pnpm

The pnpm skill is a practical reference for managing Node.js dependencies with pnpm, covering package installation, monorepo workspace configuration, pnpm catalogs, dependency overrides, patching third-party packages, and CI pipeline setup. It solves the problem of navigating pnpm's content-addressable store, strict dependency model, workspace protocol, and catalog system, which differ meaningfully from npm and yarn and are easy to misconfigure.

The main document offers a quick-start command set and workspace setup examples, then routes deeper questions to four focused reference files: cli.md for commands, scripts, and filtering; workspaces.md for workspaces, catalogs, and .npmrc configuration; features.md for overrides, patches, hooks, and store management; and ci.md for CI/CD, Docker, and migration. The references are detailed, documenting the workspace protocol variants and how they publish, named and default catalogs with their mode settings, .npmrc hierarchy and settings, the package.json pnpm field (overrides, peerDependencyRules, patchedDependencies, onlyBuiltDependencies), filtering by name, directory, glob, dependency graph, and changed-since-git-ref, and publishing flags. The skill instructs the agent to load only the reference relevant to the current task rather than all files at once, and includes a verification step to confirm a workspace links and builds.

Target users are JavaScript and TypeScript developers and platform engineers working in pnpm-managed repositories, especially monorepos, who need reliable guidance on workspace layout, centralized version management, transitive dependency control, and CI configuration. It also cross-references sibling skills for TypeScript libraries and build tooling.
