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.
