Final answer:
If you don't provide a commit message, version control systems such as Git will prompt for one. Commit messages are vital for documentation and undocument commits aren't finalized. Writing meaningful messages is a best practice for project history clarity.
The statement "if you do not add a message to a commit, a prompt will ask you for one" is True.
Step-by-step explanation:
If you do not add a message to a commit, most version control systems, like Git, will indeed open up a text editor prompting you to write a commit message before completing the commit process. Without a commit message, the commit will not be finalized because commit messages serve as valuable documentation for the changes introduced in that commit.
It is considered a best practice to write meaningful commit messages to make tracking changes and understanding the project history easier.
