  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/codeblock-007?lang=en

hooks/use-total.tsстрока 4
const cart = useCart() const total = cart.items.reduce((sum, item) => {  return sum + item.prise * item.count}, 0)

Typo: the item field is price, not prise

# Install and place "codeblock-007" (Error Range) 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/codeblock-007.json

Registry item: https://vibeui.ru/r/codeblock-007.json
Installs to: components/vibeui/codeblock-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 code block with a highlighted range of lines: a bar on the left, a wavy underline and a callout that says plainly what is wrong.

A listing with a highlighted line range and an error note underneath: a bar, a tint and a wavy underline plus a callout. Zero dependencies, no client JS.

## 3. How to use it
import { Codeblock007 } from "@/components/vibeui/codeblock-007"

<Codeblock007
  path="hooks/use-total.ts"
  errorFrom={4}
  errorTo={4}
  message="Typo: the item has price"
/>

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-codeblock-007-* palette — do not swap it for your theme tokens
- all three error cues at once: bar, tint and underline — colour alone reads poorly
- the callout text: highlighting without an explanation leaves the reader guessing
- the line number in ::before so it does not travel to the clipboard with the code
- the range chip in the header: in a long listing it says where to scroll
- the dark block surface — red on a light background reads as a link, not an error

## 6. You may change
- the listing rows through the lines array
- the range bounds through errorFrom and errorTo
- the callout text through message and the file through path
- the error hue to match your palette

## 7. Rules
- The whole range is highlighted: this block does not point at a column inside a line.
- text-decoration-skip-ink is disabled on purpose — otherwise the wave breaks under descenders.
- A range outside the list of rows simply highlights nothing: bounds are the caller's job.
- 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/codeblock-007.json
https://vibeui.ru/r/codeblock-007.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-codeblock-007-*. Серверный: хуков нет. Диапазон задаётся числами errorFrom и errorTo, номер строки печатается ::before через content:attr(data-line), а сама ошибка отмечена тремя независимыми признаками: полосой слева, подложкой и text-decoration:underline wavy. Под листингом стоит абзац с role=note и стрелкой вверх в псевдоэлементе — он связывает подсветку с текстом объяснения.

Component source

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

import type { ComponentPropsWithoutRef, CSSProperties } from "react"

export type Codeblock007Props = Omit<
  ComponentPropsWithoutRef<"figure">,
  "children"
> & {
  path?: string
  message?: string
  errorFrom?: number
  errorTo?: number
  lines?: string[]
}

// Идея компонента: не просто подсветить строку, а сказать, что с ней не так.
// Диапазон помечен полосой слева и волнистым подчёркиванием, а под ним стоит
// выноска с текстом ошибки — читатель не ищет, куда смотреть.
