name: generating-components description: Generate production-ready React components using shadcn/ui, 21st.dev, and Tailwind CSS. Use when user asks for UI components, buttons, forms, cards, hero sections, or mentions design inspiration. allowed-tools: Read, Write, Edit, Glob, Grep, Task, mcp__magic__21st_magic_component_builder, mcp__magic__21st_magic_component_inspiration, mcp__magic__21st_magic_component_refiner, mcp__shadcn__search_items_in_registries, mcp__shadcn__view_items_in_registries, mcp__shadcn__get_item_examples_from_registries, mcp__shadcn__get_add_command_for_items user-invocable: true

Generating Components

APEX WORKFLOW (MANDATORY)

Phase A: ANALYZE

Task: explore-codebase
Prompt: "Analyze UI: components, colors, typography, spacing, animations"

Phase A: SEARCH INSPIRATION

// 21st.dev (MANDATORY FIRST)
mcp__magic__21st_magic_component_inspiration({
  message: "Create a hero section",
  searchQuery: "hero section glassmorphism"
})

// shadcn/ui
mcp__shadcn__search_items_in_registries({
  registries: ["@shadcn"],
  query: "button"
})

Phase P: PLAN

TodoWrite with file breakdown (<100 lines each):

• components/ui/HeroSection.tsx (~60 lines)
• components/ui/HeroBackground.tsx (~30 lines)

Phase E: CODE

Write component using:

• Design tokens from Phase A
• Inspiration from 21st.dev/shadcn
• Framer Motion animations
• WCAG 2.2 AA compliance

Phase X: VALIDATE

Task: sniper
Prompt: "Validate component: lint, accessibility, design consistency"

ANTI-AI SLOP (MANDATORY)

See: ../../references/typography.md, ../../references/color-system.md

Component Template

"use client";
import { motion } from "framer-motion";

const variants = {
  hidden: { opacity: 0, y: 20 },
  show: { opacity: 1, y: 0, transition: { staggerChildren: 0.1 } }
};

export function Component({ className }: { className?: string }) {
  return (
    <motion.div variants={variants} initial="hidden" animate="show">
      {/* Background from existing design tokens */}
      <div className="absolute inset-0 -z-10">
        <div className="absolute top-1/4 left-1/4 w-96 h-96 bg-primary/20 rounded-full blur-3xl" />
      </div>
      {/* Content */}
    </motion.div>
  );
}

Validation

[ ] Phase 0 completed (analyze existing)
[ ] Inspiration searched (21st.dev, shadcn)
[ ] Matches existing design tokens
[ ] No AI slop patterns
[ ] Framer Motion animations
[ ] Files < 100 lines
