Pnpm

Handles Node.js dependency management with pnpm's content-addressable store and strict linking model. You'll want this when setting up monorepo workspaces with the workspace protocol, managing shared dependency versions through catalogs, or dealing with transitive dependency issues using overrides and patches. The skill covers CLI filtering for running commands across workspace packages, CI/CD configuration, and supply chain security hardening. Honestly, if you're already deep in npm or Yarn, the migration guidance here will save you from the usual workspace config headaches that come with switching package managers.
