The nudge bot is a tool that helps to keep code reviews on GitHub moving. It works by monitoring open pull requests (PRs) and detecting when they are blocked. When the bot detects that a PR is blocked, it automatically sends a nudge message to the author or code reviewer. This message serves as a reminder to take a look at the PR, and hopefully get it unblocked and moving forward. The nudge bot is a simple and effective way to keep code reviews on track and ensure that pull requests are reviewed in a timely manner. The Nudge Bot for Github has been inspired by the research paper titled "Nudge: Accelerating Overdue Pull Requests toward Completion" available at https://dl.acm.org/doi/abs/10.11... . The Nudge Bot will identify overdue pull requests, send automated nudges, and track the effectiveness of nudges. Nudge Bot is now available for free for both private and public repositories on GitHub! To install Nudge Bot for your repositories, simply visit the GitHub marketplace and you will be able to “Install” it for free. It also has an optional integration with Slack available.
