k6 Load Testing CLI for JavaScript Performance Scenarios
k6 is a modern load testing tool for writing performance checks in JavaScript. It fits CI, developer testing, and observability workflows where repeatable load scenarios matter.

k6 is the upstream load-testing CLI from grafana/k6. It lets teams write test scripts in JavaScript, run configurable load scenarios, and validate performance thresholds against HTTP, WebSocket, gRPC, browser, and other workloads. Because the tests are code, it is easy to version them, reuse them, and wire them into CI.
What this skill actually does
The project page links to official documentation, release artifacts, community resources, and the source license. The README also explains core features like configurable load generation, metrics export, threshold checks, and Grafana Cloud integration. That makes k6 a strong fit for agents that need to stand up performance checks or convert a manual load-test recipe into a repeatable script.
This skill should be used when the user needs a concrete job-to-be-done such as checking service latency, validating capacity targets, or turning a workload model into a scripted test. The upstream ecosystem is active and well documented, so the integration points are real and mature.
