- Use imperative/guide language (e.g. "açalım", "gidin", "kopyalayalım", "bir bakalım").
- Avoid filler words and overly long sentences.
- Ensure sentences make sense in Turkish context — adjust structure, conjunctions, and verb forms as needed for natural flow (e.g. use "Ancak" instead of "Ve" when connecting contrasting sentences, use "-maktadır/-mektedir" for formal statements).
