AWS RDS (Relational Database Service) management using AWS SDK for Java 2.x. Use when creating, modifying, monitoring, or managing Amazon RDS database instances, snapshots, parameter groups, and configurations.
Analyzes legacy COBOL programs and JCL jobs to assist with migration to modern Java applications. Extracts business logic, identifies dependencies, generates migration reports, and creates Java implementation strategies. Use when working with mainframe migration, COBOL analysis, legacy system modernization, JCL workflows, or when users mention COBOL to Java conversion, analyzing .cbl/.CBL/.cob files, working with copybooks, or planning Java service implementations from COBOL programs.
Stack-specific coding rules for long-running Java Spring Boot server applications, covering Spring MVC REST controllers, dependency injection, Jackson JSON, validation, configuration, persistence integration, testing (unit/integration/system), observability, security, and Maven/Gradle project conventions. Use whenever creating, generating, scaffolding, writing, migrating, troubleshooting, or reviewing Spring Boot server code. This skill is architecture-neutral, it can be composed it with BCE, package-by-feature, package-by-layer, SDD4J, or another architecture skill when the project or user specifies an architecture. Not for serverless deployments, one-off Java CLI applications, or non-Spring Jakarta/MicroProfile services.
This skill should be used when the user asks to "draw every frame in JavaScript", "make an animation with no image assets", "animate this in code / on a canvas", "make a hand-drawn style animated video", "turn this into a short animated film", "make an animated explainer drawn in code", "make an animated story / picture book of my photos", or "make a zero-asset animation like the Opus 5.5 ones". Produces a single self-contained HTML file whose frames are computed on an HTML canvas (seekable, deterministic), renders it to MP4, and self-checks the result. Pairs with the soundtrack skill for code-synthesized music. NOT for charts from data (use chart-animation), pure text motion (use kinetic-typography), or 3D/WebGL (use threejs-animation / shader-glsl from webgl-animation-skills).
Alibaba Java Development Manual (Huangshan Edition 1.7.1) - When writing or reviewing Java code, defining coding standards, handling exceptions and logs, writing unit tests, designing database tables and indexes, or planning engineering layers or system architecture, locate the conventions that should be followed for the relevant scenario. The detailed convention text is in the references/ directory.
Add JavaScript behavior to a Bootstrap 6 component. Use when writing a component's TypeScript source, extending BaseComponent, wiring the data API, adding events or config options, or integrating Floating UI or a third-party library.
Comprehensive guidance for Onion Architecture (洋葱架构) — Jeffrey Palermo's onion architecture with domain-centric layered isolation, dependency inversion from outer to inner rings. Covers domain core, application interfaces, infrastructure implementation, and API adapters with full Java/Spring Boot examples. Use when user asks about onion architecture, 洋葱架构, Jeffrey Palermo, concentric architecture, or needs layered domain isolation.
JUnit5 + Mockito 测试框架技能。覆盖 JUnit5 @ExtendWith替代@RunWith、Mockito @Mock/@InjectMocks规则、测试隔离原则(FIRST)、@SpringBootTest何时用何时不用(@WebMvcTest/@DataJpaTest切片测试)、BDDMockito given/willReturn风格、ArgumentCaptor参数捕获、verify行为验证、@ParameterizedTest参数化测试。 当用户编写 Java 单元测试/集成测试、Mock外部依赖时需要此技能。
Build event-driven applications with Azure Event Grid SDK for Java. Use when publishing events, implementing pub/sub patterns, or integrating with Azure services via events.
Guide for upgrading Java projects between major versions (8→11→17→21→25). Use when user says "upgrade Java", "migrate to Java 25", "update Java version", or when modernizing legacy projects.
Use when you need to use Spring Data JDBC with Java records — including entity design with records, repository pattern, immutable updates, aggregate relationships, custom queries, transaction management, and avoiding N+1 problems. This should trigger for requests such as Review Java code for Spring Data JDBC; Apply best practices for Spring Data JDBC in Java code; Model Spring Data JDBC aggregates with Java records; Review Spring Data JDBC repositories and aggregate boundaries; Improve optimistic locking or domain events in Spring Data JDBC. Part of Plinth Toolkit
Write JavaScript (Node.js v22) for Factorial Code processes and modules — the async main() entry point with module.exports = { main }, fcode.context.parameters, fcode.import(), datastore/storage/env helpers, auto-installed dependencies, and return-value formats. Use when creating or editing .js process or module code for Factorial Code (fcode).
