This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
cluster-upgrade from nitinjain999/platform-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Plan, run and roll back a Kubernetes minor-version upgrade, EKS first. Finds removed APIs in Git, rendered Helm charts and the live cluster with pluto and EKS upgrade insights, checks add-on compatibility (VPC CNI, CoreDNS, kube-proxy, Karpenter, Flux, KEDA, admission webhooks) against the target version, finds PodDisruptionBudgets that block node drains, plans the node rotation per pool, and picks the right rollback, including EKS one-step version rollback within 7 days or a blue/green cluster.
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
Upgrade a cluster one minor version without an outage, and know before starting how each step is undone. Read `references/cluster-upgrade.md` before responding. It holds the scan commands for each place removed APIs hide, the add-on checks, the drain-blocker query, node rotation per pool type, the EKS rollback rules (one minor version, 7 days, in-place upgrades only) and blue/green as the fallback. **This skill is interactive by default.** With no arguments, ask for the cluster platform (EKS, AKS, GKE, other), the current and target versions, how nodes are provisioned (managed node groups, Karpenter, self-managed, Auto Mode, Fargate) and how workloads are delivered (Flux, Argo CD, Helm, kubectl), then run `plan`. Never run `update-cluster-version`, `update-nodegroup-version` or a drain yourself: produce the commands, the checks and the rollback, and let the user run them. ## Mode dispatch | Mode | What it does | Mutates anything? | |---|---|---| | `plan` | Full phased plan: scans, add-on order, drain blockers, control plane, node rotation, rollback per phase | No | …

How to install
mdr add nitinjain999/platform-skills/cluster-upgrade@sha256:75cb9ad73997a399The line at the top of this page pins the label git:20261018.90b97a9, 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.
