# Go Library Builder Scaffolds a new **reusable Go library module** in the ralvarezdev house style, distilled from the `identity`, `ratelimit`, and `email` libraries. This skill is the *composition root* for three others — it does not restate them: - **[go-architect](../../languages/go-architect/SKILL.md)** — every Go idiom (memory alignment, errors, iterators, linters, `//go:embed` SQL). This skill assumes it. - **[hexagonal-arch](../../design/hexagonal-arch/SKILL.md)** — ports & adapters, dependency direction. This skill applies it *at library scale*. - **[ddd-architect](../../design/ddd-architect/SKILL.md)** — entities, value objects, bounded contexts. This skill uses it for domain shape. Also leans on [repo-tooling-architect](../../tooling/repo-tooling-architect/SKILL.md) (mise/Task/editorconfig/renovate) and [sql-architect](../../databases/sql-architect/SKILL.md) (persistence adapters). File skeletons and full tooling templates live in [RECIPES.md](RECIPES.md) and [assets/](assets). Pinned versions in [STACK.md](STACK.md). ## 1. What it produces A standalone Go module publishable as `<namespace>/<name>` where **hexagonal layers map onto Go package boundaries**, not layer-named folders. There is never a `domain/`, `application/`, `ports/`, or `adapters/` directory — the package *is* the layer. **`<namespace>` is a parameter** — ask for it at bootstrap (§13.1); default `github.com/ralvarezdev`. It sets the module prefix, every intra-repo import path, `goimports -loca
