Fixes D1-D3 of plans/2026-07-11-nomos-agent-code-review.md: - D1: deleted isTaskTool — defined, never called (dispatch already checks handleTaskTool's own `handled` return value). - D2: recordTouched issued one SELECT per entity slug found in a tool call's args; batched into one `WHERE slug = ANY($1)` query. Verified live: a turn naming three separate entities recorded involves edges for all three via the single batched lookup. - D3: complete_task's outcome had a declared enum (success|failure|partial) in its tool schema but nothing validated it — an out-of-enum value (model typo or a weaker model not respecting the schema) silently persisted as-is, with only "failure" special-cased (anything else became status='done' regardless of what the value actually said). Now validated in handleTaskTool: empty defaults to "success" (unchanged), a recognized value passes through, anything else defaults to "partial" (safer than silently treating an unrecognized value as success) with a warning logged. Verified live: instructed the agent to call complete_task with outcome="unclear" — persisted as outcome='partial', not the literal invalid string.

Oikos
Agentic homelab operating system written in Go. Single binary (cmd/oikos),
Docker-deployed on mac-mini, with a standalone Nomos MCP agent gateway
(cmd/nomos). Manages the hubris Proxmox homelab autonomously — observes
state, classifies actions against policy, executes approved procedures over SSH,
learns from outcomes, and escalates when uncertain.
For agents running on enrolled clients: start with AGENTS.md. For client machines: see CLIENTS.md. For developers: see CONTRIBUTING.md.
Quick start
# Dev stack (postgres + api + scheduler + notifier)
docker compose --profile dev up -d
# Full stack (adds Nomos agent gateway)
docker compose --profile full up -d
# Build standalone binary
go build -o bin/oikos -tags timetzdata ./cmd/oikos
# Run all roles in one process (dev mode)

For agents
See AGENTS.md for the full orientation. Quick reference:
- Source of truth: DB (runtime) then seeds (bootstrap). Old wiki is
archived at
archive/knowledge/— use MCPsearch_knowledgeinstead. - Mutations: classify against policy, request approval for
destructive/config_mutation - Secrets: Infisical (primary) or SOPS (fallback) — never hardcode
