shadcn/ui for React

Beautiful, accessible components built on Radix UI with Tailwind CSS styling.

Agent Workflow (MANDATORY)

Before ANY implementation, use TeamCreate to spawn 3 agents:

fuse-ai-pilot:explore-codebase - Analyze existing components and patterns
fuse-ai-pilot:research-expert - Verify latest shadcn/ui docs via Context7/Exa
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, CRA)
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

Why shadcn/ui

Feature	Benefit
Copy/paste model	Components copied to your project, full ownership
Radix UI foundation	Accessibility built-in, unstyled primitives
Tailwind CSS styling	Utility-first, easy customization
TanStack Form ready	Modern form library with Field pattern
Lucide icons	Consistent, customizable icon set

Critical Rules

NEVER create components manually - Always install with bunx --bun shadcn@latest add
TanStack Form only - NOT React Hook Form for all form implementations
Radix UI primitives - Components built on Radix (NOT Base UI)
Lucide icons - Default icon library, NOT Remix icons or others
Field pattern - Use Field, FieldLabel, FieldError for form fields
SOLID paths - Components at @/modules/cores/shadcn/components/ui/

Architecture

Component Foundation

Radix UI - Headless, accessible primitives (Dialog, Select, Popover, Tabs)
Tailwind CSS v4 - Styling via utility classes, CSS-first config
class-variance-authority - Variant management for component styles
clsx + tailwind-merge - Conditional class composition via cn() utility

Project Structure

Components installed to @/modules/cores/shadcn/components/ui/ following SOLID architecture. Utils at @/modules/cores/lib/utils.ts with cn() helper function.

MCP Server Integration

Create .mcp.json at project root for Claude Code integration with shadcn registry.

Available MCP Tools

mcp__shadcn__search_items_in_registries - Search available components
mcp__shadcn__view_items_in_registries - View component source code
mcp__shadcn__get_item_examples_from_registries - Get usage examples
mcp__shadcn__get_add_command_for_items - Get installation commands

See installation.md for complete MCP setup.

Component Categories

Category	Components	Primary Reference
Setup	Init, configuration, theming, icons	installation.md
Forms	Button, Input, Field, Select, Checkbox, Switch, Slider	field-patterns.md
Overlay	Dialog, Sheet, Drawer, Popover, Tooltip, HoverCard	dialog.md
Feedback	Alert, Toast (Sonner), Progress, Skeleton, Spinner	toast.md
Data Display	Table, Badge, Avatar, Calendar, Chart, Carousel	table.md
Navigation	Breadcrumb, DropdownMenu, Command, Sidebar, Tabs	sidebar.md
Layout	Card, Accordion, Separator, ScrollArea, Resizable	card.md

Best Practices

Field components - Use new Field pattern for consistent form field structure
Client Components - React apps are client-side by default
Sonner for toasts - Modern toast notifications over legacy toast
MCP tools first - Use mcp__shadcn__* to explore before implementing
Theming via CSS variables - Customize colors in index.css :root
Accessibility - Rely on Radix UI keyboard navigation and ARIA
