Claude Code

Claude Code is Anthropic's official AI-powered programming assistant and command line tool (CLI), designed for developers. With powerful code understanding capabilities and intelligent interaction, it helps developers efficiently complete various software development tasks including coding, debugging, refactoring, testing, and deployment.

Claude Code supports file editing, project searching, code completion, Git operations, package management execution, and extensibility through skills and MCP servers. It includes built-in practical skills like code review, commit & push, and PR generation for seamless integration with version control workflows. Developers can also create custom skills to automate their workflows.

Core Features

1. Intelligent Code Editing

Claude Code can read, create, and edit code files, supporting precise string replacement and batch modifications. It understands code structure, provides intelligent code suggestions and refactoring solutions, and automatically handles syntax errors and import issues.

2. Deep Project Exploration

Supports file pattern matching, content searching, and complex queries to quickly locate specific files or code snippets. It efficiently navigates large codebases, understands project architecture and dependencies, providing context support for further development.

3. Terminal Integration & Command Execution

Can directly execute command line instructions including package dependency installation, building and testing, Git operations, and deployment scripts. Supports background tasks for parallel execution, handles long-running processes, tracks output in real-time, and handles errors.

4. Git Collaboration Capabilities

Provides comprehensive Git workflow support including creating commits, pushing branches, and creating and reviewing PRs. Includes built-in safety mechanisms to ensure file changes align with remote state and avoid destructive operations.

5. Skills System

Includes built-in practical skills like pr-generator, prompt-rewriter for quickly generating PRs and optimizing prompts. Developers can also create custom skills to automate specific workflows.

6. MCP Server Support

Extends functionality through the Model Context Protocol (MCP) to flexibly integrate external services and tools.

7. LSP Intelligence

Integrates Language Server Protocol for features like code navigation, reference finding, hover information, and document symbols for deeper code understanding.
