At my workplace, we have a lint rule that reports an error if @nocommit is anywhere in the file, plus a commit hook that blocks all commits with @nocommit anywhere in them. It works well and has saved me a few times.
Works pretty well, except the lint rule and its associated tests have to do something like "@no"+"commit" to avoid triggering it,
In a lot of modern work flows this is incompatible with the development pattern.
For example, at my job we have to roll a test release through CI that we then have to deploy to a test kubernetes cluster. You can't even do that if the build is failing because of linting issues.
The test release shouldn't have anything marked with @nocommit though... The idea is that you use it to mark code that is only temporary local debugging code that should never be committed.
Are you committing to master? I don't see any reason why you shouldn't commit your debugging code to your own branch. Obviously clean it up before merging
