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.

# Install and place "codeblock-022" (Masked Env) 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-022.json

Registry item: https://vibeui.ru/r/codeblock-022.json
Installs to: components/vibeui/codeblock-022.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 list of environment variables with hidden values: a row opens by its own toggle or by the master one in the header, and all of it without client JS.

Environment variables with masked values: reveal them row by row or all at once, state on checkboxes and :has(). Zero dependencies, no client JS.

## 3. How to use it
import { Codeblock022 } from "@/components/vibeui/codeblock-022"

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-022-* palette — do not swap it for your theme tokens
- deriving the scope badge from the key name: a hand-set badge eventually lies
- the two independent sources of reveal: the master toggle and the per-row toggle
- hiding the checkboxes with clip-path rather than display:none — otherwise they leave the tab order
- the footer note about the masking being visual: without it the block looks like protection it is not
- the dark surface of the block — light monospaced text is unreadable without it

## 6. You may change
- the list of variables through variables
- the file name through file
- showing every value at once through revealAll
- the colours of the scope badge and the mask

## 7. Rules
- The masking is visual: the values sit in the page markup, so real secrets never go here.
- The master toggle overrides the per-row ones: uncheck it to get the row behaviour back.
- A long value is truncated with an ellipsis — in full it is only visible in the page source.
- 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-022.json

https://vibeui.ru/r/codeblock-022.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-codeblock-022-*. Серверный: состояние держат нативные чекбоксы, а показ значения включают два независимых селектора :has() — на строке и на всём блоке от общего переключателя в шапке. Область видимости переменной выводится из её имени: ключи с префиксом NEXT_PUBLIC_ получают другой значок, поэтому подпись не может разойтись с реальностью. Чекбоксы спрятаны clip-path, у каждого есть визуально скрытая подпись с именем ключа для читалки экрана.

Component source

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

import type { CSSProperties } from "react"

export type Codeblock022Variable = {
  key: string
  value: string
}

export type Codeblock022Props = {
  file?: string
  revealAll?: boolean
  variables?: Codeblock022Variable[]
  className?: string
  style?: CSSProperties
}

// Идея компонента: показать состав .env, не показывая сами значения. Каждая
// строка закрыта точками и открывается своим чекбоксом, а общий переключатель
// в шапке открывает все сразу — всё на :has(), без клиентского состояния.
