A document classifier routes new types through instruction generation and failed validation into instruction refinement, while known types reuse stored instructions and failed records return to data correction without changing guidance.

Summary: An AWS walkthrough coordinates eight specialized agents for document identification, extraction, validation and instruction updates. Textract supplies document content; database checks detect mismatches, while a repair agent revises stored extraction guidance for later examples. Its purchase-order timing comparisons come from illustrative runs, not a representative benchmark, and successful adaptation still depends on reliable rules.

Why it matters: Finance or operations teams can pilot one recurring document type with a fixed truth set. Track field-level errors, approve instruction changes before reuse, and retain original files for audit. Measure exceptions and regressions, not just faster second-pass processing.
