Merge Manners is a Chrome extension designed to enhance GitHub pull request management by preventing accidental merges of pull requests that the user did not author. This free add-on addresses a common issue faced by developers, allowing them to review, comment, and approve pull requests without the risk of unintentionally merging someone else's work. It allows merges from bots while ensuring human errors are minimized.

The extension effectively detects whether the user is the author of the pull request, if they have pushed commits to it, and can recognize bot-created PRs. Users can configure custom bot patterns for added flexibility. For occasions when manual merging is necessary, Merge Manners offers a simple one-minute override option via the extension icon. Notably, it does not collect user data and supports settings synchronization through Chrome.
