# Overview

Claude Code is Anthropic's official CLI AI coding assistant powered by Claude, capable of understanding project context, generating code, explaining code, and performing Git operations.

## Installation

```bash
# macOS/Linux
npm install -g @anthropic-ai/claude-code

# Verify
claude --version
```

## Permission Configuration

Claude Code requires explicit permissions for sensitive operations:

### Permission Levels

| Operation | Default | Description |
|-----------|---------|-------------|
| Read files | Auto | Can read all files |
| Write files | Confirm | User confirmation required |
| Execute commands | Confirm | Terminal commands need confirmation |
| Git operations | Confirm | commit/push require confirmation |

### Configuration

```bash
# Allow all commands
claude --dangerously-permit-commands all

# Read-only mode
claude --read-only
```

## Core Commands

### /help - Help

```bash
claude
/help  # Show all available commands
```

### /lsp - Code Understanding

```bash
/lsp find readFile
/lsp explain src/utils.js
```

### /web - Web Search

```bash
/web how to use React hooks
```

### /commit - Git Commit

```bash
/commit  # Auto-analyze changes and generate commit message
```

## MCP Integration

Claude Code supports Model Context Protocol for external tools:

```json
// ~/.claude/settings.json
{
  "mcpServers": {
    "filesystem": {
      "command": "npx",
      "args": ["-y", "@anthropic/mcp-server-filesystem", "/path/to/dir"]
    }
  }
}
```

## Best Practices

1. **CLAUDE.md**: Create CLAUDE.md in project root for project specs
2. **Permission Control**: Use read-only mode in production
3. **Context Management**: Use /clear for large projects
