Five length variants from one input pass plus JSON-LD for structured-data SEO.</p>\n<p>Listing copywriting is the #1 most-adopted AI use case among real estate agents (multiple 2026 industry surveys). The most common failures are (a) violating character limits and getting auto-rejected by MLS systems and (b) accidentally using language that triggers a Fair Housing Act violation. Both are solved by construction.</p>\n<h1>============================================================\n=== PRE-FLIGHT ===</h1>\n<p>Gather and verify before writing:</p>\n<ul>\n<li><input disabled=\"disabled\" type=\"checkbox\"> <strong>Property facts.</strong> Required: address, beds, baths, sq ft, lot size, year built, asset type, list price. Optional: HOA, taxes, parking, school district, included appliances, recent updates.</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> <strong>Unique features.</strong> What makes THIS property different? (Renovated kitchen? View? Lot? Floor plan? Garage? Pool?) Without this the copy is generic and useless.</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> <strong>Target audience.</strong> First-time buyer, investor, downsizer, luxury, family — drives tone.</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> <strong>MLS system.</strong> Different MLSs have different character limits. Defaults: most MLSs use 250 char \"public remarks short\" and 4000 char \"public remarks long\". Confirm with user OR default to these and flag for verification.</li>\n<li><input disabled=\"disabled\" type=\"checkbox\"> <strong>Photos described.</strong> If photos are attached, run a vision pass to extract additional feature descriptors (white quartz countertops, dark hardwood floors, etc.) so the copy doesn't read generic.</li>\n</ul>\n<p>Recovery:</p>\n<ul>\n<li>If unique features are not provided, prompt with: \"What are 2-3 things that make this property stand out to a buyer?\" — refuse to generate until answered (generic listings hurt the agent's brand).</li>\n<li>If user has a brokerage style guide, request it. Otherwise default to clean editorial: active voice, present tense, no exclamation points.</li>\n</ul>\n<h1>============================================================\n=== PHASE 1: FAIR HOUSING COMPLIANCE GATE ===</h1>\n<p>Before writing any copy, load the banned-pattern list and apply it as a hard filter on ALL output.</p>\n<p><strong>HUD-enforced banned categories</strong> (Fair Housing Act, 42 U.S.C. § 3604):</p>\n<ul>\n<li>Race / color / national origin</li>\n<li>Religion</li>\n<li>Sex (including gender identity)</li>\n<li>Familial status (presence of children)</li>\n<li>Disability</li>\n</ul>\n<p><strong>Patterns that trigger violations</strong> (NAR + HUD guidance):</p>\n<ul>\n<li>\"Perfect for families\" → familial status implication; use \"spacious floor plan\"</li>\n<li>\"Empty nesters\" → familial status / age; use \"low-maintenance living\"</li>\n<li>\"Safe neighborhood\" → race-coded; describe specific amenities instead</li>\n<li>\"Walking distance\" → ableist; use \"X blocks\" or specific distance</li>\n<li>\"Master bedroom\" → use \"primary bedroom\" (NAR adopted 2020+)</li>\n<li>\"Exclusive community\" → coded language; use \"private\" only if literally gated</li>\n<li>\"Christian community\" / \"near temple\" → religious targeting</li>\n<li>\"Quiet street\" → fine, but pair with objective fact (\"cul-de-sac\")</li>\n<li>\"Original owner\" → fine</li>\n<li>\"Mother-in-law suite\" → use \"guest suite\" or \"accessory dwelling unit\"</li>\n<li>\"His and hers closets\" → use \"dual closets\"</li>\n<li>\"Maid's quarters\" → use \"guest suite\"</li>\n<li>\"Handyman special\" → fine</li>\n<li>\"Single-family\" → fine (refers to zoning, not occupancy)</li>\n</ul>\n<p>The compliance gate runs on the FINAL output, not the intermediate drafts. If any banned pattern is detected:</p>\n<ol>\n<li>Highlight the offending phrase.