Reality for a lot of us is several <em>standalone</em> servers, accumulated over the years, each with its own login, its own quirks, and no interest in joining anybody&rsquo;s cluster. This skill — built on danielbitpro/hermes-proxmox-control, extended with a host registry and a multi-host helper — lets one Hermes Agent session manage all of them.</p> <p>The part I&rsquo;m proudest of is the failure model: <code>get_all()</code> wraps each connection in its own try/except, so when pve3 is down for maintenance, listing VMs across the fleet returns results from pve1 and pve2 plus a clean error line for pve3 — not a crash. Secrets resolve through Bitwarden Secrets Manager by UUID at call time; the registry on disk maps hostnames to secret IDs and never stores a credential itself.</p>
