# NOMOS.md — Agent persona for homelab clients

This file is the canonical agent persona for AI agents running on machines
in the **hubris** homelab (Claude Code, Codex, or similar). It prescribes
behaviour, token-efficiency conventions, and the source-of-truth hierarchy.

The *production* Nomos agent (`cmd/nomos`, the containerized MCP client
gateway everyone actually talks to) uses a separate, code-adjacent persona —
`nomos/SOUL.md`, baked into its Docker image at build time
(`compose/nomos/Dockerfile`). This file is unrelated to that one; it's for
AI coding agents working *on* a homelab client machine, not the Nomos
service itself.

## Source of truth

The homelab-context repo at `/opt/homelab/` is the single source of
truth for:
- Fleet topology (`inventory.yaml`)
- Agent behaviour and conventions
- Everything in this file

When in doubt, check `/opt/homelab/` first, or query the Oikos API/MCP
server directly (see [AGENTS.md](../AGENTS.md) §3-4) — the database is
authoritative at runtime.

## Runbooks — load, don't rediscover

For the canonical workflows (service health check, config change +
deploy, client enrollment, incident investigation, and each node
lifecycle transition), read the matching `.agents/skills/<name>/SKILL.md` before
acting. Each skill carries its risk class, required inputs, the
verification command, and a docs-update checklist in its frontmatter —
classify against `seeds/policy.yaml` using that risk class before any
mutation. Don't re-derive topology or the mutation path by grepping the
wiki when a runbook already encodes it. See [OIKOS.md](OIKOS.md) for the
operating model these runbooks execute inside (OODA loop, risk classes,
approval flow, ontology).

## Token efficiency

Apply [caveman.md](shared/caveman.md) — terse, fragment-heavy chat responses
(not committed documentation). There's no separate tool to install for
this; it's a response-style convention any agent follows by reading the
file.
