Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

shadcnui scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 23d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

shadcn/ui

shadcn/ui is not a component library; it's a collection of reusable components that you copy and paste into your apps. Built on Radix UI and Tailwind.

When to Use

  • Modern Copy-Paste Component Architecture: Full ownership of React UI components without npm dependency lock-in.
  • Accessible Design Systems with Tailwind CSS & Radix UI: Fully accessible WAI-ARIA primitives styled with Tailwind.
  • Next.js & Vite Modern Web Applications: Building polished SaaS dashboards and web interfaces.
  • Themable Component Libraries: Customizing CSS variables, radius, and neutral color palettes.

Quick Start

# Initialize shadcn in your Next.js / Vite project
npx shadcn@latest init

# Add components
npx shadcn@latest add button card dialog
import { Button } from "@/components/ui/button";

export default function Demo() {
  return (
    <Button variant="outline" size="lg">
      shadcn Button
    </Button>
  );
}

Core Concepts

Composable Dialog Primitive with Radix UI

Accessible modal dialogs adhering to open standards:

import * as React from "react";
import {
  Dialog,
  DialogContent,
  DialogDescription,
  DialogHeader,
  DialogTitle,
  DialogTrigger,
  DialogFooter,
} from "@/components/ui/dialog";
import { Button } from "@/components/ui/button";

export function ConfirmActionModal() {
  return (
    <Dialog>
      <DialogTrigger asChild>
        <Button variant="destructive">Delete Account</Button>
      </DialogTrigger>
      <DialogContent className="sm:max-w-[425px]">
        <DialogHeader>
          <DialogTitle>Are you absolutely sure?</DialogTitle>
          <DialogDescription>
            This action cannot be undone. This will permanently delete your
            account and remove your data.
          </DialogDescription>
        </DialogHeader>
        <DialogFooter>
          <Button variant="outline">Cancel</Button>
          <Button variant="destructive">Confirm Deletion</Button>
        </DialogFooter>
      </DialogContent>
    </Dialog>
  );
}

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
