns-deep-ink`, `--ns-deep-ink-2`, `--ns-deep-line`, `--ns-dialog`, `--ns-dialog-lg`, `--ns-dialog-sm`, `--ns-ease`, `--ns-ease-in`, `--ns-ease-panel`, `--ns-ease-pop`, `--ns-field`, `--ns-flood-arc`, `--ns-flood-aurora`, `--ns-flood-behind-1`, `--ns-flood-behind-2`, `--ns-flood-bloom`, `--ns-flood-deep`, `--ns-flood-dial-bloom`, `--ns-flood-glass`, `--ns-flood-grain`, `--ns-flood-image`, `--ns-flood-ink`, `--ns-flood-ink-low`, `--ns-flood-light`, `--ns-flood-mid`, `--ns-flood-pale`, `--ns-flood-pane`, `--ns-flood-pane-edge`, `--ns-flood-pill-ink`, `--ns-flood-ribbon`, `--ns-flood-ribbon-core`, `--ns-flood-shadow`, `--ns-flood-sheen`, `--ns-flood-wash`, `--ns-font-body`, `--ns-font-display`, `--ns-font-mono`, `--ns-font-script`, `--ns-glass`, `--ns-glass-blur`, `--ns-glass-shadow`, `--ns-glow`, `--ns-grain`, `--ns-gutter`, `--ns-header`, `--ns-heat`, `--ns-hover`, `--ns-ink`, `--ns-ink-2`, `--ns-ink-3`, `--ns-ink-4`, `--ns-leading`, `--ns-lift`, `--ns-light-1`, `--ns-light-2`, `--ns-light-3`, `--ns-light-spread`, `--ns-light-strength`, `--ns-line`, `--ns-line-soft`, `--ns-lit-edge`, `--ns-menu-dy`, `--ns-menu-row`, `--ns-mesh`, `--ns-mesh-frost`, `--ns-ok`, `--ns-ok-ink`, `--ns-orb-body`, `--ns-orb-cool`, `--ns-orb-core`, `--ns-orb-dawn`, `--ns-orb-deep`, `--ns-orb-edge`, `--ns-orb-grain`, `--ns-orb-ground`, `--ns-orb-halo`, `--ns-orb-inner`, `--ns-orb-key`, `--ns-orb-lift`, `--ns-orb-limb`, `--ns-orb-limb-from`, `--ns-orb-rim`, `--ns-orb-skin-hi`, `--ns-orb-skin-lo`, `--ns-orb-skin-mid`, `--ns-orb-warm`, `--ns-panel`, `--ns-panel-w`, `--ns-prism-edge`, `--ns-prism-glint`, `--ns-prism-sheen`, `--ns-prism-tint`, `--ns-pulse`, `--ns-radius`, `--ns-radius-card`, `--ns-radius-full`, `--ns-radius-lg`, `--ns-radius-sm`, `--ns-radius-xl`, `--ns-raised`, `--ns-range`, `--ns-row`, `--ns-row-compact`, `--ns-segment`, `--ns-selected`, `--ns-series`, `--ns-series-core`, `--ns-series-lilac`, `--ns-series-tint`, `--ns-shadow-dialog`, `--ns-shadow-float`, `--ns-shadow-panel`, `--ns-sheet`, `--ns-sheet-bottom`, `--ns-side`, `--ns-signal`, `--ns-sleep-awake`, `--ns-sleep-deep`, `--ns-sleep-light`, `--ns-sleep-rem`, `--ns-space-1`, `--ns-space-2`, `--ns-space-3`, `--ns-space-4`, `--ns-space-5`, `--ns-space-6`, `--ns-space-8`, `--ns-space-section`, `--ns-stack-on`, `--ns-standing-critical`, `--ns-standing-in`, `--ns-standing-out`, `--ns-state-doing`, `--ns-state-done`, `--ns-state-review`, `--ns-state-todo`, `--ns-switch-h`, `--ns-switch-w`, `--ns-text-body`, `--ns-text-control`, `--ns-text-display`, `--ns-text-figure`, `--ns-text-headline`, `--ns-text-hero`, `--ns-text-lede`, `--ns-text-meta`, `--ns-text-page`, `--ns-text-record`, `--ns-text-small`, `--ns-text-strong`, `--ns-text-sub`, `--ns-text-title`, `--ns-tile-shadow`, `--ns-time-born`, `--ns-time-color`, `--ns-time-dialog`, `--ns-time-menu`, `--ns-time-page`, `--ns-time-panel`, `--ns-time-toast`, `--ns-tint`, `--ns-tint-ink`, `--ns-toast-bottom`, `--ns-toast-left`, `--ns-touch`, `--ns-tracking-display`, `--ns-tracking-headline`, `--ns-warn`, `--ns-warn-ink`, `--ns-wash-clay`, `--ns-wash-dusk`, `--ns-wash-graphite`, `--ns-wash-ink`, `--ns-wash-sage`, `--ns-wash-sand`, `--ns-weight-light`, `--ns-weight-medium`, `--ns-weight-regular`, `--ns-weight-strong`, `--ns-well`.
- Never add Tailwind colour classes inside the component.

```tsx
import { Avatar } from "@/components/ui/notchset/avatar";
```

