六边形架构（端口与适配器）使业务逻辑独立于框架、传输层和持久化细节。核心应用依赖于抽象端口，而适配器在边缘实现这些端口。
当需求涉及边界、领域驱动设计、重构紧耦合服务，或将应用逻辑与特定库解耦时，使用此技能。
出站端口接口通常位于应用层（仅当抽象真正属于领域层时才位于领域层），而基础设施适配器实现它们。
依赖方向始终向内：
定义具有清晰输入和输出DTO的单个用例。将传输细节（Express req、GraphQL context、任务负载包装器）保持在此边界之外。
将每个副作用识别为端口：
UserRepositoryPort）BillingGatewayPort）LoggerPort、ClockPort）端口应建模能力，而非技术。
用例类/函数通过构造函数/参数接收端口。它验证应用层不变量，协调领域规则，并返回纯数据结构。
实例化适配器，然后将其注入用例。保持此连接集中化，以避免隐藏的服务定位器行为。

在不同生态系统中使用相同的边界规则；仅语法和连接方式发生变化。

Orchestrate building a brand-new feature end to end — research, plan, TDD implementation, review, and gated commit — by delegating each phase to the matching ECC agent. Use when adding a capability that does not exist yet.
Orchestrate bootstrapping a working MVP from a design or spec document — ingest the doc, plan thin vertical slices, scaffold the first end-to-end slice, then TDD-implement, review, and gated commit. Use to turn an SDD/PRD into a running starting point.
Orchestrate altering an existing, working feature to new desired behavior — update its tests to the new spec, change the implementation to match, review, and gated commit. Use when behavior is not broken but should be different.
Orchestrate fixing a bug — reproduce it as a failing regression test, fix to green, review, and gated commit — by delegating each phase to the matching ECC agent. Use when existing behavior is broken or wrong.
Shared orchestration engine for the orch-* skill family. Defines the gated Research-Plan-TDD-Review-Commit pipeline, the size classifier, the agent map, and the two human gates that the orch-* operation skills delegate to. Not usually invoked directly.
