The pnpm skill provides a Node.js package manager that resolves dependencies strictly, deduplicates packages via a content‑addressable store, and supports workspaces, catalogs, patches, and overrides. It is used to run pnpm commands, configure workspace settings, and manage project dependencies in monorepo environments, especially in CI where the lockfile must be frozen.
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.
