Use when creating or updating a Serinus app entrypoint, bootstrapping with serinus.createApplication() or serinus.createMinimalApplication(), configuring host/port, globalPrefix, versioning, or adding global hooks, pipes, and exception filters before serve().

Use when building Serinus microservices with createMicroservice(), RpcController, RpcRoute, transport adapters, ClientsModule, or gRPC integration via serinus_microservices.

Use when the user is building a Serinus app with serinus.createMinimalApplication() and wants functional route registration, direct provider/module imports, or middleware configuration without defining full controller classes.

Use when adding or refactoring Serinus modules, controllers, and REST routes. Enforces the framework's modular structure, route registration with on(...), and correct RequestContext usage for params, query, and typed request bodies.

Use when defining Serinus providers, dependency injection, module exports, lifecycle hooks, or custom provider registrations such as Provider.composed, Provider.forClass, and Provider.forValue.

Use when adding or modifying Serinus middlewares, hooks, pipes, or exception filters so request flow, validation, and cross-cutting behavior are implemented in the correct layer.
