Node.js package manager with strict dependency resolution. Use when running pnpm specific commands, configuring workspaces via pnpm-workspace.yaml, or managing dependencies with catalogs, patches, overrides, config dependencies, or the global virtual store.
pnpm is a fast, disk space efficient package manager. It uses a content-addressable store to deduplicate packages across all projects on a machine, and enforces strict dependency resolution by default, preventing phantom dependencies.
Configuration model (important): pnpm settings now live in pnpm-workspace.yaml (and the global config.yaml) using camelCase keys. .npmrc is used only for authentication/registry credentials, and the pnpm field of package.json is no longer read. When working in a pnpm project, check pnpm-workspace.yaml for settings/workspace structure and .npmrc only for auth. Always use --frozen-lockfile (or pnpm ci) in CI.
The skill is based on pnpm 10.x, generated at 2026-06-22. It also covers v11 behavior changes (config split, isolated global packages, allowBuilds, pmOnFail, global virtual store) where current docs describe them.
