volcano-node-resources

A diagnostic tool for checking the computing capacity of nodes in a Volcano cluster. Volcano is a Kubernetes scheduler for workloads that may need groups of resources together.

In plain words
What is it for?
It helps inspect all nodes or selected nodes, filter by labels, and view resource usage or the pods running on them.
Why use it?
It shows whether nodes have enough available CPU, memory, or GPUs, helping explain why workloads may not be scheduled.

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-node-resources 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 3d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/get-node-resources.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 Node Resources

Query cluster node resources to understand capacity and availability for Volcano scheduling. This skill helps identify resource bottlenecks at the node level.

Scope: This skill is for diagnosis only. It retrieves resource information but does not modify any cluster state.

Usage

bash skills/core/volcano-node-resources/scripts/get-node-resources.sh [options]

Parameters

Parameter Required Description
--node NODE no Query specific node only
--label LABEL no Filter nodes by label (e.g., gpu=true)
--show-usage no Show current resource usage (requires metrics-server)
--show-pods no Show pods running on each node
--format FORMAT no Output format: table (default), json, wide

Examples

Get overview of all nodes:

bash skills/core/volcano-node-resources/scripts/get-node-resources.sh

Check specific node:

bash skills/core/volcano-node-resources/scripts/get-node-resources.sh --node worker-1

Check GPU nodes:

bash skills/core/volcano-node-resources/scripts/get-node-resources.sh --label nvidia.com/gpu.present=true

Show resource usage:

bash skills/core/volcano-node-resources/scripts/get-node-resources.sh --show-usage

Show with pod information:

bash skills/core/volcano-node-resources/scripts/get-node-resources.sh --show-pods

JSON output for parsing:

bash skills/core/volcano-node-resources/scripts/get-node-resources.sh --format json

Understanding Node Resources

Resource Types

Resource Description Scheduling Impact
cpu CPU cores (millicores) Primary scheduling constraint
memory RAM (bytes) Primary scheduling constraint
nvidia.com/gpu GPU devices Hardware-specific scheduling
pods Max pods per node Density limit
ephemeral-storage Disk space Secondary constraint

What ships with it

1 file 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.

volcano-node-resources is a skill published in the GitHub repository scitix/siclaw (230 stars, last pushed 4d ago), licensed Apache-2.0. It adds 27 tokens to every session and 2,050 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
