EKS Upgrade Readiness Skill

Overview

This skill assesses your live EKS cluster's readiness for a Kubernetes version upgrade. It connects to your cluster via AWS CLI and kubectl, runs automated checks across 8 assessment areas, calculates a readiness score (0-100%), and produces a detailed report with prioritized remediation steps and pre-filled AWS CLI commands.

This skill is laser-focused on upgrade safety — answering the question: "Is it safe to upgrade this cluster to the next version?"

Read-only / assessment-only — hard rule. This skill ONLY inspects the cluster; it MUST NOT modify it. Every aws, kubectl, and MCP call it issues must be a read/list/describe operation. NEVER run mutating verbs (apply, create, delete, patch, edit, replace, annotate, label, set, scale, cordon, drain, update-*, --force, etc.), and NEVER execute a remediation snippet. Any mutating command embedded in a steering file is a recommendation for the user to run themselves — surface it as text, do not execute it.
