`bootstrap.sh --with-hermes` installs the Goose CLI, drops a Goose config pinning the OpenRouter provider + Nous Hermes model + the homelab MCP extension, symlinks `bin/hermes` and HERMES.md, and links HERMES.md as `.goosehints` so the persona is injected as the system prompt every session. `bin/hermes` decrypts `secrets/openrouter-api-key.yaml` via the existing `homelab secret` flow and execs `goose session`. `homelab client add --with-hermes` grants the new sops secret to the host's age_pubkey at finalize time (parallel to the existing shared-secrets grant). `client remove` revokes it. `operations/hermes-agent.md` covers the end-to-end flow, verification, troubleshooting, and queues one follow-up: the MCP server still runs SSE-only but Goose 1.x deprecated SSE — the Goose config targets `streamable_http` and the `homelab` extension won't connect until `mcp/server.py` migrates. The `developer` extension (shell + edit + `homelab` CLI) carries the agent in the meantime. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

homelab — single-binary CLI for managing the hubris homelab from any client.
|

|
Reads /opt/homelab-context/inventory.yaml as the source of truth, resolves
|
|
hostnames to mesh addresses, and wraps the common ops (ssh, pct, logs, restart,
|
|
status, open, secret, client add/remove, sync, mcp).
|

Mutating subcommands prompt unless -y / --yes is passed.
|
|

Run `homelab --help` or `homelab <subcommand> --help` for usage.
