Test application performance with k6 load/stress/soak/spike scripts and k6 scenarios, Lighthouse CI for Web Vitals, and performance budgets as CI gates. Covers load profiles, custom metrics, bottleneck identification, and Core Web Vitals (LCP, INP, CLS). Use when: "performance test," "load test," "stress test," "soak test," "spike test," "k6," "k6 scenarios," "Lighthouse," "Web Vitals," "Core Web Vitals," "performance budget." Not for: scheduled production probes — use synthetic-monitoring…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<objective> Measure, assert, and protect application performance with budgets enforced in CI, not subjective "feels fast enough" assessments. This skill covers two domains: **load testing** (can the backend handle traffic?) and **web performance** (is the frontend fast for users?). A report that says "LCP is 3.2s" is information; a CI gate that fails the build at 2.5s is accountability. </objective> ## Quick Route | You need to... | Go to | |----------------|-------| | Test backend capacity / throughput / latency under traffic | **k6 Load Testing** → `references/recipes.md` | | Pick a load shape (constant / ramp / spike / soak) | **Load Profiles** table | | Measure frontend speed for real users (LCP, INP, CLS) | **Web Performance** + **Core Web Vitals** | | Gate page perf in CI | **Lighthouse CI** (gate TBT, not INP — see below) | | A budget is breached and you must find why | **Bottleneck Identification** | | Migrate an existing suite from k6 v1 → v2 | **k6 v2 Migration** callout | ## Discovery Questions Check `.agents/qa-project-context.md` first — if it exists, use it and skip questions already answered there. ### What to Measure …

How to install
mdr add petrkindlmann/qa-skills/performance-testing@sha256:3244287efe5d9acfThe line at the top of this page pins the label v2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
