fleet-upgrade-verification from gke-labs/kube-agents is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Reports every GKE cluster's control-plane and node-pool versions against a target version or each cluster's release-channel default, naming the members that lag and by how many minors, and answers whether one cluster is current for its channel (--cluster); run again during a rollout, it shows which members started, completed or stalled since the previous run; with --readiness, it also grades each member on what would stop the upgrade, naming drain-blocking PodDisruptionBudgets, fail-closed…
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
# Fleet upgrade verification Answer "against version X, which clusters lag, by how much, and is it the control plane or a node pool" with a table read from the fleet, not from memory, and "which manifests in our GitOps repositories declare an API that version X removes" with a scan read from Git. Use it when a user asks whether an upgrade has reached every cluster, which members are behind a target, how far the fleet is from a release-channel default, whether one cluster's control plane is current for its channel (`--cluster <location>/<name>`), or whether the repositories are ready for a target version. Run the version report again during a rollout and it also says, per member, what changed since the previous run and which members have stopped moving (see "Track a rollout across runs" and `references/track-a-rollout.md`). With `--readiness` it also says, per member, what would stop the upgrade: a PodDisruptionBudget that blocks every node drain, a fail-closed admission webhook with an unreachable backend in the upgrade's path or able to refuse the control plane's bootstrap RBAC writes (ClusterRoles and …

How to install
mdr add gke-labs/kube-agents/fleet-upgrade-verification@sha256:25dfa2ec029f3f29The line at the top of this page pins the label git:20261104.a2c9ad5, 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.
