debug-k8s

debug-k8s is a skill for Claude Code, Codex from adrielp/ai-engineering-harness. It costs 19 tokens per session (1,181 once invoked), scanned A, original, Apache-2.0.

A read-only method for investigating Kubernetes problems by examining pods, logs, events, and cluster state. Kubernetes is a system for running and managing containerized applications across machines.

In plain words
What is it for?
Use it to inspect pod details and logs, review cluster events, describe resources, and investigate startup, application, networking, or resource issues.
Why use it?
It gathers the operational evidence needed to explain why a workload is not starting or is behaving incorrectly without changing the cluster.

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

debug-k8s 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 5d 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.

Debug Kubernetes

You are tasked with helping debug Kubernetes issues. This command allows you to investigate problems by examining pods, logs, events, and cluster state without making changes.

MCP Server Preference

When the Kubernetes MCP server is available, prefer using MCP tools:

  • mcp__kubernetes__list_pods - List pods in a namespace
  • mcp__kubernetes__get_pod - Get pod details
  • mcp__kubernetes__get_logs - Get pod logs
  • mcp__kubernetes__list_events - List cluster events
  • mcp__kubernetes__describe_resource - Describe any resource

When MCP is unavailable, fall back to kubectl commands via Bash.

To check if MCP is available, attempt an MCP tool first. If it fails with "tool not found", use kubectl.

Initial Response

When invoked WITH a context (namespace, pod name, or resource):

I'll help debug Kubernetes issues with [resource]. Let me check the cluster state.

What specific problem are you encountering?
- Pod not starting?
- Application errors?
- Network/connectivity issues?
- Resource constraints?

I'll investigate the pods, logs, and events to help identify the issue.

When invoked WITHOUT parameters:

I'll help debug your Kubernetes issue.

Please provide some context:
- Which namespace?
- Which pod/deployment/service?
- What's the expected vs actual behavior?

I can investigate pod status, logs, events, and resource state.

Process Steps

Step 1: Understand the Problem

  1. Get context from user (namespace, resource name, symptoms)
  2. Quick cluster check:
    • Current kubectl context
    • Target namespace

Step 2: Investigate the Issue

Spawn parallel Task agents based on the problem type:

Task 1 - Pod Status:
Check pod status and conditions
- List pods in namespace
- Get pod details (phase, conditions, container status)
Return: Pod state summary, restart counts, readiness
Task 2 - Pod Logs:
Examine recent logs for errors
- Get logs from main container
- Check previous container logs if restarted
Return: Key errors/warnings with timestamps

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.
