Does this skill perform 5 Whys analysis?

Yes, the skill is built around a '5 Whys' methodology to ensure the true root cause is identified rather than just addressing surface-level symptoms.

What Kubernetes issues can this skill help diagnose?

It specializes in common pod failures like CrashLoopBackOff and OOMKilled, network connectivity issues, pending PVCs, and stalled Flux or Helm deployments.

How does it handle Flux CD troubleshooting?

It provides diagnostic steps for stalled HelmReleases and walks through the OCI artifact promotion pipeline to identify where a deployment is stuck.

Can it debug network policy issues?

Absolutely; it includes specific procedures for using Hubble to observe dropped traffic and check for missing Cilium network policy or namespace labels.

Can this skill suggest fixes for my cluster?

Yes, while prioritizing a read-only investigation phase, it provides specific remediation recommendations such as Flux suspension/resumption, label updates, or YAML configuration changes.

デプロイメントとDevOps

Automates Kubernetes incident investigation and root cause analysis using site reliability engineering methodologies.

This skill provides a structured framework for diagnosing complex Kubernetes failures, implementing a rigorous '5 Whys' approach to move beyond surface symptoms to actionable root causes. It empowers Claude to correlate data from multiple sources—including kubectl events, container logs, and Prometheus metrics—while providing specialized playbooks for Cilium network policies, Hubble traffic observation, and Flux CD reconciliation stalls. Whether you are dealing with a CrashLoopBackOff, a stuck OCI promotion pipeline, or a mysterious service timeout, this skill ensures a methodical, evidence-based path to remediation.
