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.
