What does this rule do?

Checks for likely outdated messages. A message with a missing source is usually an indication that the message (id) is no longer used in source code, but messages have not been updated accordingly.

Manual setup

Besides installing the lint rule through manage.inlang.com you could also configure it manually.

Settings
