What is gke-workload-security?

A security guide for applications running in Google Kubernetes Engine, Google's managed Kubernetes service. It covers cluster checks, workload identities, network rules, and node protections.

Use it to audit GKE clusters, configure Kubernetes-to-Google Cloud identities, enforce network policies, and check node security settings.

It helps find and fix missing security controls that could allow unauthorized access or unsafe communication between workloads.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00181	$0.01776
Opus 5.5	$0.00072	$0.00710

Security

Grade A, and why

gke-workload-security 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.

Origin

This is a copy

GKE Workload Security

This skill provides workflows and best practices for securing GKE workloads. It covers security auditing, Identity and Access Management (Workload Identity), Network Security (Network Policies), and Node Security.

Workflows

1. Security Audit

Assess the current security posture of your cluster using the provided audit script.

Prerequisites:

gcloud CLI authenticated.
jq command-line JSON processor installed.

Capabilities:

Checks for Workload Identity.
Verifies Network Policy is enabled.
Checks if Shielded Nodes are enabled.
Checks if Binary Authorization is enabled.
Checks for Private Cluster configuration.

Command:

scripts/audit_cluster.sh <cluster-name> <region> <project-id>

2. Configure Workload Identity

Workload Identity allows Kubernetes Service Accounts (KSAs) to impersonate Google Service Accounts (GSAs). This is the recommended method for workloads to access Google Cloud APIs.

Steps:

Create Namespace and KSA:

kubectl create namespace workload-identity-test-ns
kubectl create serviceaccount <ksa-name> \
    --namespace workload-identity-test-ns

Bind KSA to GSA:

gcloud iam service-accounts add-iam-policy-binding <gsa-name>@<project-id>.iam.gserviceaccount.com \
    --role roles/iam.workloadIdentityUser \
    --member "serviceAccount:<project-id>.svc.id.goog[workload-identity-test-ns/<ksa-name>]"

Annotate KSA:

kubectl annotate serviceaccount <ksa-name> \
    --namespace workload-identity-test-ns \
    iam.gke.io/gcp-service-account=<gsa-name>@<project-id>.iam.gserviceaccount.com

Verify Example Pod: Use existing asset assets/workload-identity-pod.yaml to test the configuration. Update the <ksa-name> in the file first.
```
kubectl apply -f assets/workload-identity-pod.yaml -n workload-identity-test-ns
```

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
