- 1. Copy the link.
- 2. Write to your agent in your own words and drop the link into the sentence.
- 3. The agent opens the link and installs the component from the registry.
put this in the header: https://vibeui.ru/c/label-001?lang=en
We send the invoice and your account access there.

# Install and place "label-001" (Required Mark) 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/label-001.json
Registry item: https://vibeui.ru/r/label-001.json
Installs to: components/vibeui/label-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
A label for a required field: an asterisk with a screen-reader-only expansion and one line explaining why the field is there.
A required-field label with an asterisk, a hidden spoken expansion and an explanation underneath. Zero dependencies, one file, no client JS.
## 3. How to use it
import { Label001 } from "@/components/vibeui/label-001"
<Label001
label="Work email"
hint="We send the invoice and your account access there."
placeholder="name@company.com"
/>
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-label-001-* palette — do not swap it for your theme tokens
- the visually hidden text next to the asterisk: without it screen readers say "asterisk" instead of "required field"
- aria-hidden on the asterisk itself — otherwise the meaning is announced twice and gets in the way
- the aria-describedby link between the hint and the field: otherwise the line is visible but never spoken
- the native required attribute on the input — browser validation rests on it, with no script
- the block's own light surface: without it the dark label disappears on a dark background
## 6. You may change
- the field name through label and the explanation through hint
- the placeholder text through placeholder
- the focus and accent color through accent
- the block width through max-width in the palette
## 7. Rules
- An asterisk only works while required fields are the minority: if almost everything is required, mark the optional ones instead.
- The hint sits ABOVE the field on purpose: on a phone the keyboard covers the bottom of the screen and text under the field is invisible.
- The input type here is email; for another type change autoComplete as well, or autofill will paste the wrong value.
- 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/label-001.jsonhttps://vibeui.ru/r/label-001.jsonКомпонент самодостаточен: один файл, без зависимостей, палитра в локальных переменных --vibeui-label-001-*. Серверный: из хуков только useId, состояния нет. Звёздочка помечена aria-hidden, а её смысл несёт визуально скрытый текст «, обязательное поле» — иначе скринридер произносит «звёздочка» и оставляет гадать. Строка-объяснение связана с полем через aria-describedby, поэтому читается сразу после имени поля, а не теряется. Поле получает нативный required: валидация браузера остаётся рабочей. Блок несёт собственную светлую подложку с рамкой — тёмный текст подписи обязан читаться на тёмной карточке каталога.
Component source
The same file your agent installs. Here in case you would rather copy it by hand.
import { useId } from "react"
import type { ComponentPropsWithoutRef, CSSProperties } from "react"
export type Label001Props = Omit<
ComponentPropsWithoutRef<"div">,
"children"
> & {
label?: string
hint?: string
placeholder?: string
accent?: string
}
// Идея компонента: звёздочка сама по себе ничего не объясняет — половина
// людей читает её как «важное», а не «без этого форму не отправить».
// Поэтому здесь звёздочка нарисована, продублирована текстом для
// скринридера и подкреплена одной строкой, которая говорит зачем поле.
