SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill eliminates inconsistency in Java codebases by enforcing modern language standards, concurrency models, and architectural patterns, ensuring high-quality, maintainable, and performant code.

Core Features & Use Cases

  • Modern Language Standards: Enforces the use of records, sealed types, and pattern matching while discouraging legacy patterns like Lombok.
  • Concurrency Management: Mandates virtual threads for I/O-bound tasks to maximize throughput without the complexity of reactive programming.
  • Architectural Guardrails: Provides clear conventions for exception handling, null safety, and package-by-feature organization to prevent technical debt.

Quick Start

Apply the java skill conventions to review the current module for compliance with virtual thread usage and record-based data modeling.

FAQPage Schema
How do I enforce Java 21 virtual threads for concurrency instead of reactive programming?▼

Standardize Java 21 development by mandating virtual threads for I/O-bound tasks, maximizing throughput without reactive complexity. This skill enforces modern concurrency models during code review and architectural design.

What is the best way to standardize Java architecture and code review for records and sealed types?▼

Standardize Java architecture by enforcing records, sealed types, and pattern matching while discouraging legacy patterns like Lombok. This skill provides guardrails for package-by-feature organization and null safety.

Does this Java standardization approach work with Gradle and Spotless formatting?▼

Yes, standardizing Java 21 development requires adherence to Gradle-based build conventions, Spotless formatting, and static analysis via Error Prone and NullAway to ensure maintainable code.

How do I apply robust exception handling and null safety conventions to a Java codebase?▼

Apply robust exception handling and null safety by enforcing architectural guardrails during implementation and code review. This skill standardizes Java 21 practices to prevent technical debt.

Why should I use virtual threads for I/O-bound tasks in Java 21 instead of traditional thread pools?▼

Virtual threads maximize throughput for I/O-bound tasks without the complexity of reactive programming. This skill standardizes Java 21 concurrency by mandating virtual threads for high performance.
