description: 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.
