Extract domain models from monolithic codebases using DDD principles for microservices decomposition

General

What this skill does


# Domain Model Extractor Skill

Extracts domain models from monolithic codebases using Domain-Driven Design principles to support microservices decomposition.

## Purpose

Enable domain analysis for:
- Bounded context identification
- Aggregate detection
- Entity relationship mapping
- Domain event discovery
- Ubiquitous language extraction

## Capabilities

### 1. Bounded Context Identification
- Analyze code modules
- Identify domain boundaries
- Map team ownership
- Define context relationships

### 2. Aggregate Detection
- Find aggregate roots
- Map entity relationships
- Identify invariants
- Define consistency boundaries

### 3. Entity Relationship Mapping
- Extract entities
- Map relationships
- Identify value objects
- Document associations

### 4. Domain Event Discovery
- Find implicit events
- Map state changes
- Identify triggers
- Document event flows

### 5. Ubiquitous Language Extraction
- Build domain vocabulary
- Map term usage
- Identify synonyms
- Create glossary

### 6. Context Map Generation
- Map context relationships
- Identify integration patterns
- Document shared kernels
- Define anti-corruption layers

Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.
