maintenance-check-aws-eks is a skill for Claude Code, Codex from abdullahkhawer/devops-skills. It costs 37 tokens per session (1,730 once invoked), scanned A, original, Apache-2.0.

A maintenance checker for AWS EKS, Amazon's managed Kubernetes service. It compares cluster versions with available upgrades and writes a decision file containing Jira-formatted maintenance tickets.

In plain words
What is it for?
Use it to check EKS cluster versions and produce upgrade tickets for the configured AWS profiles, regions, and environments.
Why use it?
It helps identify required upgrades across configured staging and production clusters before maintenance work is planned.

Written for no agent in particular: nothing here depends on one.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is ./maintenance-checks/maintenance-check-aws-eks-<environment>-<YYYY-MM-DD>.md.

Good fit Use it to check EKS cluster versions and produce upgrade tickets for the configured AWS profiles, regions, and environments.

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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

maintenance-check-aws-eks 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 9d 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.

Maintenance Check AWS EKS Skill

Run this skill when asked to check for available upgrades across an AWS EKS Kubernetes cluster for maintenance. It gathers current versions, compares them against latest available versions, and writes a decision file with Jira-formatted tickets for any required maintenance upgrades.

Configuration

Update the table below with your cluster names, AWS profiles, and region before using this skill:

  • AWS region: <your-aws-region> (e.g. us-east-1, eu-west-1)
Environment Cluster Name AWS Profile
Staging / Non-Prod <your-staging-cluster> <your-nonprod-profile>
Production <your-prod-cluster> <your-prod-profile>

If the user does not specify an environment, ask before proceeding.


Step 1 — Check current EKS cluster version

aws eks describe-cluster \
  --name <cluster-name> \
  --profile <profile> \
  --region <your-aws-region> \
  --query "cluster.version" \
  --output text

Record: current cluster version (e.g. 1.29).


Step 2 — Determine latest available EKS version

aws eks describe-addon-versions \
  --profile <profile> \
  --region <your-aws-region> \
  --query "sort_by(addons[?addonName=='vpc-cni'].addonVersions[].compatibilities[].clusterVersion, &@) | [-1]" \
  --output text

Record: latest available EKS version.

Decision point: If current version == latest version, no maintenance upgrade is needed at all — skip Steps 3–4 and proceed to Step 5 with a "no maintenance upgrade required" output.


Step 3 — Check EKS add-on versions

List installed add-ons and their current vs. latest versions compatible with the target cluster version:

# List installed add-ons
aws eks list-addons \
  --cluster-name <cluster-name> \
  --profile <profile> \
  --region <your-aws-region> \
  --output json

# Current version of each add-on
aws eks describe-addon \
  --cluster-name <cluster-name> \
  --addon-name <addon-name> \
  --profile <profile> \
  --region <your-aws-region> \
  --query "addon.addonVersion" \
  --output text

# Latest version compatible with the target cluster version
aws eks describe-addon-versions \
  --addon-name <addon-name> \
  --kubernetes-version <target-version> \
  --profile <profile> \
  --region <your-aws-region> \
  --query "addons[0].addonVersions[0].addonVersion" \
  --output text

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.
