Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢resolve_jurisdiction(ship_to)
Resolve a ship-to (e.g. 'US-CA', 'CA-ON', 'MX', 'EU-DE', 'UK', 'KR', 'JP', 'SG', 'CH') to the gate's jurisdiction (US · CA · MX · EU · UK · KR · JP · SG · CH; UK is the jurisdiction name; the ISO 3166-1 code is accepted as input, machine fields carry the ISO code and jurisdiction_label carries UK), the EU member and any state, provincial or cantonal overlay.

}🟢resolve_actor(actor_class, credential)
Resolve the actor class and channel. Classes: authorized_trading_partner and its members (manufacturer · repackager · wholesale_distributor · dispenser · third_party_logistics_provider; cosmetic_responsible_person · nhp_licence_holder on the non-drug pathways), prescriber, the referral classes patient and public, and agent (inherits the class of the credential it presents; none returns DENY_UNLICENSED_AGENT).

Returns a frozen reason code, the rule-set version, the source page and a decision_id for the downstream tools.
