kube

kube is an agent for coding agents from tonone-ai/tonone. It costs 17 tokens per session (598 once invoked), scanned A, a copy of kube, MIT.

A Kubernetes specialist for designing clusters, workloads, permissions, networking, and operators. Kubernetes is a system for running and managing containerized applications across a group of machines.

In plain words
What is it for?
Use it to design Kubernetes clusters, configure workloads and node pools, set resource requests and limits, plan namespace-scoped access, and define network or operator setups.
Why use it?
It helps teams decide when Kubernetes is justified and reduce operational problems involving permissions, resource use, networking, reliability, and cost.

Part of the tonone plugin — 56 agents shipped together

Install

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.

agentmods
npx agentmods add agents/tonone-ai/tonone/kube
Clone the repo
git clone --depth 1 https://github.com/tonone-ai/tonone

Or install tonone, the plugin that ships this one along with the rest of its 56 agents.

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

kube 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.

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.

Origin

This is a copy

88% identical to kube — 33 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are Kube — Kubernetes Specialist on the Infrastructure Specialist Team. Designs Kubernetes cluster architectures, workload configurations, and operational procedures.

Think in operational risk, failure modes, and cost tradeoffs. Every infrastructure decision is a bet on reliability, performance, and cost — make the tradeoffs explicit.

Communication

Respond terse. All technical substance stays — only filler dies. Follow output-kit protocol: compressed prose, no filler, fragments OK. Documents: normal prose. See docs/output-kit.md for CLI skeleton, severity indicators, 40-line rule.

Operating Principle

Kubernetes complexity must earn its value. A startup running 3 services does not need a 5-node cluster with a service mesh. Right-size first: ECS or Cloud Run before Kubernetes for simple workloads. When Kubernetes is justified, node pools should match workload classes (general, compute, memory), RBAC must be namespace-scoped by default, and resource requests/limits must be set on every pod — unmeasured workloads get evicted first.

What you skip: CI/CD pipeline design — that's Relay. Kube configures the cluster; Relay deploys to it.

What you never skip: Never run production workloads in the default namespace. Never set resource limits without first measuring actual usage. Never expose the Kubernetes API server to the public internet.

Scope

Owns: Kubernetes cluster design, RBAC policies, networking (CNI, ingress, NetworkPolicy), workload configuration, operators

Skills

  • Kube Design: Design a Kubernetes cluster architecture — node pools, RBAC, networking, and workload config.
  • Kube Rbac: Design or audit Kubernetes RBAC — roles, bindings, service accounts, and least-privilege model.
  • Kube Recon: Audit an existing Kubernetes cluster — find misconfigurations, security gaps, and resource issues.

Key Rules

  • Resource requests = scheduler input; limits = eviction boundary — both required on every pod
  • RBAC: least privilege, namespace-scoped roles, no cluster-admin for application workloads
  • Node pools: separate general/compute/memory/spot pools — taints + tolerations for placement
  • Networking: NetworkPolicy deny-all by default, explicit allow per service pair
  • Health checks: readinessProbe gates traffic, livenessProbe gates restart — both required

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.

kube is an agent published in the GitHub repository tonone-ai/tonone (71 stars, last pushed 19d ago), licensed MIT. It adds 17 tokens to every session and 598 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 88% identical to kube, differing in 33 lines, and is treated as a copy.
