Which programming languages are specifically supported?

While the methodology is universal, the skill provides specific profiling tools and code patterns for TypeScript, Bun, and Rust.

Does this skill help with database-related slowdowns?

Yes, it includes optimization patterns for SQL query tuning, indexing, N+1 query resolution, and connection management.

What is the core philosophy of the Performance Engineering skill?

The skill follows the 'Iron Law': No optimization without measurement. It requires establishing a baseline, profiling to find actual bottlenecks, and validating gains with realistic workloads.

What performance metrics does this skill help track?

It helps monitor Latency (P50, P95, P99), Throughput (RPS, ops/sec), Memory usage (Heap, GC frequency), and CPU utilization (hot paths, time complexity).

Optimizes code performance through a rigorous cycle of measurement, profiling, and targeted optimization to eliminate bottlenecks.

The Performance Engineering skill provides a systematic framework for Claude to profile code, identify actual bottlenecks, and implement evidence-based optimizations across TypeScript, Bun, and Rust environments. It follows the 'Iron Law' of no optimization without measurement, ensuring that performance gains are validated against realistic workloads while monitoring latency (P95/P99), throughput, and resource utilization. This skill prevents premature optimization by forcing a data-driven workflow: establishing baselines, profiling hot paths, and validating improvements through statistical measurement.
