Scaffold Domain Skill

@./../_shared/ddd-patterns.md @./../_shared/test-templates.md

Purpose: Generate complete DDD 4-layer architecture structure for a new domain

When to Use

Agents should invoke this skill when:

• Starting new domain implementation
• During v0.1.x PROJECT phase
• Implementing feature in new domain
• Refactoring existing code to DDD

Quick Start

Generated Structure

app/{domain}/
├── _repositories/
│   ├── __tests__/
│   └── index.ts
├── _api-clients/
│   └── index.ts
├── _hooks/
│   ├── __tests__/
│   └── index.ts
├── _components/
│   ├── __tests__/
│   └── index.ts
└── page.tsx

Usage

// Agent invokes this skill
skill: scaffoldDomain("posts");

// Creates:
// app/posts/_repositories/ + _api-clients/ + _hooks/ + _components/ + page.tsx
// + all test boilerplates + index.ts exports

Standard Components Created

Each domain gets 6 standard components:

| Component | Purpose | |-----------|---------| | {Domain}Header | Page header with title and actions | | {Domain}Filter | Filter controls (search, sort) | | {Domain}List | Main list/grid display | | {Domain}EmptyState | Empty state UI | | {Domain}LoadingState | Loading skeletons | | {Domain}ErrorState | Error display |

Critical Rules

1. All 4 Layers: Must create repositories, api-clients, hooks, components
2. Test Directories: Always create __tests__/ for testable layers
3. Index Exports: Always create index.ts for clean imports
4. Factory Pattern: API clients must export singleton instances

Constitution Compliance

• Principle I: DDD Architecture (4-layer structure)
• Creates proper separation of concerns
• Follows established patterns

Dependencies

• File system operations
• Template files (optional, can use inline templates)
