new-file
An advisory: it explains, and blocks nothing, on a new file in a directory whose naming has settled.
What it catches
A new file in a directory whose naming has settled.
Seeing it
A verdict names its rule in brackets, which is how you got here:
advise [new-file]: ...
magus describe rule new-file prints the same entry at a terminal, and
magus describe rules lists every rule this workspace enforces.
