GKE Workload Scaling Troubleshooting Skill

Use this skill to systematically diagnose and resolve HorizontalPodAutoscaler (HPA) failures on GKE — metrics reported as <unknown>, FailedGet* events, missing resource requests, custom/external metrics-pipeline breakage, HPA that refuses to scale up or down, scale-to/from-zero issues, and slow HPA reaction on large clusters. This skill operates non-interactively and enforces a read-only diagnostics boundary before proposing manifest or configuration corrections.

For configuring HPA/VPA objects and scaling best practices, use the gke-workload-scaling skill instead. This skill focuses on failure diagnosis.
