output_schema |
google.protobuf.struct_pb2.Struct
Optional. A JSON Schema object defining the expected structure of the tool's output. |
annotations |
google.protobuf.struct_pb2.Struct
Optional key-value object that allows developers to provide additional information regarding tool properties, behavior, and usage best practices. Annotations or tags to facilitate semantic search across tools ("semantic tags") are not in the MVP scope. When implemented, the first set of supported annotations will likely be the standard, predefined annotations from the open-source MCP spec. These include: - title: A human-readable title for the tool, useful for UI display. - readOnlyHint: If true, indicates the tool does not modify its environment. - destructiveHint: If true, the tool may perform destructive updates (only meaningful when readOnlyHint is false). - idempotentHint: If true, calling the tool repeatedly with the same arguments has no additional effect (only meaningful when readOnlyHint is false). - openWorldHint: If true, the tool may interact with an "open world" of external entities. |
