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
