Compared to a general-purpose agent receiving the same task, how much does scope isolation via JSON Schema role contracts reduce per-request token consumption?
Answer: 60–70%
Empirical measurements show that scope isolation via JSON Schema role contracts reduces per-request token consumption by 60–70% compared to general-purpose agents. The reduction comes from two sources: smaller input schemas (the agent only receives the fields relevant to its role, not the full coordinator state) and a more focused system prompt (role-specific instructions are shorter than general-purpose instructions that cover many task types). This compounding effect is significant at scale — a 60–70% cost reduction per call translates directly to agent cost budgets.
