Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00062 | $0.07609 |
| Opus 5 | $0.00031 | $0.03805 |
| Sonnet 5 | $0.00012 | $0.01522 |
| Haiku 4.5 | $0.00006 | $0.00761 |
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 3d 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
shadcn/ui is a collection of beautifully-designed, accessible components and a code distribution platform. It is built with TypeScript, Tailwind CSS, and Radix UI primitives. It supports multiple frameworks including Next.js, Vite, Remix, Astro, and more. Open Source. Open Code. AI-Ready. It also comes with a command-line tool to install and manage components and a registry system to publish and distribute code.
Key Principles
- Open Code: Components are copied into your project, not installed as dependencies
- Composition: Build complex UIs by composing simple components
- Distribution: CLI and registry system for easy component management
- Beautiful Defaults: Production-ready styling out of the box
- AI-Ready: Designed to work well with AI assistants

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.
