Django Debugging & Optimization

About

The debug-django skill empowers Claude with a comprehensive framework for identifying and resolving the most common and challenging errors within the Django ecosystem. It covers a wide spectrum of issues including TemplateDoesNotExist, CSRF failures, circular imports, and complex migration conflicts.
