Please always format the Texinfo sources with lines that don't exceed
80 characters, preferably even 72.

I would leave only the latter @dfn, there seems to be no need for the
former one, as you don't describe the agent in this section.

I don't understand what you wanted to say in this sentence.  Does it
really add anything important?

Again, this @dfn is not appropriate here, because this section does
not explain this term.

@kindex is missing here.  All commands should be indexed.

Don't we also have "show agent"?

Anyway, full section for just 2 commands seems like a waste of a
section.  Why not make it part of its parent chapter.
