German SIM-only and data tariffs of about 50 providers, read daily, ranked by 24-month cost.
Scored across 3 tools
Each tool targets a clearly distinct action on a distinct resource set: search_tariffs finds/compares, get_tariff fetches one by id, list_providers enumerates providers/slugs. The descriptions even state the handoff (search results contain the id, provider slugs feed the search filter), so an agent can chain them without guessing.
All three names follow the same snake_case verb_noun pattern (get_/list_/search_ + noun), with the verb accurately signalling cardinality and intent. No mixed conventions or vague verbs.
Three tools is well-scoped for a read-only tariff comparison catalog: one discovery/search entry point, one detail lookup, one metadata listing. Nothing redundant and nothing obviously missing at the count level.
Search + detail + provider listing covers the realistic read-only workflow (find, compare, inspect), and the domain is explicitly bounded (Germany, SIM-only). Minor gaps: no dedicated way to enumerate networks/terms independently, and no lightweight compare tool, though these are derivable via search filters and get_tariff.
Returns one tariff in full: all costs, data, network, speed, term, a one-sentence summary and its price history. Use it when the user asks about one specific tariff, given by the id that tariff search results contain.
Inputs: id (required), language.
