Nx Plugins

This gives Claude the ability to discover and install Nx plugins in your workspace. It knows two commands: `pnpm nx list` to see what's available and `pnpm nx add <plugin>` to install them. Useful when you're setting up framework support like React or adding tooling integrations without leaving the conversation. The source is intentionally minimal, just the core commands, but that's really all you need since Nx's plugin ecosystem is well documented elsewhere. Honestly most valuable when you're in the flow and don't want to context switch to look up which plugin handles Next.js or Vite.
