  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.

put this in the header: https://vibeui.ru/c/label-007?lang=en

No such address: check that a domain follows the @.

# Install and place "label-007" (Error Label) 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-007.json

Registry item: https://vibeui.ru/r/label-007.json
Installs to: components/vibeui/label-007.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 with the error message between it and the field: the entire error styling hangs on a single aria-invalid attribute.

A label with an error message: the state is driven by one aria-invalid, and the text is tied to the field and backed by an icon. Zero dependencies, one file, no client JS.

## 3. How to use it
import { Label007 } from "@/components/vibeui/label-007"

<Label007
  label="Billing email"
  error="No such address: check the domain after the @."
  defaultValue="accounting@company"
/>

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-007-* palette — do not swap it for your theme tokens
- aria-invalid as the single source of state: a parallel CSS class will drift out of sync sooner or later
- the aria-describedby link between message and field — otherwise the error is seen but never heard
- the icon next to the text: color alone fails color-blind readers and greyscale printing
- the message above the field — on a phone the keyboard covers everything below the input
- 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, the message through error and the typed value through defaultValue
- the normal focus color through accent
- the error colors through the --vibeui-label-007-error and --vibeui-label-007-error-soft variables
- the input type and autofill hint for your own case

## 7. Rules
- The error is rendered up front: if it appears after submission, add role="alert" to the message or the screen reader stays silent.
- The message has to say what to fix rather than "invalid value", or people get stuck.
- When you drop aria-invalid, drop aria-describedby too, or the field keeps pointing at nothing.
- 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-007.json
https://vibeui.ru/r/label-007.json

Компонент самодостаточен: один файл, без зависимостей, палитра в локальных переменных --vibeui-label-007-*. Серверный: из хуков только useId. Единственный источник состояния — aria-invalid у поля: подпись краснеет правилом :has(input[aria-invalid="true"]), рамка и обводка фокуса — селектором по тому же атрибуту. Отдельного класса «error» нет, поэтому состояния не разъезжаются. Сообщение стоит между подписью и полем: на телефоне клавиатура закрывает низ экрана, и текст под полем не виден. К цвету добавлен нарисованный рамкой значок — цвет не должен быть единственным признаком ошибки. Сообщение связано с полем через aria-describedby.

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 Label007Props = Omit<
  ComponentPropsWithoutRef<"div">,
  "children" | "defaultValue"
> & {
  label?: string
  error?: string
  defaultValue?: string
  accent?: string
}

// Идея компонента: сообщение об ошибке стоит между подписью и полем — так
// его видно до того, как палец на телефоне закроет низ поля клавиатурой.
// Вся раскраска висит на одном атрибуте aria-invalid у поля: включил
// атрибут — покраснела рамка, подпись и текст, отдельного класса нет.
