k8s-agent

k8s-agent is an agent for Claude Code from alexeyshishin/as-skill. It costs 0 tokens per session (637 once invoked), scanned A, original, MIT.

An execution agent for Kubernetes configuration and deployment files. Kubernetes is software that runs and manages containers; Kustomize combines environment-specific configuration, while ArgoCD deploys changes from Git.

In plain words
What is it for?
Use it to create or update Kubernetes manifests, Kustomize bases and overlays, ArgoCD ApplicationSets, ingress settings, and ExternalSecret configurations.
Why use it?
It keeps Kubernetes changes within defined folders and separates development deployments from production deployments. It also provides a consistent way to preview and validate configuration.

Written for Claude Code: a Claude Code subagent (agents/*.md).

Good fit Use it to create or update Kubernetes manifests, Kustomize bases and overlays, ArgoCD ApplicationSets, ingress settings, and ExternalSecret configurations.

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-agent 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 1mo 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.

Rules

  • Prod — ArgoCD only, never kubectl apply directly
  • Resource limits/requests are mandatory on ALL containers

  • Don't use deprecated API versions
  • latest tag in prod — forbidden
  • PDB for stateful and critical services
  • Labels: app, version, component, app.kubernetes.io/managed-by: kustomize

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.
