Plugin Communication Bridge

Task 005: Plugin Communication Bridge

Overview

Extend query routing for AI type queries and implement message transformation between API and plugin formats. This creates the communication bridge that enables seamless interaction between the HTTP API layer and AI plugins.

Objectives

• Extend existing query routing to handle AI-specific query types
• Implement message transformation between API and plugin formats
• Create communication protocols for AI plugin interaction
• Ensure proper message serialization and deserialization
• Establish reliable plugin communication patterns

Technical Requirements

Query Routing Extension

• Extend current query routing logic to identify AI query types
• Implement routing rules for different AI operations (generate, validate, status)
• Add support for AI query context and metadata
• Ensure backward compatibility with existing routing

Message Transformation

• Implement bidirectional message transformation:
  • API request format → Plugin message format
  • Plugin response format → API response format
• Handle message field mapping and validation
• Implement proper error message transformation
• Support different AI plugin communication protocols

Plugin Communication Protocol

• Establish communication patterns for AI plugins
• Implement plugin discovery and registration
• Handle plugin lifecycle management (connect, disconnect, health checks)
• Implement timeout and retry logic for plugin communications
• Add support for asynchronous AI operations

Integration Layer

• Create abstraction layer for different AI plugin types
• Implement plugin adapter pattern for extensibility
• Add plugin-specific configuration management
• Ensure proper resource management and cleanup

Acceptance Criteria

• Query routing correctly identifies and routes AI queries
• Message transformation works bidirectionally without data loss
• Plugin communication protocols are stable and reliable
• Multiple AI plugins can be supported simultaneously
• Error handling covers all communication failure scenarios
• Plugin discovery and registration work automatically
• Performance requirements met for message transformation
• Integration tests verify end-to-end communication

Dependencies

This task depends on:

• Task 003: Proto interface validation must be complete for stable message formats

Conflicts

This task works alongside Task 004 but may require coordination on:

• Message format definitions
• Error handling patterns
• Plugin interface specifications

Implementation Notes

This bridge implementation should:

• Maintain loose coupling between API and plugin layers
• Support multiple AI plugin types and vendors
• Handle plugin failures gracefully with fallback mechanisms
• Implement proper logging for communication debugging
• Consider security implications of plugin communication

The communication bridge serves as:

• Protocol translator between different message formats
• Router for distributing queries to appropriate plugins
• Coordinator for complex AI operations requiring multiple plugins
• Monitor for plugin health and performance

Files to Create/Update

• Query routing extension files
• Message transformation utilities
• Plugin communication protocol implementations
• Plugin adapter interfaces
• Communication layer tests
• Plugin integration documentation

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