volcano-queue-diagnose

volcano-queue-diagnose is a skill for Claude Code, Codex from scitix/siclaw. It costs 36 tokens per session (2,358 once invoked), scanned A, original, Apache-2.0.

A diagnostic guide for Volcano Queue, a Kubernetes scheduler feature that distributes computing resources among workload queues. It checks queue weights, expected resources, assigned resources, and scheduling delays.

In plain words
What is it for?
Use it to inspect all Volcano queues or one named queue, view their related pods, and examine detailed resource allocation when jobs remain pending.
Why use it?
It helps explain why workloads are waiting when a queue does not have enough resources or scheduling priority. It is for finding the cause only; it does not change queue settings.

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-queue-diagnose 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 4d ago.

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

Diagnose Volcano Queue status, resource allocation, and scheduling bottlenecks. This skill helps understand how resources are distributed across queues and why workloads may be pending due to queue constraints.

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 queue configurations or delete queues.

Not applicable to native ResourceQuota: Volcano Queue and Kubernetes ResourceQuota are independent mechanisms. If the cluster does not use Volcano, use quota-debug instead. To check: kubectl get queue 2>/dev/null — if it returns an error or empty, Volcano is not installed.

Usage

bash skills/core/volcano-queue-diagnose/scripts/diagnose-queue.sh [options]

Parameters

Parameter Required Description
--queue QUEUE no Queue name to diagnose (default: all queues)
--show-pods no Show pods associated with each queue
--verbose no Show detailed resource breakdown

Examples

Diagnose all queues:

bash skills/core/volcano-queue-diagnose/scripts/diagnose-queue.sh

Diagnose specific queue:

bash skills/core/volcano-queue-diagnose/scripts/diagnose-queue.sh --queue training-queue

Show verbose output with pod information:

bash skills/core/volcano-queue-diagnose/scripts/diagnose-queue.sh --queue training-queue --show-pods --verbose

Understanding Volcano Queues

Queue Concept

In Volcano, a Queue is a cluster-level resource allocation unit. Jobs and PodGroups are submitted to queues, and the scheduler distributes resources among queues based on:

  1. Weight - Relative share of cluster resources (proportional: weight 10 vs weight 2 = 83% vs 17%)
  2. Capability - Maximum resources a queue can use (ceiling, not guarantee — actual allocation depends on cluster capacity and competition)
  3. Parent - Hierarchical queue relationships (if enabled)

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.
