LLM extraction errors fixed with corrective prompting and confidence scoring

A developer encountered issues with LLM-powered data extraction, specifically when models returned near-valid JSON that caused parsing errors. The solution involved a retry mechanism that fed the invalid response back to the LLM with corrective instructions, successfully resolving about 90% of these errors. Additionally, a per-field confidence scoring system was implemented to provide auditable insights into the reliability of individual extracted data points, enabling downstream systems to prioritize human review for low-confidence fields.
