The capability facade & tokens

Statically listing every tool to a model inflates input tokens on every turn. The facade instead exposes gateway.find(query) — returning matching tools with their full, invocable schemas — and gateway.find_and_invoke, which selects and dispatches in the same round trip.

Whether that saves tokens depends on the workload, so the facade measures it and recommends static exposure when it does not win. A large catalog with a narrow per-turn need is where it shines (> 50% reduction); a handful of tools is not. See the token report and portcullis translate ... --find.
