Agent skill
1 skill
READMEOverview ↓

Diff a current performance measurement against a registered baseline from the perf-baselines registry. Works for any measurement type (NCCL BW, MFU, step-time, latency, throughput, per-kernel times, structured heatmaps, nsys-rep profiles). Honors the operator-supplied tolerance, reports per-dimension deltas, and classifies the overall verdict as GREEN / YELLOW / RED. Pairs with perf-baseline-record. Triggers on "diff baseline", "diff against baseline", "perf regression check", "is this regression real", "compare to baseline", "perf-baseline-diff", "regression diff", or any combination of "diff / compare / regression / check" with "baseline / golden / reference / perf-of-record".
