  1. 1. Copy the link.
  2. 2. Write to your agent in your own words and drop the link into the sentence.
  3. 3. The agent opens the link and installs the component from the registry.

# Install and place "autocomplete-011" (Mention Picker) from VibeUI

## 1. Install first — do not skip, do not recreate
Run this exact command before writing any code:
npx shadcn@latest add https://vibeui.ru/r/autocomplete-011.json

Registry item: https://vibeui.ru/r/autocomplete-011.json
Installs to: components/vibeui/autocomplete-011.tsx (the exact path follows this project's components.json aliases).
npm dependencies: none.
Registry dependencies: none.

Install it from the registry. Do not recreate it from the description,
do not substitute a similar component from another library, and do not
rewrite it to match the project's existing style.

## 2. What it is
Mentions inside the text itself: the list opens on an @ before a word, not on focus in the field.

A comment field with mentions: the list appears after an @ before a word, each row shows name, role and handle, and picking one inserts the mention into the text. Zero dependencies, one file, its own palette.

## 3. How to use it
import { Autocomplete011 } from "@/components/vibeui/autocomplete-011"

<Autocomplete011
  people={[{ name: "Anna Petrova", handle: "anna", role: "design" }]}
  onChange={(text) => console.log(text)}
/>

Read the installed file for the full prop list.

## 4. Where to place it
This is a small inline component. Put it exactly where the user asked,
inside the existing markup. Do not create a new page, section or
wrapper for it. If a similar control already sits in that spot,
replace it instead of adding a second one.

Placement: ___
(The user fills this line in. If it is still blank, ask where to put it
instead of guessing.)

## 5. Keep exactly as installed
- the local --vibeui-autocomplete-011-* palette — do not swap it for your theme tokens
- opening on the @ rather than on focus: a mention lives mid-sentence
- ending the token at a space — otherwise the list hangs around to the end of the paragraph
- tracking the caret on click and arrow keys, not only while typing
- inserting a trailing space after the handle: the next word would stick to the mention
- initials instead of photos: forty avatars are not loaded for a dropdown

## 6. You may change
- the people array: name, handle and role
- the label, placeholder and starting text
- the onChange handler
- the accent through the accent prop

## 7. Rules
- The list is not anchored to the caret: it sits under the field. Popping up at the caret needs measurement, which is a different component.
- A mention is plain text: parsing @handles and sending notifications is your backend's job.
- The avatar hue is derived from the name and stable, but not unique: two people can land on close colours.
- Do not lift the CSS variables into globals.css: the component has to stay a single file.

## 8. Verify
- it renders with no console errors;
- it looks like the preview on the VibeUI page you copied this from;
- if it does not, you changed something listed in section 5 — put it back.

For developers

npx shadcn@latest add https://vibeui.ru/r/autocomplete-011.json
https://vibeui.ru/r/autocomplete-011.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-autocomplete-011-*. Клиентский: "use client". Токен упоминания вычисляется от последней собаки до курсора и обрывается на пробеле, поэтому список гаснет сам. Позиция курсора отслеживается на onChange, onKeyUp и onClick. Аватар — инициалы на оттенке, посчитанном из имени: сумма кодов символов по модулю 360 отдаётся в локальную переменную оттенка.

Component source

The same file your agent installs. Here in case you would rather copy it by hand.

"use client"

import { useId, useMemo, useState } from "react"
import type {
  ChangeEvent,
  ComponentPropsWithoutRef,
  CSSProperties,
} from "react"

export type Autocomplete011Person = {
  name: string
  handle: string
  role: string
}

export type Autocomplete011Props = Omit<
  ComponentPropsWithoutRef<"div">,
  "children" | "onChange" | "defaultValue"
> & {
  label?: string
  placeholder?: string
  people?: Autocomplete011Person[]
  defaultValue?: string
  onChange?: (value: string) => void
  accent?: string
}

// Идея компонента: подсказка внутри текста. Список появляется не от фокуса, а
// от собаки перед словом — упоминание живёт посреди фразы, и открывать его
// каждый раз при клике в поле значит мешать письму. Аватар — инициалы на
// оттенке из имени: сорок фотографий ради выпадающего списка не грузим.
