Django Rest Framework

This one gives Claude the patterns for building Django REST Framework APIs with proper serializers, viewsets, and routing. You get examples for ModelSerializer configurations with custom fields and validation, nested serializers for complex relationships, and ViewSet implementations with custom actions like publish and recent endpoints. It covers permission classes like IsAuthorOrReadOnly, router setup with DefaultRouter, and practical stuff like handling base64 images and writable nested data. Useful when you're building RESTful APIs and want Claude to follow DRF conventions instead of writing everything from scratch. The examples show real world scenarios like prefetching relations and dynamic serializer selection.
