engineering skillA

engineering is agent-read markdown (skill) from wellwelwel/lagune: Authoritative engineering reference for Lagune, covering the toolchain, code conventions, type rules, the build and distribution path, and how the tracking hooks work. Use before writing or changing source under src/ or test/, or before the build..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Lagune engineering

This skill is the specialized, authoritative description of **how Lagune is built**: the toolchain, code conventions, type rules, the build and distribution path, and the implementation of the deterministic tracking hooks. Consult it before writing or changing source, before touching the build, and whenever you apply the code conventions.

The product mission and workflow philosophy live in [CLAUDE.md](../../../CLAUDE.md). The repository layout, the command/template split, the core/adapter boundary, what Lagune scaffolds, and the tracking-map model live in the [architecture](../architecture/SKILL.md) skill. This skill covers the _build_, not the _shape_.

## Toolchain

- **Runtimes:** Node.js (current LTS), Bun, and Deno. Lagune must run on all three, so keep code runtime-agnostic.
- **Language:** TypeScript, authored in `src/`.
- **Module system:** ES Modules only (ESM) throughout.
- **Package manager:** npm, matching the npx/npm distribution path.
- **Bundler:** esbuild (transpile and bundle only, it does not type-check).
- **Type-checking:** `tsc --noEmit`, run separately since esbuild skips type checks.
