k8s-templates

k8s-templates is a skill for Claude Code from Sagart-cactus/claude-k8s-plugin. It costs 22 tokens per session (705 once invoked), scanned A, original, MIT.

Starter files for developing Kubernetes operators: programs that manage applications inside Kubernetes. They include templates for Tilt, a local development tool, Make, a build task tool, and Kustomize, a way to customize Kubernetes configuration.

In plain words
What is it for?
Use them to create a local kind Kubernetes cluster, start a Tilt development loop, deploy a development configuration, check the deployment, and generate operator code and resource definitions.
Why use it?
They provide a repeatable starting structure for running, generating, deploying, and checking an operator during development. This avoids setting up these development tasks from scratch.

Skill for Claude Code

Written for Claude Code: shipped in a Claude Code plugin.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./scripts/setup-kind.sh.

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

k8s-templates 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 11d 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.
