Kubernetes Failure-Mode Workflow (KubeShark)

A structured Kubernetes skill that diagnoses manifests, Helm charts and Kustomize overlays through six failure modes and enforces validation plus rollback planning.

Dev & CodingIntermediate★ 366⑂ 64AI score 8/10Last updated: Aug 2, 2026

What it does

  • Forces capture of execution context first: cluster version, distribution (EKS/GKE/AKS/OpenShift/k3s), namespace criticality, workload type, policy enforcement, CNI, add-ons.
  • Classifies the task into six failure modes: insecure workload defaults, resource starvation, network exposure, privilege sprawl, fragile rollouts, API drift.
  • Loads only the relevant reference files, including conditional platform packs (EKS/IRSA, GKE Autopilot, AKS Entra Workload ID, OpenShift SCC, Argo CD/Flux, Prometheus Operator).
  • Produces real artifacts: hardened manifests, NetworkPolicies, RBAC, PodDisruptionBudgets, Kyverno/OPA rules.
  • Always attaches a validation plan (kubectl diff, --dry-run=server, kubeconform, policy scan) and rollback notes, and refuses blind production applies.

Who it's for

  • Backend and platform engineers writing or reviewing Kubernetes YAML regularly
  • DevOps teams shipping Helm charts or Kustomize overlays to production
  • SREs operating GitOps controllers and observability stacks
  • Anyone tired of AI-generated manifests with wrong apiVersions or missing security context

Example uses

  1. "Review this Deployment for production readiness" → flags missing securityContext, mutable image tags and absent probes per failure mode, returns a fixed manifest plus dry-run commands.
  2. "Generate a manifest for a workload that reads from S3 on EKS" → pulls the EKS conditional reference (IRSA / Pod Identity) and emits an annotated ServiceAccount with least-privilege RBAC.
  3. "Audit our manifests before upgrading from 1.25 to 1.30" → API-drift pass on deprecated apiVersions with a kubeconform validation and rollback plan.

  1. Download the ZIP with the button below.
  2. In Claude, open Settings → Capabilities and turn on 'Code execution and file creation'. (one time)
  3. Go to Customize → Skills → + → 'Upload a skill' and upload the ZIP.

Install in Claude Code

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the SKILL.m folder from the GitHub repo LukasNiessen/kubernetes-skill into my ~/.claude/skills/kubernetes-skill/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/LukasNiessen/kubernetes-skill.git ~/.claude/skills/kubernetes-skill

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal and make sure the skills directory exists: mkdir -p ~/.claude/skills
  2. Clone the repository into it: git clone https://github.com/LukasNiessen/kubernetes-skill.git ~/.claude/skills/kubernetes-skill
  3. Confirm both SKILL.md and the references/ folder came along: ls ~/.claude/skills/kubernetes-skill
  4. Restart Claude Code so the skill is registered.
  5. Install kubectl (and optionally kubeconform) locally so the suggested validation commands actually run.
  6. Ask something like "review this Kubernetes manifest for failure modes" and the skill triggers automatically.
