Aget Design Architecture

aget-design-architecture

Design system architecture including components, relationships, and patterns. Addresses quality attributes and produces architectural artifacts.

Instructions

When this skill is invoked:

1. Understand Requirements

   • Gather functional requirements
   • Identify quality attributes (scalability, reliability, security, etc.)
   • Note constraints (technology, budget, timeline)

2. Decompose the System

   • Identify logical components
   • Define responsibilities (single responsibility)
   • Establish boundaries

3. Select Patterns

   • Choose appropriate architectural patterns:
     • Layered, Microservices, Event-Driven, etc.
   • Match patterns to requirements and constraints

4. Define Relationships

   • Document interfaces between components
   • Specify communication protocols
   • Map dependencies

5. Address Quality Attributes

   • Scalability: How system grows
   • Reliability: How system handles failure
   • Security: How system protects assets

Output Format

## Architecture Design: [System Name]

### Overview

[2-3 sentence description of the architecture]

### Components

| Component | Responsibility | Interface |
|-----------|---------------|-----------|
| [Name] | [What it does] | [API/Events/etc.] |

### Architecture Diagram

┌─────────────┐ ┌─────────────┐ │ Component A │────▶│ Component B │ └─────────────┘ └─────────────┘ │ ▼ ┌─────────────┐ │ Component C │ └─────────────┘

### Patterns Applied

| Pattern | Rationale |
|---------|-----------|
| [Pattern] | [Why chosen] |

### Quality Attributes

| Attribute | Approach |
|-----------|----------|
| Scalability | [How addressed] |
| Reliability | [How addressed] |
| Security | [How addressed] |

### Dependencies

A → B (sync API) B → C (async events)

### Risks & Trade-offs

- [Trade-off 1]: [What was traded for what]

Constraints

• C1: NEVER propose architecture without understanding requirements — architecture serves requirements
• C2: NEVER introduce unnecessary complexity — simplest solution meeting requirements preferred
• C3: NEVER ignore non-functional requirements — quality attributes are architectural drivers
