Translation engine with a reviewer agent
A Brazilian outlet opened an international operation with its entire archive in Portuguese. The backlog had to be translated, and every new story after it, at the pace of a newsroom that doesn't stop to wait for a translator.
Two agents in a loop: one translates, the other grades the translation against the source and sends it back for correction until the score clears the bar. The language pair is a configuration parameter, so opening a new language doesn't mean touching the engine.
In production ever since, translating each story as it publishes. Human review sits at the point where it decides: an editor watches the queue and steps in when a text calls for judgment.
