Extraction Prompts for Unstructured Docs (ANSWERED)
Schema-first extraction from PDFs, emails, and contracts with validation, chunking, and merge strategies.
TL;DR — Quick Answer
Provide an explicit schema, chunk documents with overlap, extract per chunk with citations, then merge and validate with deterministic checks (dates, amounts, regex). Use structured output modes, low temperature, and retry on schema validation failures rather than trusting one-shot extraction on long docs.
