Kubernetes Diagnostics
Analyze cluster health and compare resources using kubectl-mcp-server's diagnostic tools.
When to Apply
Use this skill when:
- User mentions: "metrics", "health check", "compare", "analysis", "capacity"
- Operations: cluster health assessment, environment comparison, resource analysis
- Keywords: "how much", "usage", "difference between", "capacity planning"
Priority Rules
| Priority | Rule | Impact | Tools |
|----------|------|--------|-------|
| 1 | Check metrics-server before using metrics | CRITICAL | get_resource_metrics |
| 2 | Run health check before deployments | HIGH | cluster_health_check |
| 3 | Compare staging vs prod before release | MEDIUM | compare_namespaces |
| 4 | Document baseline metrics | LOW | get_nodes_summary |
Quick Reference

| Pod metrics | get_resource_metrics | get_resource_metrics(namespace) |
| Node summary | get_nodes_summary | get_nodes_summary() |
| Compare envs | compare_namespaces | compare_namespaces(ns1, ns2, type) |
| List CRDs | list_crds | list_crds() |
