# sow-tools / Crucible Agent Guide
This repo owns the **builder logic:** one Go module
(`git.westgate.pw/ShadowsOverWestgate/sow-tools`) producing the `crucible`
dispatcher and the `crucible-<name>` binaries.
## What it is / part it serves
Shadows Over Westgate (SoW) is a Neverwinter Nights: Enhanced Edition
persistent world, split into single-purpose repos. This repo is Crucible, the
Go build toolkit. The content repos hold game source (module areas, rules
data, binary assets) and call Crucible to turn that source into artifacts:
the `.mod` file, 2DA/TLK tables, HAKs, wiki pages. Crucible is the only place
builder logic lives; content repos only run it through thin wrapper scripts.
## Guidance map
| Where | What |
|-------|------|
| `cmd/crucible/`, `cmd/crucible-<name>/` | dispatcher + per-builder shims (thin `main.go` files) |
| `internal/dispatch/` | the command registry — single source of truth for the command surface |
| `internal/` (app, pipeline, project, erf, gff, topdata, changelog, validator, depot, menu, buildinfo) | the actual builder logic |
| `wrappers/` | canonical bootstrap wrappers (`crucible`, `crucible.ps1`) synced to consumer repos; `wrappers/consumers.txt` lists targets |
| `docs/command-surface.md` | every command, old `nwn-tool` name → new home |
| `docs/consumer-contract.md` | how consumer repos resolve/pin a Crucible binary |
| `docs/migration-from-nwn-tool.md` | migration status, what remains |
| `tests/`, `Makefile`, `flake.nix` | checks, targets, dev shell |
Task routing: adding/changing a command → read `docs/command-surface.md`
first, then `internal/dispatch`. Changing how consumers get binaries →
`docs/consumer-contract.md` + `wrappers/`. Release/CI questions → README "CI"
section and `.gitea/workflows/`.
## How it is used
- Dev loop: `nix develop`, then `make check` / `make build` / `make smoke`
(see Commands below).
- Release: push a `v*` tag. CI uploads cross-built binaries + wrappers to the
Gitea release and publishes the `crucible` container image.
- Consumers (they download released binaries via the wrapper; they never
vendor a toolkit):
- sow-module — https://git.westgate.pw/ShadowsOverWestgate/sow-module
- sow-topdata — https://git.westgate.pw/ShadowsOverWestgate/sow-topdata
- sow-assets-manifest — https://git.westgate.pw/ShadowsOverWestgate/sow-assets-manifest
- sow-platform (deploys the released image/pins) —
https://git.westgate.pw/ShadowsOverWestgate/sow-platform
## What this repo owns / does not own
Owns: build/extract/validate/compare pipeline, ERF/HAK packing, topdata 2da/tlk
compilation, wiki rendering/deploy, depot blob verify, changelog. Does **not**
own authored game content (that is `sow-module` /
`sow-topdata` / `sow-assets-manifest`) or any production deploy authority (that
is `sow-platform`).
## Rules
1. **Fail closed, never fake.** A builder with no migrated logic yet (`depot`)
exits `70`. Do not stub a builder to emit a placeholder artifact.
2. **Binaries are not committed.** They are CI artifacts / image layers.
`/bin/`, `*.exe`, `nwn-tool`, `sow-toolkit` are gitignored.
3. **The registry is the command surface.** `internal/dispatch.Registry` is the
single source of truth; keep it in sync with `cmd/` and
[`docs/command-surface.md`](docs/command-surface.md). Adding a builder = a
`cmd/crucible-<name>/main.go` shim + a `Registry` entry + a doc row.
## Wiring a builder
1. Ensure the relevant `internal/` package(s) cover the work.
2. Add tests; keep outputs deterministic (same input → same bytes).
3. `make check` must stay green; update `make smoke` to expect the wired exit.
## Commands
```bash
nix develop && make check # vet + test + shellcheck + yamllint
make build # cmd/* -> ./bin
make smoke # assert fail-closed contract
make image # crucible:<sha>
```
## Tests
Tests must survive harmless changes to constants, defaults, wording, ordering, fixture data, and internal implementation details. A test that fails merely because a basic value changed is usually a bad test. Only assert exact values when the value is part of a documented public contract, external protocol, compatibility requirement, security rule, migration, or business rule.
