Load Testing Plan Skill

Produce a complete load and performance testing plan for a service — covering test objectives, scenario definitions, tooling configuration, success thresholds, and CI integration. A good load testing plan eliminates ambiguity about what "performance is acceptable" means, so engineers can run tests and get a pass/fail answer without having to interpret raw numbers themselves.

Required Inputs

Ask for these if not already provided:

• Service name and key endpoints — which endpoints are under test (path, method, typical request/response shape)
• Current traffic baseline — current requests/sec, p50/p99 latency, error rate under normal load
• Peak traffic expectations — expected peak RPS (e.g. 10× baseline for flash sales, or seasonality peak)
• SLO targets — latency SLOs (p99 < X ms), error rate SLO (< Y%), availability target
• Preferred testing tool — k6, Locust, JMeter, Gatling, or no preference
• Test environment availability — dedicated load test environment, staging, or production (with traffic shaping)
