How does this skill improve code organization?

It guides the AI to organize code by feature rather than layer and enforces Command-Query Separation to ensure clear, predictable method behavior.

Is this skill part of a larger framework?

Yes, it is part of the Plan Marshall orchestration layer, which aims to provide more predictable and reliable outputs for AI coding assistants.

What Java versions are supported by this skill?

This skill is specifically designed for Java 17 and newer projects, focusing on modern features like records and pattern matching.

What are 'Parameter Objects' in the context of this skill?

The skill enforces the use of Java Records to group related parameters whenever a method requires three or more inputs, improving code clarity.

Can this skill help with performance tuning?

Yes, it includes a dedicated set of standards for Java performance patterns, specifically for optimizing high-performance components.
