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

ui-styling 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 2d 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.

UI Styling Skill

Comprehensive skill for creating beautiful, accessible user interfaces combining shadcn/ui components, Tailwind CSS utility styling, and canvas-based visual design systems.

Reference

When to Use This Skill

Use when:

  • Building UI with React-based frameworks (Next.js, Vite, Remix, Astro)
  • Implementing accessible components (dialogs, forms, tables, navigation)
  • Styling with utility-first CSS approach
  • Creating responsive, mobile-first layouts
  • Implementing dark mode and theme customization
  • Building design systems with consistent tokens
  • Generating visual designs, posters, or brand materials
  • Rapid prototyping with immediate visual feedback
  • Adding complex UI patterns (data tables, charts, command palettes)

Core Stack

Component Layer: shadcn/ui

  • Pre-built accessible components via Radix UI primitives
  • Copy-paste distribution model (components live in your codebase)
  • TypeScript-first with full type safety
  • Composable primitives for complex UIs
  • CLI-based installation and management

Styling Layer: Tailwind CSS

  • Utility-first CSS framework
  • Build-time processing with zero runtime overhead
  • Mobile-first responsive design
  • Consistent design tokens (colors, spacing, typography)
  • Automatic dead code elimination

Visual Design Layer: Canvas

  • Museum-quality visual compositions
  • Philosophy-driven design approach
  • Sophisticated visual communication
  • Minimal text, maximum visual impact
  • Systematic patterns and refined aesthetics

Quick Start

Component + Styling Setup

Install shadcn/ui with Tailwind:

npx shadcn@latest init

CLI prompts for framework, TypeScript, paths, and theme preferences. This configures both shadcn/ui and Tailwind CSS.

Add components:

npx shadcn@latest add button card dialog form

Use components with utility styling:

import { Button } from "@/components/ui/button"
import { Card, CardHeader, CardTitle, CardContent } from "@/components/ui/card"

export function Dashboard() {
  return (
    <div className="container mx-auto p-6 grid gap-6 md:grid-cols-2 lg:grid-cols-3">
      <Card className="hover:shadow-lg transition-shadow">
        <CardHeader>
          <CardTitle className="text-2xl font-bold">Analytics</CardTitle>
        </CardHeader>
        <CardContent className="space-y-4">
          <p className="text-muted-foreground">View your metrics</p>
          <Button variant="default" className="w-full">
            View Details
          </Button>
        </CardContent>
      </Card>
    </div>
  )

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.
