volcano-diagnose-pod

volcano-diagnose-pod is a skill for Claude Code, Codex from scitix/siclaw. It costs 32 tokens per session (1,931 once invoked), scanned A, original, Apache-2.0.

A diagnostic tool for pods managed by Volcano, a Kubernetes scheduler for workloads that may need resources together. It examines the pod, its scheduling group, events, and resource queue.

In plain words
What is it for?
It helps investigate unscheduled pods, scheduling events, PodGroups, queue settings, and, when requested, node resources. It does not modify pods or scheduling settings.
Why use it?
It connects scheduling errors with the relevant pod, queue, and cluster events so the cause of a pending pod is easier to identify.

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

volcano-diagnose-pod 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 10d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/diagnose-pod.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.

Volcano Pod Diagnosis

Diagnose Volcano-managed Pod scheduling issues. This skill checks Pod status, associated PodGroup, scheduling events, and Queue configuration to identify why a Pod cannot be scheduled.

Scope: This skill is for diagnosis only. Once you identify the root cause, report it to the user and stop. Do NOT attempt to modify pod specs, PodGroups, or Queues — that should be left to the user.

Usage

bash skills/core/volcano-diagnose-pod/scripts/diagnose-pod.sh --pod <pod-name> --namespace <namespace>

Parameters

Parameter Required Description
--pod POD yes Pod name to diagnose
--namespace NS no Namespace (default: default)
--verbose no Show detailed output including node resources

Examples

Diagnose a pending pod in default namespace:

bash skills/core/volcano-diagnose-pod/scripts/diagnose-pod.sh --pod my-job-0

Diagnose a pod in specific namespace:

bash skills/core/volcano-diagnose-pod/scripts/diagnose-pod.sh --pod my-job-0 --namespace training

Verbose mode with node resource information:

bash skills/core/volcano-diagnose-pod/scripts/diagnose-pod.sh --pod my-job-0 --namespace training --verbose

Diagnostic Flow

The script performs the following checks in order:

1. Pod Status

Check the Pod's current phase and conditions.

kubectl get pod <pod> -n <ns> -o wide
kubectl describe pod <pod> -n <ns>

2. PodGroup Status

Check if the Pod is associated with a PodGroup and its scheduling status.

kubectl get pod <pod> -n <ns> -o jsonpath='{.metadata.annotations.scheduling.volcano.sh/pod-group}'
kubectl get podgroup <podgroup> -n <ns>

Key fields to check:

  • spec.minMember: Minimum members required for Gang scheduling
  • status.phase: Pending, Inqueue, Running, Unknown
  • status.running: Number of running pods
  • status.pending: Number of pending pods

3. Events Analysis

Check scheduling events for failure reasons.

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.
