Proto Interface Design

Task 001: Proto Interface Design

Overview

Implement dual proto extensions in both server.proto and loader.proto to establish the foundation for AI-powered SQL generation. This critical path task must be completed before any other AI extension work can begin.

Objectives

• Add AI-specific message types to both proto files
• Implement proper field numbering for backward compatibility
• Design service interfaces for AI query handling
• Ensure consistent message structure across both proto files

Technical Requirements

Server.proto Extensions

• Extend existing HTTP API messages for AI query support
• Add AI-specific request/response types
• Implement proper gRPC service definitions
• Use field numbers 10+ for new AI fields

Loader.proto Extensions

• Extend plugin communication messages for AI support
• Add AI-specific plugin lifecycle messages
• Implement AI query routing messages
• Maintain backward compatibility with existing plugins

Acceptance Criteria

• Both proto files compile without errors
• AI message types are properly defined
• Field numbering follows backward compatibility rules
• Service interfaces are complete and consistent
• No breaking changes to existing message types

Implementation Notes

This is a critical path task that blocks all subsequent AI extension development. The proto interfaces designed here will be the foundation for:

• Code generation in task 002
• Interface validation in task 003
• All future AI plugin development

Files to Modify

• pkg/server/server.proto
• pkg/testing/remote/loader.proto

🔄 Reopening - no actual code implementation was completed. Only documentation was updated. Need to implement actual proto extensions, HTTP API, frontend components, and testing.
