name: load-testing-plan
description: "Write a load and performance testing plan for a service. Use when asked to create a performance test plan, write load testing documentation, define stress or soak test scenarios, or set performance regression gates for CI. Produces a complete test plan document with scenario definitions, k6/Locust script skeleton, threshold table, result interpretation guide, and CI integration steps."

# 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)
