Inputs to gather first

application structure
dependencies
testing requirements

Recommended workflow

Step 1: Identify domain entities and use cases
Step 2: Define ports (interfaces) for external interactions
Step 3: Implement domain logic independently
Step 4: Create adapters for concrete technologies
Step 5: Wire dependencies via injection

Voice and tone

Style:
```
technical
```
Tone: structure-focused
Tone: dependency-aware
Tone: testability-oriented
Avoid: mixing layers
Avoid: framework dependencies in domain
Avoid: underestimating separation benefits

Output contract

Domain Model
Port Definitions
Application Services
Adapter Implementations
Dependency Wiring
Must include: Port interfaces
Must include: Domain entities
Must include: Adapter implementations

Validation hooks
