assembling-components

name	assembling-components
description	Assembles component outputs from AI Design Components skills into unified, production-ready component systems with validated token integration, proper import chains, and framework-specific scaffolding. Use as the capstone skill after running theming, layout, dashboard, data-viz, or feedback skills to wire components into working React/Next.js, Python, or Rust projects.

Assembling Components

Purpose

This skill transforms the outputs of AI Design Components skills into production-ready applications. It provides library-specific context for our token system, component patterns, and skill chain workflow - knowledge that generic assembly patterns cannot provide. The skill validates token integration, generates proper scaffolding, and wires components together correctly.

When to Use

Activate this skill when:

• Completing a skill chain workflow (theming → layout → dashboards → data-viz → feedback)
• Generating new project scaffolding for React/Vite, Next.js, FastAPI, Flask, or Rust/Axum
• Validating that all generated CSS uses design tokens (not hardcoded values)
• Creating barrel exports and wiring component imports correctly
• Assembling components from multiple skills into a unified application
• Debugging integration issues (missing entry points, broken imports, theme not switching)
• Preparing generated code for production deployment

Skill Chain Context

This skill understands the output of every AI Design Components skill:

Token Validation

Run Validation Script (Token-Free Execution)

# Basic validation
python scripts/validate_tokens.py src/styles

# Strict mode with fix suggestions
python scripts/validate_tokens.py src --strict --fix-suggestions

# JSON output for CI/CD
python scripts/validate_tokens.py src --json

Our Token Naming Conventions

/* Colors - semantic naming */
--color-primary: #FA582D;          /* Brand primary */
--color-success: #00CC66;          /* Positive states */

Validation Rules

Must Use Tokens (Errors)	Example Fix
Colors	#FA582D → var(--color-primary)
Spacing (≥4px)	16px → var(--spacing-md)
Font sizes	14px → var(--font-size-sm)

Should Use Tokens (Warnings)	Example Fix
Border radius	8px → var(--radius-md)
Shadows	0 4px... → var(--shadow-md)
Z-index (≥100)	1000 → var(--z-dropdown)

• Growing ecosystem

Choose Actix Web when:

• Maximum performance required
• Actor model benefits your use case
• More mature ecosystem

Implementation Approach

1. Validate Token Integration

Before assembly, check all CSS uses tokens:

python scripts/validate_tokens.py <component-directory>

Fix any violations before proceeding.

2. Generate Project Scaffolding

React/Vite:

// src/main.tsx - Entry point
import { StrictMode } from 'react'
import { createRoot } from 'react-dom/client'
import { ThemeProvider } from '@/context/theme-provider'
import App from './App'
import './styles/tokens.css'   // FIRST - token definitions
import './styles/globals.css'  // SECOND - global resets

createRoot(document.getElementById('root')!).render(
  <StrictMode>
    <ThemeProvider>
      <App />
    </ThemeProvider>
  </StrictMode>,
)

index.html:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>{{PROJECT_TITLE}}</title>
  </head>
  <body>
    <div id="root"></div>
    <script type="module" src="/src/main.tsx"></script>
  </body>
</html>

3. Wire Components Together

Theme Provider:

// src/context/theme-provider.tsx
import { createContext, useContext, useEffect, useState } from 'react'

type Theme = 'light' | 'dark' | 'system'

const ThemeContext = createContext<{
  theme: Theme
  setTheme: (theme: Theme) => void
} | undefined>(undefined)

export function ThemeProvider({ children }: { children: React.ReactNode }) {
  const [theme, setTheme] = useState<Theme>('system')

  useEffect(() => {
    const root = document.documentElement
    const systemTheme = window.matchMedia('(prefers-color-scheme: dark)').matches
      ? 'dark' : 'light'
    root.setAttribute('data-theme', theme === 'system' ? systemTheme : theme)
    localStorage.setItem('theme', theme)
  }, [theme])

  return (
    <ThemeContext.Provider = ,  }}>
      {children}
    
  )
}

   = () => {
   context = ()
   (!context)   ()
   context
}

Barrel Exports:

// src/components/ui/index.ts
export { Button } from './button'
export { Card } from './card'

// src/components/features/dashboard/index.ts
export { KPICard } from './kpi-card'
export { DonutChart } from './donut-chart'
export { Dashboard } from './dashboard'

4. Configure Build System

vite.config.ts:

import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
import path from 'path'

export default defineConfig({
  plugins: [react()],
  resolve: {
    alias: {
      '@': path.resolve(__dirname, './src'),
    },
  },
})

tsconfig.json:

{
  "compilerOptions": {
    "target": "ES2020",
    "lib": ["ES2020", "DOM", "DOM.Iterable"],
    "module": "ESNext",
    "moduleResolution": "bundler",
    "jsx": "react-jsx",
    "strict": true,
    "baseUrl": ".",
    "paths": { "@/*": ["./src/*"] }
  },
  "include": ["src"]
}

Cross-Skill Integration

Using Theming Components

// Import tokens first, components inherit token values
import './styles/tokens.css'

// Use ThemeProvider at root
<ThemeProvider>
  <App />
</ThemeProvider>

Using Dashboard Components

// Components from creating-dashboards skill
import { Dashboard, KPICard } from '@/components/features/dashboard'

// Wire with data
<Dashboard>
  <KPICard
    label="Total Threats"
    value={1234}
    severity="critical"
    trend={{ value: 15.3, direction: 'up' }}
  />
</Dashboard>

Using Data Visualization

// Charts from visualizing-data skill
import { DonutChart } from '@/components/charts'

// Charts use --chart-color-* tokens automatically
<DonutChart
  data={threatData}
  title="Threats by Severity"
/>

Using Feedback Components

// From providing-feedback skill
import { Toast, Spinner, EmptyState } from '@/components/feedback'

// Wire toast notifications
<ToastProvider>
  <App />
</ToastProvider>

// Use spinner for loading states
{isLoading ? <Spinner /> : <Dashboard />}

Integration Checklist

Before delivery, verify:

• Token file exists (tokens.css) with all 7 categories
• Token import order correct (tokens.css → globals.css → components)
• No hardcoded values (run validate_tokens.py)
• Theme toggle works (data-theme attribute switches)
• Reduced motion supported (@media (prefers-reduced-motion))
• Build completes without errors
• Types pass (TypeScript compiles)
• Imports resolve (no missing modules)
• Barrel exports exist for each component directory

Application Assembly Workflow

1. Validate Components: Run validate_tokens.py on all generated CSS
2. Choose Framework: React/Vite, Next.js, FastAPI, or Rust based on requirements
3. Generate Scaffolding: Create project structure and configuration
4. Wire Imports: Set up entry point, import chain, barrel exports
5. Add Providers: ThemeProvider, ToastProvider at root
6. Connect Components: Import and compose feature components
7. Configure Build: vite.config, tsconfig, package.json
8. Final Validation: Build, type-check, lint
9. Document: README with setup and usage instructions
