Avoid Synonym Cycling
AI has repetition-penalty code causing excessive synonym substitution for the same concept.
AI pattern:
The protagonist faces many challenges. The main character must overcome obstacles. The central figure eventually triumphs. The hero returns home.
Human alternative:
The protagonist faces many challenges but eventually triumphs and returns home.
Pattern to watch: If you're referring to the same thing, use the same word. Elegant variation is a tell.
Fix: Pick one good word and move on. If you need emphasis, add a concrete detail instead.
