Guard is a command-line tool that watches files and runs tasks automatically when they change, boosting Rails developer productivity.
It integrates with plugins for RSpec, Minitest, RuboCop, and more, allowing you to continuously run tests, linting, or other tasks during development.
Setup requires adding the gem, initialising with `guard init`, and configuring a Guardfile. It supports Rails 6, 7 and 8 on Ruby 3+.
Strengths include automation and immediate feedback, while weaknesses are configuration overhead for complex projects. Alternatives include rerun, entr, or IDE integrations.
