Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Load Testing Patterns Performance validation with k6 for SLO-driven load testing. ## Basic k6 Script Template ```javascript import http from 'k6/http' import { check, sleep } from 'k6' import { Rate, Trend } from 'k6/metrics' // Custom metrics const errorRate = new Rate('errors') const loginDuration = new Trend('login_duration') // Thresholds define pass/fail criteria export const options = { thresholds: { http_req_duration: ['p(95)<500', 'p(99)<1000'], // 95th < 500ms, 99th < 1s http_req_failed: ['rate<0.01'], // Error rate < 1% errors: ['rate<0.05'], // Custom error rate < 5% }, scenarios: { smoke: { executor: 'constant-vus', vus: 5, duration: '1m', } } } export default function () { const res = http.get('https://api.example.com/health') check(res, { 'status is 200': (r) => r.status === 200, 'response time < 500ms': (r) => r.timings.duration < 500, 'body has status': (r) => JSON.parse(r.body).status === 'ok', }) || errorRate.add(1) sleep(1) } ``` ## Load Profiles ```javascript export const options = { scenarios: { // 1. Smoke Test: verify system works under minimal load smoke: { executor: 'constant-vus', vus: 3, duration: '1m', }, // 2. Load Test: normal expected traffic load:

What does the load-testing-patterns skill do?
k6 script templates, load profiles, response time thresholds, SLO validation, and performance testing strategies.
How do I install it?
Run `npx skills add vibeeval/vibecosystem --skill load-testing-patterns --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From vibeeval/vibecosystem, a repository with 521 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
