Benchmark Optimization Loop Use this skill to convert "make it 20x faster" or "try 50 recursive optimizations" into a bounded measured loop that can actually improve a system. Required Baseline Do not optimize until these exist: - the operation being optimized; - the correctness gate that must stay green; - the metric: wall time, p95 latency, rows/sec, cost/run, memory, error rate; - the current baseline; - the search budget: max variants, max time, max spend, max data impact. If the user asks for an unrealistic target, keep the ambition but make the loop bounded and measurable. Loop 1. Measu…
