k8s-troubleshoot

k8s-troubleshoot is a skill for Claude Code, Codex from rohitg00/kubectl-mcp-server. It costs 41 tokens per session (1,459 once invoked), scanned A, original, MIT.

A guide for diagnosing Kubernetes, a system for running containerised applications. It covers checking pods, nodes, workloads, logs, events, resources, endpoints, and network policies.

In plain words
What is it for?
Use it to investigate pod failures such as CrashLoopBackOff or ImagePullBackOff, resource problems, unhealthy nodes, missing endpoints, and network-policy issues.
Why use it?
It gives a structured way to find why an application is failing, restarting, stuck, unreachable, or running on an unhealthy machine.

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

k8s-troubleshoot 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 12d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/diagnose-pod.py, scripts/health-check.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Kubernetes Troubleshooting

Expert debugging and diagnostics for Kubernetes clusters using kubectl-mcp-server tools.

When to Apply

Use this skill when:

  • User mentions: "debug", "troubleshoot", "diagnose", "failing", "crash", "not starting", "broken"
  • Pod states: Pending, CrashLoopBackOff, ImagePullBackOff, OOMKilled, Error, Unknown
  • Node issues: NotReady, MemoryPressure, DiskPressure, NetworkUnavailable, PIDPressure
  • Keywords: "logs", "events", "describe", "why isn't working", "stuck", "not responding"

Priority Rules

Priority Rule Impact Tools
1 Check pod status first CRITICAL get_pods, describe_pod
2 View recent events CRITICAL get_events
3 Inspect logs (including previous) HIGH get_pod_logs
4 Check resource metrics HIGH get_pod_metrics
5 Verify endpoints MEDIUM get_endpoints
6 Review network policies MEDIUM get_network_policies
7 Examine node status LOW get_nodes, describe_node

Quick Reference

Symptom First Tool Next Steps
Pod Pending describe_pod Check events, node capacity, resource requests
CrashLoopBackOff get_pod_logs(previous=True) Check exit code, resources, liveness probes
ImagePullBackOff describe_pod Verify image name, registry auth, network
OOMKilled get_pod_metrics Increase memory limits, check for memory leaks
ContainerCreating describe_pod Check PVC binding, secrets, configmaps
Terminating (stuck) describe_pod Check finalizers, PDBs, preStop hooks

Diagnostic Workflows

Pod Not Starting

1. get_pods(namespace, label_selector) - Get pod status
2. describe_pod(name, namespace) - See events and conditions
3. get_events(namespace, field_selector="involvedObject.name=<pod>") - Check events
4. get_pod_logs(name, namespace, previous=True) - For crash loops

Common Pod States

State Likely Cause Tools to Use
Pending Scheduling issues describe_pod, get_nodes, get_events
ImagePullBackOff Registry/auth describe_pod, check image name
CrashLoopBackOff App crash get_pod_logs(previous=True)
OOMKilled Memory limit get_pod_metrics, adjust limits
ContainerCreating Volume/network describe_pod, get_pvc

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
