ToolThrift

Agent sessions can spend substantial context on tool schemas and verbose result envelopes before useful work begins. ToolThrift sits in front of authorized tool servers, serves a compatibility-aware slim manifest, exposes additional tools through explicit discovery and offers compact result views with raw fallback. The supplied research shows at least four open implementations already providing discovery, schema compression, budget enforcement or usage tracking. A large federation gateway is also adjacent. The remaining hypothesis is hosted operation, team governance, persistent per-session state and metered analytics—not an unoccupied mechanism. Schema or payload rewriting can remove meaning, change types, hide warnings or break clients, so every transform needs a version, equivalence tests and an immediate raw path. Frequency is not importance: a rarely used recovery or deletion tool must not be demoted solely by observed calls. The gateway can see sensitive arguments, results and credentials; minimization, encryption, scoped identity, retention and zero-content analytics must be designed before hosting. Baseline, eligible bytes or tokens, transformed representation, client acceptance, task outcome, provider charge and realized financial saving remain separate. Success is lower measured context overhead without increased tool-selection error or result misunderstanding—not a guaranteed percentage, model quality gain or savings-based invoice claim.
