kustomize

kustomize is a command for Claude Code from kubestellar/kubestellar-mcp. It costs 0 tokens per session (348 once invoked), scanned A, original, Apache-2.0.

A command for Kustomize, a Kubernetes tool that combines shared configuration with environment-specific overlays to create deployment files. It can target one or more clusters.

In plain words
What is it for?
Building rendered Kubernetes manifests, previewing changes, applying them to selected or all clusters, and deleting resources from an overlay.
Why use it?
It avoids manually editing separate Kubernetes files for each environment and shows whether applying or deleting resources succeeded on each cluster.

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

kustomize 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 7d 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 it actually says

Kustomize

Apply kustomize configurations to multiple clusters.

Usage

Build and apply kustomize overlays to one or more clusters.

Examples

  • "Apply kustomize from ./overlays/production to all clusters"
  • "Build kustomize output from ./base"
  • "Delete resources defined in ./overlays/staging kustomize"

What it does

  1. Builds kustomize output from the specified path
  2. Applies (or deletes) the rendered manifests to target clusters
  3. Reports success/failure per cluster

MCP Tools Used

  • kustomize_build - Render kustomize output without applying
  • kustomize_apply - Build and apply to clusters
  • kustomize_delete - Build and delete those resources

Implementation

Use the kustomize_apply tool with:

  • path: Path to directory containing kustomization.yaml (required)
  • dry_run: Preview without applying
  • clusters: Target clusters (all if not specified)

Examples of Tool Calls

Build only:

{
  "path": "./overlays/production"
}

Apply to all clusters:

{
  "path": "./overlays/production",
  "dry_run": false
}

Delete from specific clusters:

{
  "path": "./overlays/staging",
  "clusters": ["staging-1", "staging-2"]
}

Prerequisites

Requires either:

  • kustomize CLI installed
  • Or kubectl with kustomize support (kubectl kustomize)
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.
