eks-operation-review

eks-operation-review is a skill for Claude Code, Codex from aws/tools-for-devops-agent. It costs 99 tokens per session (4,097 once invoked), scanned A, original, Apache-2.0.

A review procedure for Amazon EKS, Amazon’s managed service for running Kubernetes clusters. Kubernetes is software that runs and coordinates containerised applications.

In plain words
What is it for?
It helps audit cluster configuration, reliability, security, cost, networking, scalability, and readiness for upgrades against AWS best practices.
Why use it?
It checks whether an EKS environment is ready to operate safely and reliably, including its security, cost, networking, scaling, and upgrade concerns.

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

eks-operation-review 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 4d 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.

EKS Operational Review

Conduct a comprehensive operational review of Amazon EKS clusters aligned with the EKS Best Practices Guide.

When to Use

Activate this skill when the user asks to:

  • Review, audit, or assess EKS clusters
  • Check EKS best practices compliance
  • Evaluate EKS security, cost, reliability, networking, or scalability
  • Perform an EKS operational readiness review
  • Investigate EKS cluster health or configuration

Step 1: Identify Target Clusters

Ask the user which EKS clusters to review. Accept:

  • Specific cluster names and regions
  • "all clusters" in specific regions
  • "all clusters in all regions"

Use the EKS topology data available in the Agent Space to identify clusters. Query CloudWatch and AWS APIs to discover clusters:

  • List EKS clusters across the configured account regions
  • For each cluster, collect configuration details

Step 2: Collect Cluster Configuration

Data source priority: If Kubernetes API access is available (via connected MCP servers such as kubernetes-mcp-server, EKS MCP server, or direct K8s API tools), use it FIRST to get live cluster state. K8s API provides the most accurate, real-time data. Fall back to AWS APIs and CloudWatch only for data not available via K8s API.

K8s API tools (use first when available):

  • resources_list / resources_get — list/read any K8s resource by apiVersion and kind
  • pods_list / pods_get / pods_log / pods_top — pod operations
  • nodes_top — node resource usage
  • events_list — K8s events
  • configuration_contexts_list — available cluster contexts

For EACH cluster, gather the following data. Try K8s API first, then AWS API as fallback:

2.1 EKS Cluster Config

AWS API (no K8s equivalent): Kubernetes version, platform version, control plane logging, secrets encryption, endpoint access, authentication mode, access entries, Auto Mode, tags

2.2 Node Groups & Compute

K8s API first:

  • resources_list(apiVersion="v1", kind="Node") — live node list with labels, capacity, allocatable, conditions
  • nodes_top — actual CPU/memory usage per node
  • resources_list(apiVersion="karpenter.sh/v1", kind="NodePool") — Karpenter NodePools
  • resources_get(apiVersion="karpenter.sh/v1", kind="NodePool", name=<name>) — full NodePool spec (consolidation, limits, disruption, requirements)
  • resources_list(apiVersion="karpenter.k8s.aws/v1", kind="EC2NodeClass") — EC2NodeClasses
  • resources_get(apiVersion="karpenter.k8s.aws/v1", kind="EC2NodeClass", name=<name>) — full spec (amiFamily, blockDeviceMappings, metadataOptions, subnets, SGs)

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.

eks-operation-review is a skill published in the GitHub repository aws/tools-for-devops-agent (45 stars, last pushed today), licensed Apache-2.0. It adds 99 tokens to every session and 4,097 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
