Execute performance and load benchmarks against MuleSoft Omni Gateway (formerly Flex Gateway) on Amazon EKS using the harness under this skill's `scripts/` directory. Use when the user wants to provision the benchmark cluster, deploy a specific Flex version, drive load with k6, capture Grafana evidence, retrieve a Markdown report and dashboard PNGs, compare gateway versions, validate rate-limit or client-id-enforcement behavior under load, or tear the environment back down. Covers the full lifecycle: AWS provisioning, image push, deploy, run, report, and teardown.
