assess_offer
ChatGPTAssess whether a single monthly offer is a good deal, using Mivodo's benchmark: returns the offer's price_score (0-5), its effective rate and effective factor, and the range of comparable offers for the same model/segment. Use this when the user asks "is this offer good/bad?" about a specific offer id from a search result.
compare_offers
ChatGPTUse this when the user wants to compare two or three Mivodo offers. Refreshes public active offers and compares gross costs, exact contract terms, consumption and listed services. Pass the condition_id, duration_in_months and km_per_year from search results to preserve the selected contract. Unavailable contracts are reported without substituting another. Missing fees/services are unknown, not zero. price_score is an offer-level benchmark, not an assessment of the selected contract. Purchase and monthly prices must not be ranked together.
