Usage Example

{
  kind: 'skill',
  skill: {
    name: 'k6-performance',
    context: {
      action: 'execute-load-test',
      script: 'tests/performance/load.js',
      vus: 100,
      duration: '5m',
      thresholds: {
        'http_req_duration': ['p(95)<500']
      }
    }
  }
}

Configuration

The skill can execute k6 scripts locally or configure cloud execution for distributed load testing.
