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).

Developer guide for the Oikos codebase. If you are a homelab client consuming
|
|
Oikos, see [CLIENTS.md](CLIENTS.md). If you are an AI agent working on the
|
|
repo, see [.agents/dev/CONTRIBUTING.md](.agents/dev/CONTRIBUTING.md).
|
|
|
|
## Dev setup
|
|
|
|
- **Go 1.26+** (see `go.mod` for pinned version)
|
|
- **PostgreSQL with TimescaleDB** — the compose stack includes `timescale/timescaledb:2.17.2-pg16`
|
|
- **Docker** for the full dev stack
|
|
|
|
```bash
|
|
# Start dependencies (Postgres + Redis)
|
|
docker compose --profile dev up -d
|
|
|
|
# Run all tests
|
|
make test
|
|
|
|
# Run integration tests (needs compose Postgres)
|
|
make test-db
|
|
|
|
# Build the binary
|
|
make build
|
|
```

## Conventions
|
|
|
|
### APIs are OpenAPI-first
|
|
|
|
The REST API is defined in `api/openapi.yaml`. Server code is generated with
|
|
`oapi-codegen` into `internal/httpapi/gen/`. To add an endpoint:
|
|
|
|
1. Add the path + schema to `api/openapi.yaml`
|
|
2. Run `make generate`
|
|
3. Implement the handler in `internal/httpapi/impl.go`
|
|
4. Add tests in `internal/httpapi/api_test.go`
|
|
|
|
Never hand-edit `internal/httpapi/gen/api.gen.go`.
|
|
|
|
### Database access is sqlc-first
|
|
|
|
SQL queries live in `internal/db/queries/*.sql`. Go code is generated with
|
|
`sqlc` into `internal/db/sqlcgen/`. Config in `sqlc.yaml`.
|
|
|
|
- Queries target pgx/v5 with UUID + timestamptz overrides
|
|
- Never hand-edit generated sqlc code
|
|
|
|
### Migrations are forward-only
|
|
|
|
SQL migrations live in `migrations/` as `NNN_name.up.sql`. There are no down
|
|
migrations (see [ADR 0008](docs/adr/0008-forward-only-migrations.md)).
|
|
Migrations are idempotent where possible (`IF NOT EXISTS`, `DO $$` blocks).
|
|
|
|
To add a migration:
|
|
|
|
1. Create `migrations/NNN_name.up.sql` with the next sequence number
|
|
2. Write the DDL
|
|
3. Run `make migrate` to apply
|
|
|
|
### Seeds are DB-generated
|
|
|
|
`seeds/*.yaml` are the bootstrap files used by `oikos seed`. After making
|
|
changes via the API, run `make export` to regenerate the seed files. These
|
|
files are version-controlled and serve as DR fallback.
|
|
|
|
### Writing style
|
|
|
|
Follow [.agents/shared/writing-style.md](.agents/shared/writing-style.md).
|
|
Documentation is reference prose, not marketing. Banned vocabulary includes
|
|
"robust", "seamless", "leverage", "utilize", "delve", "cutting-edge".
|
|
|
|
### Risk classification
|
|
|
|
Every mutation is classified against `seeds/policy.yaml` before execution.
|
|
Four risk classes: `read_only`, `reversible_low`, `config_mutation`,
|
|
`destructive`. The classifier can only lower autonomy relative to policy,
|
|
never raise it. When in doubt, escalate.
|
|
|
|
## CI
|
|
|
|
Gitea Actions runs on push to `main` and pull requests (`ci.yml`):
|
|
|
|
1. `go vet` + `golangci-lint` + `govulncheck`
|
|
2. Generated code drift check (`make generate-check`)
|
|
3. Build (`go build ./...`)
|
|
4. Test with race detector + coverage
|
|
5. Docker build verification (no push)
|
|
|
|
Coverage gates: policy + learning packages ≥ 80%, others ≥ 60%.
|
|
|
|
## PR workflow
|
|
|
|
1. Create a branch from `main`
|
|
2. Make changes, write tests
|
|
3. Run `make lint test generate-check`
|
|
4. Commit with a message following: problem → change → risk → verification
|
|
5. Push to Gitea; CI gates PRs on green
|
|
|
|
## Secrets
|
|
|
|
Secrets are managed by Infisical (primary) with SOPS as DR fallback. Never
|
|
hardcode secrets. Use environment variables from `.env` for local dev.
|
|
The `.env` and `.infisical-credentials` files are gitignored.
