Configuration

Architecture

Service Layer

• AuthService - Handles authentication, token management, session persistence
• PeerService - Manages peer discovery, connections, and real-time communication
• AiValidatorService - Provides AI-powered validation, sanitization, and enhancement
• MessageRouterService - Routes messages between peers with validation pipeline

Protocol

The extension uses a versioned protocol for peer communication:

• Handshake - Connection establishment with capability negotiation
• Messages - Chat, code, AI prompts, and responses
• Presence - Online status and typing indicators

Security

• JWT authentication with automatic refresh
• Secrets and PII detection in messages
• Input sanitization and injection prevention
• Secure storage using VS Code's SecretStorage API

Roadmap
