Async communication patterns using message brokers and task queues. Use when building event-driven systems, background job processing, or service decoupling. Covers Kafka (event streaming), RabbitMQ (complex routing), NATS (cloud-native), Redis Streams, Celery (Python), BullMQ (TypeScript), Temporal (workflows), and event sourcing patterns.
Go interface design patterns: implicit interfaces, consumer-side definition, interface compliance verification, composition, the accept-interfaces-return-structs principle, and common pitfalls. Use when designing interfaces, decoupling packages, defining contracts, reviewing interface usage, or refactoring for testability. Trigger examples: "design interface", "accept interfaces return structs", "interface compliance", "consumer-side interface", "interface composition". Do NOT use for HTTP handler patterns (use go-api-design) or general code review (use go-code-review).
SOLID principles, hexagonal architecture, ports and adapters, and DDD tactical patterns for maintainable backends. Use when implementing clean architecture, decoupling services, separating domain logic, or creating testable architecture.
Asynchronous message queues for reliable background processing. Load when offloading background tasks, batch processing messages, implementing retry logic with dead letter queues, rate limiting upstream APIs, or decoupling producers from consumers.
Decide a public API's language-SDK portfolio - which languages get official SDKs and in what order, generated vs handwritten build model, official and community support tiers with a promotion gate, SDK deprecation and end-of-life, and decoupling SDK SemVer from API versioning and release cadence. Use whenever the user mentions client libraries, SDKs, which languages to support first, an SDK generator (Stainless, Fern, OpenAPI Generator), community SDKs, or sunsetting an SDK - even if they never say "SDK portfolio". Portfolio strategy only, not single-SDK ergonomics or registry publishing. Do NOT use for whether to offer SDKs as a surface at all - use samber/developer-platform-skills@api-integration-surface-strategy instead.
Expert Coordinator pattern decisions for iOS/tvOS: when coordinators add value vs overkill, parent-child coordinator hierarchy design, SwiftUI vs UIKit coordinator differences, and flow completion handling. Use when designing navigation architecture, implementing multi-step flows, or decoupling views from navigation. Trigger keywords: Coordinator, navigation, flow, parent coordinator, child coordinator, deep link, routing, navigation hierarchy, flow completion
Apply Gang of Four design patterns to solve architectural problems in TypeScript. Use when refactoring code architecture, implementing extensible systems, decoupling components, or following SOLID principles. Covers all 22 GoF patterns: Creational (Factory Method, Abstract Factory, Builder, Prototype, Singleton), Structural (Adapter, Bridge, Composite, Decorator, Facade, Flyweight, Proxy), and Behavioral (Chain of Responsibility, Command, Iterator, Mediator, Memento, Observer, State, Strategy, Template Method, Visitor).
Queue and PubSub patterns, background fibers, and graceful shutdown. Use for decoupling producers/consumers.
Builds, runs, debugs, and operates event-driven applications using EventBridge Event Bus - a managed, centrally governed publish/subscribe event bus that an organization can share across many teams and accounts. Applicable when workloads need event-driven architectures, decoupling, choreography, asynchronous integration, pub/sub, fan-out, event ordering, delivered in sequence, event router, event broker, event bus, event store, event retention, event replay, deduplication, avro, protobuf, cloudevents, uses events or messages. Designed as a centrally managed event bus platform allowing governance and control - such as subscriber control, revocation, per-account throttling - while giving application owners flexibility across an organization spanning multiple accounts, with end-to-end open-standards observability and cost allocation. Also helps reduce costs in high fan-out scenarios where multi-account forwarding adds cost. A serverless, managed alternative to self-managed event streaming platforms.
Evaluate project specifications at inception (Step One), deterministically assess Scale & Load, Domain Decoupling, and Resource Intensity vectors, and automatically enforce a distributed Microservices Architecture when warranted, preventing monolith scaffolding.
Decouple methods that execute tasks by sending commands to a commander object.
