node-kernel-ip

node-kernel-ip is a command for Claude Code from wangke19/gemini-ai-helpers. It costs 11 tokens per session (3,548 once invoked), scanned A, original, Apache-2.0.

A command that inspects routing tables, network devices, and interfaces on a Kubernetes node using Linux's ip tool.

In plain words
What is it for?
Use it through an OpenShift debug container to inspect overlay interfaces, routes, interface states, and network namespaces.
Why use it?
It exposes node-level network state that can explain connectivity problems between pods, services, and nodes.

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

node-kernel-ip 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 2mo 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.

Name

openshift:node-kernel-ip

Synopsis

/openshift:node-kernel-ip <node> <image> --command <cmd> [--options <opts>] [--filter <params>]

Description

The openshift:node-kernel-ip command allows interaction with the kernel to list routing tables, network devices, and interfaces. The ip utility is the modern Linux networking configuration tool that shows and manipulates routing, network devices, policy routing, and tunnels.

In OVN-Kubernetes environments, the ip command is essential for:

  • Inspecting OVN overlay network interfaces (genev_sys_*, ovn-k8s-mp0, etc.)
  • Viewing routing tables for pod and service traffic
  • Debugging network namespace configurations
  • Analyzing interface states and configurations
  • Troubleshooting connectivity issues between nodes and pods

The command uses oc debug to create an ephemeral container with host network access, then executes ip operations. The image must contain the ip utility (from iproute2 package).

Implementation

This command invokes the openshift-node-kernel skill which provides kernel-level networking inspection capabilities:

  1. Parameter Validation: Validates required node, image, and command parameters
  2. Utility Check: Verifies the debug image contains the ip utility
  3. Command Execution: Uses oc debug to create ephemeral container and execute ip commands
  4. Output Filtering: Removes common oc debug warnings to provide clean output

Skill Reference:

  • Implementation: extensions/openshift/skills/openshift-node-kernel/node-kernel-ip.sh
  • Helper functions: extensions/openshift/skills/openshift-node-kernel/kernel-helper.sh
  • Documentation: extensions/openshift/skills/openshift-node-kernel/SKILL.md

Parameters

Required Parameters

  • node: Name of the Kubernetes node where network information should be extracted.

    • Must be a valid node name in the cluster
    • Example: ovn-control-plane, ovn-worker, worker-0

  • image: Container image to use for creating a debug connection to the node.

    • Must contain ip utility (iproute2 package)
    • Common images:
      • registry.redhat.io/rhel9/support-tools
      • nicolaka/netshoot

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.
