Codart AI: Multi-Agent System Architecture

Technical Implementation and System Design

📅 May 2025 ⏱️ 10 min read 🏷️ AI, Software Engineering, Multi-Agent Systems

System Overview

Codart AI implements a multi-agent system designed for automated software engineering tasks. The system combines specialized agents with advanced code analysis tools to process, understand, and modify codebases with high precision and efficiency.

Core Architecture

System Components and Integration

Planner Agent

Core reasoning engine powered by Claude 3.5 Sonnet. Implements issue analysis, requirement parsing, and plan generation. Uses semantic search for pattern matching and solution optimization.

File Agent

Code analysis engine with AST parsing capabilities. Implements semantic indexing using Whoosh for efficient file search and feature implementation detection, maintains code context through reference tracking, and performs validation through static analysis.

Implementation Planner

State management and coordination system. Tracks file modifications, maintains change history, and ensures implementation consistency through validation checks.

Developer Agent

Code modification engine with syntax validation. Implements changes through Python's REPL, maintains code quality through autopep8, and performs self-review through static analysis.

System Workflow

  1. Analysis Phase

    Planner Agent processes GitHub issues through semantic analysis, extracts requirements, and generates implementation specifications. Uses Whoosh for efficient file search to identify potential implementation locations.

  2. Planning Phase

    Implementation Planner processes specifications, identifies affected files through AST analysis, and generates modification plans with dependency tracking.

  3. Implementation Phase

    Developer Agent executes modifications with syntax validation, applies formatting rules, and maintains code quality through static analysis tools.

  4. Validation Phase

    System performs comprehensive validation including syntax checking, static analysis, and test verification. Generates detailed modification reports.
