When to use

Use this skill proactively for:

Installing dependencies
Adding or removing packages
Running scripts
Any command that involves a package manager

Instructions

Always use pnpm as the package manager. Before running any package manager command, check which package manager the project is already using:

If pnpm-lock.yaml exists → use pnpm
If yarn.lock exists → use yarn
If package-lock.json exists → use npm
If none exist (new project) → use pnpm

Never switch the package manager mid-project. If a project already uses npm, continue with npm throughout. Do not mix package managers in the same project.
