@catana-dev done requests Catana to open a Pull Request and delete a TODO from your source code.
When a TODO becomes ready to be addressed, Catana opens an issue to notify its assignee. If you decide that this TODO no longer applies, the right action is to remove it from your source code.
To make things easier for you and your team, you can type
@catana-dev done in a comment on the issue.
Catana will delete the TODO line, open a Pull Request and request your review.
It saves you time and avoids switching context only to remove one line.
