iterationlayer Extract Terms and Generate a Simplified Summary
Legal agencies and compliance teams use this pipeline to process vendor or partner terms — extracting key clauses like liability limits, termination conditions, and data handling provisions, then generating a plain-language summary for non-legal stakeholders.

Extract key clauses from the terms document at [file URL], then generate a plain-language summary. Use the extract_document tool with these fields:
- document_title (TEXT): Title of the terms document
- effective_date (DATE): Effective date of the terms
- parties (TEXT): Parties to the agreement
- termination_clause (TEXTAREA): Termination conditions and notice period
- liability_limitation (TEXTAREA): Liability limitation or cap
- indemnification (TEXTAREA): Indemnification obligations
- data_handling (TEXTAREA): Data processing and privacy provisions
- governing_law (TEXT): Governing law and jurisdiction
- payment_terms (TEXT): Payment terms and conditions
- auto_renewal (BOOLEAN): Whether the agreement auto-renews
Then use the generate_document tool to create a PDF summary with each clause explained in plain language, organized under clear headings.
