ReferralCodeLink

get_referral_code and search_referral_codes can both look up a company by name, and list_all_referral_codes returns a superset of what list_business_referral_codes and list_featured_referral_codes provide, so an agent may hesitate between them. The descriptions do clarify the business-vs-featured split and the exact-lookup vs query distinction, which keeps it workable but not clean.

All names follow a strict verb_noun snake_case pattern (get_, list_, list_, list_, search_) with the consistent object 'referral_codes'. The convention is predictable and readable throughout.

Five tools is well-scoped for a referral-code directory: one lookup, one search, and three listing variants. Each tool maps to a plausible browse/filter use case without bloat.

The read-only surface covers direct lookup, keyword search, and segmented listing, which is the full lifecycle for curated reference data (no write operations are expected). Minor gaps like category enumeration or pagination hints exist but are easy to work around.