</li>\n<li>Suggest the compliant replacement inline.</li>\n<li>Do NOT publish until clean.</li>\n</ol>\n<p>VALIDATION: A red-team test fixture (<code>tests/fair_housing_redteam.txt</code>) contains 20 sample listings with known violations. The gate must catch ≥ 19 of 20.</p>\n<p>FALLBACK: If a phrase is ambiguous (could be discriminatory in some contexts, not others), flag with a yellow \"review required\" rather than auto-rewrite.</p>\n<h1>============================================================\n=== PHASE 2: FEATURE EXTRACTION &amp; STRUCTURING ===</h1>\n<p>Take the input facts and organize into a structured features dictionary:</p>\n<pre><code>hero_feature: \"Renovated chef's kitchen with quartz waterfall island\"\nsecondary_features:\n  - \"Vaulted ceilings throughout main level\"\n  - \"Primary suite with walk-in closet and spa bath\"\n  - \"Fenced backyard with covered patio\"\nneighborhood:\n  - \"1/2 mile to Whole Foods\"\n  - \"Walk Score 84\"\n  - \"Highly rated public schools (avoid naming specific schools in copy — fair housing risk)\"\nfinancial_highlights:\n  - \"$8,400/year property taxes\"\n  - \"$320 HOA covers exterior + landscaping\"\nrecent_updates:\n  - \"New roof 2024\"\n  - \"HVAC replaced 2023\"\n</code></pre>\n<p>The HERO feature gets prime placement in every length variant. Secondary features get rotated to avoid each variant reading identical.</p>\n<p>VALIDATION: Hero feature appears in tagline, MLS-short, and MLS-long. Secondary features rotate. No feature appears more than twice in the same variant.</p>\n<h1>============================================================\n=== PHASE 3: GENERATE FIVE LENGTH VARIANTS ===</h1>\n<p>Generate each variant with strict character/word limits:</p>\n<h3>Variant 1: Tagline (≤ 80 characters)</h3>\n<p>One sentence. Hero feature + neighborhood signal.\nExample: \"Renovated 4-bed with chef's kitchen in walkable Westside neighborhood.\"</p>\n<h3>Variant 2: MLS Short Remarks (≤ 250 characters)</h3>\n<p>The \"search results card\" copy. Hook + 3 features + call to action.\nExample: \"Light-filled 4-bed/3-bath with chef's kitchen, vaulted ceilings, and fenced yard. New roof and HVAC. Two-car garage. Move-in ready. See it before it's gone.\"</p>\n<h3>Variant 3: MLS Long Remarks (≤ 4000 characters)</h3>\n<p>Full property description. Structure:</p>\n<ol>\n<li>Hook (1-2 sentences)</li>\n<li>Exterior / curb appeal (1 paragraph)</li>\n<li>Main living areas (1-2 paragraphs)</li>\n<li>Kitchen (1 paragraph — usually the hero in residential)</li>\n<li>Primary suite (1 paragraph)</li>\n<li>Additional bedrooms / baths (1 paragraph)</li>\n<li>Outdoor / lot (1 paragraph)</li>\n<li>Mechanical / updates / inclusions (1 paragraph)</li>\n<li>Closing nudge (1 sentence)</li>\n</ol>\n<h3>Variant 4: Marketing Description (600-800 words)</h3>\n<p>For the agent's website, brochures, social posts (long form). Same structure as Variant 3 plus:</p>\n<ul>\n<li>Add neighborhood narrative (cafes, parks, retail — no schools by name)</li>\n<li>Add lifestyle framing (\"morning coffee on the patio\", \"evening sunsets\")</li>\n<li>Stay objective on neighborhood feel — describe places, not people</li>\n</ul>\n<h3>Variant 5: Social Caption (≤ 200 characters)</h3>\n<p>Instagram/Facebook ready. Hook + 1 feature + 3 hashtags.\nExample: \"Renovated kitchen, dreamy primary suite, fully fenced yard. Open house Saturday 1-3. #JustListed #YourCityRealEstate #DreamHome\"</p>\n<p>VALIDATION: Each variant under its character limit. No banned phrases from Phase 1. Each variant has the hero feature.</p>\n<p>FALLBACK: If 4000-char MLS Long Remarks runs short on details (sparse input), do NOT pad — output what's substantive and note \"Add: ___\" placeholders.