Architecture Paradigm Router

This skill helps you select the right architecture paradigm(s) for your system, then routes you to the specific paradigm skill for implementation details.

Quick Scenario Router

Match your needs to the recommended paradigm:

Your Scenario	Primary Paradigm	Load Skill
Enterprise app with multiple teams	Microservices or Modular Monolith	`architecture-paradigm-microservices` or `architecture-paradigm-modular-monolith`
Complex business rules & testing	Functional Core, Imperative Shell	`architecture-paradigm-functional-core`
Real-time/event processing	Event-Driven Architecture	`architecture-paradigm-event-driven`
Legacy system modernization	Hexagonal (Ports & Adapters)	`architecture-paradigm-hexagonal`
Cloud-native/bursty workloads	Serverless	`architecture-paradigm-serverless`
ETL/data processing pipeline	Pipeline Architecture	`architecture-paradigm-pipeline`
Simple CRUD app	Layered Architecture	`architecture-paradigm-layered`
Command/query separation	CQRS + Event Sourcing	`architecture-paradigm-cqrs-es`

3-Step Selection Workflow

Step 1: Define Your Needs

Primary Concerns (select all that apply):

Testability: Isolate business logic →
```
functional-core
```
or
```
hexagonal
```
Team Autonomy: Independent deployment →
```
microservices
```
or
```
modular-monolith
```
Infrastructure Flexibility: Swap databases/frameworks →
```
hexagonal
```
Real-time Scaling: Variable loads with events →
```
event-driven
```
or
```
space-based
```
Simplicity: Maintainable without complexity →
```
layered
```
or
```
modular-monolith
```
Legacy Integration: Work with existing systems →
```
hexagonal
```
or
```
microkernel
```

System Context:

Team Size:
```
< 5
```
→ Layered/Functional Core |
```
5-15
```
→ Modular Monolith |
```
15-50
```
→ Microservices |
```
50+
```
→ Microservices/Space-Based
Domain Complexity:
```
Simple
```
→ Layered |
```
Moderate
```
→ Hexagonal/Modular Monolith |
```
Complex
```
→ Functional Core/CQRS |
```
Highly Complex
```
→ Microservices/Event-Driven

Step 2: Evaluate Paradigms

Based on your needs from Step 1, review these options:

For Testability & Business Logic

Load
```
architecture-paradigm-functional-core
```
- Isolates business logic from infrastructure
Load
```
architecture-paradigm-hexagonal
```
- Clear domain/infrastructure boundaries

For Team Autonomy

Load
```
architecture-paradigm-microservices
```
- Independent deployment and scaling
Load
```
architecture-paradigm-modular-monolith
```
- Team autonomy without distributed complexity

For Infrastructure Flexibility

Load
```
architecture-paradigm-hexagonal
```
- Swap infrastructure without domain changes

For Simplicity & Maintainability

Load
```
architecture-paradigm-layered
```
- Simple, well-understood separation

For Real-time Event Processing

Load
```
architecture-paradigm-event-driven
```
- Scalable, decoupled processing
Load
```
architecture-paradigm-space-based
```
- In-memory data grids for linear scalability

For Legacy Integration

Load
```
architecture-paradigm-microkernel
```
- Plugin architecture for extensible platforms
Load
```
architecture-paradigm-hexagonal
```
- Adapters for external systems

Step 3: Load Paradigm Skill for Implementation

Once you've selected your paradigm(s), load the specific skill for detailed guidance:

# Example: You selected Hexagonal Architecture
Skill(archetypes:architecture-paradigm-hexagonal)

The individual paradigm skill provides:

✅ Complete implementation guide
✅ ADR templates
✅ Migration checklist
✅ Code examples
✅ Testing strategies
✅ Risk assessments

Available Paradigm Skills

Paradigm	Complexity	Team Size	Best For	Skill Name
Functional Core	Medium	Small-Large	Complex business logic	`architecture-paradigm-functional-core`
Hexagonal	Medium	Small-Large	Infrastructure changes	`architecture-paradigm-hexagonal`
Layered	Low	Small-Medium	Simple domains	`architecture-paradigm-layered`
Modular Monolith	Medium	Medium-Large	Evolving systems	`architecture-paradigm-modular-monolith`
Microservices	High	Large	Complex domains	`architecture-paradigm-microservices`
Event-Driven	High	Medium-Large	Real-time processing	`architecture-paradigm-event-driven`
CQRS + ES	High	Medium-Large	Audit trails	`architecture-paradigm-cqrs-es`
Service-Based	Medium	Medium	Coarse-grained services	`architecture-paradigm-service-based`
Serverless	Medium	Small-Medium	Cloud-native/bursty	`architecture-paradigm-serverless`
Microkernel	Medium	Small-Medium	Plugin systems	`architecture-paradigm-microkernel`
Space-Based	High	Large	Linear scalability	`architecture-paradigm-space-based`
Pipeline	Low	Small-Medium	ETL workflows	`architecture-paradigm-pipeline`
Client-Server	Low	Small	Traditional apps	`architecture-paradigm-client-server`

Integration with Other Skills

Architecture Review: Use this skill first to select paradigms, then
```
/architecture-review
```
for evaluation
Implementation Planning: Select paradigms here, then
```
/writing-plans
```
for detailed task breakdown
Refactoring: Identify target paradigms here, then use paradigm-specific skills for migration strategies

Exit Criteria

At least one paradigm is selected with clear rationale
Specific paradigm skill has been loaded for detailed guidance
Ready to create ADR or implementation plan

Next Steps

Load the specific paradigm skill - Use

Skill(archetypes:architecture-paradigm-NAME)

Generate an ADR - Use the paradigm's ADR templates
Create implementation plan - Use paradigm's migration checklist
Set up monitoring - Track success metrics from paradigm guidance
