# Install and place "avatar-001" (Initials Avatar) 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/avatar-001.json
Registry item: https://vibeui.ru/r/avatar-001.json
Installs to: components/vibeui/avatar-001.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
An avatar whose colour is derived from the name. A list of people with no photos stays readable, and the same person is always the same colour.
An avatar with initials and a presence dot. The background hue is derived from the name, so a list of forty photo-less people stays distinguishable and one person keeps their colour across pages and reloads. Three sizes, four presence states, an optional photo. Zero dependencies, one file, its own palette.
## 3. How to use it
import { Avatar001 } from "@/components/vibeui/avatar-001"
<Avatar001 name="Anna Kovalyova" status="online" />
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-avatar-001-* palette — do not swap it for your theme tokens (bg-muted, text-muted-foreground and the like)
- deriving the hue from the name: hueOf is deterministic, while a random colour would change on every render
- tying background and text to a single --vibeui-avatar-001-hue through oklch — that is what keeps contrast at any hue
- the visually hidden full name in [data-part="name"] and aria-hidden on the initials: a screen reader must read the name, not two letters
- the box-shadow ring around the presence dot: without it the dot disappears against a photo
- the sizes driven by the single --vibeui-avatar-001-size variable that the font and dot are calculated from
- the plain <img> instead of next/image: the component has to work in any React project
- the <style> block inside the component — it holds the palette and the geometry
## 6. You may change
- name — the person's name; the initials and the colour both come from it
- src — a photo URL; without it the initials show
- size: sm in lists and tables, md by default, lg on a profile
- status: online, away, busy, or none when presence is not shown
- outer spacing through className
## 7. Rules
- Do not replace hueOf with a random colour or Math.random: a person must always be the same colour.
- Do not derive the colour from an id or email when the UI shows a name: people connect the colour to what they see.
- An avatar stack is a separate component; this one is a single shape.
- 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/avatar-001.jsonhttps://vibeui.ru/r/avatar-001.jsonКомпонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-avatar-001-*. Оттенок считается из имени детерминированной функцией hueOf и подставляется в переменную --vibeui-avatar-001-hue: фон и цвет инициалов выводятся из неё через oklch, поэтому контраст держится на любом оттенке. Фото подставляется пропом src обычным <img>: компонент переносим и не зависит от next/image. Полное имя лежит скрытым текстом для скринридера, инициалы помечены aria-hidden.
Component source
The same file your agent installs. Here in case you would rather copy it by hand.

// Идея компонента: фон выводится из имени, а не задаётся руками. В списке из
