arch-tsdown-monorepo is a pnpm monorepo starter for TypeScript libraries (based on hairyf/starter-monorepo). Each package uses tsdown for building. It provides shared tooling (ESLint, Vitest, TypeScript), pnpm catalogs for versions, workspace dependencies, and optional npm Trusted Publisher for CI-based releases.

The skill is based on hairyf/starter-monorepo, generated at 2026-02-02.

Recommended practices:

Use pnpm catalogs for devDependency versions; reference with catalog:cli, catalog:testing, etc.
Use workspace:* for inter-package dependencies; publish once manually, then use npm Trusted Publisher for CI releases.
Run build/typecheck/test from root with pnpm -r run ... and a single Vitest config with projects (root + packages/*).
