## Best Practices

### VS Code

**Workspace Organization:**
- Use workspace settings for team consistency
- Share .vscode/claude.json in version control
- Document custom shortcuts
- Configure output styles per project

**Performance:**
- Limit inline suggestions in large files
- Disable auto-save for better control
- Use specific prompts
- Close unused editor tabs

### JetBrains

**Project Configuration:**
- Enable Claude for specific file types only
- Configure inspection severity
- Set up custom code review templates
- Use project-specific skills

**Performance:**
- Adjust auto-complete delay
- Limit scope of code analysis
- Disable for binary files
- Configure memory settings

## Troubleshooting

### VS Code

**Extension Not Loading:**
```bash
# Check extension status
code --list-extensions | grep claude

# Reinstall
code --uninstall-extension anthropic.claude-code
code --install-extension anthropic.claude-code
```

**Authentication Issues:**
- Verify API key in settings
- Check environment variable
- Re-authenticate in extension
- Review proxy settings

### JetBrains

**Plugin Not Responding:**
```
File → Invalidate Caches / Restart
Settings → Plugins → Claude Code → Reinstall
```

**Performance Issues:**
- Increase IDE memory (Help → Edit Custom VM Options)
- Disable unused features
- Clear caches
- Update plugin version
