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
