Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00011 | $0.02496 |
| Opus 5.5 | $0.00004 | $0.00998 |
| Sonnet 5.5 | $0.00002 | $0.00499 |
| Haiku 4.5 | $0.00001 | $0.00250 |
Grade A, and why
node-kernel-nft 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-nft
Synopsis
/openshift:node-kernel-nft <node> <image> --command <cmd> [--family <family>]
Description
The openshift:node-kernel-nft command allows interaction with the kernel to list packet filtering and classification rules managed by nftables. Nftables is the modern successor to iptables, providing a more unified and efficient packet filtering framework in the Linux kernel.
In OVN-Kubernetes environments, nftables may be used for:
- Modern packet filtering replacing legacy iptables
- Service load balancing rules
- Network policy enforcement
- NAT rules for ingress and egress traffic
- More efficient rule matching than iptables
The command uses oc debug to create an ephemeral container with host network access, then executes nft operations. The image must contain the nft CLI utility.
Implementation
This command invokes the openshift-node-kernel skill which provides kernel-level nftables inspection capabilities:
- Parameter Validation: Validates required node, image, and command parameters
- Utility Check: Verifies the debug image contains the
nftutility - Command Execution: Uses
oc debugto create ephemeral container and execute nft commands - Output Filtering: Removes common oc debug warnings to provide clean output

Parameters
Required Parameters
-
node: Name of the Kubernetes node where nftables configuration should be extracted.
- Must be a valid node name in the cluster

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.

node-kernel-nft is a command published in the GitHub repository wangke19/gemini-ai-helpers (2 stars, last pushed 7mo ago), licensed Apache-2.0. It adds 11 tokens to every session and 2,496 once invoked, about $0.0000 per session on Opus 5.5. 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 2026-09-03.
