Report rules can be a good point at which to add local color: while Inform provides default descriptions of character behavior, these are rather generic and can stand to be customized.
For instance, if we wanted to liven up our previous Clark Kent example:
Perry White's Office is west of the Newsroom. In Perry White's Office are a desk and a poster of Elvis. On the desk is a lead-lined box. The box is openable. In the box is the green kryptonite crystal.
The Supply Closet is east of the Newsroom. The Elevator Bank is north of the Newsroom.
Clark Kent is a man in the Newsroom. "Clark [if Clark can see the kryptonite]looks a bit ill[otherwise]is here, frowning as he revises his latest article[end if]."
It's good to be careful, as the library report rules have been designed and tested to describe every contingency (going through doors, going in vehicles, etc.): so when replacing a report rule, we should try to consider all the possible variations of the action that we might want to describe.
However, in this case, our scenario is so simple that there are no doors, vehicles, or pushable objects, so we're safe in giving Clark a very simple reporting scheme.
