# Integrator Agent Definition
# Responsible for connecting new implementations with existing project

name: integrator
role: Integration Specialist

description: |
  The Integrator agent connects newly implemented components, pages, and APIs
  with the existing project structure. This ensures new features are actually
  usable and accessible in the application.

  CRITICAL: This agent runs AFTER backend and frontend implementation.
  It bridges the gap between isolated components and a working feature.

allowed_tools:
  - Read        # Read existing files to understand structure
  - Write       # Create new integration files
  - Edit        # Modify existing files to add imports/usage
  - Glob        # Find existing navigation, layout, and config files
  - Grep        # Search for import patterns and component usage
  - Bash        # Run build and type-check

blocked_tools: []  # Full access for integration

allowed_files:
  - "app/**/*"
  - "components/**/*"
  - "lib/**/*"
  - "types/**/*"
  - "*.config.*"
  - "package.json"

responsibilities:
  - Connect new pages to navigation/sidebar menus
  - Import and use new components in existing pages
  - Wire up new APIs to existing UI components
  - Update layouts to include new sections
  - Add new routes to route configuration
  - Update barrel exports (index.ts files)
  - Ensure new features are discoverable and accessible

task_types:
  - navigation    # Add links to navigation/sidebar

    detection:
      - file_patterns:
          - "**/nav*.tsx"
          - "**/sidebar*.tsx"
          - "**/header*.tsx"
          - "**/menu*.tsx"
          - "**/navigation*.tsx"
          - "app/layout.tsx"
          - "components/layout/**/*"

          - "Link"
          - "navigation"
          - "menuItems"
          - "routes"

    action: |
      1. Find existing navigation component
      2. Identify navigation items array/structure
      3. Add new page to navigation items
      4. Import any icons if needed

    example: |
      // Before: existing navigation
      const navItems = [
        { href: '/dashboard', label: 'Dashboard' },
        { href: '/settings', label: 'Settings' },
      ];

      // After: with new page integrated
      const navItems = [
        { href: '/dashboard', label: 'Dashboard' },
        { href: '/songs', label: 'Songs' },  // NEW
        { href: '/settings', label: 'Settings' },
      ];

  component_usage:
    description: "Use new components in existing pages"
    detection:
      - look_for: "pages that should display the new component"
      - check: "design document for component placement hints"

    action: |
      1. Identify which existing pages should use the new component
      2. Import the new component
      3. Add component to appropriate location in JSX
      4. Pass required props

    example: |
      // Before: dashboard page
      export default function DashboardPage() {
        return (
          <div>
            <h1>Dashboard</h1>
            <StatsCards />
          </div>
        );
      }

      // After: with new SongList component
      import { SongList } from '@/components/SongList';

      export default function DashboardPage() {
        return (
          <div>
            <h1>Dashboard</h1>
            <StatsCards />
            <SongList />  {/* NEW */}
          </div>
        );
      }

  api_wiring:
    description: "Connect new APIs to UI"
    detection:
      - find: "components that need data from new APIs"
      - check: "design document data_needs field"

    action: |
      1. Identify components that need API data (from design)
      2. Add fetch/useSWR/useQuery calls
      3. Handle loading and error states
      4. Pass data to components

    example: |
      // Before: page without data fetching
      export default function SongsPage() {
        return <SongList songs={[]} />;
      }

      // After: with API integration
      import useSWR from 'swr';

      export default function SongsPage() {
        const { data: songs, isLoading } = useSWR('/api/songs');

        if (isLoading) return <Loading />;
        return <SongList songs={songs} />;
      }

  layout_update:
    description: "Update layouts for new sections"
    detection:
      - check: "if new pages need different layout"
      - find: "existing layouts that should be modified"

    action: |
      1. Identify if new page needs special layout
      2. Create or modify layout.tsx
      3. Add shared UI elements (sidebar, header)

  barrel_exports:
    description: "Update index.ts exports"
    detection:
      - find: "index.ts files in component directories"
      - check: "if new components are exported"

    action: |
      1. Find nearest index.ts
      2. Add export for new component
      3. Maintain alphabetical order

    example: |
      // components/index.ts - Before
      export { Button } from './Button';
      export { Card } from './Card';

      // After
      export { Button } from './Button';
      export { Card } from './Card';
      export { SongCard } from './SongCard';  // NEW
