About

The simplest honest chat surface: it renders what it is given and has no opinion about the model. Compose it with the Prompt Composer.

Use it when

An assistant or support chat needs a thread.

Skip it when

You need streaming markdown: render that inside each message.

Install

1Add the VibeBox registry to components.json:

{
  "registries": {
    "@vibebox": "https://motion.vibeboxph.com/r/{name}.json"
  }
}

2Add the component with the shadcn CLI:
npx shadcn@latest add @vibebox/chat-thread

3Use it:

import { ChatThread } from "@/components/vibebox/chat-thread";

<ChatThread accent="#7c5cff" />

AI prompt

Everything an AI coding tool needs to rebuild this component the way it looks here: colours, fonts, the art it draws, props and rules.

Read the prompt

Build the VibeBox Motion component "Chat Thread" (AI and agents) in a Next.js App Router project with Tailwind CSS v4.

What it is
- A chat conversation: your messages in the accent, replies on a card, and a typing indicator.
- The thread of an assistant or a support chat: user messages in the accent colour on the right, replies on a card on the left, and an optional typing indicator that bobs. It is a live region log, so new messages are announced, and every colour comes from the accent and the tokens.

Install
- `npx shadcn@latest add @vibebox/chat-thread`
- Registry: add `"@vibebox": "https://motion.vibeboxph.com/r/{name}.json"` to components.json, then run the command. The source lands in `components/vibebox/chat-thread` and is yours to edit.

Visual spec
- Colours (the VibeBox spectrum, the same in light and dark):
    - --spectrum-1: #00c5fc (cyan)
    - --spectrum-2: #1d6ef0 (blue)
    - --spectrum-3: #5225ed (indigo)
    - --spectrum-4: #e434dc (magenta)
    - --spectrum-5: #fd3aa9 (pink)
    - --spectrum-6: #f98472 (coral)
    - --spectrum-7: #fcbe72 (amber)
- Ink surface (dark): background #05070c, card #0a0d15, text #f5f6fa, muted text #a3abbd, border rgba(255,255,255,0.08).
- Paper surface (light): background #f3f0ea, card #fbfaf7, text #0c0e14, muted text #4a4f5c, border rgba(12,14,20,0.12).
- Fonts:
    - Display and body: Figtree (400, 500, 600, 700), falling back to ui-sans-serif, system-ui.
    - Emphasis: Fraunces italic, for one or two words of a heading.
    - Labels and code: JetBrains Mono (400, 500), uppercase labels with 0.14em tracking.
- Shape: radius 8 to 12px on cards and panels; pills may be fully round. Hairline borders, soft glow instead of heavy shadow.
- Motion: animate transform and opacity only; fast ease-out (cubic-bezier(0.16, 1, 0.3, 1)), 140ms for micro-interactions, 320 to 520ms for reveals.

Art and media
- Built from HTML, CSS and inline SVG only; no image files or video.

Props
- `messages`: `{ role: "user" | "assistant"; text: string }[]`. The conversation, oldest first.
- `typing`: `boolean` (default true). Show the typing indicator after the last message.
- `accent`: `string` (default "blue"). The accent colour: blue, violet, emerald, amber, rose, or any CSS colour. It sets --app-accent on the root, so a parent can set it once for a whole screen.
- `className`: `string`. Merged with cn(); give it a width.

Behaviour and access
- Reduced motion: Nothing animates on its own.
- Keyboard: Every control is a native element in reading order.
- Screen readers: Semantic elements with accessible names; decorative marks are hidden.
- Touch: Targets are 36 px or larger; nothing depends on hover.
- Budget: about 0 KB of JavaScript, WebGL none, GPU none. It pauses while off screen.

Theming
Everything reads `--app-accent` (set by the `accent` prop, or by a parent) and the mode's tokens, so light and dark and any brand colour work without code changes. Pass a named accent or any CSS colour; Launchpad sets it once per app from the client's theme.

Usage
```tsx
import { ChatThread } from "@/components/vibebox/chat-thread";

<ChatThread accent="#7c5cff" />
```

Notes
Add the VibeBox Motion Chat Thread with `npx shadcn@latest add @vibebox/chat-thread`. Use it for the conversation area of an assistant; pass messages from your state. Set the brand colour once with `--app-accent` on a parent (or the `accent` prop). It follows light and dark through the tokens; keep the licence header.

Rules
- Keep the licence header on every installed file.
- Original code only: do not copy components from other libraries, and do not add GSAP.
- Use tokens for colour, type and radius; no hard-coded brand values.
- Server Components by default; `"use client"` only for the island.
