        "longDescription": "Greca House is an independent real-estate brokerage in central Athens. It continues the independent brokerage activity established by founder and owner Iryna Rondyak in Athens in 2008. This plugin lets you work with its public listings and research inside ChatGPT.\n\nWhat it does:\n- Search Greca House's current listings in Greece for sale or rent: apartments, villas, maisonettes, buildings, land and commercial property in Athens, Attica, the Peloponnese, the islands and elsewhere. Filter by area, budget, size, an exact number or range of bedrooms, listings with a 3D model, 360\u00b0 tour or video, and listings Greca House classifies under a Golden Visa property route.\n- Open one listing: description, facts, features, photos, media links and the page on grecahouse.com.\n- Compare asking prices per square metre between Athens neighbourhoods and regions, and see what a budget lists for, from Greca House's dated research snapshot (with sample sizes and method).\n- Estimate the costs of buying a resale property in Greece on top of the price: transfer tax, municipal surcharge, Cadastre registration and the notary's scale fee. Lawyer, engineer and agency fees are added only from amounts you enter from written quotes.\n\nLimits:\n- Results cover Greca House's own listings, not every property in Greece. Prices are asking prices, not sale prices.\n- Research figures come from dated snapshots of those listings' asking prices: not forecasts, trends, yields or whole-market claims.\n- A Golden Visa classification is Greca House's office classification of the property route only. It is not recalculated from price or size, does not decide an applicant's eligibility and is not legal advice.\n- Cost estimates are not legal or tax advice; new-build VAT and exemptions are not modelled.\n- Read-only: the plugin does not contact the agency, book viewings or store what you ask. Use the listing or contact links to reach Greca House.",

The skill description now names each use: searching current listings, opening a listing's details and media, dated asking-price research by area or budget, buying costs and the Golden Visa property-route classification. Price caps are stated as inclusive: max_price_eur=300000 includes listings priced exactly \u20ac300,000, so a request for listings under \u20ac300,000 uses max_price_eur=299999 or says how many are priced exactly at the cap. Counts: total_matches is reported as the count for one query only, never a page size or a sum of pages; only non-overlapping region totals with identical filters are added; each figure names the regions or area it covers and what it leaves out; contradictory figures are rechecked instead of reported. Results beyond the first page are fetched with offset, and a list is not called complete unless every page was checked. A research area with too few listings is reported as not covered, with its containing region's figure given only as that region's. Golden Visa classifications are reported exactly as each listing returns them, and only about listings actually shown. Rankings such as \"best value\" are given only with a stated, objective rule and the field each listing was ranked on. An announced tax change that is not law yet is never applied.",
