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:

# Check extension status
code --list-extensions | grep claude

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

Authentication Issues:
