rancher-upgrade skillA

rancher-upgrade is agent-read markdown (skill) from air-gapped/skills: Plan and sequence COMMUNITY-edition Rancher upgrades across air-gapped multi-cluster fleets — a management/"hosting" Rancher cluster plus the downstream RKE2/K3s clusters it provisions. Covers the community release model (2.11→2.15, community-vs-Prime cadence, EOL), the Kontainer Driver Metadata (KDM) matrix deciding which downstream k8s minors each Rancher version can manage (and the stranding risk when a host-Rancher bump outruns its sub-clusters), cross-cluster upgrade ordering, the embedded-.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
