# Claude Code

> Anthropic's frontier AI CLI. Claude Code combines Claude Opus 5 with native Computer Use, MCP support, and autonomous multi-file engineering.

Claude Code is a powerful AI-powered terminal tool that brings Claude's intelligence directly to your development workflow. Built specifically for developers, it offers agentic search capabilities, coordinated file changes, and seamless integration with your existing development environment.

## Overview

Claude Code represents a new paradigm in AI-assisted development. Unlike traditional AI coding assistants that work within IDEs, Claude Code operates directly in your terminal, providing deep codebase understanding and making coordinated changes across multiple files without manual context selection.

Claude Code is powered by Claude Opus 5—the same model used by Anthropic's researchers and engineers. It's designed to work where developers actually work: in the terminal, with their existing tools, and within their established workflows.

## Key Features

- **Computer Use (preview)**: Claude can browse the web and drive a GUI to research documentation and verify changes.
- **Model Context Protocol (MCP)**: Native hub for connecting to GitHub, Slack, Linear, and custom databases to provide deep business context.
- **Agentic Multi-File Editing**: Plans and executes complex, cross-dependency changes while maintaining codebase integrity.
- **Runs Where You Work**: The same agent is available in the terminal, on the web, as a desktop app, in VS Code and JetBrains IDEs, in Slack, and in CI via GitHub Actions and GitLab.
- **Autonomous Debugging**: Give Claude a stack trace, and it will run tests, inspect logs, and fix the root cause independently.
- **Secure File System Operations**: Permission modes and an interactive approval system for system-level actions.
- **Agentic Search**: Claude Code explores large repositories by reading and searching files on demand — there is no separate indexing step or vector database to maintain.
- **Subagents**: Claude Code can delegate scoped tasks to specialized subagents.

## How It Works

Claude Code uses advanced AI models to understand your codebase and provide intelligent assistance. The process involves:

1. **Codebase Analysis**: Automatically analyzes your entire project structure and context
2. **Pattern Recognition**: Identifies coding patterns and project-specific conventions
3. **Intelligent Search**: Performs agentic search to understand code relationships
4. **Coordinated Planning**: Plans changes across multiple files simultaneously
5. **Safe Execution**: Presents changes for approval before implementation

**Technical Architecture:**
- **Model**: Claude Opus 5 (with Sonnet 5 and Haiku 4.5 selectable)
- **MCP Support**: Native integration for Model Context Protocol.
- **Search Engine**: Agentic search for deep codebase understanding.
- **File Management**: Coordinated multi-file operations
- **IDE Integration**: Native VS Code extension and JetBrains support
- **Terminal Integration**: Seamless CLI experience
- **Safety**: Permission modes with explicit approval for file modifications
- **Performance**: Optimized for large codebases and complex projects

## Use Cases

### Code Understanding & Navigation
- **Onboarding**: Quickly understand new codebases and project structures
- **Code Exploration**: Navigate complex projects with intelligent search
- **Documentation**: Generate and update code documentation
- **Architecture Analysis**: Understand system design and component relationships

### Development Workflows
- **Feature Development**: Implement new features with coordinated changes
- **Bug Fixing**: Identify and fix issues across multiple files
- **Refactoring**: Safely refactor code while maintaining functionality
- **Code Modernization**: Update legacy code to modern standards

### Productivity Enhancement
- **Rapid Prototyping**: Quickly build and iterate on applications
- **Test Generation**: Create comprehensive test suites
- **Configuration Management**: Generate and update config files
- **API Integration**: Connect to external services and APIs

### Team Collaboration
- **Code Reviews**: Understand changes and provide intelligent feedback
- **Knowledge Transfer**: Share codebase knowledge with team members
- **Standards Enforcement**: Ensure consistent coding practices
- **Documentation**: Maintain up-to-date project documentation

## Pricing & Access

Claude Code requires a Claude subscription (Pro, Max, Team, or Enterprise), a Claude Console account, or access through a supported cloud provider. It is **not** included in the free Claude plan. All prices below are in **USD**, as published on [claude.com/pricing](https://www.claude.com/pricing).

### Free
- Chat on web, iOS, Android, and desktop — Claude Code is not included.

### Pro — $17/month billed annually ($200 up front), or $20/month billed monthly
- Includes Claude Code
- Includes Claude Cowork, Claude Design, and Claude Science
- Unlimited projects, access to Research, more Claude models

### Max — from $100/month
- Everything in Pro
- Choose 5x or 20x more usage than Pro
- Higher output limits, early access to advanced features, priority access at high traffic times

### Team — $20/seat/month annually ($25 monthly) for a standard seat; $100/seat/month annually ($125 monthly) for a premium seat

### API (Claude Console) — pay as you go
Per million tokens (MTok), input / output:
- **Fable 5**: $10 / $50
- **Opus 5**: $5 / $25
- **Sonnet 5**: $2 / $10, cache reads $0.20. Launched as introductory pricing through August 31, 2026; Anthropic made it the standard price and cancelled the planned rise to $3 / $15.

## Getting Started

### Step 1: Install Claude Code
Native install (recommended):

```bash
# macOS, Linux, WSL:
curl -fsSL https://claude.ai/install.sh | bash
```

```powershell
# Windows PowerShell:
irm https://claude.ai/install.ps1 | iex
```

Homebrew is also supported: `brew install --cask claude-code`.

### Step 2: Log In
1. Start an interactive session by running `claude` in your terminal.
2. You'll be prompted to log in on first use — complete authentication in your browser.
3. To switch accounts later, type `/login` inside the running session.

### Step 3: Navigate to Your Project
1. `cd` to your project directory.
2. Run `claude` to start a session in that project.

### Step 4: Basic Usage
1. **Ask Questions**: `claude "Explain this codebase"`
2. **Make Changes**: `claude "Add error handling to this function"`
3. **Search Code**: `claude "Find all API endpoints"`
4. **Generate Code**: `claude "Create a new React component"`
