Does it support standard SLF4J logging?

No, it specifically implements the proprietary CuiLogger framework and LogRecord patterns for structured logging as per CUI standards.

Can this skill help with Maven builds?

Yes, the skill includes a workflow step to verify compliance by executing Maven build and test commands after code changes.

What is the primary focus of this Java skill?

It focuses on enforcing the specific coding standards of the CUI OSS ecosystem, including null safety, Lombok usage, and modern Java syntax.

How does it handle null safety?

It requires @NullMarked at the package level and mandates the use of Optional for return types instead of @Nullable to ensure type-safe code.

Enforces high-quality Java development standards including null safety, Lombok patterns, and modern language features for CUI OSS projects.

This skill provides a comprehensive framework for developing and refactoring Java code according to CUI Open Source Software (OSS) standards. It guides AI assistants through essential practices like strict null safety using JSpecify, optimized Lombok usage for immutability and delegation, and the integration of modern Java features such as Records and switch expressions. By utilizing the specific CUI logging framework and DSL-style constants, it ensures consistency across complex Java codebases while automating the application of best practices like the Single Responsibility Principle and defensive programming.