## Parts
- A single export that takes props.

## Match the original
- Read `components/ui/notchset/blocks/task-card.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

### Not when

## Mistakes
- Recreating the component instead of installing it

## Usage

```tsx
import { Hourglass, MessageSquare, OctagonAlert } from "lucide-react";
import { Avatar } from "@/components/ui/notchset/avatar";
import { PriorityMark } from "@/components/ui/notchset/priority-mark";
import { TaskCard } from "@/components/ui/notchset/blocks/task-card";

export default function TaskCardDemo() {
  return (
    <div className="grid w-full max-w-[560px] grid-cols-2 gap-2 max-[600px]:grid-cols-1">
      <TaskCard
        id="RP-55"
        code="RP-55"
        title="Route conflicts when two technicians share a van"
        labels={["Backend"]}
        flag={{ icon: <Hourglass />, text: "Stuck · 9 days in progress" }}
        priority={<PriorityMark priority={2} />}
        meta={<span className="inline-flex items-center gap-1"><MessageSquare aria-hidden />2</span>}
        due="Today"
        avatar={<Avatar name="Leo Brandt" size={20} />}
      />
      <TaskCard id="RP-63" code="RP-63" title="Keyboard shortcuts for the planner" labels={["Frontend"]} flag={{ icon: <OctagonAlert />, text: "Waits on RP-57" }} priority={<PriorityMark priority={2} />} due="Oct 29" avatar={<Avatar name="Maya Lindqvist" size={20} />} />
      <TaskCard id="RP-59" code="RP-59" title="Write the v1 to v2 migration plan" priority={<PriorityMark priority={4} />} due="3 days late" late avatar={<Avatar name="Maya Lindqvist" size={20} />} />
      <TaskCard id="RP-48" code="RP-48" title="Planner shell and day picker" done dim due="today" avatar={<Avatar name="Ines Halvorsen" size={20} />} />
    </div>
  );
}
```

This example also uses `avatar` (https://notchset.dev/components/avatar), `priority-mark` (https://notchset.dev/components/priority-mark), the npm package `lucide-react`. Installing this item doesn't bring them; to paste the example as it is: `npx shadcn@latest add @notchset-pro/task-card @notchset/avatar @notchset/priority-mark`. The `@notchset-pro` items are Pro: they need the registries in components.json and the key (Setup).

## Props

| Prop | Type | Default | What it does |
|---|---|---|---|
| `id` | `string` |  | Required. |
| `title` | `string` |  | Required. |
| `labels` | `(string \| { label: string; color?: string \| undefined })[]` | `[]` | its labels, each a name or a name with its identity colour (a dot beside the name, which stays ink) |
| `flag` | `{ icon?: React.ReactNode; text: string; tone?: "warn" \| "bad" \| undefined }` |  | the one thing wrong with it, in words |
| `code` | `string` |  |  |
| `priority` | `React.ReactNode` |  |  |
| `meta` | `React.ReactNode` |  | small marks: comments, subtasks |
| `due` | `string` |  |  |
| `late` | `boolean` |  |  |
| `avatar` | `React.ReactNode` |  |  |
| `done` | `boolean` |  |  |
| `dim` | `boolean` |  |  |
| `active` | `boolean` |  | the card the keyboard or the open drawer is on: ringed in ink |
| `description` | `string` |  | what a screen reader hears for the card beyond its title ("In progress, due today, Leo") |

## Customising
- Colours: every part reads the foundation's roles (`--ns-canvas`, `--ns-ink`, `--ns-line`, `--ns-signal` …), which read your shadcn tokens (`--background`, `--foreground`, `--border`, `--destructive` …), plus the optional `--success` and `--warning`. Retheme on `:root` or any container; never add Tailwind colour classes inside the component.
- Dark mode follows the `.dark` class or `data-theme="dark"` on an ancestor (the shadcn and next-themes conventions).
- Update later: Commit or stash local changes first (or copy the files), so the update can be undone. Read https://notchset.dev/r/changelog.json for the new versions: a major version, an entry marked breaking or a merge says what to change. Then re-run the install with `--overwrite`, on a branch. It replaces the component's files, the shared helper files they import, and the item's CSS rules in the global stylesheet, so review the whole diff (components, shared files, CSS), re-apply your own edits, and run the app's typecheck, tests and build.

## Accessibility contract (preserve when editing)

## Install

```bash
npx shadcn@latest add @notchset-pro/task-card
```

Pro item: needs the `@notchset-pro` registry in `components.json` and `NOTCHSET_TOKEN` in `.env.local` (https://notchset.dev/account). Setup: https://notchset.dev/docs/pro. Every components.json `style` gets the same files.

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