Seller's agent says the bonus room \"could add 200 sq ft\" if finished, but it isn't finished or counted.\n\n305 Fenway Street\nList price: $390,000.\nListing says \"approx. 1,700 sq ft,\" but the county record and the measurement report both say 1,500 sq ft.\n\nNotes: The Parks love the yard at Quarry Road. Fenway has a new roof. They're pre-approved up to $500,000 and want to keep monthly costs down, so they asked me to start with price per square foot before we talk about taxes or HOA fees. All three are single-family homes with no HOA.","rules":[{"type":"numberedItems","count":3},{"type":"plainText"}],"mistakes":[{"title":"Using the old price","why":"The original list price comes first, and the AI may miss the reduction.","fix":"Say: \"Use the current list price.\"","checks":["r0"]},{"title":"Using the listing's square footage","why":"\"Approx. 1,700\" is in the listing, but the measured number is lower.","fix":"Add: \"Use measured square footage, not listing estimates.\"","checks":["r0"]},{"title":"Adding opinions","why":"The AI weighs the yard and roof, which isn't what your clients asked.","fix":"Say: \"Output only the 3 lines and Lowest.\"","checks":["r2","r1"]},{"title":"Not saying how many","why":"The AI decides the length itself and usually returns more lines, one per home than you can use.","fix":"Be exact: \"exactly 3 numbered lines, one per home.\"","checks":["numberedItems"]},{"title":"Getting markdown back","why":"AI defaults to bold labels and headings, which show up as stray symbols in a text to your clients.","fix":"Ask for \"plain text, no bold, no headings.\"","checks":["plainText"]}],"promptHints":[{"label":"Asks for price per square foot","patterns":["per (sq|square)","/\\s*sq","price per"]},{"label":"Uses the current price","patterns":["current","reduced","latest","nov(ember)?\\.? 2"]},{"label":"Uses measured size","patterns":["measured","county record","not (the )?listing"]},{"label":"Says exactly how many","patterns":["\\b(3|three)\\b.{0,25}(line|home|listing)","exactly \\d+"]},{"label":"Asks for plain text","patterns":["plain","no bold","no markdown","no formatting","no headings"]}],"hint":"Price per square foot is only fair if both numbers are right.
