🔧 Installation Guides

VSCode Integration

Official Extension Installation

# Method 1: Via Claude Code CLI
claude install-extension vscode
 
# Method 2: From VSCode Marketplace
# Search for "Claude Code" by Anthropic
# Click Install

Key Features

• Quick Launch: Cmd+Esc (Mac) or Ctrl+Esc (Windows/Linux)
• Inline Edits: Code changes appear directly in your editor
• Selection Context: Automatically shares current selection with Claude
• File References: Cmd+Option+K (Mac) or Alt+Ctrl+K (Linux/Windows) to insert file refs
• Diagnostic Sharing: Lint and syntax errors automatically shared

Cursor IDE Integration

Despite being VSCode-based, Cursor requires manual installation due to detection issues.

Manual Installation (100% Success Rate)

# Install the VSIX extension manually
cursor --install-extension ~/.claude/local/node_modules/@anthropic-ai/claude-code/vendor/claude-code.vsix

Cost Optimization

• Cursor adds 20% markup to API usage
• Consider using Claude Code directly for intensive development
• Claude Code is ~4x more expensive but produces 30% less code churn

JetBrains Integration

Plugin Installation

1. Open Settings → Plugins
2. Search for “Claude Code [Beta]”
3. Install and restart IDE
4. Launch with Cmd+Esc (Mac) or Ctrl+Esc (Windows/Linux)

Alternative: JetBrains AI Assistant

• Supports Claude models via Amazon Bedrock
• Available in IDE version 24.3.2+
• Requires AI Assistant subscription (separate from Claude API)

🎨 Integration Patterns

Pattern 1: Context-Aware Code Generation

// Example: Using IDE selection context
// 1. Select code in IDE
// 2. Launch Claude Code (Cmd+Esc)
// 3. Claude automatically sees selected code
 
// Selected function needing optimization
function processData(items: any[]) {
  // Claude will see this selection and can refactor
  for (let i = 0; i < items.length; i++) {
    // Processing logic
  }
}

Pattern 2: Inline Diff Review

# Claude Code shows changes in IDE diff viewer
# Benefits:
- Visual comparison of changes
- Accept/reject individual hunks
- Version control integration
- No context switching

Pattern 3: Multi-File Refactoring

// Use file reference shortcuts
// @src/services/auth.ts#L45-89
// @src/models/user.ts
// Claude can refactor across multiple files

🚀 Advanced Integration Techniques

Custom Keybindings

// VSCode keybindings.json
{
  "key": "cmd+shift+a",
  "command": "claude-code.askQuestion",
  "when": "editorTextFocus"
}

Workspace Settings

// .vscode/settings.json
{
  "claude-code.autoContext": true,
  "claude-code.includeOpenTabs": true,
  "claude-code.diagnosticLevel": "error"
}

IDE-Specific Hooks

# Configure hooks for IDE events
claude hooks add --event "pre-commit" --command "claude review"

🔍 Troubleshooting

Common Issues

VSCode: Extension Not Loading

# Verify Claude Code is installed
claude --version
 
# Reinstall extension
claude install-extension vscode --force

Cursor: Detection Failure

# Cursor not recognized as VSCode
# Use manual VSIX installation method above

JetBrains: Plugin Compatibility

# Check IDE version (needs 24.3.2+)
# Update IDE if necessary

💡 Best Practices

1. Context Management

   • Keep relevant files open in tabs
   • Use file references for precision
   • Clear diagnostics before complex refactoring

2. Performance Optimization

   • Close unnecessary files to reduce context
   • Use selection for targeted assistance
   • Enable prompt caching for repetitive tasks

3. Security Considerations

   • Review all generated code before accepting
   • Use .claudeignore for sensitive files
   • Configure workspace-specific settings
