Problem: "Hermes" collides with Nous Researchs unrelated product; unclear identity for the resident agent. Change: Rename the live service identity across 39 files: - cmd/hermes/ → cmd/nomos/ (binary, env vars NOMOS_*) - internal/config/ server.go (NomosAgentSlug, nomosAgentID) - compose/hermes/ → compose/nomos/ (Dockerfile, service name) - hermes/ → nomos/ (SOUL.md, config.yaml, skills/) - .agents/HERMES.md → NOMOS.md (persona) - tools/setup-hermes-soul.sh → setup-nomos-soul.sh - seeds/inventory.yaml (agent:hermes → agent:nomos) - migrations/014_rename_agent_hermes_to_nomos.up.sql - Caddy vhost hermes.hubris.network → nomos.hubris.network - All referencing docs, scripts, ADR notes History preserved: archive/, plans/done/, ADRs not rewritten. Matrix @hermes notifier account and Legacy bin/hermes on LXC 129 intentionally untouched (out of scope). Risk: N0 is identity-only rename; zero behavioral changes. Verification: go build ./... passes; docker compose --profile full resolves nomos service; grep -ri hermes (excluding archive/plans) returns only intentional refs (LLM model name, Matrix user).

# Oikos — client guide
|
|
|
|
If you are a homelab machine, this is what Oikos is and what it gives you.
|
|
If you are an AI agent running on this machine, also read [AGENTS.md](AGENTS.md).
|
|
|
|
## What is Oikos?
|
|
|
|
Oikos is the agentic operating system for the **hubris** Proxmox homelab. It
|
|
observes state, classifies actions against policy, executes approved
|
|
procedures, learns from outcomes, and notifies the operator. It runs as a
|
|
Docker stack on mac-mini and exposes an MCP server + REST API.
|
|
|
|
## What Oikos provides
|
|
|
|
| Capability | How you access it |
|
|
|------------|-------------------|
|
|
| Entity query (topology, blast radius) | MCP `get_entity`, `get_blast_radius` |
|
|
| Full-text knowledge search | MCP `search_knowledge` |
|
|
| Service status + logs | MCP `get_service_status`, `tail_log` |
|
|
| LXC inventory + state | MCP `list_lxcs`, `get_lxc_state` |
|
|
| Context cards | MCP `explain` |
|
|
| Pre-flight risk classification | MCP `preflight` |
|
|
| Change history | MCP `get_change_history` |
|
|
| State snapshot (health, disk, drift) | MCP `get_state_snapshot` |
|
|
| Secrets (Infisical) | REST API + `oikos secret` CLI |
|
|
| Approval tokens | Matrix via notifier |
|
|
|
|
All MCP tools are read-only. Mutations use the `homelab` CLI with operator
|
|
approval.
|
|
|
|
## Enrollment
|
|
|
|
Thin client model — no git clone, no sync timer. `bootstrap.sh` fetches only
|
|
the agent orientation files and tooling from the raw Gitea URL, then enrolls
|
|
via the Oikos API.