</p>\n<h1>============================================================\n=== PHASE 4: SCHEMA.ORG JSON-LD ===</h1>\n<p>Generate <code>schema.json</code> with the <code>RealEstateListing</code> schema for SEO + AEO (Answer Engine Optimization — surfaces in Google AI Overviews, ChatGPT real estate queries, Perplexity).</p>\n<pre><code>{\n  \"@context\": \"https://schema.org\",\n  \"@type\": \"RealEstateListing\",\n  \"name\": \"4-Bedroom Home with Chef's Kitchen\",\n  \"url\": \"{listing_url}\",\n  \"datePosted\": \"{ISO_date}\",\n  \"address\": {\n    \"@type\": \"PostalAddress\",\n    \"streetAddress\": \"...\",\n    \"addressLocality\": \"...\",\n    \"addressRegion\": \"...\",\n    \"postalCode\": \"...\",\n    \"addressCountry\": \"US\"\n  },\n  \"geo\": { \"@type\": \"GeoCoordinates\", \"latitude\": 0, \"longitude\": 0 },\n  \"offers\": {\n    \"@type\": \"Offer\",\n    \"price\": 0,\n    \"priceCurrency\": \"USD\",\n    \"availability\": \"https://schema.org/InStock\"\n  },\n  \"numberOfBedrooms\": 4,\n  \"numberOfBathroomsTotal\": 3,\n  \"floorSize\": { \"@type\": \"QuantitativeValue\", \"value\": 0, \"unitCode\": \"FTK\" },\n  \"yearBuilt\": 0,\n  \"description\": \"{MLS_long_remarks}\"\n}\n</code></pre>\n<p>VALIDATION: JSON-LD passes Google's Rich Results Test (no required-field errors). Lat/long, if missing, are flagged as TODO (don't fabricate coordinates).</p>\n<h1>============================================================\n=== PHASE 5: OUTPUT PACKAGE ===</h1>\n<p>Final deliverable directory:</p>\n<pre><code>listing-{address-slug}/\n├── README.md              # how to publish where\n├── tagline.txt\n├── mls_short.txt          # paste into MLS public remarks (short)\n├── mls_long.txt           # paste into MLS public remarks (long)\n├── marketing.md           # paste into agent website / brochure\n├── social.txt             # Instagram / Facebook caption\n├── schema.json            # add to listing page &lt;script type=\"application/ld+json\"&gt;\n└── compliance_report.md   # what was checked, anything flagged\n</code></pre>\n<p>The README explains exactly where each file goes and why.</p>\n<h1>============================================================\n=== SELF-REVIEW ===</h1>\n<p>Score 1–5:</p>\n<ul>\n<li><strong>Complete</strong>: All 5 variants generated + JSON-LD + compliance report?</li>\n<li><strong>Robust</strong>: Compliance gate caught all violations? Character limits respected? Hero feature consistent?</li>\n<li><strong>Clean</strong>: No exclamation point overuse, no clichés (\"must see!\", \"won't last!\", \"priced to sell\"), no all-caps emphasis?</li>\n<li><strong>Fair-housing-safe</strong>: Re-scan final output with the banned-pattern list — zero hits required, not \"low\".</li>\n</ul>\n<p>If any &lt; 4:</p>\n<ul>\n<li>Most common gap: clichés sneaking into MLS-long. Replace with specific factual details.</li>\n<li>Second most common: subtle familial-status language. Re-scan.</li>\n</ul>\n<h1>============================================================\n=== LEARNINGS CAPTURE ===</h1>\n<p>Append to <code>~/.claude/skills/mls-listing-craft/LEARNINGS.md</code>:</p>\n<h2></h2>\n<ul>\n<li><strong>What worked:</strong> </li>\n<li><strong>What was awkward:</strong> &lt;retry / rewrite needed&gt;</li>\n<li><strong>Suggested patch:</strong> </li>\n<li><strong>Verdict:</strong> [Smooth / Minor friction / Major friction]</li>\n</ul>\n<h1>============================================================\n=== STRICT RULES ===</h1>\n<ul>\n<li>Never bypass the fair housing gate. A discriminatory listing is a license risk for the agent, not a stylistic preference.</li>\n<li>Never exceed character limits.

If the input doesn't include a fact, omit it — don't infer.</li>\n<li>Never name specific schools by name in copy (NAR guidance — implies a \"good schools = wealthy area = race-coded\" loop).</li>\n<li>Never use the word \"master\" for the bedroom/bathroom. Use \"primary\".</li>\n<li>Never end every variant with \"Don't miss out!\" or similar.
