How claude-code Works: Architecture & Code

Project Overview

Claude Code is an agentic coding tool designed to operate within a developer's terminal or IDE, providing an intelligent assistant that understands codebase context and facilitates various development tasks. It extends its functionality through a robust plugin architecture, allowing it to execute routine coding tasks, explain complex code, manage Git workflows, and perform automated code reviews by orchestrating specialized AI agents and commands. Users interact with it through natural language commands, enabling a conversational approach to coding.

Key Modules & Components

Plugin Management and Orchestration: Manages the discovery, loading, and execution of plugins, providing the core functionality for extending Claude Code's capabilities. This includes managing plugin metadata, lifecycle hooks, and the plugin marketplace.
Pull Request Review Automation: Automates the process of reviewing pull requests by orchestrating a suite of specialized AI agents that analyze code changes from multiple perspectives and provide comprehensive feedback.
Feature Development Assistance: Provides guidance and assistance throughout the feature development lifecycle, from codebase exploration and architectural design to implementation and code review.
Git Workflow Automation: Streamlines Git workflows by providing commands for common operations such as committing changes, pushing to remote repositories, and creating pull requests.
Automated Issue Deduplication: Automatically identifies and closes duplicate GitHub issues to improve issue tracker hygiene and reduce developer overhead.
Real-time Security Guidance: Provides developers with real-time security reminders and warnings during code editing to prevent common vulnerabilities such as command injection and XSS.
