Java Generics Optimizer
Optimizes Java codebases by implementing type-safe generics patterns and PECS principles for robust API design.
This skill provides specialized guidance for reviewing and refactoring Java code to ensure peak generics quality. It focuses on enforcing compile-time type safety by eliminating raw types, applying the PECS (Producer Extends Consumer Super) principle for wildcards, and managing complex scenarios like type erasure and heap pollution. Whether you are upgrading legacy code or designing modern, reusable APIs, this skill integrates advanced patterns with modern Java features like Records and sealed types to streamline enterprise-grade development workflows.
