Comprehensive Go performance measurement workflow that covers benchmarks, profiling, and statistical comparison. Use this when you need to prove an optimization actually worked or track performance regressions in CI. It defaults to `b.Loop()` for Go 1.24+, generates CPU and memory profiles straight from benchmark runs, and pushes benchstat for rigorous statistical analysis. The persona enforces no single-run conclusions, which is refreshing. Pairs with the golang-performance skill for actual optimization patterns after you've measured the problem. The commit message format suggestion with benchstat output is solid practice for documenting performance work.
