k8s-cluster-api

k8s-cluster-api is a skill for Claude Code, Codex from itechmeat/llm-code. It costs 86 tokens per session (2,612 once invoked), scanned B, original, MIT.

A guide to Kubernetes Cluster API, a Kubernetes project for creating and managing Kubernetes clusters through configuration files and command-line tools. Kubernetes is a system for running containerized applications across machines.

In plain words
What is it for?
Use it when provisioning, upgrading, scaling, migrating, backing up, or checking the health of Kubernetes clusters with Cluster API, clusterctl, or ClusterClass.
Why use it?
It helps standardize cluster creation, upgrades, scaling, and deletion across cloud and on-premises environments. It also covers repeatable infrastructure definitions and managing multiple clusters.

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 B, and why

k8s-cluster-api scanned grade B with 2 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 24d 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.

A mod that escalates privileges can change anything on the machine, not only the project.

Kubernetes Cluster API

Kubernetes Cluster API (CAPI) is a Kubernetes sub-project focused on providing declarative APIs and tooling to simplify provisioning, upgrading, and operating multiple Kubernetes clusters.

Overview

Started by SIG Cluster Lifecycle, Cluster API uses Kubernetes-style APIs and patterns to automate cluster lifecycle management. The infrastructure (VMs, networks, load balancers, VPCs) and Kubernetes configuration are defined declaratively, enabling consistent and repeatable cluster deployments across environments.

Why Cluster API?

While kubeadm reduces installation complexity, it doesn't address day-to-day cluster management:

  • How to consistently provision infrastructure across providers and locations?
  • How to automate cluster lifecycle (upgrades, deletion)?
  • How to scale processes to manage any number of clusters?

Cluster API addresses these gaps with declarative, Kubernetes-style APIs that automate cluster creation, configuration, and management.

Goals

  • Manage lifecycle (create, scale, upgrade, destroy) of Kubernetes-conformant clusters via declarative API
  • Work in different environments (on-premises and cloud)
  • Define common operations with swappable implementations
  • Reuse existing ecosystem components (cluster-autoscaler, node-problem-detector)
  • Provide transition path for existing tools to adopt incrementally

Non-Goals

  • Add APIs to Kubernetes core
  • Manage infrastructure unrelated to Kubernetes clusters
  • Force all lifecycle products to use these APIs
  • Manage non-CAPI provisioned clusters
  • Manage single cluster spanning multiple providers
  • Configure machines after create/upgrade

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.

k8s-cluster-api is a skill published in the GitHub repository itechmeat/llm-code (24 stars, last pushed 24d ago), licensed MIT. It adds 86 tokens to every session and 2,612 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it B with 2 findings (asks for root, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
