Kubernetes Skills

Security checks across malware telemetry and agentic risk

Overview

This skill openly helps manage Kubernetes Cluster API resources, including sensitive and high-impact operations, without evidence of hidden or malicious behavior.

Install this only for agents you trust to help administer Kubernetes Cluster API environments. Before running mutating examples, verify the kubeconfig context, namespace, target cluster, provider account, manifest contents, quota, and cost or availability impact. Do not expose returned kubeconfigs in chat, logs, tickets, or shared outputs unless intentionally authorized.

Missing User Warnings

Medium
Confidence
92% confidence
Finding
The skill includes a ready-to-run cluster creation example that applies Cluster API resources capable of provisioning real infrastructure, but it does not warn that executing it may create cloud resources, modify infrastructure state, and incur cost. In an agent skill context, omission of an explicit confirmation or safety note increases the chance of accidental execution with operational and financial consequences.

Missing User Warnings

Low
Confidence
84% confidence
Finding
The scaling example directly changes MachineDeployment replica counts, which alters cluster capacity and can affect workload placement, autoscaling behavior, quota consumption, and cloud spend. While scaling is a legitimate administrative action, presenting it without an impact warning or confirmation increases the risk of unintended operational changes.

Missing User Warnings

Medium
Confidence
90% confidence
Finding
The kubeconfig retrieval example returns credentials that can grant administrative access to a workload cluster, yet the skill does not label the output as sensitive or warn against exposing, logging, or forwarding it. In an agent environment, this omission raises the risk of credential leakage through transcripts, tool output handling, or downstream sharing.
