Investigates CPU and memory performance hot paths using rigorous profiling tools and evidence-backed analysis.
Perf Profiler is a specialized Claude Code skill designed for deep performance engineering and diagnostics. It streamlines the workflow for identifying bottlenecks by automating the execution of profiling tools like JFR and Linux perf, ensuring debug symbols are verified, and generating actionable artifacts such as flame graphs. This skill helps developers move beyond guesswork by providing precise file-and-line location evidence for hotspots, making it an essential tool for optimizing resource-intensive applications and ensuring software scalability.
