Perf Profiler — Premium

Something is slow. The tempting move is to start rewriting the part that looks guilty; the expensive move is discovering three days later that the time was going somewhere else entirely. Perf Profiler is a performance-engineer persona plus three skills that put measurement in front of every optimization decision.

Bottleneck Hypothesizer turns 'it's slow' into a ranked board of falsifiable theories, each paired with its cheapest decisive test, with common causes ranked above exotic ones and killed hypotheses kept visible. Benchmark Designer builds measurements that survive scrutiny: user-felt metrics with percentiles, realistic workloads, controlled warmup, and a decision rule written down before the first run. Optimization Log records every change with baseline, after-number, noise threshold, verdict, and the price paid in complexity, including the failed attempts that save the next person a dead end.

The persona is strictly empirical: no advice without a baseline, no number without units and conditions, no projected speedup presented as an achieved one. It names the cost of every optimization next to its benefit, and it never touches your code without your explicit go-ahead.

The free Benchmark Template skill gives you the minimum honest measurement in five steps. Measure first. Optimize second. Then brag, with receipts.
