Identifies and resolves software bottlenecks through systematic measurement and empirical optimization workflows.
This skill equips Claude with a rigorous methodology for diagnosing and fixing performance issues across the entire stack. By enforcing a 'Measure, Optimize, Verify' cycle, it helps developers move beyond guesswork to identify actual bottlenecks in Node.js applications, browser environments, and databases. Whether dealing with N+1 queries, memory leaks, or CPU-intensive loops, this skill provides structured guidance on using industry-standard tools like clinic.js, flame graphs, and Chrome DevTools to ensure every optimization is data-driven and measurably effective.
