# Agent System Architecture

The Dexorder AI platform uses a sophisticated agent harness that orchestrates between user interactions, LLM models, and user-specific tools.

## Core Components

### Gateway
Multi-channel gateway supporting:
- WebSocket connections for web/mobile
- Telegram integration
- Real-time event streaming

### Agent Harness
Stateless orchestrator that:
1. Fetches context from user's MCP server
2. Routes to appropriate LLM model based on license
3. Calls LLM with embedded context
4. Routes tool calls to user's MCP or platform tools
5. Saves conversation history back to MCP

### Memory Architecture
Three-tier storage system:
- **Redis**: Hot state for active sessions and checkpoints
- **Qdrant**: Vector search for RAG and semantic memory
- **Iceberg**: Cold storage for durable conversations and analytics

### User Context
Every interaction includes:
- User ID and license information
- Active channel (websocket, telegram, etc.)
- Channel capabilities (markdown, images, buttons)
- Conversation history
- Relevant memories from RAG
- Workspace state

## Skills vs Subagents

### Skills
Self-contained capabilities for specific tasks:
- Market analysis
- Strategy validation
- Indicator development
- Defined in markdown + TypeScript
- Use when task is well-defined and scoped

### Subagents
Specialized agents with dedicated memory:
- Code reviewer with review guidelines
- Risk analyzer with risk models
- Multi-file knowledge base
- Custom system prompts
- Use when domain expertise is needed

## Global vs User Memory

### Global Memory (user_id="0")
Platform-wide knowledge available to all users:
- Trading concepts and terminology
- Platform capabilities
- Indicator documentation
- Strategy patterns
- Best practices

### User Memory
Personal context specific to each user:
- Conversation history
- Preferences and trading style
- Custom indicators and strategies
- Workspace state

All RAG queries automatically search both global and user-specific memories.
