GitHub Generated-File Auto-Viewer is a free Chrome extension designed to streamline the management of pull requests on GitHub. This tool specifically targets the **Files changed** tab, allowing users to automatically mark generated files as viewed based on user-defined glob patterns. It is particularly useful for developers who deal with numerous files in pull requests, as it reduces the clutter of unnecessary files that do not require line-by-line scrutiny.

The extension caters to various file types, including lockfiles, generated protobufs, code generation outputs, build artifacts, and snapshots. By automating the viewing process, users can focus on the relevant changes without being distracted by files that are not essential to review. This functionality enhances productivity by minimizing the manual effort required to manage pull requests effectively.
