Design e Frontend

Guia completo para armazenamento em nuvem CloudBase usando o Web SDK (@cloudbase/js-sdk) - upload, download, URLs temporárias, gerenciamento de arquivos e melhores práticas.

Guia a criação de user stories ágeis e arquivos de feature Gherkin, incluindo critérios de aceitação e cenários BDD. Utilize para solicitações como 'criar uma user story' ou 'escrever uma user story'.

Use when you need to design, review, or improve validation in Quarkus applications — including Bean Validation on JAX-RS resources, @Valid on parameters and CDI beans, constraint groups, @ConfigMapping validation, custom constraints, nested DTO validation, and ExceptionMapper-based error mapping. This should trigger for requests such as Add validation support in Quarkus; Review Quarkus validation

Use when you need to implement acceptance tests from a Gherkin .feature file for Micronaut applications — @acceptance scenarios, @MicronautTest, HttpClient, BaseAcceptanceTest with TestPropertyProvider for Testcontainers and WireMock, *AT suffix, Failsafe. Requires the .feature file in context. This should trigger for requests such as Implement Micronaut acceptance tests from a Gherkin feature fil

Use when building or reviewing core Quarkus applications with CDI beans and scopes, SmallRye Config and profiles, lifecycle, interceptors and events, virtual threads, and test-friendly design. This should trigger for requests such as Review Java code for Quarkus application structure and CDI; Apply best practices for Quarkus configuration and beans; Improve CDI interceptors, events, or programmati

Use when you need Kafka messaging in Quarkus with SmallRye Reactive Messaging — including channel/topic design, build-time Jackson serialization, typed @Channel/@Incoming, ack/failure strategies, retries/DLQ, idempotency, Dev Services, and Testcontainers integration tests. This should trigger for requests such as Add Kafka in Quarkus; Review Reactive Messaging consumers; Improve failure handling f

Facilita a descoberta conversacional para criar Registros de Decisão Arquitetural (ADRs) para requisitos não funcionais, utilizando o modelo de qualidade ISO/IEC 25010:2023. Esta skill é usada para documentar atributos de qualidade, decisões de RNF, arquitetura de segurança/desempenho/escalabilidade, ou projetar sistemas com critérios de qualidade mensuráveis.

Use when you need to review, improve, or build Spring Boot 4.0.x applications — including proper usage of @SpringBootApplication, component annotations (@Controller, @Service, @Repository), bean definition and scoping, configuration classes and @ConfigurationProperties (with @Validated), component scanning, conditional configuration and profiles, constructor injection, @Primary and @Qualifier for

Use when you need to implement acceptance tests from a Gherkin .feature file for Spring Boot applications — including finding scenarios tagged @acceptance, implementing happy path tests with TestRestTemplate, @SpringBootTest, Testcontainers with @ServiceConnection for DB/Kafka, and WireMock for external REST stubs. Requires .feature file in context. This should trigger for requests such as Review

Use when you need framework-agnostic WireMock guidance — stub design, JSON or programmatic mappings, precise request matching, response bodies and faults, classpath fixtures, isolation and reset between tests, verification of calls, dynamic ports and base URLs, and avoiding flaky stubs — without choosing Spring Boot, Quarkus, or Micronaut. This should trigger for requests such as Design or review

Use when you need to apply functional exception handling best practices in Java — including replacing exception overuse with Optional and VAVR Either types, designing error type hierarchies using sealed classes and enums, implementing monadic error composition pipelines, establishing functional control flow patterns, and reserving exceptions only for truly exceptional system-level failures. This s

Use when creating a plan using Plan model and enhancing structured design plans in Cursor Plan mode for Java implementations. Use when the user wants to create a plan, design an implementation, structure a development plan, or use plan mode for outside-in TDD, feature implementation, or refactoring work. This should trigger for requests such as Create a plan with Cursor Plan mode; Write a plan wit
