Tool Schema Architecture

Tool schemas define parameters and outputs used by the model to select and invoke capabilities.

WHY IT MATTERS

Ambiguous or over-broad schemas increase incorrect tool use and validation complexity.

ENTERPRISE EXAMPLE

ARCHITECTURE DECISION

Can the tool contract reject unexpected parameters before execution?

REMEMBERNarrow schemas reduce both model confusion and attack surface.
