SkillSpector: 23 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00027 | $0.07993 |
| Opus 5 | $0.00014 | $0.03997 |
| Sonnet 5 | $0.00005 | $0.01599 |
| Haiku 4.5 | $0.00003 | $0.00799 |
Grade A, and why
shadcn-ui 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 10d 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 - Component Library
Summary
shadcn/ui is a collection of re-usable React components built with Radix UI primitives and styled with Tailwind CSS. Unlike traditional component libraries, shadcn/ui components are copied directly into your project, giving you full ownership and customization control. Components are accessible, customizable, and open source.
Core Philosophy: Copy-paste components, not npm packages. You own the code.
When to Use
Use shadcn/ui when:
- Building React applications with Tailwind CSS
- Need accessible, production-ready UI components
- Want full control over component code and styling
- Prefer composition over configuration
- Building with Next.js, Vite, Remix, or Astro
- Need dark mode support out of the box
- Want TypeScript-first components
Don't use when:
- Not using Tailwind CSS (core styling dependency)
- Need legacy browser support (uses modern CSS features)
- Prefer packaged npm libraries over code ownership
- Building non-React frameworks (Vue, Svelte, Angular)
Quick Start
Installation
# Initialize shadcn/ui in your project
npx shadcn@latest init
# Follow interactive prompts:
# - TypeScript? (yes/no)
# - Style: Default/New York
# - Base color: Slate/Gray/Zinc/Neutral/Stone
# - CSS variables: (yes/no)
# - React Server Components: (yes/no)
# - components.json location
# - Tailwind config location
# - CSS file location
# - Import alias (@/components)
Add Your First Component
# Add individual components
npx shadcn@latest add button
npx shadcn@latest add card
npx shadcn@latest add dialog
# Add multiple components at once
npx shadcn@latest add button card dialog form input
Basic Usage
import { Button } from "@/components/ui/button"
import { Card, CardHeader, CardTitle, CardContent } from "@/components/ui/card"
export default function Example() {
return (
<Card>
<CardHeader>
<CardTitle>Welcome</CardTitle>
</CardHeader>
<CardContent>
<Button>Click me</Button>
</CardContent>
</Card>
)
}
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.

shadcn-ui is a skill published in the GitHub repository Hainrixz/claude-webkit (227 stars, last pushed 19d ago), licensed MIT. It adds 27 tokens to every session and 7,993 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
