react-shadcn

react-shadcn is a skill for Claude Code from fusengine/agents. It costs 35 tokens per session (2,455 once invoked), scanned A, a copy of nextjs-shadcn, MIT.

A guide to building reusable interface components for React single-page apps with shadcn/ui, Radix UI, and Tailwind CSS. It covers forms, dialogs, drawers, menus, tables, notifications, and other common interface elements.

In plain words
What is it for?
Use it when building React forms, overlays, navigation, data tables, command menus, loading states, or toast notifications.
Why use it?
It helps create consistent, customizable interface pieces without designing every common control from scratch, while keeping accessibility patterns in view.

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

react-shadcn 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 22d 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.

Origin

This is a copy

88% identical to nextjs-shadcn — 21 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.

How it starts

The opening of the file, as written. The whole thing — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Requires detecting the base from components.json before writing any component code, installing components via bunx --bun shadcn@latest add (never hand-written) to @/modules/cores/shadcn/components/ui/, and covers MCP registry tools (mcp__shadcn__*) for discovering components before implementing. This is the plain-React variant of shadcn/ui — for Next.js App Router see nextjs-shadcn instead.

shadcn/ui for React

Accessible, copy-in components on Base UI, Radix UI or React Aria primitives, styled with Tailwind CSS v4.

Agent Workflow (MANDATORY)

Before ANY implementation, spawn 3 agents in parallel, one Agent call each with a name:

  1. fuse-ai-pilot:explore-codebase - Analyze existing components and patterns
  2. fuse-ai-pilot:research-expert - Verify latest shadcn/ui docs via Context7/Exa
  3. mcp__shadcn__* - Search registry for component availability

After implementation, run fuse-ai-pilot:sniper for validation.

Overview

When to Use

  • Building UI components for React applications (Vite)
  • Need accessible, customizable form components (inputs, selects, checkboxes)
  • Implementing dialogs, sheets, drawers, or overlay patterns
  • Creating data tables with sorting, filtering, and pagination
  • Building navigation menus, sidebars, or command palettes
  • Need toast notifications or alert feedback components

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.
