Assess EKS cluster upgrade readiness by running automated checks across.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# EKS Upgrade Readiness Skill ## Overview This skill assesses a live EKS cluster's readiness for a Kubernetes version upgrade. It connects to the cluster via AWS APIs, 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?" All operations are **read-only** — this skill does not modify your cluster. ## What Gets Assessed | # | Section | Key Checks | |---|---------|------------| | 01 | Version Validation | Upgrade path validity, version skew policy, support status & cost | | 02 | Breaking Changes | Version-specific API removals, behavioral changes, resource impact | | 03 | Deprecated API Detection | Live scan of cluster resources for deprecated/removed APIs | | 04 | Add-on Compatibility | Core add-on versions, OSS add-on matrix, Karpenter compatibility | | 05 | Node Readiness | Node version skew, AL2→AL2023 migration, AMI compatibility | …

How to install
mdr add aws-samples/sample-apex-skills/eks-upgrade-check@sha256:41911e8b6dbade33The line at the top of this page pins the label git:20261108.4542c5b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
