# Appendix: TIE Response Protocol

The response wire format used by TIECloudApp.

## Minimal response protocol

Minimal response protocol A minimal protocol that a Shadow Tunneling implements to stand in for The Inference Engine in the VRE. Over the course of a response, TIECloudApp streams a sequence of Response messages, each carrying one of the cases in the responses oneof. A typical response streams generated tokens as a series of content messages; when the model invokes a tool, it emits a call message describing the tool and its arguments. The server sends an inference_complete message once it finishes generating, and a final_response message closes the response. A shadow remote reproduces this flow by replaying the same message sequence. syntax = "proto3";

message Empty {}

message Response {   oneof responses {     ResponseContent content = 1;     FinalResponse final_response = 2;     Empty inference_complete = 5;     ToolCall call = 8;   } }

message ResponseContent {     string tokens = 1; }

message FinalResponse {     string sentence = 1; }

message ToolCall {     string call_id = 1;     ToolCallContent content = 2; }

message ToolCallContent {     oneof Oneof_ToolCallContent {         ToolCallFunction function = 1;     } }

message ToolCallFunction {     string tool_name = 1;     string arguments = 2; //json string }
