Drafts long-form copy against your brief, voice guide and facts.
Content Writer produces first drafts that are worth editing: blog posts, product pages, help articles and release notes, written against a brief you supply, in a voice defined by examples you provide, using only facts you hand it.
The agent works from a fact sheet you supply and will not assert anything outside it. Where the brief demands a claim the facts do not support, it inserts a marked gap for you to fill rather than inventing a statistic. This constraint is the whole reason the output is usable.
Telling a model to write "professional but friendly" produces the same beige prose for everyone. Instead you supply three or four pieces of your existing writing and the agent matches sentence rhythm, vocabulary and structural habits against them.
We will not claim otherwise. The output is a solid draft that saves a writer the blank page and most of the structural work. It still needs an editor. Anyone selling you unattended publishing is selling you a reputation problem.
