| when_to_use | When designing microservices architecture, implementing service communication, or decomposing monoliths |
Service decomposition, communication, resilience, and orchestration patterns.
| Pattern | Description | Use When |
|---|---|---|
| Domain-Driven | Align services with bounded contexts | Complex business domains |
| Data-Ownership | Service owns its data store | Data isolation required |
| Team-Aligned | One service per team | Large organizations |
```yaml
routes:
``` Producer → Exchange → Queue → Consumer (Topic) (DLQ on failure) ```
Use async for: event propagation, eventual consistency, load leveling.
```typescript // Example with opossum const breaker = new CircuitBreaker(fetchUserProfile, { timeout: 3000, errorThresholdPercentage: 50, resetTimeout: 30000, }); ```
```typescript async function retryWithBackoff(fn, maxRetries = 3) { for (let i = 0; i < maxRetries; i++) { try { return await fn(); } catch (e) { await sleep(Math.pow(2, i) * 1000); } } throw new Error('Max retries exceeded'); } ```
| Pattern | Consistency | Complexity | Use When |
|---|---|---|---|
| Saga (orchestration) | Eventual | High | Complex multi-service transactions |
| Saga (choreography) | Eventual | Medium | Simple event chains |
| Event sourcing | Eventual | High | Audit trail, time travel |
| Shared database | Strong | Low | Anti-pattern, avoid |
Tools: Kong, AWS API Gateway, Envoy, NGINX.
Responsibilities: routing, auth, rate limiting, request transformation, load balancing.
backend-architect — single-service architectureevent-sourcing-architect — event sourcing patternskubernetes-architect — deployment patternsdeployment-engineer — CI/CD for microservicesTurns real agent failures, repeated prompts, team-specific workflows, and durable project lessons into better SDD skills or memory entries. Use when the user asks to create/update/refine skills, extract reusable lessons, improve skill routing, encode team process, or save patterns for future sessions.
Provides the vendored agent-style v0.3.5 prose rule pack as a portable Claude skill. Use when installing, syncing, applying, or auditing SDD Agent-Style support in another project, or when a style-review workflow needs the bundled rules.
Reviews Markdown prose against the pinned agent-style v0.3.5 rules and optionally writes a polished copy beside the source. Use for specs, ADRs, PR bodies, release notes, and technical docs when prose quality or evidence discipline matters.
Scans Markdown (.md) files for malicious code injection including XSS, prompt injection, script injection, obfuscated payloads, and supply chain attack vectors. Use when auditing .md files for security threats or when the user mentions scanning markdown for malicious content.
Provides .NET and ASP.NET Core patterns for REST APIs, Entity Framework, dependency injection, and middleware. Use when working with C# files (*.cs, *.csproj) or when the user mentions .NET, ASP.NET Core, C#, or Entity Framework.
Designs hybrid cloud architectures connecting on-premises infrastructure with public cloud services. Use when designing systems spanning on-prem and cloud, or when the user mentions hybrid cloud or multi-environment architecture.
