概要
The pnpm-upgrade skill provides a standardized workflow for maintaining the pnpm toolchain within a repository. It automates the local update process using corepack, ensures the package.json packageManager field is correctly aligned, and fetches the latest GitHub Action tags to update CI pipelines. By using precise file edits instead of broad regex replacements, it reduces the risk of configuration drift and ensures that development and continuous integration environments remain perfectly in sync with the latest pnpm releases.
