pnpm

厳格な依存関係解決を備えたNode.jsパッケージマネージャー。pnpm固有のコマンドの実行、ワークスペースの設定、依存関係の管理などに使用します。

pnpm is a fast, disk space efficient package manager. It uses a content-addressable store to deduplicate packages across all projects on a machine, saving significant disk space. pnpm enforces strict dependency resolution by default, preventing phantom dependencies. Configuration should preferably be placed in pnpm-workspace.yaml for pnpm-specific settings.

Important: When working with pnpm projects, agents should check for pnpm-workspace.yaml and .npmrc files to understand workspace structure and configuration. Always use --frozen-lockfile in CI environments.

The skill is based on pnpm 10.x, generated at 2026-01-28.
