## Description

Create or evaluate an architecture decision record (ADR). Use when choosing between technologies (e.g., Kafka vs SQS), documenting a design decision with trade-offs and consequences, reviewing a system design proposal, or designing a new component from requirements and constraints.

Create an Architecture Decision Record (ADR) or evaluate a system design.

## Usage

```
/architecture $ARGUMENTS
```

## Modes

**Create an ADR**: "Should we use Kafka or SQS for our event bus?"
**Evaluate a design**: "Review this microservices proposal"
**System design**: "Design the notification system for our app"

See the **system-design** skill for detailed frameworks on requirements gathering, scalability analysis, and trade-off evaluation.

## Output, ADR Format
