Node.js package manager with strict dependency resolution. Use when running pnpm specific commands, configuring workspaces, or managing dependencies with catalogs, patches, or overrides.
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.
