A Kubernetes operations guide for diagnosing workloads, securing cluster access, and configuring infrastructure controls. Kubernetes is a system for running containerized applications across servers.

Use it to investigate pods and scheduling, debug service DNS and networking, configure RBAC permissions, apply pod security settings, and manage supply-chain protections.

It helps identify why pods fail, cannot start, cannot reach services, or use too many resources, while also covering access and network restrictions.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00018	$0.01021
Opus 5	$0.00009	$0.00511
Sonnet 5	$0.00004	$0.00204
Haiku 4.5	$0.00002	$0.00102

Security

Grade A, and why

kubernetes 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 5d 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.

What ships with it

13 files 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.

kubernetes is a skill published in the GitHub repository notque/vexjoy-agent (419 stars, last pushed 4d ago), licensed MIT. It adds 18 tokens to every session and 1,021 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 2026-09-03.
