From the source SKILL.md

Plan, sequence, and de-risk a community-edition Harvester HCI upgrade across a real fleet — typically off an EOL line (1.5.x) up to the latest settled stable. The hard part is almost never the ISO/UI upgrade click. It is the coordination: Harvester is one bundle whose embedded RKE2, KubeVirt, Longhorn, SLE Micro, and Rancher pairing all move together, the upgrade controller picks its own node order, and the workloads that matter most — VM-hosted Kubernetes control planes — must stay quorate while each host reboots underneath them.

What this skill does

Harvester Upgrade is a community-contributed Claude Code skill in the devops sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/harvester-upgrade/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Harvester Upgrade Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 156,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
