Watch out for

LLMs may hallucinate facts so include a disclaimer or fact-checking step before publishing.
Google Sheets has row limits and API quotas so implement pagination or batch processing for large lists.
SEO keywords might be stuffed unnaturally so add a constraint in the prompt to prioritize readability over keyword repetition.
Duplicate submissions can occur if the trigger fires multiple times so use unique IDs or timestamps to verify row integrity.
