k6-perf-test-website
Use when the user wants to performance-test, load-test, or stress-test a public website end-to-end with k6. Produces a hybrid (protocol + browser) test suite, SLO-backed thresholds, a load-generator monitor sidecar, and a Grafana-side investigation playbook for backends the user owns. Triggers on "perf test my site", "performance test my site", "load test this URL", "stress test my web app", "I want to load test [URL]", "set up k6 against my website", "write a k6 suite for [site]", "see if my site handles N concurrent users", or "how does my site perform under traffic". Use this skill whenever the user mentions k6, load testing, stress testing, performance testing, or wants to validate a website under traffic — even if they don't explicitly use the word "test" or ask for the specific outputs this skill produces. This skill is for a full multi-test suite across several workflows; for a single browser test — functional OR a browser load test measuring Web Vitals for one journey — use k6-browser-test.

k6-perf-test-website An end-to-end, opinionated workflow for performance-testing any public website with k6. The skill produces: A scaffolded project with one folder per user-described workflow. Functional protocol + browser tests (must pass before load testing). Hybrid load tests (protocol scenario + 1 browser VU) per test type (smoke / average / stress / spike / soak / breakpoint). SLO-backed thresholds with per-endpoint tagging and Web Vitals. A cross-platform load-generator monitor sidecar. Optional Grafana-side investigation when the user owns the backend. A structured Markdown report at the end. Just want one functional browser test from a plain-language journey? This skill builds a full, multi-test performance suite. For a single k6/browser functional (or standalone browser load) test — with selectors discovered by exploring the live site — use the k6-browser-test skill instead. This skill enforces a few opinions you should not silently override: Always elicit workflows first.