|
|
|
|
To enroll:
|
|
```bash
|
|
# Run from any machine with mesh connectivity
|
|
curl -fsSL https://git.hubris.network/dtoro/oikos/raw/main/bootstrap.sh | sudo bash
|
|
|
|
# Or with optional tooling:
|
|
curl ... | sudo bash -s -- --with-mcp # wire Claude's MCP config
|
|
curl ... | sudo bash -s -- --with-nomos # install Goose + Nomos
|
|
```
|
|
|
|
This calls `POST /api/v1/clients/enroll` on the Oikos API, which:
|
|
1. Validates the entity exists in DB (planned or provisioning state)
|
|
2. Validates mesh IP against expected subnets
|
|
3. Generates an age keypair and delivers it to the client
|
|
4. Creates an Infisical machine identity
|
|
5. Transitions the entity to provisioning state
|
|
|
|
## After enrollment
|
|
|
|
### What changes on your machine
|
|
|
|
- `/opt/homelab/` — agent orientation files (CLIENTS.md, AGENTS.md, OIKOS.md)
|
|
- `/opt/homelab/tools/` — tooling scripts (caveman, nomos-soul)
|
|
- `/etc/age/key.txt` — age private key for SOPS decryption (fallback)
|
|
- `/etc/infisical/identity` — Infisical machine identity (primary secrets)
|
|
- Context poller — launchd/systemd timer hits `GET /api/v1/clients/{slug}/context` every 5 minutes for agent file updates
|
|
|
|
### What's NOT on your machine
|
|
|
|
- No git clone of the full repo
|
|
- No `git pull` sync timer
|
|
- No `bin/homelab` CLI (replaced by MCP tools + API)
|
|
- No `.sops.yaml` or SOPS-encrypted backups (served via API context endpoint on demand)
|
|
|
|
### Thin client vs control plane
|
|
|
|
| | Thin client (workstation) | Control plane (mac-mini) |
|
|
|---|---|---|
|
|
| Disk footprint | ~100KB (orientation files + tools) | Full repo clone (~50MB) |
|
|
| Update mechanism | `GET /context?since=` poll | Git pull + post-pull.sh |
|
|
| Source of truth | DB via MCP | DB + local seeds + archive |
|
|
| Secrets access | Infisical (primary), age/SOPS served via API (fallback) | Infisical + local SOPS files |
|
|
|
|
### Your identity
|
|
|
|
Your identity in the homelab is defined in `inventory.yaml`. Run `hostname`
|
|
(Linux) or `scutil --get LocalHostName` (macOS), then look up your entry.
|
|
It tells you your role, what services you host, what's mounted, and your
|
|
mesh address.
|
|
|
|
### Source of truth hierarchy
|
|
|
|
1. **Postgres database** (runtime) — authoritative for entities, knowledge,
|
|
signals, ledger. Query via MCP or REST API.
|
|
2. **Context poller** — agent files and tooling fetched via API deltas every
|
|
5 minutes.
|
|
3. **Never guess.** If data is missing, query MCP. If MCP is down, grep the
|
|
local `/opt/homelab/` files.
|
|
|
|
## The context poller
|
|
|
|
Every 5 minutes, launchd (macOS) or systemd (Linux) hits:
|
|
|
|
```
|
|
GET /api/v1/clients/ws:{hostname}/context?since={last_timestamp}
|
|
```
|
|
|
|
The API returns which agent files, tools, and SOPS config changed since the
|
|
last poll. Only changed files are downloaded. This replaces the old
|
|
`git pull` with a lightweight HTTP delta.
|
|
|
|
To trigger manually: run `/opt/homelab/tools/context-poller.sh`.
|
|
|
|
## Making changes
|
|
|
|
- **Read state**: use MCP tools or the API
|
|
- **Mutate state** (restart, edit config, deploy): classify the action against
|
|
policy (query `preflight` MCP tool):
|
|
- `read_only` / `reversible_low` — execute directly
|
|
- `config_mutation` / `destructive` — request operator approval via
|
|
`POST /api/v1/entities/{slug}/activate` (or equivalent lifecycle endpoint)
|
|
- **Secrets**: use Infisical (primary) or SOPS (fallback). Never hardcode.
|
|
- **Knowledge**: if you observe a discrepancy between docs and live state,
|
|
update the DB via the API in the same session.
|
|
|
|
## MCP endpoint
|
|
|
|
```
|
|
https://mcp.hubris.network/mcp
|
|
```
|
|
|
|
Available tools are listed in [AGENTS.md](AGENTS.md#3-the-mcp-server).
|
|
|
|
## Communication mode
|
|
|
|
Apply [.agents/shared/caveman.md](.agents/shared/caveman.md) — terse,
|
|
fragment-heavy communication. Drop filler, keep substance.
