# CitationChip

Inline per-claim source marker [n] that pairs with a sources list — the grounded-agent citation UX.

[All components](https://rickylabs.github.io/netscript/design-system/components/) · [Theme builder](https://rickylabs.github.io/netscript/create/) · [Implementation source](https://github.com/rickylabs/netscript/blob/main/packages/fresh-ui/registry/components/ui/citation-chip.tsx)

## Live preview

[Open live citation-chip preview](https://rickylabs.github.io/netscript/assets/fresh-ui/preview/?component=citation-chip&theme=studio-utility)

## Install

```bash
netscript ui:add citation-chip
```

## Usage and examples

The preview runs this JSX with the installed components. Import any composed primitives from your UI directory.

```tsx
import { useState } from 'preact/hooks';
import { CitationChip } from '@app/components/ui/citation-chip.tsx';

export function Example() {
  const [value, setValue] = useState('standard');
  const [open, setOpen] = useState(false);
  const [notice, report] = useState('');
  return (<><div><CitationChip index={1} source="Order policy" onClick={()=>report("Order policy selected")} /></div><p role="status">{notice}</p></>);
}
```

## Props

Generated from native `deno doc --json --private` over the shipped implementation. Compound component props retain their owning interface; native attributes pass through where declared.

| Owner | Prop | Type | Optional | Description |
| --- | --- | --- | --- | --- |
| `CitationChipProps` | `index` | `number` | No | 1-based citation number rendered in the chip. |
| `CitationChipProps` | `source` | `string` | Yes | Source label, surfaced as the hover title + accessible name. |
| `CitationChipProps` | `active` | `boolean` | Yes | Active when its matching source row is selected. |
| `CitationChipProps` | `onClick` | `(index: number) => void` | Yes | Invoked with the citation index on activation. |
| `CitationChipProps` | `class` | `string` | Yes |  |

```typescript
CitationChipProps extends Omit<JSX.HTMLAttributes<HTMLButtonElement>, "class" | "onClick">
```

## Keyboard

| Key | Action |
| --- | --- |

## Contract and compatibility

Accessibility pattern: native link

- Native DOM attributes pass through where the implementation accepts them.

Design contract values marked planned are not implementation props. The props above describe what ships today.
