kubernetes-platform

kubernetes-platform is a skill for Claude Code from pwdev-solucoes/pwdev-claude-marketplace. It costs 99 tokens per session (779 once invoked), scanned A, original, Apache-2.0.

A guide to diagnosing and operating Kubernetes, a system that runs containerized applications across a cluster of machines. It covers workloads, networking, storage, scaling, secrets, Helm, Argo CD, and certificates.

In plain words
What is it for?
Use it to investigate crashing or pending pods, image-pull failures, ingress errors, storage problems, autoscaling issues, deployments, and Helm or Argo CD setups.
Why use it?
It helps trace common failures through logs, events, resource limits, network targets, storage configuration, and health checks before making a change. It also requires confirming the active cluster context so production is not changed by mistake.

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

kubernetes-platform scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Kubernetes Platform

Você diagnostica cluster. Lê muito antes de mudar qualquer coisa.

Portão de segurança

${CLAUDE_PLUGIN_ROOT}/references/execucao-segura.md.

Confirme o contexto antes de tudo:

kubectl config current-context

Compare com a seção 2 do contexto. Não bateu ou não está mapeado: trate como produção e pergunte.

Diagnóstico por sintoma

Sintoma Ordem de verificação
CrashLoopBackOff logs --previousdescribe (exit code) → probe → recurso
ImagePullBackOff nome da imagem → tag existe → imagePullSecret → registry
Pending describe (events) → recurso do node → taint/toleration → PVC
OOMKilled limit de memória → uso real → vazamento na app
Ingress 502 endpoints do service → selector bate com label? → porta → app viva
PVC Pending StorageClass existe → provisioner → zona do node
HPA não escala metrics-server → requests definidos → limite máximo

describe mostra events — é onde a resposta costuma estar, e é o que mais se esquece de olhar.

Leitura

kubectl get pods -n ns -o wide
kubectl describe pod POD -n ns
kubectl logs POD -n ns --previous --tail=200
kubectl get events -n ns --sort-by=.lastTimestamp
kubectl top pods -n ns
kubectl get endpoints SVC -n ns      # selector errado aparece aqui

Mutação — sempre com portão

kubectl scale deploy/X --replicas=N     # confirmar
kubectl rollout restart deploy/X        # confirmar
kubectl apply -f arquivo.yaml           # confirmar; mostrar o diff antes
kubectl delete ...                      # destrutivo; reforçado

Antes de apply, mostre kubectl diff -f — aplicar sem ver o diff é como mudança não intencional entra em produção.

Segredos

kubectl get secret -o yaml expõe base64. Use describe, ou decodifique apenas o campo pedido — e não ecoe o valor.

Anti-padrões

  • Deployment sem resources.requests — quebra HPA e scheduling
  • Sem readiness probe — recebe tráfego antes de estar pronto
  • latest como tag — rollback impossível
  • replicas: 1 em produção
  • Secret em ConfigMap
  • NetworkPolicy ausente em cluster multi-tenant

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
