  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.

# Install and place "sidebar-001" (App Sidebar Nav) 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/sidebar-001.json

Registry item: https://vibeui.ru/r/sidebar-001.json
Installs to: components/vibeui/sidebar-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 app sidebar: sections, counts and a current item marked by a bar at the edge rather than text colour alone.

A vertical app menu: titled sections, link items, counts on the right and a current item marked by an edge bar and a solid background. In a long list the current place is found at a glance. Zero dependencies, one file, its own palette, no client JS.

## 3. How to use it
import { Sidebar001 } from "@/components/vibeui/sidebar-001"

<Sidebar001
  activeLabel="Pages"
  sections={[
    { title: "Project", items: [{ label: "Overview", href: "/" }, { label: "Pages", href: "/pages", count: 12 }] },
  ]}
/>

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-sidebar-001-* palette — do not swap it for your theme tokens (bg-sidebar, bg-accent and the like)
- the double marking of the active item: the edge bar plus the background — text colour alone loses the active section
- aria-current="page" on the current item: it is how a screen reader finds it
- the <nav> + <ul> semantics: a menu is a list of links, not a pile of divs
- the section titles as labels rather than links — nobody navigates to them
- tabular-nums on the counts, otherwise the numbers jitter the right edge
- the <style> block inside the component — it holds the palette, the layout and the active marking

## 6. You may change
- the sections array: section titles, items, hrefs and counts
- activeLabel — the current item's label; in a real app feed it from the router
- the accent through the accent prop — it colours the bar and the focus ring
- max width and outer spacing through className

## 7. Rules
- The component knows nothing about routes. The caller decides the active item: compare the router path and pass the label.
- Do not nest deeper than one level: a tree needs a different component.
- A count means something needing attention — unread, failing. The total number of items does not belong there.
- 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/sidebar-001.json
https://vibeui.ru/r/sidebar-001.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-sidebar-001-*. Разметка семантическая: <nav> с подписью, внутри разделы с заголовками и списки <ul>. Активный пункт определяется сравнением подписи с activeLabel и получает aria-current="page", плотный фон и полосу через ::before. Счётчик — необязательное число справа с tabular-nums.

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 Sidebar001Item = {
  label: string
  href?: string
  /** Число справа: непрочитанные, черновики, ошибки. */
  count?: number
}

export type Sidebar001Section = {
  title?: string
  items: Sidebar001Item[]
}

export type Sidebar001Props = Omit<
  ComponentPropsWithoutRef<"nav">,
  "children"
> & {
  sections?: Sidebar001Section[]
  /** Подпись активного пункта. Сравнивается по тексту, а не по адресу. */
  activeLabel?: string
  accent?: string
}

// Идея компонента: активный пункт отмечен полосой у левого края и плотным
// фоном, а не только цветом текста. В длинном списке разделов взгляд находит
// текущее место сразу, и метка не исчезает при смене темы.
