Architecture for Tabnine Agent

Agent Architecture

High-Level Architecture

Core Components

1. Agent Core

The heart of the agent system, the Agent Core is responsible for:

  • Request Processing: Parsing and understanding user requests

  • Execution Orchestration: Managing multi-step workflows

  • Context Management: Maintaining conversation and code context

  • Response Generation: Formatting and delivering results

Additional key features include the following:

  • Node.js runtime for flexibility and tool integration

  • Asynchronous processing for responsive interactions

  • Memory management for conversation continuity

  • Error handling

  • Recovery mechanisms

2. Prompt Engine

Responsible for intelligent context assembly and prompt construction:

  • Context Gathering: Collecting relevant code, documentation, and history

  • Prompt Optimization: Tailoring prompts for specific models

  • Token Management: Optimizing context within model limits

  • Dynamic Assembly: Real-time context selection based on request

3. Tool Manager

Handles all external tool interactions:

  • MCP Integration: Managing Model Context Protocol servers

  • Native Tools: Built-in Tabnine capabilities

  • API Orchestration: Coordinating multiple tool calls

  • Permission Management: Enforcing tool access controls

4. Workflow Engine

Manages complex, multi-step agent operations:

  • Planning: Breaking down complex requests into steps

  • Execution: Running steps in sequence or parallel

  • Monitoring: Tracking progress and handling failures

  • Adaptation: Adjusting plans based on intermediate results
