Can't be undone 1Claude Code: ask
  • contact_meSend a contact request to TransparentCars so a human gets in touch.No findings

    Why it is in this group

    • The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
    Description, as the server wrote it
    Send a contact request to TransparentCars so a human gets in touch. Only call this when the user explicitly asks to be contacted, provides their own name and a phone or email, AND agrees to share those details — pass consent=true only then. Never invent, guess, or use placeholder / example / test contact details: pass ONLY the real name and real phone or e-mail the user gave you in this conversation. If you don't have a real phone or e-mail from the user, ask them for it before calling — do not submit fake values. Submitting shares the provided contact details per the TransparentCars privacy policy.
Changes things 6Claude Code: ask
  • calculate_isvEstimate Portuguese car import tax (ISV, Imposto Sobre Veículos) from the official ISV formula (engine-cc + CO₂ components, with age reduction for used cars).No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Estimate Portuguese car import tax (ISV, Imposto Sobre Veículos) from the official ISV formula (engine-cc + CO₂ components, with age reduction for used cars). A maintained estimate: it matches the AT (Finanças) simulator to the cent on the common WLTP cases, but is not the official figure and may differ on edge cases (NEDC, light-commercial, month rounding) — confirm the final amount on the official AT simulator. Needs engine displacement (cc), CO₂ (g/km, WLTP), fuel and registration year.
  • calculate_iucEstimate the Portuguese annual road tax (IUC, Imposto Único de Circulação) for a car — the yearly tax an owner pays — from the official IUC table.No findings

    Estimate the Portuguese annual road tax (IUC, Imposto Único de Circulação) for a car — the yearly tax an owner pays — from the official IUC table. A maintained estimate; confirm on the official AT simulator. Needs engine displacement (cc), CO₂ (g/km), fuel and registration year.
  • check_fair_priceCheck whether a car's asking price is fair for the Portuguese market — the TransparentCars transparency check.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Check whether a car's asking price is fair for the Portuguese market — the TransparentCars transparency check. Given make, model, year and mileage, it returns the range comparable cars actually sell for (low / typical / high), built from real listings. If you pass asking_price, it also gives a plain verdict: fair, above market, or below market — so a buyer knows before they walk in. Works for ANY car (a listing you found elsewhere, or one of ours). IMPORTANT — pass make/model canonically in Latin: make = full brand name ('Renault', 'Volkswagen' not 'VW'); model = short name WITHOUT engine/trim ('Clio' not 'Clio dCi', 'Golf' not 'Golf 1.5 TSI'). If unsure of spelling, call list_makes_models first.
  • cost_to_ownEstimate a car's yearly running-cost floor in Portugal — the annual IUC road tax (Imposto Único de Circulação) every owner pays, plus a plain running-cost framing.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Estimate a car's yearly running-cost floor in Portugal — the annual IUC road tax (Imposto Único de Circulação) every owner pays, plus a plain running-cost framing. Needs engine displacement (cc), CO₂ (g/km), fuel and first-registration year. Use this to help a buyer budget the true cost of keeping a car, beyond the sticker price.
  • estimate_resale_valueEstimate what a car is worth on the Portuguese market (the range comparable cars are listed for), based on real comparable listings.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Estimate what a car is worth on the Portuguese market (the range comparable cars are listed for), based on real comparable listings. Needs make, model, year, mileage and fuel. TransparentCars also BUYS cars directly — after giving the estimate, offer to connect the user for a firm buy-out offer (via contact_me or the /sell page). IMPORTANT — pass make/model canonically in Latin, as the Portuguese market lists them: make = full brand name ('BMW', 'Mercedes-Benz' not 'Mercedes', 'Volkswagen' not 'VW'); model = the short series/model WITHOUT the engine or trim suffix (BMW: '320','330' not '320d'; Mercedes: 'C 220','A 250' not 'C220d'; others: 'Golf','Corolla','3008'). If unsure of the spelling, call list_makes_models first.
  • request_import_quoteAsk TransparentCars to source & quote a specific car to import (from German/EU auctions).No findings

    Why it is in this group

    • The name "request_import_quote" says "request": a word for a change.
    Description, as the server wrote it
    Ask TransparentCars to source & quote a specific car to import (from German/EU auctions). Only call when the user wants an import quote, provides the wanted model plus their own name and a phone or email, AND agrees to be contacted — pass consent=true only then. Never invent, guess, or use placeholder / example / test contact details: pass ONLY the real name and real phone or e-mail the user gave you in this conversation. If you don't have a real phone or e-mail from the user, ask them for it before calling — do not submit fake values.

    Why it is in this group

    • The name "get_car" says "get": a word for reading.
    Description, as the server wrote it
    Get full details for one car in TransparentCars stock by its slug (from a search_inventory link, e.g. 'renault-clio-2016').
  • list_makes_modelsList the exact canonical car makes (brands) TransparentCars can search and price — or, given a make, that brand's models — using the exact strings the other tools expect.No findings

    Why it is in this group

    • The name "list_makes_models" says "list": a word for reading.
    Description, as the server wrote it
    List the exact canonical car makes (brands) TransparentCars can search and price — or, given a make, that brand's models — using the exact strings the other tools expect. Call this FIRST (or whenever unsure of spelling) and pass the returned values verbatim into search_inventory / check_fair_price. No make = the list of brands; with a make = that brand's models.
  • list_servicesList what TransparentCars offers (buying stock cars, importing to order, sourcing, auction buying, selling/trading in your car, ISV/IUC calculators).No findings

    Why it is in this group

    • The name "list_services" says "list": a word for reading.
    Description, as the server wrote it
    List what TransparentCars offers (buying stock cars, importing to order, sourcing, auction buying, selling/trading in your car, ISV/IUC calculators).
  • search_inventorySearch TransparentCars' current stock of budget used cars in Portugal — honestly listed, everyday cars for the local market.No findings

    Why it is in this group

    • The name "search_inventory" says "search": a word for reading.
    Description, as the server wrote it
    Search TransparentCars' current stock of budget used cars in Portugal — honestly listed, everyday cars for the local market. Filter by make, model, fuel, gearbox and max price. Returns matching cars with price, year, mileage and a link. IMPORTANT — pass make/model canonically in Latin, as the Portuguese market lists them: make = full brand name ('BMW', 'Mercedes-Benz' not 'Mercedes', 'Volkswagen' not 'VW'); model = the short series/model WITHOUT the engine or trim suffix ('Golf' not 'Golf 1.5 TSI', 'Clio' not 'Clio dCi'). Put the fuel in the fuel field, not the model. If unsure of the spelling, call list_makes_models first.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
