• Calculate mortgage ratios · Read-only action

  Use this when the user wants a quick mortgage viability or affordability check for Spain. Prefer this over a full mortgage simulation when the user is asking whether they can afford a property, whether their savings are enough, or only has partial affordability data. It returns LTC, LTV, and DTI from the property amount, savings, income, expenses, term, and interest rate provided. Never invent missing values; ask for the missing required inputs instead. Do not replace this tool with your own LTC, LTV, or DTI calculations; if inputs are missing, ask for them and then call the tool. Do not use this for a final monthly-payment scenario, purchase-tax estimate, reference-index lookup, or documented product or policy question.

• Calculate purchase taxes · Read-only action

  Use this when the user wants Spanish property purchase taxes or needs to understand the extra cash required for transaction taxes. Prefer this over a full mortgage simulation when the user is asking only about transaction costs or needs taxes before defining the mortgage scenario. It estimates taxes from the property amount, autonomous community, and whether the property is a new build. Never invent the community, property amount, or new-build status; ask for any missing required values. Do not replace this tool with your own tax estimate; if inputs are missing, ask for them and then call the tool. Do not use this for monthly-payment estimates, affordability ratios, reference-index lookups, or general explanatory questions that should use documented knowledge.

• Get mortgage reference index · Read-only action

  Use this when the user wants an official Spanish mortgage reference index such as Euribor or IRPH. Prefer this over a simulation when the user only needs the reference index value or wants to check the market index component of a variable mortgage. It fetches the latest available month or a specific month from the Bank of Spain. Do not use this to estimate payments, infer a lender spread, or assemble a mortgage offer from missing data. Do not use this for a mortgage simulation, purchase taxes, affordability ratios, or general mortgage guidance.

• Search knowledge base · Read-only action

  Use this when the user needs documented Trioteca knowledge instead of a calculation. Prefer this over calculation tools for policy, product, process, eligibility, or explanatory questions where no numeric result is needed. It retrieves grounded information for policy, product, or explanatory questions. Do not use this for mortgage simulations, affordability ratios, purchase taxes, or index lookups.

• Simulate mortgage · Read-only action

  Use this when the user explicitly wants a mortgage simulation, monthly payment estimate, or scenario comparison for Spain. It returns the estimated monthly payment, financed amount, total payment, total interest, taxes, and key affordability ratios. This is the preferred calculation flow when the user wants to know the monthly payment, total cost, or compare mortgage scenarios. If required inputs are missing, ask for those missing values and then call this tool. Do not replace this tool with your own mortgage math when the user is asking for a simulation. Prefer the affordability ratios tool instead when the user is asking for an early viability check, whether a property may be affordable, or whether their savings and income fit a target price. Never invent missing numeric, property, or mortgage values. Do not use this for documented Trioteca knowledge, standalone purchase-tax estimates, standalone index lookups, or general mortgage explanations that do not require a simulation.
