| PROMPT ="""Please analyze the provided images of the real estate document set and perform the following actions: | |
| 1. *Identify Parties:* Determine and list Seller 1, Seller 2 (if applicable), Buyer 1, and Buyer 2. | |
| 2. *Identify Missing Items:* Locate and list all instances of missing signatures and missing initials for all parties across all documents. | |
| 3. *Identify Checked Boxes:* Locate and list all checkboxes that have been marked or checked. | |
| 4. *Generate Secondary Questions:* For checkboxes that indicate significant waivers (e.g., home warranty, inspection rights, lead paint assessment), specific conditions (e.g., cash sale, contingency status), potential conflicts, or reference other documents, formulate a relevant 'Secondary Question' designed to prompt confirmation or clarification from the user/parties involved. | |
| 5. *Check for Required Paperwork:* Based only on the checkboxes identified in step 3 that explicitly state or strongly imply a specific addendum or disclosure document should be attached (e.g., "Lead Based Paint Disclosure Addendum attached", "See Counter Offer Addendum", "Seller's Disclosure...Addendum attached", "Retainer Addendum attached", etc.), check if a document matching that description appears to be present within the provided image set. Note whether this implied paperwork is 'Found', 'Missing', or 'Potentially Missing/Ambiguous' within the provided images. | |
| 6. *Identify Conflicts:* Specifically look for and note any directly contradictory information or conflicting checked boxes (like the conflicting inspection clauses found previously). | |
| 7. *Provide Location:* For every identified item (missing signature/initial, checked box, required paperwork status, party identification, conflict), specify the approximate line number(s) or clear location on the page (e.g., Bottom Right Initials, Seller Signature Block). | |
| 8. *Format Output:* Present all findings comprehensively in CSV format. The CSV columns should be: | |
| * Category (e.g., Parties, Missing Item, Checked Box, Required Paperwork, Conflict) | |
| * Location (Document Name/Page, e.g., Sale Contract Pg 2) | |
| * Line Item(s) (Approximate line number or location description) | |
| * Item Type (e.g., Seller Initials, Home Warranty Waiver, Lead Paint Addendum Check, Lead Paint Addendum Document) | |
| * Status (e.g., Identified, Missing, Checked, Found, Potentially Missing, Conflict Detected) | |
| * Details (Specifics like names, text of the checkbox, description of the issue or document status) | |
| * Secondary Question (if applicable) (The question generated in step 4) | |
| Please apply this analysis to the entire set of documents provided. | |
