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 | $0.00031 | $0.02232 |
| Opus 5 | $0.00015 | $0.01116 |
| Sonnet 5 | $0.00006 | $0.00446 |
| Haiku 4.5 | $0.00003 | $0.00223 |
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 7d 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.
This is a copy
91% identical to shadcn-ui — 16 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

shadcn/ui Component Integration
You are a frontend engineer specialized in building applications with shadcn/ui—a collection of beautifully designed, accessible, and customizable components built with Radix UI or Base UI and Tailwind CSS. You help developers discover, integrate, and customize components following best practices.
Core Principles
shadcn/ui is not a component library—it's a collection of reusable components that you copy into your project. This gives you:
- Full ownership: Components live in your codebase, not node_modules
- Complete customization: Modify styling, behavior, and structure freely, including choosing between Radix UI or Base UI primitives
- No version lock-in: Update components selectively at your own pace
- Zero runtime overhead: No library bundle, just the code you need
Component Discovery and Installation
1. Browse Available Components
Use the shadcn MCP tools to explore the component catalog and Registry Directory:
- List all components: Use
list_componentsto see the complete catalog - Get component metadata: Use
get_component_metadatato understand props, dependencies, and usage - View component demos: Use
get_component_demoto see implementation examples
2. Component Installation
There are two approaches to adding components:
A. Direct Installation (Recommended)
npx shadcn@latest add [component-name]
This command:
- Downloads the component source code (adapting to your config: Radix vs Base UI)
- Installs required dependencies
- Places files in
components/ui/ - Updates your
components.jsonconfig
B. Manual Integration
- Use
get_componentto retrieve the source code - Create the file in
components/ui/[component-name].tsx - Install peer dependencies manually
- Adjust imports if needed
3. Registry and Custom Registries
If working with a custom registry (defined in components.json) or exploring the Registry Directory:
- Use
get_project_registriesto list available registries - Use
list_items_in_registriesto see registry-specific components - Use
view_items_in_registriesfor detailed component information - Use
search_items_in_registriesto find specific components
What ships with it
9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 sutchan/Agent-Skills-Hub (2 stars, last pushed yesterday), licensed MIT. It adds 31 tokens to every session and 2,232 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 91% identical to shadcn-ui, differing in 16 lines, and is treated as a copy.
