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.
