| Transport | 용도 | 특징 |
|---|---|---|
| TCP | 직접 통신 | 빠름, 간단 |
| Redis | Pub/Sub | 경량, 메모리 기반 |
| RabbitMQ | 메시지 브로커 | 신뢰성, 영속성 |
| gRPC | RPC | 고성능, 스트리밍 |
| NATS | 클라우드 | 확장성, 빠름 |
// 1. TCP 서버 (Message Pattern)
@Controller()
export class MathController {
@MessagePattern({ cmd: 'sum' })
accumulate(data: number[]) {
return data.reduce((a, b) => a + b, 0);
}
}
// 2. TCP 클라이언트
@Module({
imports: [
ClientsModule.register([{
name: 'MATH_SERVICE',
transport: Transport.TCP,
options: { host: 'localhost', port: 3001 },
}]),
],
})
// 3. RabbitMQ (Event Pattern)
@EventPattern('user_created')
handleUserCreated(data: UserCreatedEvent) {
// 이벤트 처리
}

| Step | 작업 | 주요 활동 |
|---|---|---|
| 1. 분석 | Transport 선택 | TCP/Redis/RabbitMQ/gRPC 결정 |
| 2. 설계 | 서비스 경계 | Message Contract, 실패 처리 |
| 3. 구현 | 서버/클라이언트 | @MessagePattern, @EventPattern |
| 4. 검증 | 통신 테스트 | 서비스 간 호출, 에러 핸들링 |
| 5. 출력 | 결과 반환 | JSON 형식 응답 |
| Issue | Cause | Solution |
|---|---|---|
| Connection timeout | Service down | Retry logic, Circuit breaker |
| Message loss | Broker failure | Persistent queues |
| Serialization error | Schema mismatch | Version contracts |
| Memory leak | Unclosed connections | Close clients properly |
Use this agent when analyzing conversation transcripts to find behaviors worth preventing with hooks. Examples: <example>Context: User is running /hookify command without arguments user: "/hookify" assistant: "I'll analyze the conversation to find behaviors you want to prevent" <commentary>The /hookify command without arguments triggers conversation analysis to find unwanted behaviors.</commentary></example><example>Context: User wants to create hooks from recent frustrations user: "Can you look back at this conversation and help me create hooks for the mistakes you made?" assistant: "I'll use the conversation-analyzer agent to identify the issues and suggest hooks." <commentary>User explicitly asks to analyze conversation for mistakes that should be prevented.</commentary></example>
