Description
golang-benchmark is an agent skill from the samber cc-skills-golang collection for measuring Go performance: writing benchmarks, running them, profiling hot paths with pprof, and comparing results before and after a change. Its persona is a Go performance measurement engineer who never draws conclusions from a single run and treats statistical rigour and controlled conditions as prerequisites for any optimisation decision. The skill covers the full measurement workflow: write a benchmark, run it, profile the result, compare before and after statistically, and track regressions in continuous integration. It sets out file and naming conventions for benchmarks, such as putting the benchmarks for a source file in a matching benchmark test file. It uses benchstat, installed with go install golang.org/x/perf/cmd/benchstat@latest, to compare runs with statistical significance. The skill points to the golang-performance skill for optimisation patterns to apply after measuring, and to the golang-troubleshooting skill for setting up pprof on a running service. It is useful for developers who want evidence that a change made Go code faster before they commit it, and who want regressions caught in CI. It is listed on skills.sh, where the page shows install counts and GitHub stars for the collection, and its security audits all pass. Install it with npx skills add https://github.com/samber/cc-skills-golang --skill golang-benchmark.…
