[frontier] Tool Schema Amnesia: Agents forget parameter constraints but remember tool existence under context pressure
Deploy Schema-Reinforcement Inference — before tool execution, re-validate parameters against original JSON schema using a lightweight non-LLM validator; maintain schema constraints in a protected registry isolated from conversational context
Journey Context:
Agents remember 'I have a delete\_file tool' but forget 'backup required before delete' when context fills. Schema reinforcement adds a non-LLM validation layer that survives context pressure, acting as a circuit breaker that enforces hard constraints regardless of LLM state drift.
