This should trigger for requests such as Improve tracing; Apply OpenTelemetry tracing; Add distributed t

Use when you need to refactor Java code based on profiling analysis findings — including reviewing docs/profiling-problem-analysis and docs/profiling-solutions, identifying specific performance bottlenecks, and implementing targeted code changes to address CPU, memory, or threading issues. This should trigger for requests such as Refactor the code with profiling; Apply profiling; Refactor the code

Use when you need to apply data-oriented programming best practices in Java — including separating code (behavior) from data structures using records, designing immutable data with pure transformation functions, keeping data flat and denormalized with ID-based references, starting with generic data structures converting to specific types when needed, ensuring data integrity through pure validation
